Description

How to present a zoomed-in screen

The present invention relates to a method for enlarging a display screen, in particular to a method for enlarging a display screen through a display device.

With the development of science and technology, there are more and more types of entertainment that can be performed in human society. Among them, after the vigorous development and popularization of personal electronic devices, video games, computer games, e-sports, etc. are the largest. Economic benefits also increased. For example, there are many types of video games, such as music games, card games, shooting games, massively multiplayer online role-playing games (MMORPG), multiplayer online battle arena games (multiplayer online battle arena, MOBA), racing games, sports...

Most of the current electronic games require a display screen to display the game screen to the user in real time. Although the existing so-called gaming screens are advertised as "gaming screens", they only focus on the display panel's resolution, update rate, and hardware specifications such as the I/O interface behind the screen. However, they are rarely used by gamers. Think about what auxiliary functions the user needs to display on the screen when displaying the game screen on the screen to enhance the game experience.

Take first-person shooting (FPS) as an example, please also refer to Figure 1. The graphics of this kind of game are intended to allow the user to enter the game character and directly observe the game world from a first-person perspective. Usually, the gun currently used by the game character can be seen in the lower right corner of the screen, and the pattern in the center of the screen (usually the center) is the position where the game character uses the gun to aim. Some types of firearms may have scopes, such as rifles, rifles, sniper rifles, etc. When using these firearms, you can use the scope function by triggering the button (for example, the right mouse button). When using the scope function, the game screen is enlarged by simulating a scope with magnification, which means that the target (such as an enemy player) to be aimed at is also enlarged in the area displayed on the screen. Due to the enlargement of the target area, the range of the hit box is increased, and the probability of the mission is greatly increased. However, the magnification of the scope is usually set to a fixed size, and depending on the type and grade of the gun, the magnification of the scope is also different, so the magnification may be only a small magnification due to the lower grade of the gun. What's more, when equipped with a gun without a scope, such as a pistol, the user may be at a disadvantage in battle because the user cannot use the scope to zoom the picture. In the past, users could install additional software or special software to enable additional game assistance functions such as screen magnification. However, this may be discovered by game operators through software detection and judged as unfair behaviors, which may be subject to game operators’ actions. penalty.

In general, depending on the types of games, users may need auxiliary functions on the screen display to satisfy their gaming experience. However, due to restrictions on game rules and modes, users cannot do so. Therefore, a method for enlarging the display screen without using software is required to meet the needs of users.

In view of the above, the present invention provides a method for enlarging a display screen to meet the above requirements. After the screen information is transmitted to the display device, the display device processes the screen information to enlarge the display screen according to different requirements.

An embodiment of the present invention provides a method for presenting a magnified image, which is suitable for a display device including a display panel. The method includes: receiving a parent image information by the display device; using the display device to display information on the display panel according to a display command Select a display area on the top; use the display device to select an image capture range on the display panel according to an image capture command, wherein the image capture range includes a part of the parent picture information; use the display device to select an image capture range within the image capture range The part of the parent picture information is enlarged as a child picture information; and a composite picture is displayed on the display panel by the display device, wherein the composite picture includes the child picture information and at least part of the parent picture information, and wherein The sub-picture information is located in the display area.

The above description of the present disclosure and the following description of the embodiments are used to demonstrate and explain the spirit and principle of the present invention, and provide further explanation of the scope of the patent application of the present invention.

The detailed features and advantages of the present invention are described in detail below in the embodiments, and the content is sufficient to enable any person skilled in the relevant art to understand the technical content of the present invention and implement it accordingly, and according to the content disclosed in this specification, the scope of the patent application and the drawings , any person skilled in the related art can easily understand the related objects and advantages of the present invention. The following examples further illustrate the viewpoints of the present invention in detail, but do not limit the scope of the present invention in any viewpoint.

Please refer to Figure 2. FIG. 2 is a flowchart of a method for enlarging a display screen according to the first embodiment of the present invention. The method for enlarging a display screen according to an embodiment of the present invention, without changing the data of the received screen information itself, amplifies the received signal through the scaler IC of the display device, and simultaneously displays the enlarged image on the display panel. Picture information and at least part of the original picture information, so as to achieve the effect of enlarging the picture.

The flow of the method for enlarging a display image according to the first embodiment of the present invention firstly refers to step S1, where the display device receives a parent image information. Regarding step S1, reference may be made to FIG. 1 at the same time. The picture 10 of FIG. 1 is defined herein as parent picture information 10 . In practice, the display device includes a display panel, and the display device can be electrically connected to the electronic device, the electronic device generates the parent image information 10 through calculation and then transmits it to the display device, and the display device displays the parent image information 10 on the display panel. superior. The electronic device can be, for example, a desktop computer host, a video game instrument, and the like. The electronic device can also be, for example, a mobile electronic device, a notebook computer, etc. In this case, the display device can be regarded as an additional external screen connected to the electronic device. The present invention does not limit the implementation of the electronic device. In the first embodiment of the present invention, the parent image information 10 may be display image information generated by the game program after operation by the graphics processor. The screen of the first-person shooter game is displayed on the display panel of FIG. 1 . Examples of the relationship between other game types and other implementation aspects of the present invention will be described in detail later.

