Description

Technical Field

[0001] This disclosure relates to the field of image processing technology, and in particular to a method, apparatus, and computer device for processing pixel data. Background Technology

[0002] With the development of display technology, the testing of display modules has become particularly important. In the testing of display modules, due to the different driving signal standards (such as MIPI, LVDS, V-BY-ONE, etc.), the different display resolutions (such as from 240P to 8K), and the different display module driver ICs (Integrated Circuits) from different manufacturers, the arrangement of display pixel data and the storage method of image pixel data in memory will be quite different. Therefore, the pixel data of various images in memory need to be processed differently before they can be displayed normally in the display module.

[0003] In traditional pixel data processing, corresponding processing programs are usually developed for different display modules to support the display of different display modules.

[0004] However, traditional pixel data processing programs suffer from lengthy development and debugging cycles, and each display module requires its own corresponding processing program, making it difficult to quickly support the display of different display modules. Summary of the Invention

[0027] The pixel data to be refreshed in the refresh area is determined based on the refresh area in the target display module;

[0028] Based on the correspondence between the pixel data to be refreshed, the pixel data displayed in the target display module, and the source pixel data, the target refresh pixel data that needs to be refreshed in the refresh area of ​​the source pixel data is determined.

[0050] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this disclosure.

[0051] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings herein are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, apparatus, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0052] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0053] As described in the background section, in traditional technologies, the pixel data is typically arranged in a consistent order, such as A, B, C, D, E. During reading, the data is usually read and written in this order. The order in which the data is written to the display module is also typically the same as the pixel data arrangement order. However, due to differences in display modules, many modules cannot display data correctly according to the pixel data arrangement order, which affects the detection of display modules. Furthermore, since the detection equipment needs to test various types of display modules, setting up a corresponding processing program for each type of display module would be extremely time-consuming. Therefore, there is an urgent need for a method that can quickly process pixel data during the display module detection process, enabling it to rapidly support the display of different display modules.

[0054] To address the aforementioned problems, embodiments of this disclosure provide a pixel data processing method, which can be applied to, for example... Figure 1 In the application environment shown, the test machine 102 communicates with the test server 104 via a network. The test machine 102 is used to test the display module. The test machine 102 can acquire source pixel data, which is the pixel data corresponding to the image that the target display module needs to display. The test machine 102 can select a corresponding processing method to process the source pixel data according to the display mode of the target display module to obtain the target pixel data. The test machine 102 can output the target pixel data to the target display module to instruct the target display module to display the image according to the target pixel data. The test server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0055] In one embodiment, such as Figure 2 As shown, a method for processing pixel data is provided, which can be applied to... Figure 1 Taking the test machine 102 as an example, the following steps are included:

[0056] S202, Obtain source pixel data, wherein the source pixel data is the pixel data corresponding to the image that the target display module needs to display.

[0057] In some embodiments of this disclosure, the target display module is typically an OLED (Organic Light-Emitting Diode) module panel, and specifically the OLED module panel to be detected. The source pixel data can be pixel data arranged in a certain order; typically, the source pixel data can be arranged according to the order of the pixel data corresponding to the displayed image. For example, if the pixel data in the image to be displayed are A, B, C, and D, their arrangement order is... Then the source pixel data can usually also be Arrange the images. The images to be displayed are typically those needed for detection during the detection process.

[0058] Specifically, under normal circumstances, the test machine 102 can obtain instructions issued by the test server 104, or obtain a configuration file pre-stored in the test machine 102, and retrieve source pixel data from the instructions or configuration file. Typically, in some embodiments of this disclosure, the source pixel data is usually in matrix form, which facilitates processing and reading.

[0059] In some exemplary embodiments, acquiring the source pixel data includes:

[0060] The source pixel data is obtained based on the storage information of the source pixel data, wherein the storage information includes: storage space information, file name information, mapping address information, and shared memory identifier information.

