[0065] To make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without any creative work fall within the protection scope of the present disclosure. In the following description, some specific embodiments are only for the purpose of description, and should not be understood as any limitation on the present disclosure, but only as examples of the embodiments of the present disclosure. When it is possible to cause confusion to the understanding of the present disclosure, the conventional structures or configurations will be omitted. It should be noted that the shapes and sizes of the components in the drawings do not reflect the true size and ratio, but only illustrate the content of the embodiments of the present disclosure.

[0066] Unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood as the general meaning understood by a person of ordinary skill in the art. The “first”, “second” and similar words used in the embodiments of the present disclosure do not represent any order, number or importance, but are only used to distinguish different components.

[0067] With the development of display technology, the size of liquid crystal display panels is also getting larger and larger. Since the light output by the liquid crystal molecules in the liquid crystal display panel already has a specific directional characteristic, when the best display effect is achieved at the front viewing angle, the picture distortion seen in the side viewing direction will also change as the side viewing angle increases, thereby causing a large viewing angle deviation between the side viewing angle and the front viewing angle. For example, there is a picture whitening problem at the side viewing angle, especially in MVA panels, therefore, it is necessary to improve the display effect of the display panel.

[0068] In view of this, the present disclosure provides an image compensation device, comprising: a data receiving circuit configured to receive to-be-processed image data, wherein the to-be-processed image data comprises a plurality of pixels, each of the plurality of pixels having a corresponding first to-be-processed pixel value; a viewing angle compensation value determining circuit configured to determine a main viewing angle compensation value and an auxiliary viewing angle compensation value corresponding to each of the target pixels according to the first to-be-processed pixel value of at least one target pixel corresponding to a predetermined region in a display region in the plurality of pixels, wherein the auxiliary viewing angle compensation value is used to assist the main viewing angle compensation value to compensate for the viewing angle deviation of the predetermined region; and a viewing angle compensation value processing circuit configured to process the first to-be-processed pixel value of the target pixel based on the main viewing angle compensation value and the auxiliary viewing angle compensation value to obtain a target pixel value of the target pixel, and obtain target image data based on the target pixel value.

[0069] It should be noted that the serial numbers of the various operations in the following steps are only used to represent the operations for description, and should not be regarded as representing the execution sequence of the various operations. The steps do not need to be executed in the order shown, unless explicitly indicated.

[0070] Figure 1 A structural schematic diagram of an image compensation device according to an embodiment of the present disclosure is shown.

[0071] As shown in Figure 1 The image compensation device 100 can include a data receiving circuit 110, a viewing angle compensation value determining circuit 120, and a viewing angle compensation value processing circuit 130.

[0072] The data receiving circuit 110 can be configured to receive to-be-processed image data. The to-be-processed image data comprises a plurality of pixels, each of the plurality of pixels having a corresponding first to-be-processed pixel value.

[0073] According to an embodiment of the present disclosure, the to-be-processed image data can be image data stored in a storage device in advance. The image compensation device can be connected with the storage device, so that the image compensation device receives the to-be-processed image data stored in the storage device.

[0074] According to an embodiment of the present disclosure, the to-be-processed image data can be to-be-processed image data about a person, to-be-processed image data about a landscape, or to-be-processed image data about an object. It can be understood that the embodiments of the present disclosure are not limited thereto.

[0075] According to an embodiment of the present disclosure, the first to-be-processed pixel value can be a value related to the display brightness of the target pixel, or a value related to the display color of the target pixel.

[0076] The view angle compensation value determination circuit 120 can be configured to determine the main view angle compensation value and the auxiliary view angle compensation value corresponding to each of the target pixels according to the first to-be-processed pixel value of at least one target pixel in the plurality of pixels corresponding to the predetermined region in the display region. The auxiliary view angle compensation value is used to assist the main view angle compensation value to compensate for the view angle deviation of the predetermined region.

