In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0062] See also Figure 1 , Figure 1 A flow chart of an image detection method according to an embodiment of the present disclosure is shown.

[0063] like Figure 1 As shown, the method includes:

[0064] Step S11, performing pixel detection on the display data of each color channel of each pixel of the image to be detected to obtain a detection result;

[0065] Step S12, when the detection result indicates that the color channel display data of at least one color channel conforms to the corresponding preset pixel pattern, determining that the image to be detected is a target detection image.

[0066] The disclosed embodiment obtains a detection result by performing pixel detection on each color channel display data of each pixel of the image to be detected. When the detection result indicates that the color channel display data of at least one color channel conforms to the corresponding preset pixel pattern, the image to be detected is determined to be a target detection image. The pixel pattern detection of the image to be detected can be quickly realized so that the display parameters can be adjusted subsequently to improve the display accuracy.

[0067] The image detection method of the disclosed embodiment can be executed by a processing component or an electronic device such as a terminal or a server including a processing component, so as to realize pixel detection of each color channel display data of each pixel of the image to be detected, and obtain a detection result. In the case where the color channel display data of at least one color channel of the detection result indicates that it conforms to the corresponding preset pixel pattern, the image to be detected is determined to be a target detection image. In one example, the processing component includes but is not limited to a separate processor, or a discrete component, or a combination of a processor and a discrete component. The processor may include a controller having an execution instruction function in an electronic device, and the processor may be implemented in any appropriate manner, for example, by one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors or other electronic components. Inside the processor, the executable instructions may be executed by hardware circuits such as logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers.

[0068] In one example, the terminal is also called User Equipment (UE), Mobile Station (MS), Mobile Terminal (MT), etc., which is a device that provides voice and / or data connectivity to users, for example, a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: mobile phones, tablet computers, laptops, PDAs, mobile Internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control (Industrial Control), wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grid (Smart Grid), wireless terminals in transportation safety (Transportation Safety), wireless terminals in smart cities (Smart City), wireless terminals in smart homes (Smart Home), wireless terminals in Internet of Vehicles, etc.

[0069] The embodiments of the present disclosure do not limit the specific color channels of each pixel of the image to be detected. The embodiments of the present disclosure can convert the image to be detected into the required color space (Color Space). In different color spaces, color channels have different classifications, for example, RGB (red, green, blue) color space, HSV (hue, saturation, value) color space, HSL (hue, saturation, lightness / luminance) color space, YUV (Y represents brightness, UV represents chromaticity) color space, etc. For example, for the RGB color space, each pixel of the image to be detected can include a red channel R, a green channel G, and a blue channel B. Corresponding to the display panel, a pixel can include a red pixel light, a green pixel light, and a blue pixel light. The embodiments of the present disclosure will be introduced exemplarily using the RGB color space.

[0070] Exemplarily, the image to be detected in the embodiment of the present disclosure may include M×N pixels, where M and N are both integers greater than 1, wherein M represents columns and N represents rows, and each pixel of the image to be detected may include red channel display data, green channel display data, and blue channel display data. Correspondingly, the red channel display data, green channel display data, and blue channel display data of the image to be detected each include M columns and N rows.

[0071] See also Figure 2 , Figure 2 A flow chart of an image detection method according to an embodiment of the present disclosure is shown.

[0072] In a possible implementation, Figure 2 As shown, step S11 performs pixel detection on each color channel display data of each pixel of the image to be detected, which may include:

[0073] Step S111, for the color channel display data of the current color channel, dividing multiple columns of color channel display data in the target detection area of ​​the image to be detected to obtain N display blocks, each display block includes K consecutive columns of color channel display data, wherein K and N are ≥ 1 and are both integers;

[0074] Step S112, if the number of target blocks in the display block reaches P, determine that the color channel display data of the current color channel conforms to the corresponding preset pixel style, wherein the color channel display data that conforms to the preset pixel style in the target block reaches L columns, wherein L≤K, P≤N and L and P are both integers.

