Description

Technical Field

[0001] This disclosure relates to image processing technology, and in particular to an image processing apparatus, an image processor, and an image processing method. Background Technology

[0002] In esports games, the 'field of view' displayed on the monitor directly affects a player's reaction time, decision-making, and precision of operation. A larger field of view allows players to see more game information (such as the scene or the opponent's status). However, a larger field of view also means that the features of each object are displayed on a smaller area on the screen, making it harder to see details (such as the opponent's movements). In other words, different field of view sizes have their own advantages and disadvantages for esports games, and it is difficult to cater to the different needs of players in all situations. Summary of the Invention

[0003] This disclosure relates to an image processing method, comprising: receiving an initial image via an image processor; setting a first core image and a first peripheral image based on region parameters and the initial image, wherein the region parameters are used to indicate the size of the first core image; and adjusting the sizes of the first core image and the first peripheral image respectively to generate a second core image and a second peripheral image, wherein the adjustment ratios of the first core image and the first peripheral image are different.

[0004] This disclosure also relates to an image processing apparatus, comprising a display panel and an image processor. The image processor is coupled to the display panel and is used to receive an initial image from a host device. The image processor is further used to: set a first core image and a first peripheral image based on region parameters and the initial image, wherein the region parameters indicate the size of the first core image; and adjust the sizes of the first core image and the first peripheral image respectively to generate a second core image and a second peripheral image, wherein the adjustment ratios of the first core image and the first peripheral image are different.

[0005] This disclosure also relates to an image processor for receiving an initial image from a host device. The image processor is configured to perform the following operations: setting a first core image and a first peripheral image based on region parameters and the initial image, wherein the region parameters indicate the size of the first core image; and adjusting the sizes of the first core image and the first peripheral image respectively to generate a second core image and a second peripheral image, wherein the adjustment ratios of the first core image and the first peripheral image are different.

[0006] Accordingly, by adjusting the display ratio of the core image and the peripheral image in different ways, the core image can be magnified locally, allowing players to clearly see the details of the picture. In addition, the peripheral image will not be obscured by the magnified core image, so as to take into account the different needs of magnifying features and increasing the field of view.

[0008] Several embodiments of the present invention will be disclosed below with reference to the accompanying drawings. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. Furthermore, for the sake of simplicity, some commonly used structures and components will be depicted in the drawings in a simple schematic manner.

[0009] In this document, when a component is referred to as 'connection' or 'coupled,' it may refer to 'electrical connection' or 'electrical coupling.' 'Connection' or 'coupled' may also be used to indicate that two or more components operate or interact with each other. Furthermore, although terms such as 'first,' 'second,' etc., are used herein to describe different components, these terms are only used to distinguish components or operations described using the same technical terms. Unless the context clearly indicates otherwise, these terms do not specifically refer to or imply an order or sequence, nor are they intended to limit the invention.

[0010] This disclosure relates to image scaling technology, which can be implemented by an image processing device (such as an image processor in a display) or as an image processing method within a processor. In subsequent embodiments, the features and operation of this disclosure are illustrated using a 'game screen' as an example. However, this disclosure is not limited thereto; in other embodiments, this disclosure can also be used to display audio / video streams or still images.

[0011] The circuit used in this disclosure will be described below: Figure 1A This is a schematic diagram of a display system 100 according to a partial embodiment of the present disclosure. The display system 100 includes a host device HD and a display device DP. In an embodiment, the display device DP is coupled to the host device HD to receive image data from a graphics processing unit (GPU) 230 in the host device HD. The display device DP includes an image processor 110 (e.g., a scaler) and a display panel 120. The image processor 110 is used to parse the image data and drive the display panel 120 according to the image data to display the corresponding image.

[0012] In some embodiments, the host device HD may be the host of a computer, and the display device DP is the monitor of the computer, and is coupled to the host device HD in a wired or wireless manner, but the content shown to it is not limited thereto.

[0013] In some embodiments, the host device HD further includes a central processing unit 210 and has an application program 220 installed (e.g., a program file stored in memory). The application program 220 may be a video game, a streaming program, or a video playback program. When the central processing unit 210 executes the application program 220, the central processing unit 210 generates corresponding image data through the graphics processor 230 and transmits the image data to the display device DP to display the image corresponding to the application program 220, such as a game screen.