[0077] According to an embodiment of the present disclosure, the display region can be a region in the display panel for displaying a picture. The predetermined region can be a region that needs to be processed in the to-be-processed image data. The pixels in the predetermined region are target pixels.

[0078] For example, the predetermined region can be the entire display region, or can be a partial region in the display region.

[0079] For example, the partial region can be determined according to the first to-be-processed pixel value of the plurality of pixels in the to-be-processed image data.

[0080] For example, in a case where the first to-be-processed pixel value is related to the display brightness of the target pixel, the predetermined region related to the brightness can be determined according to the first to-be-processed pixel value. In a case where the first to-be-processed pixel value is related to the display color of the target pixel, the predetermined region related to the color can be determined according to the first to-be-processed pixel value.

[0081] According to an embodiment of the present disclosure, the main view angle compensation value can be a value for adjusting the view angle deviation of the predetermined region, so as to reduce the view angle deviation of the to-be-processed image data in the predetermined region. The auxiliary view angle compensation value can be a value for further adjusting the view angle deviation of the predetermined region, so as to further reduce the view angle deviation of the to-be-processed image data in the predetermined region.

[0082] The view angle compensation value processing circuit 130 can be configured to process the first to-be-processed pixel value of the target pixel based on the main view angle compensation value and the auxiliary view angle compensation value, to obtain a target pixel value of the target pixel, and obtain the target image data based on the target pixel value.

[0083] According to an embodiment of the present disclosure, the first to-be-processed pixel value of the target pixel can be processed according to the main view angle compensation value and the auxiliary view angle compensation value.

[0084] For example, the first to-be-processed pixel value of the at least one target pixel can be increased or decreased according to the main view angle compensation value and the auxiliary view angle compensation value to obtain the target pixel value, or the first to-be-processed pixel value of the at least one target pixel can be calculated according to the main view angle compensation value and the auxiliary view angle compensation value to obtain a magnification multiple or a reduction multiple. The first to-be-processed pixel value of the at least one target pixel is processed according to the magnification multiple or the reduction multiple to obtain the target pixel value of the target pixel. It can be understood that the embodiments of the present disclosure are not limited thereto.

[0085] According to an embodiment of the present disclosure, a target image data is obtained by replacing a first pixel value in the image data to be processed with a target pixel value, and display is performed according to the target image data.

[0086] In the process of displaying an image, a liquid crystal display panel is prone to have a viewing angle deviation due to different viewing angles, thereby reducing the display effect. According to the technical solution of an embodiment of the present disclosure, a main viewing angle compensation value and an auxiliary viewing angle compensation value corresponding to a target pixel in a predetermined region of a display region can be determined according to a first pixel value to be processed of the target pixel. The main viewing angle compensation value is used to adjust the viewing angle deviation of the predetermined region, and the auxiliary viewing angle compensation value is used to assist the main viewing angle compensation value in adjusting the viewing angle deviation of the predetermined region, thereby reducing the viewing angle deviation of the predetermined region and improving the display effect of the liquid crystal display panel.

[0087] For example, any of the data receiving circuit 110, the viewing angle compensation value determining circuit 120, and the viewing angle compensation value processing circuit 130 can be combined in one module, or any of the modules can be split into multiple modules. Alternatively, at least part of the function of one or more of the modules can be combined with at least part of the function of the other modules and implemented in one module. According to an embodiment of the present disclosure, at least one of the data receiving circuit 110, the viewing angle compensation value determining circuit 120, and the viewing angle compensation value processing circuit 130 can be at least partially implemented as a hardware circuit, such as a field programmable gate array (FPGA), a programmable logic array (PLA), a system on chip, a system on board, a system on package, an application specific integrated circuit (ASIC), or any other reasonable manner of integrating or packaging a circuit, etc. hardware or firmware, or any one of software, hardware, and firmware or a suitable combination of any of them. Alternatively, at least one of the data receiving circuit 110, the viewing angle compensation value determining circuit 120, and the viewing angle compensation value processing circuit 130 can be at least partially implemented as a computer program module that can perform corresponding functions when the computer program module is run.