[0075] The disclosed embodiment divides multiple columns of color channel display data in the target detection area of ​​the image to be detected for the color channel display data of the current color channel to obtain N display blocks, each display block includes K consecutive columns of color channel display data. If there are at least P display blocks and at least L columns of color channel display data in each display block conform to the preset pixel pattern, it can be quickly determined that the color channel display data of the current color channel conforms to the corresponding preset pixel pattern.

[0076] The embodiments of the present disclosure do not limit the specific size of the target detection area. For example, the target detection area can be the entire display area of ​​the display panel (correspondingly, it can be the entire display data of the image to be detected), or it can be a partial display area in the display panel (correspondingly, it can be a partial display data of the image to be detected).

[0077] See also Figure 3 , Figure 3 A schematic diagram of a target detection area according to an embodiment of the present disclosure is shown.

[0078] In one example, if Figure 3As shown, the target detection area can be determined using four corner coordinates (reg_hs, reg_vs), (reg_he, reg_vs), (reg_hs, reg_ve) and (reg_he, reg_ve). According to the specific detection requirements of the target detection area, the embodiment of the present disclosure can adaptively set the above four corner coordinates.

[0079] In a possible implementation, Figure 2 As shown, the method may also include:

[0080] Step S115: receiving target detection area indication information to determine the target detection area of ​​the image to be detected.

[0081] The embodiment of the present disclosure receives target detection area indication information to determine the target detection area of ​​the image to be detected, thereby achieving adaptive configuration of the target detection area. Exemplarily, the target detection area indication information may include four corner coordinates (reg_hs, reg_vs), (reg_he, reg_vs), (reg_hs, reg_ve) and (reg_he, reg_ve) in the display panel or the image to be detected.

[0082] The embodiments of the present disclosure do not limit the specific implementation method of indicating the target detection area indication information. Those skilled in the art can implement it in a suitable manner according to actual conditions and needs. For example, the embodiments of the present disclosure can use a valid data selection signal DE to indicate the target detection area indication information, wherein the valid data selection signal DE can be a composite signal of signals such as a line synchronization signal (Hsync) and a field synchronization signal (Vsync). Since in the video signal input to the display panel, the valid video signal (valid RGB signal) only occupies a part of the signal cycle, and the line blanking and field blanking periods of the signal do not contain valid video data. Therefore, when the relevant circuits in the display panel process the video signal, it is necessary to distinguish the interval containing the valid video signal from the blanking interval not containing the valid video signal. In order to distinguish between valid and invalid video signals, a valid data selection signal DE is set in the display panel. The above introduction to the valid data selection signal DE is exemplary and should not be regarded as a limitation to the embodiments of the present disclosure. For the specific introduction of the valid data selection signal DE, please refer to the description of the relevant technology. Of course, the embodiments of the present disclosure are not limited to only using the valid data selection signal DE to indicate the target detection area. Those skilled in the art can select a suitable method according to actual conditions and needs.

[0083] When the embodiment of the present disclosure divides the display blocks for multiple columns of color channel display data, the number of columns K included in the display blocks can be set according to actual conditions and needs. The embodiment of the present disclosure does not limit the specific size of K. For example, each display block can include 3 or 4 columns of color channel display data.

[0084] The preset pixel pattern may include the setting or arrangement of preset pixel parameters (such as brightness, chromaticity, etc.). The present disclosure does not limit the specific type of the preset pixel pattern, and those skilled in the art may set it according to actual conditions and needs. For example, the preset pixel pattern may include the number of brightness cycles of the color channel in each column of color channel display data, such as the number of cyclic changes of bright and dark levels. For example, the preset pixel pattern may include a target pixel pair having a number greater than a preset number in the pixels corresponding to each column of color channel display data, wherein the target pixel pair is: of two adjacent pixels, the color channel brightness of one pixel is less than the first brightness, the color channel brightness of the other pixel is greater than the second brightness, and the second brightness is greater than the first brightness.