Referring to step S2, the display device selects a display area on the display panel according to a display command. As shown in FIG. 3A , in the method for presenting an enlarged image according to the first embodiment of the present invention, a display area DA can be selected in step S2 , and the display area DA is an area where the enlarged image is displayed on the display panel. The display command can be generated by triggering a physical key on the display device, and the display command is used to control the position (eg, determined by coordinates), size, shape, etc. of the display area on the display panel. In practice, taking the shooting game of FIG. 3A as an example, the display area DA may be a circular area, which is arranged on the upper left side of the center of the screen, so as not to obstruct the center of the screen. In addition, the present invention does not limit the position, size and shape of the display area DA, which may have different parameters according to different situations.

Referring to step S3 , the display device selects an image capturing area on the display panel according to an image capturing command, wherein the image capturing area includes a part of the mother picture information 10 . Please also refer to Figure 3B. The image capture command, like the display command, can be generated by triggering a physical button on the display device, and the image capture command is used to control the position (for example, determined by coordinates), size, shape etc. In addition, since the parent picture information 10 is imaged, the position, size, and shape of the image capturing range CR are basically highly correlated with the parent picture information 10 . In practice, taking the shooting game shown in FIG. 3B as an example, if the user needs to enlarge the reticle at the center of the screen and the periphery of the reticle, the image capturing range CR can be a circle formed by expanding outward for a certain distance at the center of the screen panel. range, wherein the acquisition range CR includes the crosshair of the parent picture information 10 and its surrounding pictures. In addition, the present invention does not limit the position, size and shape of the imaging range CR, which may have different parameters according to different situations.

Please refer to step S4, and the display device enlarges the part of the main picture information 10 in the image capturing range CR to use it as a sub picture information. Specifically, the display device can select a magnification according to a magnification command, and then use the magnification to enlarge the part of the parent picture information 10 within the image capturing range CR as the sub picture information. The magnification command can be generated after being triggered by a physical button on the display device. In practice, the display device may have a scaling chip (scaler IC) for signal scaling, and the scaling chip can perform signal scaling in step S4. The present invention does not limit the size of the magnification, and in practice, different magnifications can be used according to requirements.

In addition, since the sub-picture information is obtained by enlarging the part of the parent-picture information 10, but it is enlarged under the condition that the original resolution remains unchanged, relatively speaking, the graininess of the picture will also increase. Therefore, after the sub-picture information is generated, the display device can perform image compensation on the sub-picture information to make the lines smoother. In practice, the image enhancement function of the scaling chip's own hardware can be used to interpolate several pixels in the enlarged sub-screen information to reduce the graininess and make the screen smooth and natural.

In addition, after the sub-screen information is generated, the on-screen display (OSD) function suitable for adaptive adjustment in the first embodiment of the present invention can be used to display the device on the sub-screen according to user needs, game types, etc. At least one pattern is generated in the picture information. Alternatively, when the display device enlarges the part of the parent picture information 10 in the image capturing range CR as the sub-picture information, at least one pattern is generated so that the sub-picture information includes at least the pattern. For example, usually in a shooting game, when a sniper rifle is selected as the currently used weapon, the crosshair will not appear on the game screen by default, and the crosshair will only be displayed when the sniper mode is turned on. At this time, the pattern of the sub-screen information can be a crosshair, so that when the user does not turn on the sniper mode, there is still a crosshair for aiming on the screen. In addition, an outer frame pattern of the scope can be generated in the sub-screen information, which not only pursues the authenticity and immersion of the game, but also can distinguish the sub-screen information in the display screen. FIG. 3C shows the outer frame pattern of the scope in which the sub-picture information 11 includes a black frame in a simple manner.

In addition, after the sub-picture information is generated, the first embodiment of the present invention can use the display device to perform filter processing on the sub-picture information according to a filter command. The OSD function of the conventional display device may have a blue light filter function, so that the displayed screen image can filter out a certain percentage of blue light. The first embodiment of the present invention can use a display device with more filter functions to perform filter processing on the sub-picture information, so that the sub-picture information can present a picture with a night vision goggle feel, an infrared thermal imager-like picture... Wait. The filter command can be generated after being triggered by a physical button on the display device.

Referring to step S5, the display device displays a composite picture on the display panel, wherein the composite picture includes the information of the sub-picture and at least part of the information of the mother picture, and the information of the sub-picture is located in the display area. Please also refer to Figure 3C. In practice, step S5 can be achieved by using the picture in picture function of the zoom chip. After the part of the parent picture information 10 is enlarged into the child picture information 11, the display device simultaneously displays the child picture information on the display panel. 11 and part of the parent picture information 10'. As shown in FIG. 3C , the composite picture includes sub-picture information 11 and part of the parent-picture information 10 ′, wherein the sub-picture information 11 is located in the display area DA, and the part of the parent-picture information 10 ′ is the original parent-picture information 10 minus the range of the display area DA The local parent picture information in the . The composite picture not only includes at least part of the original picture (parent picture information), but also includes the enlarged and displayed partial picture (sub picture information). In other words, the sub-picture information 11 replaces the local parent-picture information within the display area DA of the original parent-picture information 10 .