[0088] According to an embodiment of the present disclosure, the auxiliary viewing angle compensation value can include an edge compensation gain value and a first color compensation gain value.

[0089] The viewing angle compensation value processing circuit can also be configured to obtain a fusion compensation gain value of the target pixel based on the edge compensation gain value and the first color compensation gain value corresponding to the target pixel.

[0090] The main viewing angle compensation value is processed based on the fusion compensation gain value corresponding to the target pixel to determine an intermediate viewing angle compensation value corresponding to the target pixel.

[0091] The first to-be-processed pixel value of the target pixel is processed based on the intermediate view angle compensation value, the edge compensation gain value and the first color compensation gain value to obtain a target pixel value of the target pixel.

[0092] According to an embodiment of the present disclosure, the edge compensation gain value can be a value for compensating for the edges of objects, buildings, figures and the like in the to-be-processed image data, so as to eliminate the jaggy and grainy feeling of the edge profile in the to-be-processed image data and improve the display effect.

[0093] According to an embodiment of the present disclosure, the first color compensation gain value can be a value for enhancing a specific color in the to-be-processed image data, so as to improve the color display of the predetermined area and improve the display effect. For example, it can be the color of the skin of a human body or a relatively bright color in the to-be-processed image data, such as red flowers, red walls, green grass, blue sky and the like.

[0094] According to an embodiment of the present disclosure, the edge compensation gain value and the first color compensation gain value can be multiplied to obtain a fusion compensation gain value.

[0095] According to an embodiment of the present disclosure, the intermediate view angle compensation value can be determined by increasing or decreasing the main view angle compensation value according to the fusion compensation gain value.

[0096] According to an embodiment of the present disclosure, the first to-be-processed pixel value of the target pixel can be processed based on the intermediate view angle compensation value, the edge compensation gain value and the first color compensation gain value, which can be processed according to the adjustment proportion of the intermediate view angle compensation value, the edge compensation gain value and the first color compensation gain value, to obtain the target pixel value.

[0097] According to an embodiment of the present disclosure, the main view angle compensation value is adjusted by the fusion gain compensation value, which can further reduce the grainy and jaggy feeling of the predetermined area on the basis of reducing the view angle deviation, improve the color display of the image and enhance the display effect of the image.

[0098] Figure 2 A structural schematic diagram of a view angle compensation value determination circuit according to an embodiment of the present disclosure is shown. Figure 3 A viewing angle schematic diagram of a display panel is shown.

[0099] As shown in Figure 2 The view angle compensation value determination circuit 220 can include a color compensation sub-circuit 221, a view angle compensation sub-circuit 222 and an edge compensation sub-circuit 223.

[0100] As shown in Figure 3As shown, in the viewing schematic 310 of the display panel, a first polar plate 311, a second polar plate 312, liquid crystal molecules 313, a first viewing angle 314, a second viewing angle 315, and a third viewing angle 316 are included. In the display schematic 320, a first picture 321 corresponding to the first viewing angle 314, a second picture 322 corresponding to the second viewing angle 315, and a third picture 323 corresponding to the third viewing angle 316 are included. It can be seen that the viewing angle deviation of the display area is large at different viewing angles, and thus the pictures viewed at different viewing angles are different.

[0101] The following describes Figure 2 The color compensation sub-circuit 221 in the color compensation circuit 220.

[0102] According to an embodiment of the present disclosure, the auxiliary viewing angle compensation value can include a second color compensation gain value. The second color compensation gain value can be the same as the first color compensation gain value, or can be different from the first color compensation gain value.

