The camera 153 may be used to capture still images or video. Illustratively, as shown in fig. 2, the camera 153 includes a lens and an image sensor. The lens is used for converging light rays so as to collect optical images. The object is projected to the image sensor to be imaged through an optical image collected by the lens. The lens may be a standard lens, an anamorphic lens, or a lens with other characteristics, which is not limited. The standard lens images the acquired image on the image sensor in an equal proportion, that is, the proportion of the image acquired by the standard lens in the width direction and the height direction is the same as the proportion of the image in the width direction and the height direction after the image is imaged on the image sensor. Unlike a standard lens, an optical image captured by an anamorphic lens is compressed in the width direction and then appears on an image sensor. For example, as shown in fig. 3, the range acquired by the anamorphic lens in the width direction is the range shown in the image 301, the range acquired in the height direction is the range shown in the image 301, and the image 302 is the image after the anamorphic lens images the image 301 onto the image sensor. As can be seen in fig. 3, image 302 is compressed in the width direction but uncompressed in the height direction compared to image 301.

It should be noted that in the embodiment of the present application, the electronic device may include one or N cameras 153, where N is a positive integer greater than or equal to 2.

Taking fig. 4 as an example, the lenses of the camera 153A, the camera 153B, the camera 153C, the camera 153D and the camera 153E may all be standard lenses, or may be partially standard lenses, and the other part is an anamorphic lens. For example, the lenses of the

cameras

153A, 153C, and 153E are standard lenses, and the lenses of the cameras 153B and 153D are anamorphic lenses. When the electronic equipment shoots a wide-frame image, the anamorphic lens is used for collecting the image, so that the subsequent image processing process is facilitated to be simplified, and more contents are presented in the image shot by the electronic equipment.

It should be noted that the anamorphic lens may also be referred to as an anamorphic wide-screen lens. The image sensor may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The image sensor converts the optical signal into an electrical signal and then delivers the electrical signal to the ISP.

Upon receipt of the electrical signal, the ISP can convert the electrical signal into a digital image signal having an aspect ratio that meets the resolution selected by the user. The ISP may send the digital image signal to the image processor for post-image processing, such as video color enhancement, video denoising, and the like. The image processor may be a DSP or other device for performing image processing. In addition, the ISP can also directly perform post-image processing after obtaining the digital image signal, such as performing algorithm optimization on noise, brightness, and color of the image. In some embodiments, the ISP may also optimize parameters such as exposure, color temperature, etc. of the shooting scene. In some embodiments, the ISP may be provided in an image sensor in the camera 153. After the digital image signal is processed by the later image processing, the processed digital image signal is output to a video coder-decoder for compression coding. The video codec may convert the digital image signal into an image signal in a standard RGB, YUV, or the like format and then output it, for example, the video codec may present the output image signal on the display screen 151, or the video codec may save the output image signal to the internal memory 121 or an external memory connected to the external memory interface 122.

The keys 154 may include a power-on key, a volume key, and the like. The keys 154 may be mechanical keys. Or may be touch keys. The electronic device may receive a key input, and generate a key signal input related to user settings and function control of the electronic device.

The gyro sensor 160C may be used to determine the motion pose of the electronic device. In some embodiments, the angular velocity of the electronic device about three axes (i.e., x, y, and z axes) may be determined by gyroscope sensor 160C. The gyro sensor 160C may be used for photographing anti-shake. For example, when the shutter is pressed, the gyroscope sensor 160C detects a shake angle of the electronic device, calculates a distance to be compensated for by the lens module according to the shake angle, and allows the lens to counteract the shake of the electronic device through a reverse movement, thereby achieving anti-shake. The gyro sensor 160C may also be used for navigation, body sensing game scenes.

The pressure sensor 160D is used for sensing a pressure signal, and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 160D may be disposed on the display screen 151. The pressure sensor 160D may be of various types, such as a resistive pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, and the like. The capacitive pressure sensor may be a sensor comprising at least two parallel plates having an electrically conductive material. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronics determine the strength of the pressure from the change in capacitance. When a touch operation is applied to the display screen 194, the electronic device detects the intensity of the touch operation according to the pressure sensor 180A. The electronic device may also calculate the position of the touch from the detection signal of the pressure sensor 180A. In some embodiments, the touch operations that are applied to the same touch position but different touch operation intensities may correspond to different operation instructions. For example: and when the touch operation with the touch operation intensity smaller than the first pressure threshold value acts on the short message application icon, executing an instruction for viewing the short message. And when the touch operation with the touch operation intensity larger than or equal to the first pressure threshold value acts on the short message application icon, executing an instruction of newly building the short message.