[0014] Figure 1B This is a schematic diagram showing partial features of a display system 100 according to some embodiments of the present disclosure. Please refer to... Figure 1A and 1B The image processor 110 includes an arithmetic circuit 111 and a memory 112. The arithmetic circuit 111 is coupled to the memory 112, which stores cache data used by the image processor 110 during operation and device information of the display device DP (such as the type, aspect ratio, and resolution of the display screen 120). Specifically, when the host device HD runs the application 220, the host device HD transmits an initial image Img1A to the image processor 110, and the image processor 110 generates an output image Img2 based on the initial image Img1A. Figure 1B Some of the contents (such as adjusting image Img1B, non-linear scaling module 111A) will be described in detail in subsequent paragraphs.

[0015] The 'initial image / output image' is an image signal or image data (such as pixel values) that records a specific frame, and can correspond to a static single image or multiple dynamic images. The output image may contain the corresponding drive signal for a specific image frame, such as a drive voltage generated based on the pixel values. Since those skilled in the art can understand the meaning of image signals such as 'initial image / output image', it will not be described in detail here.

[0016] Here Figure 1A-3 For example, one implementation of the present disclosure is described below. Figure 2 This is a flowchart of an image processing method according to some embodiments of the present disclosure. Figure 3 This is a schematic diagram of the screen displayed by the image processing device, wherein the display device 300 can be implemented as... Figure 1A The display device DP is used. In this embodiment, the 'image processing device' is implemented by the display device DP, but this disclosure is not limited thereto. In other embodiments, the image processor 110 may be disposed outside the display device DP and communicateably connected to the display panel 120 via wired or wireless means. Furthermore, the operations performed by the image processor 110 (processing circuit 111) described below may also be performed by the processing circuit within the central processing unit 210 or the graphics processor 230.

[0017] In step S201, the image processor 110 receives the initial image Img1A from the graphics processor 230 of the host device HD. Figure 3 The 'initial screen 310' shown is the screen displayed on the display panel 120 when the display device 300 has not adjusted the content of the initial image Img1A (i.e., the image processor 110 has not adjusted the display mode of the initial image Img1A). In normal operation, if the user does not input the adjustment signal Sadj to activate the 'extended function', the image processor 110 will directly drive the display panel 120 according to the initial image Img1A.

[0018] To change the game's field of view, one method is to use the 'adjust display ratio' function in application 220 to adjust the display ratio of the initial image Img1A. However, since the size of the display panel 120 is fixed, it is not ideal for displaying images with other aspect ratios. For example, if the aspect ratio of the display panel 120 is '4:3', and the display ratio of the initial image Img1A is manually adjusted from the default '4:3' to '16:9', black bars will appear at the top and bottom of the screen due to the mismatch in aspect ratio. In other words, the display area of ​​the display panel 120 used to present the game screen will become smaller, making it less conducive to viewing.

[0019] On the other hand, if the image processor 110 forces a '16:9' image to fill the display area of ​​the display panel 120 (i.e., a '4:3' ratio), the shape of objects in the image will be distorted (e.g., a perfect circle becomes an ellipse). For e-sports games, object distortion will affect the user's judgment and operational precision. This disclosure, through subsequent steps S202 to S207, adjusts the image size in different ways for different local areas of the initial image Img1A / initial screen 310 to balance the 'field of view' and the 'accuracy of objects in the image'.

[0020] In step S202, when the user inputs the adjustment signal Sadj to the display device DP / 300 via an input device (such as a mouse, keyboard, or on-screen button), the image processor 110 activates the 'extended function' based on the received adjustment signal Sadj.

[0021] The purpose of the 'extended function' is to increase the field of view, therefore the display ratio of the image must be changed. In this embodiment, the aspect ratio of the display panel 120 is described as '4:3'. In other words, the ratio of the initial image Img1A to the initial screen 310 is also '4:3'.

[0022] In step S203, the image processor 110 transmits the device information signal Sed from the memory 112 to the host device HD. The device information signal Sed may be a display label parameter (e.g., Extended Display Identification Data, EDID) containing a first aspect ratio (e.g., 16:9). This first aspect ratio differs from the second aspect ratio of the display panel 120 (e.g., the size ratio of the display panel 120 is '4:3'), and the resolution corresponding to the first aspect ratio is greater than the resolution corresponding to the second aspect ratio, thus presenting a larger field of view. After receiving the device information signal Sed, the graphics processor 230 in the host device HD changes the size of the initial image Img1A according to the device information signal Sed to generate / provide an adjusted image Img1B with the first aspect ratio.

