Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The following describes in detail an image processing method, an image processing apparatus, and an electronic device provided in the embodiments of the present application with reference to the accompanying drawings.
Referring to fig. 1, a schematic diagram illustrating steps of an image processing method provided in an embodiment of the present application includes:
The Depth of Field (DOF) is an imaging range in which a sharp image can be obtained at the front edge of a camera lens or other imaging devices, and is a measured distance range between the front and rear of a subject, that is, a distance between a sharp image appearing in a range between the front and rear of a focal point after the completion of focusing by a camera, and is an important factor affecting the Depth of Field.
At present, a camera of an electronic device is limited by hardware such as an aperture and a lens, and cannot meet the requirement that elements corresponding to all depth ranges are imaged clearly in one image obtained by one-time shooting, for example, when clear close-range characters are shot, a background is blurred.
In the embodiment of the present application, different depth-of-field ranges may correspond to different distant and close objects in a shooting scene, for example, referring to fig. 2, which shows a schematic diagram of a shooting image provided in the embodiment of the present application, in a shooting image, the depth-of-field range may be divided into a far-field range, a middle-field range, and a near-field range, the far-field range corresponds to a distant object, the middle-field range corresponds to a moderate-distance object, and the near-field range corresponds to a near-field object, and when a user shoots, in order to achieve rich image effect, the user usually has different depth-of-field requirements, for example, referring to fig. 2, assuming that an object corresponding to the near-field range is a person, and the user wants to shoot a person image that highlights the near-field person 12, the user may focus and shoot in the near-field range to obtain a person image that is clear with the near-field person 12 and other, so that the person in the picture is highlighted. In addition, the user may also require that objects corresponding to multiple ranges in the long-range, the medium-range, and the short-range in the final captured image are imaged clearly based on higher imaging requirements.
Therefore, the camera of the electronic device can select at least one target depth of field range according to the imaging requirement by the user based on the multiple depth of field ranges which can be provided by the camera, so that the object corresponding to the target depth of field range can be imaged clearly in the final imaging. The electronic device may include a cell phone, camera, watch, aerial camera, etc.
And step 102, focusing and shooting an object corresponding to each target depth of field range respectively according to the same exposure parameters and camera postures to obtain an initial image corresponding to each target depth of field range.
In the embodiment of the application, in order to meet the requirement of a user on clear imaging of an object corresponding to a target depth of field in final imaging, initial images shot by a camera under each target depth of field range need to be acquired, and in the initial image corresponding to each target depth of field range, an object corresponding to the target depth of field range is imaged clearly.
For example, when the user requests that an object corresponding to the close view and the long view is imaged clearly, the camera focuses and shoots the long view range based on the same exposure parameters and camera posture to obtain one initial image and focuses and shoots the short view range to obtain the other initial image after the user selects the long view range and the short view range as the target depth of field range.
Specifically, when the camera shoots an initial image, the camera needs to focus and shoot an object corresponding to each target depth of field range according to the same exposure parameters and camera postures, the same exposure parameters and camera postures can ensure that edge features in the shot initial image are consistent, and the defects of gaps and the like during subsequent synthesis are avoided.
In the embodiment of the present application, the same camera pose may refer to: when the camera is used for focusing and shooting an object corresponding to each target depth of field range, the three-dimensional attitude Euclidean angles (a pitch angle, a yaw angle and a roller angle) of the camera relative to the object are the same.
Therefore, the video camera needs to have a high response speed and a short interval time when shooting different initial images to reduce the influence of the change of the camera posture.
And 103, taking an initial image corresponding to the target depth of field range as a target image under the condition that one target depth of field range is selected.
In the embodiment of the present application, if the user only selects one depth of field range as the target depth of field range, the initial image corresponding to the target depth of field range may be directly output as the target image, for example, if the user wants to capture a person image that highlights a person in a close range, the user may use the close range as the target depth of field range, and perform focusing and capturing in the close range to obtain a person image in which the person is clear and other objects as backgrounds are blurred, so that the person in the image is highlighted.
And 104, under the condition that a plurality of target depth of field ranges are selected, carrying out image fusion on the initial images corresponding to all the target depth of field ranges to obtain target images.
In the embodiment of the application, under the condition that a plurality of target depth of field ranges are selected, the camera may shoot a corresponding initial image for each target depth of field range, and the definition of the picture element corresponding to the target depth of field range in the initial image is the highest, so that a higher fusion weight may be allocated to the picture element with the highest definition in each initial image, so that after the fusion of the initial images corresponding to all the target depth of field ranges is performed, the picture element with the highest definition in each initial image may be retained in the final target image, and the purpose of clearly displaying all the picture elements corresponding to the target depth of field range in the final target image is achieved.
For example, referring to fig. 2, the depth of field range is divided into a long-range, a medium-range, and a short-range, and assuming that the user selects the short-range, the medium-range, and the long-range as the target depth of field range, the camera may take pictures for the short-range, the medium-range, and the long-range respectively according to the same exposure parameters and camera pose, to obtain three initial images shown in fig. 3, 4, and 5, where an object 12 corresponding to the short-range in the initial image shown in fig. 3 is displayed clearly, an object 11 corresponding to the medium-range in the initial image shown in fig. 4 is displayed clearly, an object 10 corresponding to the long-range in the initial image shown in fig. 5 is displayed clearly, and areas displaying clear objects in the three initial images are extracted and fused into a target image, so that both the long-range, the medium-range, and the short-range objects in the target image are. It should be noted that, after a higher fusion weight is added to a region in the initial image where a clear object is displayed, a fusion operation based on the fusion weight may be performed on the three initial images to obtain a final target image.
In practical application, a user can select at least one target depth of field range through selection operation, after selection, the camera can automatically shoot corresponding initial images according to the target depth of field range, all the initial images are automatically fused to obtain target images, the target images are provided for the user, and in the whole process, the user does not need to perform too many complicated operations.
In summary, the embodiment of the present application provides an image processing method, which selects at least one target depth of field range from a plurality of depth of field ranges; focusing and shooting an object corresponding to each target depth of field range respectively according to the same exposure parameters and camera postures to obtain an initial image corresponding to each target depth of field range; under the condition that a target depth of field range is selected, taking an initial image corresponding to the target depth of field range as a target image; the method and the device have the advantages that under the condition that the plurality of target depth of field ranges are selected, the initial images corresponding to all the target depth of field ranges are subjected to image fusion to obtain the target images, and the picture elements corresponding to all the target depth of field ranges selected by a user can be displayed clearly in the finally displayed images based on the requirement of the user on the depth of field, so that the problem that the picture elements corresponding to only one depth of field range can be displayed clearly in the prior art is solved, and the requirement that the user has high imaging quality on more picture elements in the shot images is met.