The acceleration sensor 160E can detect the magnitude of acceleration of the electronic device in various directions (typically three axes). When the electronic device is at rest, the magnitude and direction of gravity can be detected. The method can also be used for recognizing the posture of the electronic equipment, and is applied to horizontal and vertical screen switching, pedometers and other applications.

For example, the resolution of the image 302 as shown in fig. 3 is 640 × 480, where 640 is the pixel value of the image 302 in the width direction and 480 is the pixel value of the image 302 in the height direction. The resolution of image 302 has an aspect ratio of 640/480-4: 3. It is understood that the aspect ratio may also be referred to as an aspect ratio or a picture ratio, etc.

The embodiment of the application can be applied to the application with the shooting function, such as a camera, an instant message with a video function and the like. The method of the embodiment of the present application will be described in detail by taking a camera as an example.

Illustratively, the display screen 151 of the electronic device displays a home interface, wherein the home interface includes a camera icon. By way of example, the main interface may be the user interface 500 shown in FIG. 5. Therein, user interface 500 includes a camera icon 501. In addition, the user interface 500 may include icons for other applications, such as a settings icon, a memo icon, a gallery icon, and the like. In some embodiments, user interface 500 may also include a status bar 502, a concealable navigation bar 504, and a Dock bar 503. The status bar 502 may include a name of an operator (e.g., china mobile, etc.), a mobile network (e.g., 4G), a bluetooth icon, time, and remaining power. Further, it is understood that in other embodiments, a WiFi icon, an add-on icon, etc. may also be included in the status bar 502. The navigation bar 504 may include a back button (back button), a home screen button (home button), and a history task view button (menu button). Icons for common applications, such as phone icons, information icons, mail icons, and weather icons, may be included in Dock bar 503. It should be noted that the icons in the Dock column may be set according to the needs of the user.

The electronic device may respond to the first operation, start an application corresponding to the camera icon 501, and display a preview interface on the display screen 151, where an image captured by the camera 153 is displayed on the preview interface. It is understood that the electronic device may also turn on the camera 153 in response to the first operation. In addition, the camera 153 may be always on. It should be understood that the application corresponding to the camera icon 501 may be referred to as a camera, and may also be referred to by other names, which are not limited. The following embodiment refers to the application to which the camera icon 501 corresponds as a camera. The first operation may be an operation on the camera icon 501, an operation on a voice instruction of the user (for example, "turn on the camera"), or a shortcut gesture operation (for example, three fingers slide down). Here, the operation on the camera icon 501 may be a touch operation, a press operation, or the like on the camera icon 501. In addition, in the embodiment of the application, when the electronic equipment is in a blank screen state or a screen locking state. The camera may be started in response to a voice instruction or a shortcut gesture operation of the user, and a preview interface may be displayed on the display screen 151.

In particular implementations, in some embodiments, the preview interface may be a photo preview interface. Illustratively, the user interface 510 is shown in FIG. 5. Taking the rear camera as an example, the user interface 510 displays the image captured by the rear camera of the electronic device. In other embodiments, the user interface 510 may also display images captured by a front-facing camera of the electronic device. In other embodiments, the preview interface may be a video preview interface. An exemplary video preview interface may be the user interface 520 shown in fig. 5. Taking the rear camera as an example, the user interface 520 displays a video image captured by the rear camera of the electronic device. In other embodiments, the user interface 520 displays video images that may also be captured for a front facing camera of the electronic device. It should be noted that the electronic device according to the embodiment of the present application may implement switching between the front camera and the rear camera in response to an operation of the camera switching button 514 shown in fig. 5.