[0023] Although the adjusted image Img1B with the first aspect ratio has a large field of view, its aspect ratio does not match the display panel 120. Therefore, if the adjusted image Img1B is displayed directly, the aforementioned 'black border' problem will occur. Therefore, this disclosure modifies the image of the adjusted image Img1B in different ways to avoid the problems of 'black border' or 'object distortion'.

[0024] Specifically, in step S204, the processing circuit 111 of the image processor 110 identifies and adjusts the first core image 311 and the first peripheral image 312 in the image Img1B based on a set region parameter. For example... Figure 3 As shown, the first core image 311 includes the game character and the range of the game character's skills, which is the area that users focus on.

[0025] The 'region parameter' is used to indicate the size of the first core image 311, such as determining the radius of a circular region or the length and width of a rectangular region. Therefore, the image processor 110 can identify a core region in the adjusted image Img1B according to the region parameter, so as to set a portion of the adjusted image Img1B corresponding to the core region as the first core image 311, and set the other portions of the adjusted image Img1B as the first peripheral image 312.

[0026] In the embodiment, the first core image 311 is located in the center of the screen by default, and its vertical length is fixed. Therefore, the region parameter is only used to determine the horizontal width of the first core image 311, such as 600 pixels or 30% of the total horizontal width.

[0027] In step S205, the image processor 110 linearly enlarges the size of the first core image 311 to form a second core image. 'Linear enlargement' means that the first core image 311 is enlarged proportionally, so the outline of the object is not distorted. In other embodiments, the processing circuit 111 of the image processor 110 may also enlarge the first core image 311 into a second core image in a non-linear manner according to a set enlargement parameter (e.g., length adjusted to 110%, width maintained at 100%). The aforementioned 'region parameter' and 'enlargement parameter' can be preset in the image processor, but can also be input or adjusted by the user, for example, by inputting a setting signal Sosd (On-Screen Display, OSD) to the display device DP.

[0028] In step S206, the image processor 110 further adjusts the size of the first peripheral image 312 non-linearly to form the second peripheral image. The adjustment ratio of the first core image 311 is different from the adjustment ratio of the first peripheral image.

[0029] In step S207, the image processor 110 uses the second core image and the second peripheral image to form an output image Img2 that conforms to the second aspect ratio, and drives the display panel 120 to generate the corresponding image.

[0030] To better understand how 'Adjust Image Img1B' is adjusted to 'Output Image Img2', please refer to [link / reference]. Figure 4A The schematic diagram shown indicates that the display device 400 can be implemented as follows: Figure 1A Display device DP or Figure 3 The display device 300. Figure 4A In this image, the first core image 410A and the first peripheral image 420A are both parts of the adjustment image Img1B. At this time, because the first aspect ratio of the adjustment image Img1B does not match the second aspect ratio of the display panel, the adjustment image Img1B cannot actually fill the display area of ​​the display panel, and there will be a 'black border'.

[0031] Following the above, as in step S205, since the first core image 410A will be linearly enlarged to become the second core image 410B, which will occupy more area, the first peripheral image 420A will be resized according to the display area in the display device 400 'excluding the second core image 410B', so that the second peripheral image 420B can fill the display area 'excluding the second core image 410B'.

[0032] Therefore, since the second core image 410B is magnified linearly (or with a relatively small degree of non-linearity), objects will not be distorted, and users can correctly judge objects in the screen. On the other hand, although objects in the second peripheral image 420B may be distorted, the second peripheral image 420B is not the core area of ​​the screen, so its main purpose is to fill the display area 'excluding the second core image 410B' to improve the field of view. By adjusting the sizes of the first core image 410A and the first peripheral image 420A respectively, the needs of 'increasing the field of view' and 'maintaining the accuracy of objects in the core area' can be met simultaneously.

[0033] It should be noted that, although in the foregoing embodiment the first core image 410A is 'enlarged' to become the second core image 410B, in other embodiments the first core image may also be 'shrunken' to become the second core image, so as to modify the adjusted image into the output image.