[0061] Specifically, source pixel data can exist in files, mappings, storage spaces, or shared memory. Source pixel data can be retrieved using file names, storage space information, mapping address information, shared memory identifier information, etc.

[0062] S204, according to the display mode of the target display module, select the corresponding processing method to process the source pixel data to obtain the target pixel data.

[0063] The display mode can include: 1. Displaying pixel data of a normal image; 2. Displaying pixel data in a specific order within each row; 3. Displaying pixel data according to certain preset rules; 4. Refreshing the display of pixel data; 5. Displaying certain areas according to certain preset rules, etc. The target pixel data is typically pixel data obtained by processing pixel data sequentially. The display mode can be provided in advance by the target display module manufacturer, or it can be obtained through testing before inspecting the target display module. The display mode can also include the resolution of the pixel data.

[0064] Specifically, the target display module can be tested first to determine its display mode. Alternatively, the display mode can be determined based on information provided by the target display module manufacturer. Based on the target display module's display mode, a corresponding processing method is selected to process the source pixel data, thereby obtaining the target pixel data.

[0065] For example, pixel data The input is given to the target display module, and the pixel data displayed in the target display module is... This allows us to determine the display mode, where pixel data in each row is displayed in a specific order. We can then choose a reorganization method to process the data and obtain the target pixel data. It's important to understand that the above is merely an illustrative example. For instance, pixel data can be... The input is given to the target display module, and the pixel data displayed in the target display module is... This allows us to determine that the display mode is to display pixel data according to certain preset rules, and we can choose a region combination method for processing. It is understood that the above is only for illustrative purposes.

[0066] S206, the target pixel data is output to the target display module to instruct the target display module to display an image based on the target pixel data.

[0067] Specifically, the target pixel data can be output to the target display module. The target display module can read the target pixel data and then display an image based on the target pixel data.

[0068] Additionally, the test machine can store the target pixel data as a contiguous framebuffer or a region of memory, either in the ARM's DDR, the ARM's framebuffer, or the FPGA's DDR, depending on the predefined target location. Other elements include the offset address or offset address list of the target pixel data relative to the source pixel data, and the size of the matrix representing the target pixel data relative to the source pixel data.

[0069] For example, the target pixel data is The target display module displays pixel data in a specific order for each row. Because this order is used, after reading the target pixel data, the target display module can display the following pixel data: This allows the image to be displayed correctly and used for testing. For example, the target pixel data is... Because its display mode involves displaying pixel data according to certain preset rules, the target display module can only display a limited amount of pixel data after reading the target pixel data. The image can be displayed correctly and used for testing. It is understood that the above is for illustrative purposes only.

[0070] In the above pixel data processing method, since there are various types of target display modules, when it is necessary to test the target display module using source pixel data, the corresponding processing method can be selected according to the display mode of the target display module to process the source pixel data, ensuring that the processed target pixel data can support the normal display of the target display module. Then, the target pixel data can be output to the target display module to instruct it to display an image based on the target pixel data. During the detection process, it can adapt to different types of target display modules, enabling the target display module to quickly display images and ensuring the detection efficiency. Furthermore, since the source pixel data is processed according to the display mode, there is no need to develop different processing programs, reducing the detection cycle and time, and further improving detection efficiency.

[0071] In one embodiment, such as Figure 3 As shown, the step of selecting a corresponding processing method to process the source pixel data according to the display mode of the target display module to obtain the target pixel data includes:

[0072] S302, based on the display mode of the target display module, select at least one processing method and determine the processing order of each processing method. The processing methods include: reassembly method, splicing method, area refresh method, segmentation method, and area combination method.

[0073] Specifically, since the target display modules may have different display modes, multiple processing methods may be required to enable the target display modules to display normally. Therefore, at least one processing method can be selected according to the display mode of the target display module. In addition, the final pixel data arrangement result will also be different due to the different processing order. Therefore, it is also necessary to determine the processing order of each processing method.