The following description will take an example in which the electronic device responds to the first operation, displays the user interface 510 on the display screen 151, and the image displayed by the user interface 510 is captured by a rear camera of the electronic device. In some embodiments, as shown in FIG. 5, user interface 510 may also include a shooting mode selection button area 511, which may include a take, record, professional, portrait, large aperture, night view, or more mode selection buttons. The user can view the photographing mode of the electronic device by sliding left and right in the photographing mode selection button region 511. The electronic device may display a user interface 520 on the display screen 151 in response to an operation of selecting a video recording on the user interface 510. The user interface 520 displays a video image acquired by the rear camera. Specifically, the electronic device is based on the resolution set by the user to display a video image captured by the rear camera on the user interface 520. It should be understood that the user may set the resolution on the setup interface of the video. In some embodiments, user interface 520 includes a set button 521. The electronic apparatus can display a setting interface of the video on the display screen 151 in response to an operation of the setting button 521 by the user. In other embodiments, the electronic device may also display a setting interface for the video in response to a user sliding left or right on the user interface 520. It should be noted that the electronic apparatus may also display a setting interface of the video on the display screen 151 in response to other operations (e.g., operations of pulling down, sliding up, etc.). By way of example, the setup interface for a video may be as shown in the user interface 610 shown in FIG. 6. The user interface 610 includes a resolution setting button 611. From the resolution setting button 611, it can be seen that the resolution of the image currently selected by the user is 640 × 480, wherein in the case of the resolution of 640 × 480, the aspect ratio is 4: 3. The user interface 520 displays a video image with a resolution having an aspect ratio of 4: 3. Typically, the electronic device displays an image having a 4:3 aspect ratio in a portrait screen for easy viewing by a user, such as the user interface 520 shown in FIG. 5. The electronic device may also display the user interface 520 across the screen, for example, as shown in fig. 7 a.

The electronic device may display a user interface 620 on the display screen 151 in response to operation of the resolution option button 611. The user interface 620 includes options for multiple video resolutions supported by the electronic device, such as 4K UHD 3840 × 2160, 1080P FHD + (18:9)2160 × 1080, 1080P FHD (60fps)1920 × 1080, 1080P FHD + (21:9)2560 × 1080, 720P HD + (21:9)1680 × 720, 720P 1280 × 720, VGA (4:3)640 × 480, QVGA (4:3)320 × 240. As can be seen from the user interface 620 shown in fig. 6, the resolution of the video with the aspect ratio of 21:9 may be 1080P FHD + (21:9)2560 × 1080 and 720P HD + (21:9), it should be noted that the resolution of the video with the aspect ratio of 21:9 may also be UHD +4K 5040 × 2160, and the user interface 620 shown in fig. 6 of the present application is only a schematic diagram and does not constitute a limitation to the embodiments of the present application. The electronic device in the embodiment of the present application may support resolutions such as aspect ratios of 2.37:1(64:27), 2.39:1 (12: 5), 2.55:1 (23: 9), 2.59:1 (13: 5), and 2.66:1(8:3, 24:9) in addition to resolutions such as aspect ratios of 4:3, 16:9, and 21:9, and the aspect ratio of the resolution supported by the electronic device is not limited in the embodiment of the present application.

The user can select the corresponding resolution according to the requirement of the user. For example, the electronic device may set the resolution of the image when the video was captured to 2560 × 1080 in response to the user selecting an option of 2560 × 1080 resolution. In some embodiments, user interface 620 also includes a back button 621 to facilitate user operation, exiting user interface 620. Accordingly, the electronic device may exit user interface 620 and return to user interface 610 in response to operation of return button 621. In this case, the resolution setting button 611 included in the user interface 610 displays a resolution update of 2560 × 1080. In other embodiments, the electronic device may also exit the user interface 620 and return to the user interface 610 in response to a shortcut gesture operation (e.g., a swipe left on the user interface 620, etc.). The user interface 610 may also include a back button 612 to facilitate user operation to exit the user interface 610. For example, if the electronic device is entered through the setting button 521 included in the user interface 520, the electronic device may exit the user interface 610 and display a preview interface of the video in response to an operation of the return button. Since the current resolution of 2560 x 1080 has an aspect ratio of 4:3 for a resolution of 640 x 480 and 21:9 for a resolution of 2560 x 1080 as compared to a resolution of 640 x 480 when the user interface 520 is displayed by the display screen 151, in some embodiments, the electronic device may display the video image landscape in response to the resolution being set to 2560 x 1080, thereby facilitating a better display of the video image with a resolution of 2560 x 1080. For example, after the electronic device exits the user interface 610, the displayed photo preview interface may be the user interface 700 shown in FIG. 7 b. The video image collected by the rear camera is displayed in the user interface 700, and the resolution of the video image is 2560 × 1080.

