The embodiment of the present application accumulates pixels of the pre-acquired image to be displayed to obtain a calculation result, and then determines the appropriate power level based on the calculation result, and sends the power level to the light board end through the data frame. Therefore, based on the corresponding power level, the light board end can be controlled to display each frame of the image to be displayed, thereby reducing the energy loss of the light board and extending the service life of the light board.

[0054] The embodiments of the present application take into account that currently, during the process of displaying images on a vehicle light board, its power easily exceeds the maximum allowable power, which will shorten the service life of the light board.

[0055] Therefore, the embodiment of the present application proposes a solution by accumulating pixels of the pre-acquired image to be displayed to obtain a calculation result, and then determining the appropriate power level based on the calculation result, and sending the power level to the light board end through a data frame. Therefore, based on the corresponding power level, the light board end can be controlled to display each frame of the image to be displayed, thereby reducing the energy consumption loss of the light board and extending the service life of the light board.

[0056] Specifically, referring to Figure 1, Figure 1 is a schematic diagram of the functional modules of a terminal device to which the display data processing device of the present application belongs. The display data processing device can be a device independent of the device that is capable of performing data processing and can be hosted on the device in the form of hardware or software.

[0063] The data frame is sent to the light board end, so that the light board end displays each frame of the image to be displayed based on the power level and the image information.

[0064] Furthermore, when the display data processing program in the memory 130 is executed by the processor, the following steps are also implemented:

[0065] Calculating the initial brightness level of at least one lamp bead when the lamp board displays each frame of the image;

[0066] Correcting the lamp beads based on the calculation result and an initial brightness level of at least one of the lamp beads to obtain a corrected brightness level;

[0067] The power level of each frame of the picture is determined based on the corrected brightness level.

[0068] Furthermore, when the display data processing program in the memory 130 is executed by the processor, the following steps are also implemented:

[0069] When the calculation result is greater than a first calculation result threshold and less than or equal to a second calculation result threshold, the lamp bead is corrected according to the initial brightness level of the lamp bead;

[0070] If the initial brightness level of the lamp bead is greater than or equal to the third brightness level threshold, the brightness level of the lamp bead is reduced by one to obtain the corrected brightness level.

[0071] Furthermore, when the display data processing program in the memory 130 is executed by the processor, the following steps are also implemented:

[0072] When the calculation result is greater than the second calculation result threshold and less than or equal to the third calculation result threshold, the lamp bead is corrected according to the initial brightness level of the lamp bead;

[0073] If the initial brightness level of the lamp bead is greater than or equal to the fourth brightness level threshold, reducing the brightness of the lamp bead by two levels to obtain the corrected brightness level;

[0074] If the initial brightness level of the lamp bead is greater than or equal to the second brightness level threshold and less than the fourth brightness level threshold, the brightness level of the lamp bead is reduced by one to obtain the corrected brightness level.

[0075] Furthermore, when the display data processing program in the memory 130 is executed by the processor, the following steps are also implemented:

[0076] When the calculation result is greater than the third calculation result threshold, the lamp bead is corrected according to the initial brightness level of the lamp bead;

[0077] If the initial brightness level of the lamp bead is greater than or equal to the fifth brightness level threshold, then reducing the brightness level of the lamp bead by three to obtain the corrected brightness level;

[0078] If the initial brightness level of the lamp bead is greater than or equal to the third brightness level threshold and less than the fifth brightness level threshold, the brightness of the lamp bead is reduced by two levels to obtain the corrected brightness level;

[0079] If the initial brightness level of the lamp bead is greater than or equal to the first brightness level threshold and less than the third brightness level threshold, the brightness level of the lamp bead is reduced by one to obtain the corrected brightness level.

[0080] Furthermore, when the display data processing program in the memory 130 is executed by the processor, the following steps are also implemented:

[0081] Writing the current frame sequence number into the first two bytes of the corresponding data frame;

[0082] The power level is written into the third byte of the corresponding data frame.

[0083] Furthermore, when the display data processing program in the memory 130 is executed by the processor, the following steps are also implemented:

[0084] receiving a data frame sent by a terminal, the data frame including image information and a power level written by the terminal, the power level being determined based on a calculation result obtained after the terminal accumulates pixels of a pre-acquired image to be displayed;

[0085] Each frame of the image to be displayed is displayed based on the power level.

[0086] This embodiment adopts the above scheme, specifically by accumulating pixels of the pre-acquired image to be displayed to obtain a calculation result; determining the power level of each frame of the image to be displayed based on the calculation result; writing the picture information and power level of each frame of the image into the corresponding data frame; sending the data frame to the light board end, so that the light board end can display each frame of the image to be displayed based on the power level and the picture information. The embodiment of the present application obtains a calculation result by accumulating pixels of the pre-acquired image to be displayed, and then determines the appropriate power level based on the calculation result, and sends the power level to the light board end through the data frame. Therefore, based on the corresponding power level, the light board end can be controlled to display each frame of the image to be displayed, thereby reducing the energy loss of the light board and extending the service life of the light board.

[0087] Based on the above device architecture but not limited to the above architecture, an embodiment of the method of the present application is proposed.

[0088] The execution subject of the method of this embodiment may be a display data processing device, which may be a device independent of the device and capable of performing data processing, and may be hosted on the device in the form of hardware or software.

[0089] 2 is a flow chart of an exemplary embodiment of a display data processing method of the present application. The method is applied to a control terminal and includes:

[0090] Step S10 , performing pixel accumulation on the pre-acquired image to be displayed to obtain a calculation result.

[0091] The image to be displayed is a signature, picture, video uploaded by the user, or an image drawn by the user in real time.