[0103] For example, in a case where the second color compensation gain value is used alone to compensate for the viewing angle deviation of the predetermined area by the auxiliary main viewing angle compensation value, the second color compensation gain value can be different from the first color compensation gain value. In a case where the second color compensation value is used to compensate for the viewing angle deviation of the predetermined area by the auxiliary main viewing angle compensation value after being fused with the edge compensation gain value, the second color compensation gain value can be the same as the first color compensation gain value.

[0104] According to an embodiment of the present disclosure, the color compensation sub-circuit 221 can be configured to perform color space conversion on the first to-be-processed pixel value of the target pixel to obtain a second to-be-processed pixel value of the target pixel.

[0105] According to the second to-be-processed pixel value of the target pixel, a second color compensation gain value corresponding to the target pixel is determined.

[0106] According to an embodiment of the present disclosure, the color space of the first to-be-processed pixel value can be a Red Green Blue (RGB) color space. The RGB color space is intuitive and easy to understand, but the components of the three channels in the RGB color space are highly correlated, that is, if a certain component of a color changes to a certain extent, the color is likely to change. Therefore, in order to better enhance the color of the to-be-processed image data and reduce the color deviation problem, the first to-be-processed pixel value is converted in color space to obtain a second to-be-processed pixel value of the target pixel, and the color space of the second to-be-processed pixel value can be a Hue Saturation Value (HSV) color space.

[0107] According to an embodiment of the present disclosure, the second color compensation gain value corresponding to the target pixel can be determined according to the size of the second to-be-processed pixel value of the target pixel.

[0108] According to an embodiment of the present disclosure, since the second to-be-processed pixel value is color space converted, the second color compensation value determined according to the second to-be-processed pixel value can reduce the color deviation problem caused by component color change.

[0109] According to an embodiment of the present disclosure, the color compensation sub-circuit 321 can be further configured to determine the second color compensation gain value corresponding to the target pixel according to the second to-be-processed pixel value of the target pixel and the color compensation gain value relationship set.

[0110] The color compensation gain value relationship set includes at least one color compensation gain value relationship, and the color compensation gain value relationship represents the relationship between the first candidate pixel value and the candidate color compensation gain value, and the color space of the first candidate pixel value is consistent with the second to-be-processed pixel value.

[0111] According to an embodiment of the present disclosure, the color compensation gain value relationship set can be stored in a color compensation gain value lookup table. The same first candidate pixel value as the second to-be-processed pixel value can be determined from the color compensation gain value relationship set, so as to determine the candidate color compensation gain value according to the first candidate pixel value and the color compensation gain value relationship corresponding to the first candidate pixel value, and obtain the second color compensation gain value.

[0112] According to an embodiment of the present disclosure, by pre-setting the color compensation gain value relationship set of the first candidate pixel value and the candidate color compensation gain value, the second color compensation gain value can be quickly determined, and the processing speed of the to-be-processed image data can be improved.

[0113] According to an embodiment of the present disclosure, the color compensation sub-circuit 321 can be further configured to determine the first matching pixel value from the color compensation gain value relationship set. The first matching pixel value represents the first candidate pixel value matched with the second to-be-processed pixel value.

[0114] The candidate color compensation gain value corresponding to the first matching pixel value is determined as the second color compensation gain value corresponding to the target pixel.

[0115] According to an embodiment of the present disclosure, the first matching pixel value can be the first candidate pixel value determined according to the second to-be-processed pixel value. According to the color compensation gain value relationship of the first candidate pixel value, the candidate color compensation gain value corresponding to the first candidate pixel value can be determined.

[0116] The candidate color compensation gain value can be determined as the candidate color compensation gain value corresponding to the target pixel, so as to determine the second color compensation gain value corresponding to the target pixel from the candidate color compensation gain value.

[0117] According to an embodiment of the present disclosure, the color compensation gain value relationship set is a relationship between the first matching pixel value and the candidate color compensation gain value, and therefore, by means of the color compensation gain value relationship set, the second color compensation gain value corresponding to the target pixel can be determined, so that the target pixel can be color compensated according to the second color compensation gain value, and the color display of the image is improved.