In another embodiment, at least one of a zoom option area 704, a video color selection button 701, a high dynamic range button 702, a flash button 703, and a video mode selection button 705 may also be included on the user interface 700. For example, the electronic device may set a zoom factor used in shooting in response to selecting the zoom factor in zoom option area 704. As shown in fig. 7b, the zoom factor currently selected by the user is × 1. In some embodiments, the zoom factor options included in the zoom option area 704 may include x 5, x 3, x 1, x 0.75, and so on. It should be noted that, because the zoom factor is increased, the long-range view can be zoomed in, the range of the captured image is small, but the zoom factor is reduced, the range of the captured image can be expanded, and the captured image can display a larger picture. Therefore, in some embodiments, taking the rear-facing camera as an example, if the electronic device includes two or more rear-facing cameras and the focal lengths of the different rear-facing cameras are different, the electronic device may perform the switching of the rear-facing cameras in response to the different zoom multiples selected by the user. Thereby facilitating the acquisition of the image. Illustratively, the electronic device includes 3 rear cameras, wherein the focal lengths of the 3 rear cameras are 3.6mm, 4mm and 6mm, respectively, then when the electronic device responds to a user-selected zoom factor of x 0.75, the rear camera having a focal length of 3.6mm is turned on. When the electronic equipment starts the rear camera with the focal length of 3.6mm, the electronic equipment can respond to the fact that a user selects the zoom multiple to be multiplied by 1, and switches to the rear camera with the focal length of 4mm, so that the electronic equipment can acquire images based on the rear camera with the focal length of 4 mm. As another example, the electronic device switches to a 6mm rear camera when the zoom factor is x 3 or x 5 in response to a user selection.

The electronic device may display options of video colors, such as standard, bright, soft, etc., on the display screen 151 in response to user manipulation of the video color selection button 701. The electronic device may set the color of the captured video in response to the user's selection of the video color. The electronic device may turn the high dynamic range setting on or off in response to user operation of the high dynamic range button 702. The electronic device may turn the flash on or off in response to user operation of the flash off button 703.

In addition, the electronic apparatus may also set a mode of capturing video in response to an operation of the video mode selection button 705. The video mode may include portrait blurring, AI color, and neutral mode, among others. For example, the electronic device may display a video mode selection menu at the user interface 700 in response to operation of the video mode selection button 705. Wherein different video modes may be included in the video mode selection menu. For example, as shown in fig. 7c, the video modes included in the video mode selection menu 707 are: none, AI color, portrait blurring, nostalgia, suspicion, and freshness. The user can select a corresponding video mode from the video mode selection menu 707 according to the requirement of the user. It should be noted that, in some embodiments, the video modes included in the video mode selection menu 707 may further include video modes other than those displayed on the user interface 700 shown in fig. 7c, that is, when the video modes included in the video mode selection menu 707 cannot be all displayed on the display screen 151, the user may select one video mode according to his/her selection by sliding up and down in the video mode selection menu 707 to view the video modes. Therefore, the electronic equipment can respond to different modes selected by a user to realize different processing on video images collected by the camera. For example, when the user selects a character blurred video mode, the electronic device may perform character blurring on a video image captured by the camera in response to the user selected character blurred video mode. In some embodiments, the electronic device may hide the video mode selection menu 707 in response to a user-selected character blurring video mode, or in response to operation of the video mode selection button 705, or other operation. In addition, in some embodiments, when the electronic device includes multiple cameras, different cameras may also be turned on in response to different modes being selected, thereby enabling the electronic device to facilitate image processing. For example, the electronic device includes two rear cameras, and when a user selects a video mode of an AI color, the two rear cameras can be turned on simultaneously, and then the images collected by the two rear cameras are processed and displayed on the video preview interface.

