Referring to fig. 1, fig. 1 shows a flowchart of an image detection method according to an embodiment of the present disclosure.

As shown in fig. 1, the method includes:

step S11, respectively carrying out pixel detection on each color channel display data of each pixel of an image to be detected to obtain a detection result;

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

The image detection method of the embodiment of the disclosure can be executed by a processing component or an electronic device such as a terminal including the processing component, a server, and the like, so as to realize that pixel detection is respectively performed on each color channel display data of each pixel of an image to be detected, and obtain a detection result, and determine that the image to be detected is a target detection image under the condition that the detection result indicates that the color channel display data of at least one color channel conforms to a corresponding preset pixel pattern. In one example, a processing component includes, but is not limited to, a single processor, or discrete components, or a combination of a processor and discrete components. The processor may comprise a controller having functionality to execute instructions in an electronic device, which may be implemented in any suitable manner, e.g., 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, micro-controllers, microprocessors or other electronic components. Within 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.

In one example, a Terminal, also referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a User, such as a handheld device with wireless connection capability, a vehicle-mounted device, etc. Currently, some examples of terminals are: a Mobile Phone (Mobile Phone), a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in Industrial Control (Industrial Control), a wireless terminal in unmanned driving (self driving), a wireless terminal in Remote Surgery (Remote medical Surgery), a wireless terminal in Smart Grid, a wireless terminal in Transportation Safety, a wireless terminal in Smart City (Smart City), a wireless terminal in Smart Home (Smart Home), a wireless terminal in car networking, and the like.

The specific Color channels of each pixel of the image to be detected are not limited, and the image to be detected may be converted into a required Color Space (Color Space), and in different Color spaces, the Color channels may have different classifications, for example, an RGB (red, green, blue) Color Space, an HSV (hue, saturation, value) Color Space, an HSL (hue, saturation, brightness/luminance) Color Space, a YUV (Y represents luminance, UV represents chromaticity) Color Space, and the like. The disclosed embodiments will be exemplarily described in terms of an RGB color space.

For example, the image to be detected according to the embodiment of the present disclosure may include M × N pixels, and M, N are all integers greater than 1, where M represents columns and N represents rows, each pixel of the image to be detected may include red channel display data, green channel display data, and blue channel display data, and accordingly, the red channel display data, the green channel display data, and the blue channel display data of the image to be detected all include M columns and N rows.

Referring to fig. 2, fig. 2 shows a flowchart of an image detection method according to an embodiment of the present disclosure.

In one possible implementation, as shown in fig. 2, the step S11 of performing pixel detection on the color channel display data of each pixel of the image to be detected respectively may include:

step S111, dividing multiple rows of color channel display data in a target detection area of the image to be detected according to color channel display data of a current color channel to obtain N display blocks, wherein each display block comprises K continuous rows of color channel display data, and K, N is not less than 1 and is an integer;

step S112, if the number of target blocks in the display blocks reaches P, determining that the color channel display data of the current color channel conforms to the corresponding preset pixel pattern, where the color channel display data conforming to the preset pixel pattern in the target blocks reaches L rows, where L is equal to or greater than K, P and equal to or greater than N, and L, P are integers.

The embodiment of the disclosure divides the multiple rows of color channel display data in the target detection area of the image to be detected aiming at the color channel display data of the current color channel to obtain N display blocks, each display block comprises continuous K rows of color channel display data, and if at least P display blocks exist and at least L rows of color channel display data in each display block accord with the preset pixel pattern, the color channel display data of the current color channel can be quickly determined to accord with the corresponding preset pixel pattern.

The specific size of the target detection area is not limited in the embodiments of the present disclosure, and for example, the target detection area may be the entire display area of the display panel (correspondingly, the entire display data of the image to be detected may be displayed), or may be a partial display area of the display panel (correspondingly, the partial display data of the image to be detected may be displayed).

Referring to fig. 3, fig. 3 shows a schematic diagram of a target detection area according to an embodiment of the disclosure.

In one example, as shown in fig. 3, the target detection area may be determined by using four corner coordinates (reg _ hs, reg _ vs), (reg _ he, reg _ vs), (reg _ hs, reg _ ve) and (reg _ he, reg _ ve), which may be adaptively set according to the specific detection requirement of the target detection area.

In one possible embodiment, as shown in fig. 2, the method may further include:

step S115, receiving target detection area indication information to determine the target detection area of the image to be detected.

The embodiment of the present disclosure may implement adaptive configuration of the target detection area by receiving target detection area indication information to determine the target detection area of the image to be detected, and the target detection area indication information may include, for example, 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.