[0034] The following will be based on Figure 1A-4B For example, this disclosure illustrates the method of image scaling, where... Figure 4BThis is a schematic diagram illustrating the sampling method of an image processing apparatus (e.g., a display device) according to some embodiments of the present disclosure. In some embodiments, the image processor 110 performs magnification and / or reduction processing via a nonlinear scaling module 111A. If 'a single image is magnified or reduced on an average basis', the image is sampled with a fixed scaling factor. For example: Figure 4B The sampling method 431 shown is used for 'average magnification', which requires sampling multiple pixel values ​​of the image. After sampling, the magnified pixel values ​​of the image can be obtained through interpolation.

[0035] Figure 4B The sampling method 432 shown is used for 'average scaling down'. Since fewer pixels are used after the image is scaled down, the sampling frequency is also lower. As mentioned earlier, average scaling down can cause 'aspect ratio mismatch', so it is not ideal.

[0036] Figure 4B The sampling method 433 shown is an illustration of the aforementioned steps S201 to S207, wherein the core region 433A (corresponding to the first core image) has a higher sampling frequency, and the peripheral region 433B (corresponding to the first peripheral image) has a lower sampling frequency. Therefore, by using different methods to reset the size of different regions, the aforementioned requirement of balancing the field of view and object accuracy can be achieved.

[0037] For ease of understanding, here we will use Figure 1A , 1B Taking 4C-4E as an example, this further illustrates the images presented by the image processing device under different processing methods. Figure 4C The image 440 displayed by the display device 400 is the result of the graphics processor 230 converting and adjusting the initial image Img1A into image Img1B according to the first aspect ratio. For example... Figure 4C As shown, because the first aspect ratio is different from the size ratio of the display device 400 (the second aspect ratio), black borders appear above and below the image screen 440.

[0038] Figure 4D Image frame 442 is adjusted to conform to the aspect ratio (second aspect ratio) of the display device 400 when image Img1B is forcibly adjusted. Figure 4D As shown, due to the scale mismatch, the shapes of objects in the 442 planes of the image frame will be distorted (e.g., Figure 4C The square in Figure 4D (It is deformed into a rectangle), so the display effect is not ideal. Figure 4E According to Figure 2The image produced by the image processing method shown above. Figure 2 The method shown involves the image processor first identifying the first core image 441A and the first peripheral image 441B from the adjusted image Img1B. Then, the image processor adjusts the sizes of the first core image 441A and the first peripheral image 441B respectively to generate... Figure 4E The second core image 443A and the second peripheral image 443B are shown.

[0039] Figure 4C The first core image 441A and the first peripheral image 441B can be equivalent to Figure 4A The first core image 410A and the first peripheral image 420A shown are, and Figure 4E The second core image 443A and the second peripheral image 443B can be equivalent to Figure 4A The second core image 410B and the second peripheral image 420B are shown. For example... Figure 4E As shown, the second core image 443A is a linearly enlarged image without distortion, and the second peripheral image 443B can fill the entire display area without producing a 'black border'.

[0040] The following will be based on Figure 1A , 1B Using examples 5 and 6, the operation of another embodiment of this disclosure will be explained. Figure 5 This is a flowchart of an image processing method according to some embodiments of the present disclosure. Figure 6 This is a schematic diagram of an image presented by an image processing apparatus (e.g., a display device DP) according to a portion of the embodiments of this disclosure. In this embodiment, a first-person shooter (FPS) game will be used as an example for explanation.

[0041] like Figure 6 As shown, in a first-person shooter game, a user can activate a scope to magnify a specific area of ​​the screen. However, in related technologies, when the scope magnifies a specific area, it obscures other surrounding images, affecting the field of view (i.e., a blind spot). This disclosure avoids this problem by changing the display size of different areas in different ways.

[0042] Please see Figure 1A , 1B In steps S501, the image processor 110 receives the initial image Img1A from the host device HD, and drives the display panel 120 to display the initial image 600 based on the initial image Img1A (e.g., ...). Figure 6 (as shown in the image).