In the method for presenting an enlarged image according to the first embodiment of the present invention, after steps S1 to S4, in practice, the synthesized image can be displayed through a trigger signal. The displaying of the composite picture on the display panel by the display device in step S5 includes: displaying the composite picture on the display panel by the display device according to a trigger signal. The trigger signal can be generated after being triggered by a physical button on the display device, or can be generated by an electronic device outside the display device and sent to the display device. For example, after triggering a hot key of an input device (such as a keyboard) electrically connected to the electronic device, the trigger signal can be transmitted to the display device through the electronic device. In addition, the trigger signal can be biological data, such as gestures, body movements, or audio containing keywords, etc., and the input device can generate the trigger command when it is recognized and compared to the biological data and conforms to the preset command. The present invention does not limit the way of generating the trigger signal.

In the method for presenting an enlarged picture according to the first embodiment of the present invention, after the display device receives the parent picture information, a part of the parent picture information is enlarged by the selected display area and image capturing range of the display device to generate the child picture information, and the information is displayed on the display panel. A composite picture including the information of the sub-picture and at least part of the information of the parent picture is displayed thereon. The method can be adjusted on the display device according to various requirements without changing the source data of the parent picture information, and simultaneously display at least part of the parent picture information and the child picture information. Even if a pistol without a scope function is used in the current game, the display device can still present an enlarged image with a scope function by implementing the first embodiment of the present invention.

Please refer to FIG. 4 , FIG. 5A and FIG. 5B . Compared with the first embodiment, the second embodiment of the present invention provides a method for presenting a zoomed-in picture by simultaneously displaying two sub-picture information. As shown in the flowchart of FIG. 4 , step S1 is the same as step S1 of the first embodiment, and steps S2 ′ to S4 ′ and steps S2 ″ to S4 ″ are also substantially similar to steps S2 to S4 of the first embodiment, However, the first display area DA1 , the second display area DA2 , the first imaging range CR1 and the second imaging range CR2 are additionally defined according to the two sub-picture information (the first sub-picture information 21 and the second sub-picture 22 ). The second embodiment of defining the two sub-picture information 21 and 22 takes a racing game as an example. Since the rearview mirror can reflect the distance of the opponent's vehicle behind relative to oneself, thereby changing the driving strategy of the player, the left and right rearview mirrors can be adjusted accordingly. The first and second imaging ranges CR1 and CR2 are obtained, and the display areas DA1 and DA2 can be set by expanding outward from the positions covering the imaging ranges CR1 and CR2 of the original rearview mirror to present the enlarged sub-picture information 21 and 22 . At this time, the composite picture in step 5' of the second embodiment of the present invention includes the first sub-picture information 21, the second sub-picture information 22 and part of the parent picture information 20'. Note that the black boxes around the two sub-picture information 21 and 22 in FIG. 5B only represent the range of the display areas DA1 and DA2, and the actual composite picture may not include the black boxes. Practically applicable, the composite picture of the method for presenting the enlarged picture of the present invention may include a plurality of sub-picture information, which depends on the user's requirement and the hardware performance of the display device, and the present invention does not limit the quantity of the sub-picture information.

Please refer to FIG. 6A and FIG. 6B . In the method of presenting an enlarged picture of the present invention, in addition to enlarging a part of the parent picture information as the child picture information, if you do not want to cover the original parent picture information when presenting the child picture information, the composite picture is displayed on the display panel by the display device. , you can use the display device to reduce the parent picture information. The method for presenting an enlarged image in the third embodiment of the present invention is similar to the steps in the first/second embodiment, except that when the composite image is displayed on the display panel by the display device, the information of the parent image is reduced by the display device. For ease of understanding, FIG. 6A also shows the image capturing ranges CR3 and CR4 in the parent picture information 30 . The composite picture in FIG. 6B includes the reduced parent picture information 30' and two sub picture information 31 and 32 located in the two display areas DA3 and DA4. Preferably, the sub-picture information 31, 32 in the composite picture and the reduced parent-picture information 30' can be displayed side by side. Taking a massively multiplayer online game as an example, by reducing the size of the main screen information 30, the sub-screen information 31 and 32 can prevent the partial screen of the main screen information 30 from obscuring the partial screen, and the partial screen may be the same important during the game but does not need to be enlarged. Information. In addition, if the parent picture information 30 is proportionally reduced, as shown in FIG. 6B, an "inverse L"-shaped space may be formed on the display panel (the picture that can be displayed on the screen panel minus the reduced parent picture information), At least one sub-picture information can be placed in this space, and the composite picture at this time includes the sub-picture information, the reduced parent picture information and the space. Generally speaking, when the size, resolution, etc. of the display image are not changed, the composite image shown in FIG. 6B is equal to the size of the original mother image information 30 . The present invention does not limit the reduction ratio of the parent screen information and the size and shape of the space formed on the display screen after the reduction. For the composite picture shown in Fig. 6B, the reduced parent picture information 30' and the child picture information 31 and 32 are side by side, and the remaining space is the dark gray area at the bottom of the picture.