[0074] For example, a target display module needs to first process the target pixel data according to certain preset rules, and then process the pixel data of each row in a certain order before it can be displayed normally. Therefore, the processing order can be to first perform the area combination method and then the recombination method.

[0075] S304, the source pixel data is processed sequentially according to the processing order by selecting the corresponding processing method to obtain the target pixel data; wherein, the output result of the processing method at the first position in the processing order is the input result of the processing method at the second position, the first position and the second position are adjacent, and the order of the first position is higher than the order of the second position.

[0076] Specifically, when determining the processing order, there are usually at least two processing methods. Therefore, the source pixel data can be processed sequentially according to the processing order to obtain the target pixel data. Typically, the output of the previous processing method can be used as the input of the next processing method.

[0077] For example, such as Figure 4 As shown, the processing methods are in the following order: segmentation and recombination. The segmentation method is processed first, and then the result of the segmentation method is used as the input for the result of the recombination method.

[0078] In this embodiment, by combining different processing methods and determining the order of processing methods, it is possible to adapt to the display modes of different target display modules, ensuring that the target display modules can display images normally, thereby ensuring the accuracy of detection.

[0079] In one embodiment, such as Figure 5 As shown, the method further includes:

[0080] S402, in response to the processing method being a row pixel data recombination method, the pixel data in the corresponding row of the source pixel data is adjusted according to the recombination control parameters relative to the recombination method.

[0081] The recombination control parameters are typically parameters that control how the recombination is performed. For example, the third to fifth pixel data in each row may be recombinated. How the pixel data in each row is recombined can be determined by those skilled in the art based on the display mode. Therefore, in some embodiments of this disclosure, the recombination control parameters are not limited.

[0082] Specifically, when the processing method is reconstruction, the pixel data of each row is typically reconstructed. The pixel data of each row in the source pixel data can be adjusted according to the reconstruction control parameters corresponding to the reconstruction method.

[0083] In some exemplary embodiments, taking a target display module driven by dual MIPI ICs as an example, the odd and even pixels displayed by the target display module are output by two driver ICs respectively. However, each driver IC receives source pixel data from the left and right halves respectively. This means that a complete image cannot be displayed correctly in the target display module without processing. Therefore, this situation requires processing by reassembling the row pixel data. For example, if a row of source pixel data has 16 pixels, they can be identified as ABCDEFGHIJKLMNOP, where each letter represents one RGB pixel. Due to differences in drive signals, they may need to be stored in the FrameBuffer in the form of AIBJCKDLEMFNGOHP or ABIJCDKLEFMNGHOP (pixel coordinate adjustment). Taking a common two-channel MIPI dual-driver IC drive module as an example, the coordinate correspondence between the output pixel data and the input pixel data is as follows:

[0084] The input source pixel data matrix coordinates are (x, y), (x≥0, y≥0), and the corresponding output pixel data matrix coordinates are (m, n), (m≥0, n≥0). The size of the input source pixel data matrix is ​​X×Y. Following this correspondence, the pixel data in each row can be adjusted. This ensures that the adjusted pixel data in each row is input into the target display module, allowing the target display module to correctly display the corresponding pixel data for that row.

[0085] S404, in response to the processing method being a row pixel data splicing method, adjust the pixel data in the corresponding row of the source pixel data according to the splicing control parameters corresponding to the splicing method.

[0086] The splicing control parameters typically control how the data is reassembled. For example, splicing the first and third pixel data in each row, splicing the second and fourth pixel data, and so on.

[0087] Specifically, the stitching method is similar to the recombination method. When the processing method is recombination, it typically involves stitching together the pixel data of each row. The pixel data of each row in the source pixel data can be adjusted according to the stitching control parameters corresponding to the stitching method.

[0088] For example, continuing with a target display module driven by dual MIPI ICs, the splicing method is the opposite of the reconstruction method. The left and right display areas of the target display module are output by different driver ICs, and the data received by each driver IC from the source pixels is distributed according to the parity of the pixel data. In this case, splicing is required. A specific example of the splicing operation can be found by referring to the reverse of the reconstruction method described above, and will not be repeated here. Typically, the splicing and reconstruction methods are opposite and therefore cannot be performed consecutively simultaneously; for example, splicing followed by reconstruction, or vice versa.