[0118] According to an embodiment of the present disclosure, the second to-be-processed pixel value includes a to-be-processed hue value, a to-be-processed saturation value and a to-be-processed color brightness intensity value, and the second color compensation gain value includes a to-be-processed hue compensation gain value corresponding to the to-be-processed hue value, a to-be-processed saturation compensation gain value corresponding to the to-be-processed saturation value and a to-be-processed color brightness intensity compensation gain value corresponding to the to-be-processed color brightness intensity value.

[0119] The first candidate pixel value includes a candidate hue value, a candidate saturation value and a candidate color brightness intensity value, and the candidate color compensation gain value includes a candidate hue compensation gain value corresponding to the candidate hue value, a candidate saturation compensation gain value corresponding to the candidate saturation value and a candidate color brightness intensity compensation gain value corresponding to the candidate color brightness intensity value.

[0120] The color compensation gain value relationship set includes a hue compensation gain value relationship set, a saturation compensation gain value relationship set and a color brightness intensity compensation gain value relationship set.

[0121] The color compensation sub-circuit 221 can be further configured to determine, according to the hue compensation gain value relationship set and the to-be-processed hue value of the target pixel, a hue compensation gain value corresponding to the target pixel.

[0122] According to the saturation compensation gain value relationship set and the to-be-processed saturation value of the target pixel, a saturation compensation gain value corresponding to the target pixel is determined.

[0123] According to the color brightness intensity compensation gain value relationship set and the to-be-processed color brightness intensity value of the target pixel, a color brightness intensity compensation gain value corresponding to the target pixel is determined.

[0124] According to an embodiment of the present disclosure, the second to-be-processed pixel value includes three components in a color space. Therefore, the second to-be-processed pixel value can include a to-be-processed hue value on a hue component, a to-be-processed saturation value on a saturation component and a to-be-processed color brightness intensity value on a color brightness intensity component. Correspondingly, the second color compensation gain value includes a to-be-processed hue compensation gain value corresponding to the to-be-processed hue value on the hue component, a to-be-processed saturation compensation gain value corresponding to the to-be-processed saturation value on the saturation component and a to-be-processed color brightness intensity compensation gain value corresponding to the to-be-processed color brightness intensity value on the color brightness intensity component.

The candidate color compensation gain value includes a candidate hue compensation gain value corresponding to the candidate hue value on the hue component, a candidate saturation compensation gain value corresponding to the candidate saturation value on the saturation component, and a candidate color brightness intensity compensation gain value corresponding to the candidate color brightness intensity value on the color brightness intensity component.

[0126] The color compensation gain value relationship set can include a hue compensation gain value relationship set on a hue component, a saturation compensation gain value relationship set on a saturation component, and a color brightness intensity compensation gain value relationship set on a color brightness intensity component.

[0127] According to an embodiment of the present disclosure, a to-be-processed hue value of a target pixel can be determined from the hue compensation gain value relationship set to correspond to the target pixel. A candidate hue compensation gain value corresponding to the target pixel is determined from the candidate hue value. Then, a hue compensation gain value corresponding to the target pixel is determined according to the candidate hue compensation gain value.

[0128] According to an embodiment of the present disclosure, a to-be-processed saturation value of a target pixel can be determined from the saturation compensation gain value relationship set to correspond to the target pixel. A candidate saturation compensation gain value corresponding to the target pixel is determined from the candidate saturation value. Then, a saturation compensation gain value corresponding to the target pixel is determined according to the candidate saturation compensation gain value.

[0129] According to an embodiment of the present disclosure, a to-be-processed color brightness intensity value of a target pixel can be determined from the color brightness intensity compensation gain value relationship set to correspond to the target pixel.

[0131] Next, the present disclosure will be described in detail with reference to the accompanying drawings. Figure 2To describe in detail Figure 2 The viewpoint compensation sub-circuit 222 is configured to: determine the subject viewpoint compensation value corresponding to the target pixel based on the viewpoint compensation value relationship set and the first pixel value to be processed of the target pixel.