[0085] See also Figure 4 , Figure 4 A brightness diagram according to an embodiment of the present disclosure is shown.

[0086] In one example, if Figure 4 As shown, the brightness less than the first brightness GSD can be called dark-level data, the brightness greater than the second brightness GSB can be called bright-level data, and the brightness between the first brightness GSD and the second brightness GSB can be called invalid data. It should be noted that the invalid data here refers to the brightness data ignored in the pixel detection of the preset pixel pattern of this example, that is, in this example, the embodiment of the present disclosure only detects the bright-level data and the dark-level data, and ignores the brightness data between the first brightness GSD and the second brightness GSB. Of course, the embodiment of the present disclosure is not limited to this, and those skilled in the art can set other preset pixel patterns. In other preset pixel patterns, there may be specific circumstances, so that the brightness data between the first brightness GSD and the second brightness GSB is also in the preset pixel pattern. The specific values ​​of the first brightness and the second brightness can be set as needed.

[0087] Exemplarily, the disclosed embodiment can perform brightness detection on each column of color channel display data, take two adjacent pixels as a group (the pixels of each group do not overlap), and count the number of target pixel pairs in each column of color channel display data to determine whether there are target pixel pairs greater than a preset number in the pixels corresponding to each column of color channel display data. Exemplarily, the disclosed embodiment can count each color channel display data separately. For example, the bright level data is represented by "1" and the dark level data is represented by "0", then the target pixel pairs can be pixels corresponding to consecutive "10" or "01", for example, in "101001", there are three target pixel pairs of "10", "10", and "01". The disclosed embodiment can store the bright level data and the dark level data through registers. For example, the distinguished dark level data and bright level data are respectively stored in two registers, and the output value 1 represents the bright level data, and the output value 0 represents the dark level data. By counting the number of target pixel pairs (corresponding to brightness data "10" or "01") in each column and comparing it with the preset number, the disclosed embodiment can determine whether there are more than the preset number of target pixel pairs in the pixels corresponding to the color channel display data in each column of each display block. If there are P display blocks, and each display block has L columns of color channel display data that conform to the preset pixel pattern, it is determined that the color channel display data of the current color channel conforms to the corresponding preset pixel pattern. The disclosed embodiment does not limit the specific size of the preset number, and those skilled in the art can set it according to actual conditions and needs. For example, the preset number can be any value between 0 and 16.

[0088] See also Figure 5 , Figure 5 A schematic diagram showing color channel display data according to an embodiment of the present disclosure is shown.

[0089] In one example, if Figure 5As shown, taking the color channel as the red channel as an example, taking the target detection area as the entire image as an example, the red channel display data includes M (0-m) columns and N (0-n) rows, a total of M×N red channel display data, arranged into M×N red channel display data (grayscale values), on this basis, the data type of the preset pixel style of each column (LINE0-LINEm) is defined as: two red channel display data for one cycle + two red channel display data are dark level data (i.e., the output value is 0) and bright level data (i.e., the output value is 1), that is, a target pixel pair. For example, if R0_0=reg_type00 (dark level 0) and R0_1=reg_type01 (bright level 1), the data type of the preset pixel style is consistent with the definition, and the statistical counter (counter) is accumulated by 1. Further, if R0_2=reg_type00 and R0_3=reg_type01, the counter is accumulated by 1 again. If the display panel is 1920 (columns) × 1080 (rows), then the same logic is used until all values ​​are calculated, and finally whether the horizontal style hit is met (i.e., the pixels corresponding to each column of color channel display data have a target pixel pair greater than the preset number) is determined based on whether the accumulated value of the counter corresponding to each column exceeds the preset number. Furthermore, the disclosed embodiment can perform vertical style hit statistics (i.e., determine whether there are at least P display blocks, and each display block has at least L columns of color channel display data that meet the preset pixel style), and count whether the number of display blocks that meet the horizontal style hit in the 1920 columns exceeds the critical value P. If so, it is determined that the color channel display data of the current color channel meets the corresponding preset pixel style.