[0089] In this embodiment, by processing through recombination or splicing, it can be ensured that the target display module can display a complete image.

[0090] In one embodiment, such as Figure 6 As shown, the method further includes:

[0091] S502, in response to the target display module needing to perform a region refresh, a refresh region in the target display module is determined, and pixel data to be refreshed in the refresh region and target refresh pixel data to be refreshed in the refresh region are determined.

[0092] S504, replace the pixel data to be refreshed in the source pixel data with the target refresh pixel data.

[0093] The refresh area can be the entire display area or a portion of the display area in the target display module. The target refresh pixel data can be the pixel data that needs to be refreshed.

[0094] Specifically, when a refresh is needed in the target display module, the area to be refreshed can be determined first. Then, the pixels to be refreshed within the refresh area can be identified. These pixels can be replaced with the target refresh pixel data, and then the replaced pixel data in the source pixel data can be displayed according to the processing method corresponding to the target display module, thus completing the area refresh of the target display module.

[0095] In some embodiments, determining the pixel data to be refreshed in the refresh area and the target refresh pixel data to be refreshed in the refresh area includes:

[0096] The pixel data to be refreshed in the refresh area is determined based on the refresh area in the target display module;

[0097] Based on the correspondence between the pixel data to be refreshed, the pixel data displayed in the target display module, and the source pixel data, the target refresh pixel data that needs to be refreshed in the refresh area of ​​the source pixel data is determined.

[0098] The correspondence can be determined based on information provided by the target display module manufacturer, or it can be determined by testing the target display module during the testing phase.

[0099] Specifically, since the arrangement of displayed pixel data differs significantly from the way image pixel data is stored in memory, the pixel data to be refreshed in the refresh area can be determined first based on the refresh area in the target display module. Then, based on the correspondence between the pixel data displayed in the target display module and the source pixel data, as well as the pixel data to be refreshed, the target refresh pixel data that needs to be refreshed in the refresh area of ​​the source pixel data is determined.

[0100] In some exemplary embodiments, the example of a target display module driven by dual MIPI ICs will continue to be used for illustration. If the area to be refreshed in the source pixel data is [(x, y), (x+h, y+v)] with a starting point of (x, y), and the width and height to be refreshed are h and v respectively, then the target display module's... or

[0101] Then, the refresh area in the corresponding target display module can be:

[0102] Based on the above conditions, the correspondence between the area to be refreshed and the actual refresh area of ​​the target display module can be determined. Based on this relationship, the pixel data to be refreshed in the source pixel data corresponding to the area to be refreshed can be determined, and then the corresponding pixel data to be refreshed can be replaced with the target pixel data.

[0103] In other exemplary embodiments, for example, after determining the area to be refreshed in the target display module, the pixel data corresponding to the area to be refreshed is found. For example, the pixels stored in the source pixel data are: The data is processed according to the specified method, and after the target display module is displayed, the pixel data displayed by the target display module is... If A2 and A4 constitute the refresh area that needs to be refreshed, then the pixel data at position A2 in the source pixel data and the pixel data at position A4 in the source pixel data need to be replaced. Only in this way can the area formed by the pixel data of A2 and A4 in the target display module after replacement be refreshed.

[0104] In one embodiment, such as Figure 7 As shown, the method further includes:

[0105] S602, in response to the processing method being a segmentation method, the source pixel data is segmented according to the segmentation offset corresponding to the segmentation method.

[0106] The segmentation offset can be determined based on the display mode.