[0132] The viewpoint compensation value relationship set includes at least one viewpoint compensation value relationship, which represents the relationship between the second candidate pixel value and the candidate viewpoint compensation value. The color space of the second candidate pixel value is consistent with that of the first pixel value to be processed.

[0133] According to embodiments of this disclosure, the viewpoint compensation value relationship set can be pre-stored in a viewpoint compensation value lookup table. The viewpoint compensation value lookup table can be represented by a graph.

[0134] Figure 4 A schematic diagram of a set of perspective compensation relationships according to an embodiment of this disclosure is shown.

[0135] like Figure 4 As shown, the horizontal axis represents the second candidate pixel value, and the vertical axis represents the candidate viewpoint compensation value. Each second candidate pixel value can correspond to two candidate viewpoint compensation values. Relative to the same candidate pixel value, the first curve 410 represents a larger candidate viewpoint compensation value, and the second curve 420 represents a smaller candidate viewpoint compensation value.

[0136] Figure 5 A schematic diagram illustrating the determination of the subject's perspective compensation value according to an embodiment of the present disclosure is shown.

[0137] like Figure 5 As shown, each square represents a pixel in the image data to be processed. It's important to understand that the number of pixels in the diagram is merely an example and does not represent the actual number of pixels in the image data. Two pixels can be grouped together. For example... Figure 5 As shown, the first group of target pixels 510 with a darker color can represent the subject's viewing angle compensation value determined according to the second curve in the viewing angle compensation relationship set, and the second group of target pixels 520 with a lighter color can represent the subject's viewing angle compensation value determined according to the first curve in the viewing angle compensation relationship set. This allows for processing of the overall brightness effect of the image data to be processed, rather than randomly enhancing or weakening the brightness of pixels in a specific area, resulting in a more uniform brightness adjustment and reducing viewing angle deviation while ensuring the display effect of the image data to be processed.

[0138] According to embodiments of this disclosure, the relationship between the first curve, the second curve, and the second candidate pixel value is shown in the following formula (1):

[0139]

[0140] wherein gray represents the second candidate pixel value, LUT H (gray) represents the subject view angle compensation value determined according to the second candidate pixel value and the first curve, and LUT L (gray) represents the subject view angle compensation value determined according to the second candidate pixel value and the second curve.

[0141] According to an embodiment of the present disclosure, the brightness of the image data to be processed can also be adjusted according to other rules.

[0142] For example, one scheme is that four pixels in each row are taken as a group. The first pixel is determined according to the first curve, the second pixel is determined according to the second curve, the third pixel is determined according to the first curve, and the fourth pixel is determined according to the second curve. In the next row of pixels, the view angle compensation value is determined according to a curve different from that of the previous row.

[0143] For example, another scheme is that four pixels in each row are taken as a group. The first pixel is determined according to the first curve, the second pixel is determined according to the second curve, the third pixel is determined according to the second curve, and the fourth pixel is determined according to the first curve. In the next row of pixels, the view angle compensation value is determined according to a curve different from that of the previous row. It can be understood that the present disclosure is not limited thereto.

[0144] According to an embodiment of the present disclosure, the second candidate pixel value identical to the first pixel value to be processed can be determined from the set of view angle compensation value relationships, so as to determine the candidate view angle compensation value according to the second candidate pixel value and the view angle compensation value relationship corresponding to the second candidate pixel value, and obtain the subject view angle compensation value.

[0145] According to an embodiment of the present disclosure, by pre-setting the set of view angle compensation value relationships between the second candidate pixel value and the candidate view angle compensation value, the subject view angle compensation value can be quickly determined, and the processing speed of the image data to be processed is further improved.

[0146] According to an embodiment of the present disclosure, the view angle compensation sub-circuit 222 can also be configured to determine the second matching pixel value from the set of view angle compensation relationships. The second matching pixel value represents the second candidate pixel value matched with the first pixel value to be processed.