For example, when the electronic device includes a rear camera, in the case that the lens of the rear camera is a standard lens, if an image captured by the lens of the rear camera has a ratio of 4:3 in the width direction and the height direction and an image imaged behind the image sensor has a ratio of 4:3 in the width direction and the height direction, the electronic device may capture a video image having a resolution of 2560 × 1080 based on the following method.

The first embodiment is as follows: the image sensor can send a 4:3 image to the ISP, and after the ISP receives the 4:3 image, the image collected by the rear camera is cut into 21:9 in the width direction and the height direction according to the resolution 2560X 1080 selected by the user, and then the image is scaled into an image with the resolution 2560X 1080. The 2560 × 1080 resolution image is then sent by the ISP to an image processor for processing, such as denoising, color adjustment, etc. After the image processor completes processing the image, the processed image is sent to a video codec, which encodes the image into a corresponding file format (e.g., MP4, 3GP, etc.) and displays it on the display screen 151. The electronic device may start capturing a 2560 × 1080 resolution video image using the rear camera in response to a user's operation of the shooting button 513 or other shortcut operations (e.g., voice instruction, pressing a volume key, etc.), and store the video image in the internal memory 121 or an external memory connected to the external memory interface 122. In some embodiments, the electronic device may display a video recording interface on the display screen 151 in response to user operation of the capture button 513. For example, the rear camera collects images, and the images collected by the rear camera are displayed on the video recording interface. For example, the video recording interface may be the user interface 710 shown in fig. 7 d. For example, the user interface 710 may include a recording time. In some embodiments the user interface 710 includes at least one of a take button 513, a pause button 711, and a take button 712. The electronic apparatus 100 may end recording the video and save the recorded video in response to the operation of the photographing button 513 during the recording of the video. In some embodiments, the electronic device 100 displays a video preview interface on the display screen 151 after finishing recording the video. The electronic device may pause the recording of the video in response to operation of the pause button 711 during the recording of the video. The recording of the video may also be continued in response to the operation of the pause button 711 after the electronic device is pausing the recording of the video. The electronic device may take a picture of the currently recorded video and save the taken picture in response to the operation of the take picture button 712. For example, as shown in fig. 7d, the current time for recording the video is 00:07, and if the electronic device responds to the operation of the photographing button 712 at the time 00:07, the electronic device photographs the video image captured at the time 00:07 and stores the photographed image.

In some embodiments, the electronic device may further implement a focusing operation in the process of recording the video in response to an operation of the image by the user. Illustratively, as shown in fig. 7d, in response to the user touching position a on the display screen 151, the electronic device displays a focusing frame 713. It should be noted that the position a may be any position on the user interface 710 other than the function button. In some embodiments, the electronic device may also display a brightness adjustment bar 714 in response to the user touching location a on the display screen 151. The electronic device may adjust the brightness of the display screen 151 in response to an operation of sliding the brightness adjustment button 715 up or down. In addition, the electronic equipment can respond to the zooming gesture operation of the user on the image to realize zooming.

In the embodiment of the present application, the ISP may obtain the resolution selected by the user based on the following manner: in some embodiments, the touch sensor 160A of the electronic device may report information (e.g., coordinates, etc.) operated by the user on the display screen 151 to the application processor after receiving an operation of 2560 × 1080 resolution selected by the user, and the application processor determines to update the resolution of the photographed image to 2560 × 1080 according to the information operated by the user on the display screen 151. The application processor then informs the ISP of the updated resolution 2560 x 1080 so that the ISP can process the images acquired by the rear camera based on the resolution selected by the user. In other embodiments, the touch sensor 160A of the electronic device may also directly report information of the user's operation on the display screen 151 to the ISP, and the ISP may determine the resolution of the photographed image based on the information of the user's operation on the display screen 151. The embodiment of the present application does not limit the manner in which the ISP obtains the resolution selected by the user.

Example two: the image sensor may cut the 4:3 image into a 21:9 image according to the resolution 2560 × 1080 selected by the user and transmit the image to the ISP. After receiving the 21:9 image, the ISP scales the 21:9 image to an image of 2560 × 1080 resolution selected by the user, and then the 2560 × 1080 image is subsequently processed by the image processor and codec. It should be noted that the image sensor may obtain the resolution selected by the user from the ISP, and in addition, the manner in which the image sensor obtains the resolution selected by the user may also refer to the manner in which the ISP obtains the resolution selected by the user in the first embodiment.