[0043] In step S502, when the user inputs an adjustment signal Sadj to the display device DP via an input device (e.g., by selecting to enable the 'sniper scope' function using a mouse, keyboard, or on-screen button), the image processor 110 will identify the target area of ​​the initial image Img1A / initial screen 600 based on the received adjustment signal Sadj. In this embodiment, the adjustment signal Sadj includes coordinates (e.g., the position the gun is pointing at in the game), and the image processor 110 has a default range set for the target area 610 (i.e., the area that the 'sniper scope' should display). The image processor 110 can set the target area 610 in the initial image Img1A / initial screen 600 based on the default range, using the coordinates indicated by the adjustment signal Sadj as the center (e.g., by selecting to enable the 'sniper scope' function using a mouse, keyboard, or on-screen button). Figure 6 (The sniper scope range shown).

[0044] In step S503, the image processor 110 sets a portion of the target region 610 as the first core image 611 and sets the remaining portion of the target region 610 as the first peripheral image 612, based on default region parameters. In this embodiment, the region parameters can be the proportion of the first core image 611 within the target region 610.

[0045] It should be noted that the first core image 611 needs to be enlarged, but the enlarged image cannot obscure other images. Therefore, the method adopted in this disclosure is similar to the aforementioned steps S204 to S207, further dividing the target area 610 into two areas (i.e., the first core image 611 and the first peripheral image 612), and resizing them with different display ratios for different areas.

[0046] Specifically, in step S504, the image processor 110 fixes / maintains the first core image 611 and non-linearly reduces the first peripheral image 612. For ease of explanation, the reduced first peripheral image 612 and the fixed / maintained first core image 611 are referred to as the 'target image'. The extent to which the first peripheral image 612 is reduced can be determined by the user or application (e.g., the magnification of a sniper scope). In other embodiments, the image processor 110 may also linearly adjust the size of the first core image 611 to form the target image.

[0047] Next, in step S505, the image processor 110 linearly enlarges the target image to form a second core image and a second peripheral image. In other words, the enlarged target image includes the non-linearly processed second peripheral image and the linearly processed second core image. In this embodiment, the total area of ​​the final generated second core image and second peripheral image is equal to the total area of ​​the first core image 611 and the first peripheral image 612, which is the size of the target region 610. Therefore, the second core image and second peripheral image do not obscure the image surrounding the target region. In other embodiments, the image processor 110 may also non-linearly shrink or enlarge the first core image 611, not limited to linear adjustment.

[0048] In step S506, the image processor 110 uses the second core image and the second peripheral image to form an output image. Specifically, the image processor 110 can maintain the display ratio of the areas other than the target area 610 in the initial image Img1A / initial screen 600 as a background image. Then, the image processor 110 integrates the background image, the second core image, and the second peripheral image into an output image, and the size and aspect ratio of the integrated output image Img2 are still the same as those of the initial image Img1A / initial screen 600.

[0049] To facilitate understanding how the 'initial image Img1A' is adjusted to the 'output image Img2', we will use... Figures 7A-7C The diagram shown is used for illustration. Figure 7A The initial screen 710 shown can be equivalent to Figure 6 The initial frame shown is 600, and the target area 711 can be... Figure 6 Target area 610.

[0050] like Figure 7A and 7B As shown, the target area 711 is the default display range of the 'sniper scope function'. As described in step S504 above, the image processor 110 identifies the first core image 712A and the first peripheral image 712B in the target area 711.

[0051] As described in steps S504 and S505, the image processor 110 first reduces the first peripheral image 712B in a non-linear manner, so that the first core image 712A and the reduced first peripheral image 712B form the target image. Then, the image processor 110 linearly enlarges the entire target image to generate... Figure 7C The second core image 713A and the second peripheral image 713B are shown. Figure 7CAs shown, the total area of ​​the second core image 713A and the second peripheral image 713B is equal to the area of ​​the initial target region 711.

[0052] Therefore, by first non-linearly reducing the first peripheral image 712B and then uniformly linearly enlarging the target image, the requirements of 'local magnification' and 'avoiding blind spots' can be met. In other words, not only is the content of the first core image 712A magnified, but the magnified second core image 713A and second peripheral image 713B do not obscure other images outside the target area 711.

[0053] The components, method steps, or technical features in the foregoing embodiments can be combined with each other, and are not limited to the order of textual description or the order of presentation of drawings in this disclosure.

[0054] Although the present disclosure has been described above with reference to embodiments, it is not intended to limit the present disclosure. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be determined by the appended claims. Symbol Explanation