[0147] The candidate view angle compensation value corresponding to the second matching pixel value is determined as the subject view angle compensation value corresponding to the target pixel.

[0148] According to an embodiment of the present disclosure, the second matching pixel value can be determined as a second candidate pixel value same as the first to-be-processed pixel value. According to a view angle compensation value relationship of the second candidate pixel value, a candidate view angle compensation value corresponding to the second candidate pixel value can be determined. The candidate view angle compensation value can be determined as a candidate view angle compensation value corresponding to the target pixel, so as to determine the view angle compensation value corresponding to the target pixel.

[0149] According to an embodiment of the present disclosure, the first to-be-processed pixel value includes a to-be-processed red pixel value, a to-be-processed green pixel value and a to-be-processed blue pixel value. The view angle compensation value includes a to-be-processed red pixel view angle compensation value corresponding to the to-be-processed red pixel value, a to-be-processed green pixel view angle compensation value corresponding to the to-be-processed green pixel value and a to-be-processed blue pixel view angle compensation value corresponding to the to-be-processed blue pixel value.

[0150] The second candidate pixel value includes a candidate red pixel view angle value, a candidate green pixel view angle value and a candidate blue pixel view angle value. The candidate view angle compensation value includes a candidate red pixel view angle compensation value corresponding to the candidate red pixel view angle value, a candidate green pixel view angle compensation value corresponding to the candidate green pixel view angle value and a candidate blue pixel view angle compensation value corresponding to the candidate blue pixel view angle value.

[0151] The view angle compensation value relationship set includes a red pixel view angle compensation value relationship set, a green pixel view angle compensation value relationship set and a blue pixel view angle compensation value relationship set.

[0152] The view angle compensation sub-circuit 222 can be further configured to determine, according to the red pixel view angle compensation value relationship set and the to-be-processed red pixel value of the target pixel, a to-be-processed red pixel view angle compensation value corresponding to the target pixel. Determine, according to the green pixel view angle compensation value relationship set and the to-be-processed green pixel value of the target pixel, a to-be-processed green pixel view angle compensation value corresponding to the target pixel. Determine, according to the blue pixel view angle compensation value relationship set and the to-be-processed blue pixel value of the target pixel, a to-be-processed blue pixel view angle compensation value corresponding to the target pixel.

[0153] According to an embodiment of the present disclosure, the view angle compensation relationship set is a relationship between the second matching pixel value and the candidate view angle compensation value. Therefore, by the view angle compensation relationship set, the subject view angle compensation value corresponding to the target pixel can be determined, so that the target pixel can be subjected to view angle compensation according to the subject view angle compensation value, and the color deviation phenomenon in the display panel can be reduced.

[0154] Next, the operation of the edge compensation sub-circuit 223 will be described in detail. Figure 2 The edge compensation sub-circuit 223 can be configured to determine, according to the edge compensation gain value relationship set and the first to-be-processed pixel value of the target pixel, an edge compensation gain value corresponding to the target pixel.

[0155] The edge compensation gain value relationship set includes at least one edge compensation gain value relationship, and the edge compensation gain value relationship represents a relationship between a third candidate pixel value and a candidate edge compensation gain value. The third candidate pixel value is consistent with the color space of the first to-be-processed pixel value.

[0156] According to an embodiment of the present disclosure, the edge compensation gain value relationship set can be pre-stored in an edge compensation gain value lookup table. The third candidate pixel value same as the first to-be-processed pixel value can be determined from the edge compensation gain value relationship set. The candidate edge compensation gain value is determined according to the third candidate pixel value and the edge compensation gain value relationship corresponding to the third candidate pixel value, and the edge compensation gain value is obtained.

[0157] According to an embodiment of the present disclosure, the edge region of the to-be-processed image data can be detected by a Sobel algorithm, and the edge region is determined as the predetermined region in the display region.