When the user uses the shooting function, the user has a picture preview requirement for the current shooting scene, namely before the user clicks a shooting button, the electronic equipment can display a preview picture of the shooting scene collected by the camera for the user to refer to. In the embodiment of the application, after the user starts the camera shooting function, the camera can focus and shoot the object corresponding to each depth of field range according to the same exposure parameters and camera posture, so that the depth of field image corresponding to each depth of field range is obtained, the image elements corresponding to the depth of field range in each depth of field image are clearly imaged, and after all the depth of field images are fused, a clear preview image which is provided by the camera and is displayed by all the image elements corresponding to the depth of field range can be obtained for the user to refer to.
In the embodiment of the application, the target area may be an area corresponding to a picture element with the maximum definition in the depth image, and in addition, the target area may be an area corresponding to a picture element with the definition greater than or equal to a preset threshold in the depth image, and the preset threshold may be set according to actual requirements.

Further, referring to fig. 7, which shows a schematic diagram of a preview image according to an embodiment of the present application, in order to significantly distinguish regions of the picture elements corresponding to different depth of field ranges in the preview picture, the regions of the picture elements corresponding to different depth of field ranges in the preview picture may display different elements, for example, a region of the object 10 corresponding to a long range is displayed with a red hue, a region of the object 11 corresponding to a middle range is displayed with a blue hue, and a region of the object 12 corresponding to a short range is displayed with a green hue.
And step 204, displaying the preview image.

The user can select the depth of field range label, and the depth of field range corresponding to the depth of field range label selected by the user is used as the target depth of field range.
Optionally, in another implementation, the depth of field range label is located in a preset area in the preview image.
Referring to fig. 8, which shows a schematic diagram of another preview image provided in the embodiment of the present application, in order to ensure cleanness and conciseness of a preview image, a depth of field range tag may be further disposed in a fixed preset area, so as to prevent the depth of field range tag from blocking important content of the image, for example, as shown in fig. 8, three depth of field range tags may be disposed in a bottom area of the image.
Optionally, in another implementation, step 205 may include:
and a substep 2052 of taking the depth of field range corresponding to the selected region as the target depth of field range according to the selection operation on at least one region in the preview image.
In the embodiment of the application, in order to ensure the simplicity of the preview image, the depth of field range corresponding to the selected area may be directly used as the target depth of field range according to the selection operation of the user on at least one area in the preview image.
For example, for an image including elements such as a portrait, a railing, a building, and a mountain, a user may sequentially click on areas of the portrait, the railing, the building, and the mountain, and use depth ranges corresponding to the areas as target depth ranges, so that the areas have a clear display effect in a final target image.