[0107] Specifically, in some scenarios, due to different ways of the target display module reading pixel data. For example, the pixel data is , and its order is A0, A1, A4, A3, A6, A7, A2, A5, A8. Only after such reading can it be displayed normally. Therefore, the display mode can be determined by the reading order, and then the processing method can be determined as the segmentation method. Therefore, the source pixel data can be segmented according to the segmentation offset corresponding to the segmentation method. For the above example of pixel data, the source pixel data can be segmented into two parts according to the segmentation offsets 2 and 1 respectively and .

[0108] In some exemplary embodiments, for example, in the scenario where a V-BY-ONE multi-Driver IC drives target display modules in different regions, the source pixel data needs to be segmented into 4 pieces in a 'field' shape so that the target display modules in different regions can be combined and displayed normally. Therefore, the source pixel data can be segmented according to the segmentation offsets 0, X×Y×3 / 4, X×Y×3×2 / 4, X×Y×3×3 / 4, where X is the width of the matrix in the source pixel data and Y is the length of the matrix in the source pixel data.

[0109] S604. In response to the processing method being the area combination method, select a preset number of adjacent pixel data from the source pixel data.

[0110] S606. Adjust the arrangement of the preset number of adjacent pixel data according to the adjustment method corresponding to the area combination method.

[0111] Specifically, the tester cannot be compatible with all display modules. Therefore, in some scenarios where the line sequences do not correspond, for example, the tester only has a lane1 interface, while the target display module has lane1 and lane2 interfaces. At this time, since all the source pixel data is transmitted to the target display module through the lane1 interface, when transmitting the source pixel data at this time, the pixel data transmitted through the lane1 interface needs to be adjusted. Or, in the actual usage scenario, the input and output definitions of the connection wires do not have a unified standard, and it may occur that lane2 corresponds to lane4 and lane3 corresponds to lane5. Therefore, the connection order of the line sequences will also cause the target display module to not be able to display video data normally. To save hardware costs, it can be directly processed by software in the tester. At this time, a preset number of adjacent pixel data can be selected from the source pixel data. For example, a part of the pixel data can be selected, or all the pixel data can be selected. The specific number of selections can be determined according to the wiring method of the actual target display module. Adjust the arrangement of the preset number of adjacent pixel data according to the adjustment method corresponding to the area combination method.

[0112] For example, the source pixel data is When the target display module receives the data, due to a problem with the wiring sequence, the displayed pixel data is... In this case, the incorrect pixel data positions of A1, A2, A4, and A5 will cause the image to be displayed incorrectly in that area. Therefore, the preset adjacent pixel data can be determined as follows: The pixel data is iterated and adjusted until the image is displayed correctly, and then the final result is adjusted to... Then the adjusted pixel data is transmitted to the target display module.

[0113] In some embodiments, selecting a preset number of adjacent pixel data from the source pixel data and adjusting the arrangement of the preset number of adjacent pixel data according to the adjustment method corresponding to the region combination method includes:

[0114] A basic operation unit of a preset size is selected from the source pixel data, and the basic operation unit includes a preset number of adjacent pixel data;

[0115] The preset number of adjacent pixel data in the basic operation unit are traversed in the source pixel data, and the arrangement of the preset number of adjacent pixel data is adjusted.

[0116] Specifically, a region can be selected from the source pixel data. This region can be a basic operation unit of a preset size, which includes a preset number of adjacent pixel data. The pixel data in the basic operation unit can be all the source pixel data or a portion of the source pixel data, depending on the actual needs. When there is a problem with the entire line sequence, all the source pixel data can be selected to form the basic operation unit. When there is a problem with a portion of the line sequence, a portion of the source pixel data can be selected to form the basic operation unit. Then, the preset number of adjacent pixel data in the basic operation unit can be traversed in the source pixel data, reading the pixel data in the basic operation unit in a specific way, and then continuously adjusting the arrangement of the preset number of adjacent pixel data based on the reading stage.

[0117] In some exemplary embodiments, typically, a basic operation unit (N×M) matrix can be selected in the source pixel data (where n is divisible by the width h of the source pixel data matrix, and m is divisible by the height v of the source pixel data matrix).