[0158] For example, a 3*3 pixel block is determined with the target pixel as the center pixel. The coordinates of the target pixel are set as (x, y), the first direction can be the X direction, and the second direction can be the Y direction. The intensity of the target pixel along the first direction can be calculated by using the following formula (2):

[0159]

[0160] wherein G x represents the intensity of the target pixel along the first direction, and A represents the 3*3 pixel block.

[0161] The intensity of the target pixel along the second direction can be calculated by using the following formula (3):

[0162]

[0163] wherein G y represents the intensity of the target pixel along the second direction.

[0164] According to an embodiment of the present disclosure, the intensity of the target pixel can be determined according to the intensity of the target pixel along the first direction and the intensity of the target pixel along the second direction. The edge region of the target pixel can be determined according to the intensities of a plurality of target pixels.

[0165] According to an embodiment of the present disclosure, the third candidate pixel value and the candidate edge compensation gain value are pre-set, so that the edge compensation gain value can be quickly determined, and the processing speed of the to-be-processed image data is improved.

[0166] According to an embodiment of the present disclosure, the edge compensation sub-circuit 323 can be further configured to determine a third matching pixel value from the edge compensation gain value relationship set. The third matching pixel value represents a third candidate pixel value matched with the first to-be-processed pixel value.

[0167] The candidate edge compensation gain value corresponding to the third matching pixel value is determined as the edge compensation gain value corresponding to the target pixel.

[0168] According to an embodiment of the present disclosure, the operation of determining the third matching pixel value can refer to the operation of determining the second matching pixel value, which is not described herein again. The operation of determining the edge compensation gain value can refer to the operation of determining the perspective compensation value of the subject, which is not described herein again.

[0169] The edge compensation gain value relationship set includes a red pixel edge compensation gain value relationship set, a green pixel edge compensation gain value relationship set, and a blue pixel edge compensation gain value relationship set.

[0170] The edge compensation compensation sub-circuit 223 can also be configured to: determine, according to the red pixel edge compensation gain value relationship set and the to-be-processed red pixel value of the target pixel, a to-be-processed red pixel edge compensation gain value corresponding to the target pixel.

[0171] According to the green pixel edge compensation gain value relationship set and the to-be-processed green pixel value of the target pixel, a to-be-processed green pixel edge compensation gain value corresponding to the target pixel is determined.

[0172] According to the blue pixel edge compensation gain value relationship set and the to-be-processed blue pixel value of the target pixel, a to-be-processed blue pixel edge compensation gain value corresponding to the target pixel is determined.

[0173] According to an embodiment of the present disclosure, the edge compensation gain value relationship set is the relationship between the third matching pixel value and the candidate edge compensation gain value. Therefore, by means of the edge compensation gain value relationship set, the edge compensation gain value corresponding to the target pixel can be determined, so that the target pixel can perform edge compensation on the target data according to the edge compensation gain value, and reduce the sawtooth feeling and the grain feeling of the edge profile of the image in the display panel.

[0175] As Figure 6 shown, the image compensation method can include operations S610-S630.

[0176] In operation S610, to-be-processed image data is received. The to-be-processed image data includes a plurality of pixels, each of which has a corresponding first to-be-processed pixel value.

[0177] For example, operation S610 can refer to the data receiving circuit 110 of the above-mentioned embodiments, which is not described herein again.

[0178] At operation S620, the main viewing angle compensation value and the auxiliary viewing angle compensation value corresponding to each of the target pixels are determined according to the first to-be-processed pixel values of at least one target pixel corresponding to the predetermined region in the display region in the plurality of pixels. The auxiliary viewing angle compensation value is used to assist the main viewing angle compensation value to compensate the viewing angle deviation of the predetermined region.

[0179] For example, operation S620 can refer to the viewing angle compensation value determination circuit 120 of the above-described embodiments, which will not be repeated here.