Example three: the image sensor may crop the 4:3 image into a W: H image according to the user selected resolution 2560 x 1080, where W: h is 4: a ratio between 3 and 21:9, such as W: h may be 16: 9. The image sensor compares W: the image of H is sent to the ISP. After receiving the W: H image, the ISP crops the W: H image into a 21:9 image according to the resolution 2560 × 1080 selected by the user, scales the 21:9 image into a 2560 × 1080 resolution image, and then performs subsequent processing on the 2560 × 1080 image by the image processor and the codec.

It should be noted that, in the third embodiment, a manner in which the image sensor acquires the resolution selected by the user may be referred to as a manner in which the image sensor acquires the resolution selected by the user in the second embodiment. The manner in which the ISP acquires the resolution selected by the user in the second embodiment and the third embodiment may be referred to as the manner in which the image sensor acquires the resolution selected by the user in the first embodiment. The manner in which the image processor and codec performs subsequent processing on the 2560 × 1080 image in the second embodiment and the third embodiment can be seen in the manner in which the image processor and codec performs subsequent processing on the 2560 × 1080 image in the first embodiment.

It should be noted that, the above is described by taking as an example that the ratio of the image acquired by the lens of the rear camera in the width direction to the image acquired by the lens of the rear camera in the height direction is 4:3, and the ratio of the image imaged after the image sensor in the width direction to the image acquired by the rear camera in the height direction is 4:3, and when the ratio of the image imaged after the image sensor in the width direction to the image acquired by the rear camera in the height direction is smaller than or larger than the aspect ratio of the resolution selected by the user, the shooting method can be referred to embodiments one to three. When the proportion of the width direction to the height direction of an image formed by light rays collected by the lens of the rear camera after the image sensor is equal to the length-width ratio of the resolution selected by the user, the image collected by the rear camera does not need to be cut, and the image collected by the camera is directly zoomed into the image of the resolution selected by the user by the ISP. For example, the resolution selected by the user is 2560 × 1080, and the ratio of the width direction to the height direction of the image formed by the light collected by the lens of the rear camera behind the image sensor is 21:9, the ISP can directly scale the received 21:9 image from the image sensor to the 2560 × 1080 resolution image.

In addition, in some embodiments, the electronic device may further automatically start a skin beautifying function in response to detecting that the rear camera captures a face image of the user. For example, when an image acquired by a rear camera of the electronic device is the image 301 in fig. 3, a skin beautifying function is automatically turned on to beautify the face (e.g., scrub, remove acne, etc.). In addition, taking the user interface 700 shown in fig. 7b as an example, the user interface 700 further includes a skin makeup function button 706, and the electronic device may activate a skin makeup function in response to an operation of the skin makeup function button 706. For example, the electronic device may display a skin-makeup level on the display screen 151 in response to an operation of the skin-makeup function button 706. The user can set the skin beautifying grade according to the needs of the user.

For example, when the electronic device includes a rear camera, in the case that the lens of the rear camera is an anamorphic lens, if the ratio of the width direction to the height direction of the image captured by the lens of the rear camera is 21:9 and the ratio of the width direction to the height direction of the image imaged behind the image sensor is 4:3, the electronic device may capture a video image with a resolution of 2560 × 1080 based on the following method.

Example four: the image sensor may send a 4:3 image to the ISP. After the ISP receives the 4:3 image, the 4:3 image collected by the rear camera is stretched in the width direction according to the resolution 2560X 1080 selected by the user, so that an image with the ratio of the width direction to the height direction being 21:9 is obtained, and then the image is zoomed into the image with the resolution 2560X 1080. The 2560 × 1080 images are then subsequently processed by an image processor and codec.

Example five: the image sensor may stretch the 4:3 image 4:3 in the width direction according to the resolution 2560 × 1080 selected by the user, obtain an image with a ratio of 21:9 in the width direction and the height direction, and transmit the image to the ISP. After receiving the 21:9 image, the ISP scales the 21:9 image to an image of 2560 × 1080 resolution selected by the user, and then the 2560 × 1080 image is subsequently processed by the image processor and codec.