The embodiment of the present disclosure does not limit the specific implementation manner of indicating the target detection area indication information, and those skilled in the art may implement the method in an appropriate manner according to actual situations and needs, for example, the embodiment of the present disclosure may indicate the target detection area indication information by using the valid data strobe signal DE, where the valid data strobe signal DE may be a composite signal of signals such as a line synchronization signal (Hsync) and a field synchronization signal (Vsync), and since in the video signals input to the display panel, the valid video signals (valid RGB signals) only occupy a part of the signal period, and the line blanking period and the field blanking period of the signals do not contain valid video data. Therefore, when processing a video signal, a relevant circuit in the display panel needs to distinguish between a section containing a valid video signal and a blanking section containing no valid video signal, and in order to distinguish between valid and invalid video signals, a valid data strobe signal DE is provided in the display panel. The above description of the valid data strobe signal DE is exemplary and should not be construed as a limitation to the embodiments of the present disclosure, and please refer to the description of the related art for a specific description of the valid data strobe signal DE, of course, the embodiments of the present disclosure are not limited to only using the valid data strobe signal DE to indicate the target detection region, and those skilled in the art can select an appropriate manner according to actual situations and needs.

When the display blocks of the multi-column color channel display data are divided, the column number K included in the display blocks can be set according to actual conditions and needs.

The preset pixel pattern may include a setting or arrangement of preset pixel parameters (e.g., luminance, chrominance, etc.). The specific type of the preset pixel pattern is not limited in the embodiments of the present disclosure, and those skilled in the art may set the preset pixel pattern according to actual situations and needs, for example, the preset pixel pattern may include the number of luminance cycles of color channels in each column of color channel display data, for example, the number of cyclic changes of a bright step and a dark step, and for example, the preset pixel pattern may include target pixel pairs having a number greater than a preset number in pixels corresponding to each column of color channel display data, where the target pixel pairs are: in two adjacent pixels, the color channel brightness of one pixel is less than a first brightness, and the color channel brightness of the other pixel is greater than a second brightness, wherein the second brightness is greater than the first brightness.

Referring to fig. 4, fig. 4 shows a luminance diagram according to an embodiment of the disclosure.

In one example, as shown in fig. 4, the luminance smaller than the first luminance GSD may be referred to as dark level data, the luminance larger than the second luminance GSB may be referred to as bright level data, and the luminance between the first luminance GSD and the second luminance GSB may be referred to as invalid data, and it should be noted that the invalid data herein refers to luminance data that is ignored in pixel detection of the preset pixel pattern of this example, that is, in this example, the present embodiment of the disclosure detects only the bright level data, the dark level data, and ignores the luminance data between the first luminance GSD and the second luminance GSB. Of course, the embodiments of the present disclosure are not limited thereto, and a person skilled in the art may set other preset pixel patterns, and in other preset pixel patterns, there may be a specific case such that the luminance data between the first luminance GSD and the second luminance GSB is also in the preset pixel pattern. The specific values of the first brightness and the second brightness can be set according to needs.

For example, the present disclosure may perform brightness detection on each column of color channel display data, and count the number of target pixel pairs in each column of color channel display data with every two adjacent pixels as a group (pixels of each group do not overlap), so as to determine whether there are more than a preset number of target pixel pairs in the pixels corresponding to each column of color channel display data, for example, the present disclosure may count each color channel display data, for example, the brightness order data is represented by "1", the dark order data is represented by "0", and the target pixel pairs may be consecutive pixels corresponding to "10" or "01", for example, three target pixel pairs of "10", and "01" exist in "101001". In the embodiment of the disclosure, the bright scale data and the dark scale data may be stored through a register, for example, the distinguished dark scale data and bright scale data are respectively registered by two registers, an output value 1 represents the bright scale data, and an output value 0 represents the dark scale data. By counting the number of target pixel pairs (corresponding to luminance data "10" or "01") in each column and comparing the counted number with a preset number, the embodiment of the present disclosure may determine whether there are target pixel pairs greater than the preset number in pixels corresponding to each column of color channel display data in each display block, and if there are P display blocks and there are L columns of color channel display data in each display block that meet the preset pixel pattern, determine that the color channel display data of the current color channel meet the corresponding preset pixel pattern. The specific size of the preset number is not limited in the embodiment of the present disclosure, and a person skilled in the art may set the preset number according to actual situations and needs, for example, the preset number may be any value between 0 and 16.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating color channel display data according to an embodiment of the disclosure.