[0090] The disclosed embodiments do not limit the manner in which display blocks are divided; display blocks may be divided in advance, or they may be divided when detecting a preset pixel pattern for each column of color channel display data; for example, the preset pixel pattern may be determined for each column of color channel display data in turn, and K consecutive columns of color channel display data may be defined as a block; if the color access display data that meets the corresponding preset pixel pattern (also referred to as meeting the horizontal pattern hit) in the K columns of color channel display data reaches L columns, the number of target blocks is increased by 1; if the number of target blocks reaches P, it is determined that the color channel display data of the current color channel meets the corresponding preset pixel pattern.

[0091] The embodiment of the present disclosure can determine that the image to be detected is a target detection image when it is determined that the color channel display data of at least one color channel conforms to the corresponding preset pixel style. Exemplarily, if it is determined that the color channel display data of each color channel conforms to the corresponding preset pixel style, the embodiment of the present disclosure can further improve the accuracy of determining that the image to be detected is a target detection image.

[0092] In a possible implementation, the method may further include:

[0093] Determines the brightness of each color channel for each pixel.

[0094] In a possible implementation, Figure 2 As shown, the method may also include:

[0095] Step S21, configure multiple preset pixel patterns, and synchronously perform pixel detection on each color channel display data of each pixel of the image to be detected. The image to be detected can be detected based on different preset pixel patterns.

[0096] The disclosed embodiment configures a plurality of preset pixel styles and synchronously performs pixel detection on the display data of each color channel of each pixel of the image to be detected, thereby improving the efficiency of pixel detection and avoiding missed detection. Moreover, for different preset pixel styles, the disclosed embodiment can adaptively adjust the parameters of the display panel (such as driving voltage, etc.) to solve the problem of inaccurate display when the display panel displays images corresponding to these preset pixel styles.

[0097] In a possible implementation, Figure 2 As shown, the method may also include:

[0098] Step S22: When it is determined that the image to be detected is a target detection image, the display parameters of the target detection image are adjusted.

[0099] The embodiment of the present disclosure can solve the problem of inaccurate display when the display panel displays images corresponding to these preset pixel patterns by adjusting the display parameters of the target detection image when determining that the image to be detected is a target detection image, thereby improving the accuracy of the image displayed by the display panel.

[0100] Of course, the embodiments of the present disclosure do not limit specific display parameters, and those skilled in the art can adaptively select display parameters that need to be adjusted according to different types and properties of display panels and problems caused by corresponding preset pixel styles.

[0101] See also Figure 6a and Figure 6b , Figure 6a and Figure 6b A schematic diagram of an electronic device according to an embodiment of the present disclosure is shown.

[0102] In one example, if Figure 6aAs shown, the electronic device may include, for example, a display panel 11a, a timing controller 121a (TCON, Timing Contoller), a gate driver 122a (or scan driver), and a source driver 123a (or data driver), wherein the display panel 11a includes M×N pixels, and each pixel includes a red sub-pixel (Red sub-pixel), a green sub-pixel (Green sub-pixel) and a blue sub-pixel (Blue sub-pixel).

[0103] In one example, in order to save circuit area and reduce power consumption, as Figure 6b As shown, the timing controller 121a, the gate driver 122a and the source driver 123a can be integrated into a single driver chip 12a, for example, the driver chip 12a can be a display driver chip (Display Driver IC, referred to as "DDIC"). Furthermore, the touch circuit, the timing controller 121a, the gate driver 122a and the source driver 123a can also be integrated into a single driver chip, for example, the driver chip 12a can be a touch display integrated chip (Touch and Display Driver Integration, TDDI).

[0104] In one example, during normal operation, the timing controller 121a receives display data transmitted by a host computer (such as an application processor of a mobile phone), and then controls the gate driver 122a and the source driver 123a according to the display data, thereby driving the display panel 11a to display images.