It should be noted that, in the fifth embodiment, a manner in which the image sensor can obtain the resolution selected by the user from the ISP can be referred to as a manner in which the image sensor obtains the resolution selected by the user in the second embodiment. In the fourth and fifth embodiments, the manner in which the ISP acquires the resolution selected by the user may be referred to as the manner in which the image sensor acquires the resolution selected by the user in the first embodiment. The way in which the image processor and codec performs subsequent processing on the 2560 × 1080 image in the fourth embodiment and the fifth embodiment can be seen in the way in which the image processor and codec performs subsequent processing on the 2560 × 1080 image in the first embodiment.

The above description is given by taking an example in which the ratio of the image captured by the anamorphic lens in the width direction to the image captured by the anamorphic lens in the height direction is 21:9, and the ratio of the image imaged on the image sensor in the width direction to the image captured by the anamorphic lens in the height direction is 4: 3. In general, the ratio of the image acquired by the anamorphic lens in the width direction and the height direction is the same as the ratio of the resolution selected by the user, and in this case, the image with the ratio of the resolution process selected by the user can be obtained only by stretching the image imaged on the image sensor. When the ratio W1 of the image captured by the anamorphic lens in the width direction and the height direction: h1 and user selected resolution ratio W2: when H2 is different, the image imaged on the image sensor may be stretched into W1: image of H1, then for W1: the image of H1 was cropped to obtain W2: images of H2. The stretching and clipping operations may be performed by the image sensor, the stretching and clipping operations may be performed by the ISP, the stretching operation may be performed by the image sensor, and the clipping operation may be performed by the ISP.

In some embodiments, when the electronic device switches from the rear camera to the front camera for shooting in response to the operation of the camera switch button 514, if there is only one front camera and the shot of the front camera is a standard shot, the mode of shooting the image may refer to the shooting mode of the rear camera.

In addition, when the electronic device includes a plurality of cameras, if the lenses of the cameras included in the electronic device are the same, for example, all the lenses of the cameras included in the electronic device are standard lenses, the shooting method may refer to the related descriptions in the first to third embodiments. When the cameras included in the electronic device are all anamorphic lenses, the shooting method can refer to the related descriptions in the fourth embodiment and the fifth embodiment.

In some embodiments, the electronic device may include cameras of different lenses. For example, as shown in fig. 8, the electronic apparatus includes a rear camera 801 and a rear camera 802. The lens of the rear camera 801 is a standard lens, and the lens of the rear camera 802 is an anamorphic lens. In this case, when the electronic device uses the rear camera to shoot, the rear camera can be started according to the resolution selected by the user. The shooting method of the electronic device after the rear camera is started can be seen in the first to fifth embodiments.

The rear camera 801 is a standard lens, the ratio of the image acquired by the standard lens in the width direction to the image acquired by the standard lens in the height direction is 4:3, and the ratio of the image imaged behind the image sensor in the width direction to the image acquired by the standard lens in the height direction is 4: 3; the lens of the rear camera 802 is an anamorphic lens, and the ratio of the anamorphic lens to the width direction and the height direction of the acquired image is 21:9, and the ratio of the image imaged behind the image sensor to the width direction and the height direction is 4: 3.

In some embodiments, the electronic device may activate the rear-facing camera based on a user selected resolution. For example, the electronic device may activate rear-facing camera 801 when the aspect ratio of the resolution selected by the user is 4: 3. In some embodiments, the electronic device may also prompt the user for a started rear camera. For example, the electronic device may prompt the user that the lens of the rear camera currently used is a standard lens in a voice manner. As another example, the electronic device may also display a prompt box on the display screen 151. The prompt box includes a prompt that the lens of the camera currently used by the user is an anamorphic lens. For example, as shown in fig. 9, the electronic device displays a prompt box 900 on the display screen 151, where the prompt box 900 includes a prompt message "the lens of the rear camera that is started is a standard lens". In other embodiments, the electronic device activates rear-facing camera 802 when the aspect ratio of the resolution selected by the user is 21: 9. The technical scheme is beneficial to enabling the visual field range of the 21:9 image shot by the electronic equipment to be larger. Illustratively, the electronic device activates the rear camera 802 in response to a user selecting a resolution with an aspect ratio of 21: 9. In this case, the electronic device may prompt the user that the lens of the rear camera currently used is the anamorphic lens. The specific prompting mode may refer to a prompting mode for prompting that a lens of a rear camera currently used by a user is a standard lens.