In one example, as shown in fig. 5, taking the color channel as the red channel and the target detection area as the whole image, the red channel display data includes M (0 to M) rows and N (0 to N) rows, and the total of M × N red channel display data is arranged into M × N red channel display data (gray scale values), and on the basis of this, the data type defining the preset pixel pattern of each row (LINE0 to LINE) is: the two red channel display data is one cycle + the two red channel display data are respectively dark-level data (i.e., output value is 0) and bright-level data (i.e., output value is 1), i.e., one target pixel pair. For example, if R0_0 is reg _ type00 (dark level 0) and R0_1 is reg _ type01 (bright level 1), the counter (counter) of the statistics is incremented by 1 according to the data type of the defined preset pixel pattern. Further, if R0_2 is reg _ type00 and R0_3 is reg _ type01, the counter increments by 1. If the display panel is 1920 (columns) × 1080 (rows), and so on until all values are counted, finally, whether the horizontal pattern hit is met is determined according to whether the accumulated value of the counter corresponding to each column exceeds the preset number (that is, each column of color channel display data corresponds to a pixel having a target pixel pair with a number greater than the preset number). Further, the embodiment of the present disclosure may perform vertical pattern hit statistics (i.e., determine whether there are at least P display blocks and each display block has at least L rows of color channel display data corresponding to the predetermined pixel pattern), count whether the number of display blocks hit in the hit 1920 rows according to the horizontal pattern exceeds a threshold P, and if so, determine that the color channel display data of the current color channel corresponds to the corresponding predetermined pixel pattern.

The display block may be divided in advance, or may be divided when a preset pixel pattern of each row of color channel display data is detected, for example, each row of color channel display data may be sequentially judged to be the preset pixel pattern, and consecutive K rows of color channel display data are divided into one block, where if color access display data in accordance with the corresponding preset pixel pattern (which may also be referred to as being in accordance with a horizontal pattern hit) in the K rows of color channel display data reaches L rows, the number of target blocks is increased by 1, and if the number of target blocks reaches P, it is determined that the color channel display data of the current color channel corresponds to the corresponding preset pixel pattern.

In the embodiment of the present disclosure, under the condition that it is determined that the color channel display data of at least one color channel conforms to the corresponding preset pixel pattern, it may be determined that the image to be detected is the target detection image.

In one possible embodiment, the method may further include:

the respective color channel luminance of the respective pixel is determined.

In one possible embodiment, as shown in fig. 2, the method may further include:

step S21, configuring multiple preset pixel patterns, and synchronously performing 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.

According to the display panel and the display method, various preset pixel patterns are configured, the pixel detection is synchronously performed on the display data of each color channel of each pixel of the image to be detected, the pixel detection efficiency can be improved, the occurrence of missing detection is avoided, and for different preset pixel patterns, the display panel and the display method can adaptively adjust the parameters (such as driving voltage) of the display panel so as to solve the problem that the display panel is inaccurate when the display panel displays the images corresponding to the preset pixel patterns.

In one possible embodiment, as shown in fig. 2, the method may further include:

and step S22, adjusting the display parameters of the target detection image under the condition that the image to be detected is determined to be the target detection image.

According to the embodiment of the disclosure, under the condition that the image to be detected is determined to be the target detection image, the display parameters of the target detection image are adjusted, so that the problem of inaccurate display of the display panel when the image corresponding to the preset pixel patterns is displayed can be solved, and the accuracy of the display panel for displaying the image is improved.

Of course, the specific display parameters are not limited in the embodiments of the present disclosure, and those skilled in the art can adaptively select the display parameters to be adjusted according to the problems caused by different types, different attributes, and corresponding preset pixel patterns of the display panel.

Referring to fig. 6a and 6b, fig. 6a and 6b are schematic diagrams illustrating an electronic device according to an embodiment of the disclosure.

In one example, as shown in fig. 6a, the electronic device may include, for example, a display panel 11a, a Timing controller 121a (TCON), 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).

In one example, in order to save circuit area and reduce power consumption, as shown in fig. 6b, the timing controller 121a, the gate Driver 122a and the source Driver 123a may be integrated into a single driving chip 12a, for example, the driving chip 12a may be a Display Driver IC (DDIC). Furthermore, the Touch circuit, the timing controller 121a, the gate Driver 122a and the source Driver 123a may be integrated into a single driving chip, for example, the driving chip 12a may be a Touch and Display Driver Integration (TDDI).

In one example, in normal operation, the timing controller 121a receives display data transmitted from an upper computer (e.g., an application processor of a mobile phone), and then controls the gate driver 122a and the source driver 123a according to the display data, so as to drive the display panel 11a to display images.

In the embodiment of the present disclosure, under the condition that it is determined that the image to be detected is the target detection image, the display parameter of the target detection image is adjusted, for example, the driving chip 12a may be controlled, so as to adjust the display parameter of the target detection image, and thus, the display of the display panel is more accurate. Of course, the embodiments of the present disclosure do not limit the specific parameters, and those skilled in the art can select appropriate parameters to control according to actual situations and needs.