It should be noted that, since the aspect ratio of the resolution supported by the electronic device may include a plurality of types, for example, 16:9, 4:3, 2:1, 21:9, 2.37:1(64:27), 2.39:1 (12: 5), 2.55:1 (23: 9), 2.59:1 (13: 5), 2.66:1(8:3, 24:9), etc., the number of cameras configured on the electronic device is limited, currently, a maximum of 3 rear cameras are configured on the electronic device, and in some embodiments, the electronic device may start a camera with a standard lens when the aspect ratio of the resolution selected by the user is smaller than the first threshold; and when the resolution selected by the user is greater than or equal to the first threshold, starting the camera with the lens as the anamorphic lens. The first threshold may be set accordingly as needed, for example, the first threshold may be set to 2, may also be set to 7/3, and the like. Optionally, a lens in the rear camera configured on the electronic device includes a first lens, and when a ratio of an image acquired by the first lens in the width direction and the height direction is the same as a length-width ratio of a resolution selected by a user, the rear camera including the first lens is started. Therefore, the subsequent image processing is facilitated to be simplified, and the image processing efficiency is improved.

It should also be noted that in some embodiments, the electronic device may also turn on different cameras in response to different modes. The electronic device takes a picture by using a rear camera, and the rear camera included in the electronic device is as shown in fig. 8. For example, when the aspect ratio of the resolution selected by the user is 21:9 and the video mode selected by the user is the portrait mode, the electronic device may turn on the rear camera 802 and the rear camera 801, where a lens of the rear camera 802 is an anamorphic lens and a lens of the rear camera 801 is a standard lens. When the electronic device is used for shooting, the image collected by the rear camera 802 can be processed to obtain an image with an aspect ratio of the resolution selected by the user, and then the processed image selected by the user and the image collected by the rear camera 802 are synthesized, so that people in the shot video can be more prominent. The above description is made only by taking the portrait mode as an example of the manner of turning on the rear camera. For different video modes, the mode of turning on the camera may be set based on actual conditions, which is not limited herein.

In addition, when the electronic device uses the front camera to shoot, the shooting method can refer to the shooting mode of the rear camera.

The embodiment of the application can also be applied to a photographing scene. Take the example of the user interface 510 shown in fig. 5. The electronic device is based on the user-set resolution of the camera captured image displayed at the user interface 510. For example, the user may set the image resolution by taking a picture on a setting interface. In some embodiments, user interface 520 includes a set button 521. The electronic device may display a setting interface for photographing in response to an operation of the setting button 515 by the user. In addition, the electronic equipment can also respond to the leftward or rightward sliding operation on the photographing preview interface, and the setting interface for photographing can be displayed. In this embodiment of the application, the electronic device may further display a setting interface for taking a picture in response to other operations (for example, operations such as pull-up or pull-down). For example, the settings interface for the photograph can be as shown in the user interface 1010 of FIG. 10. The user interface 610 includes a resolution setting button 1011. It can be seen from the resolution setting button 1011 that the resolution of the image currently selected by the user is 3968 × 2976, wherein in the case of the resolution of 3968 × 2976, the aspect ratio is 4: 3. The user interface 510 displays a video image with a resolution having an aspect ratio of 4: 3.

The electronic device may display a user interface 1020 on the display screen 151 in response to operation of the resolution option button 1011. The user interface 1020 includes options for the resolution of the plurality of images supported by the electronic device. The user can select the corresponding resolution according to the requirement of the user. For example, the electronic device may set the resolution of the image at the time of taking a picture to 2560 × 1080 in response to the user selecting an option of 2560 × 1080 resolution. The electronic device may display a preview interface for taking a picture, such as the user interface described in fig. 11, in response to the user selecting the option with a resolution of 2560 x 1080.

The method for taking a picture by the electronic device may specifically refer to a method for taking a video by the electronic device.