[0092] If the image to be displayed is a moving picture, a video, or an image drawn by a user in real time, the image to be displayed may be split into several pictures.

[0093] Then, the pictures are divided based on the preset time unit.

[0094] Here, assuming that the image to be displayed is decomposed into 30 pictures in total, and one preset time unit corresponds to 10 pictures, then the image to be displayed can be divided into 3 groups in sequence based on the time unit.

[0095] Then, pixel data of the image in at least one time unit is accumulated to obtain a calculation result of the group.

[0096] For example, based on the three groups of pictures obtained by the above division, pixel accumulation can be performed on the first, second, and third groups of pictures respectively to obtain a calculation result corresponding to at least one group of pictures.

[0097] Specifically, each pixel in the image corresponds to a 4-bit grayscale value. The calculation result of the group is obtained by accumulating each pixel in the image. The equation is as follows: SubArray_x = sum of (all of 4-bit data) (x ∈ [1, n] represents the nth image in a group of images).

[0098] Among them, SubArray_x represents the calculation result of the nth picture in a group of pictures.

[0099] Then, after obtaining the calculation results corresponding to at least one group of pictures, the calculation results corresponding to at least one group of pictures are filtered respectively, and the equation is as follows: pixel_filter_x = sum of (SubArray_x) / TimeWindow.

[0100] Among them, TimeWindow is the filtering processing factor.

[0101] Then, the maximum value among the calculation results corresponding to the at least one group of pictures after filtering is used as the calculation result of the image to be displayed, and the equation is as follows: Pixel_max_x = max(at least one group pixel_filter_x).

[0102] Step S20: determining the power level of each frame of the image to be displayed based on the calculation result.

[0103] The calculation result may be associated with the power level, so that the corresponding power level may be determined based on the calculation result.

[0104] Specifically, as an implementation method, the initial brightness level of at least one lamp bead when the light board displays each frame of the picture can be calculated.

[0105] Then, the lamp beads are corrected based on the calculation result and the initial brightness level of at least one of the lamp beads to obtain a corrected brightness level.

[0106] Finally, the power level of each frame of the picture is determined based on the corrected brightness level.

[0107] Step S30: writing the picture information and power level of each frame of the picture into the corresponding data frame.

[0108] The image information may include: image size, current frame number of the image, image type, etc.

[0109] For a data frame corresponding to each frame of picture, the picture information and power level of the frame of picture may be written into a preset position in the data frame.

[0110] Step S40: sending the data frame to the light board end, so that the light board end displays each frame of the image to be displayed based on the power level and the image information.

[0111] Among them, after the control end sends the data frame to the light board end, the light board end reads the power level and picture information in the preset position of the data frame, and then displays the frame image based on the power level and picture information.

[0112] As an implementation method, taking the image to be displayed as an image drawn by the user in real time as an example, when the user draws the image, the real-time drawn image will be directly sent to the light board end for real-time display, thereby improving the synchronization of image display. At the same time, the image drawn by the user is used as the image to be displayed, and steps S10-S40 are executed to calculate the power level of each frame of the image to be displayed, and the power level is sent to the light board end. After the light board end displays the image drawn by the user in real time, when it loops or redisplays the image drawn by the user, it uses the power level determined in step S20 to display the image to be displayed. Therefore, when the image drawn by the user is redisplayed or looped, the energy loss of the light board can be reduced, thereby extending the service life of the light board.

[0113] This embodiment, through the above scheme, obtains a calculation result by accumulating pixels of the pre-acquired image to be displayed; determines the power level of each frame of the image to be displayed based on the calculation result; writes the picture information and power level of each frame of the image into the corresponding data frame; and sends the data frame to the light board end, so that the light board end can display each frame of the image to be displayed based on the power level and the picture information. This embodiment of the application obtains a calculation result by accumulating pixels of the pre-acquired image to be displayed, and then determines the appropriate power level based on the calculation result, and sends the power level to the light board end through the data frame. Therefore, based on the corresponding power level, the light board end can be controlled to display each frame of the image to be displayed, thereby reducing the energy loss of the light board and extending the service life of the light board.

[0114] 3 , which is a flow chart illustrating another exemplary embodiment of a data processing method according to the present application.

[0115] Based on the embodiment shown in FIG. 2 , the step S20 of determining the power level of each frame of the image to be displayed based on the calculation result includes:

[0116] Step S21, calculating and obtaining the initial brightness level of at least one lamp bead when the lamp board displays each frame of the image.

[0117] Among them, each lamp bead has 16 different brightness levels.

[0118] Among them, the initial brightness level of at least one lamp bead can be calculated based on the display content of each frame of the image.

[0119] Step S22: correcting the lamp beads based on the calculation result and the initial brightness level of at least one of the lamp beads to obtain a corrected brightness level.

[0120] The calculation result and the initial brightness level of at least one of the lamp beads can be comprehensively analyzed to obtain an analysis result, and the lamp bead can be corrected based on the analysis result to obtain a corrected brightness level.

[0121] Specifically, as an implementation, the calculation result and the initial brightness level of at least one of the lamp beads can be comprehensively analyzed to obtain an analysis result, a correction coefficient can be determined based on the analysis result, and then the correction coefficient can be used to correct the brightness level of the lamp bead.

[0122] As another implementation, different calculation result thresholds can be set based on the calculation results, and different brightness level thresholds can be set based on the brightness level of the lamp bead. The initial brightness level of the lamp bead can be analyzed to determine which calculation result threshold range and which brightness level threshold range the lamp bead falls into, and the analysis results can be obtained. The lamp bead can be corrected based on the analysis results to obtain the corrected brightness level.

[0123] Step S23: determining the power level of each frame of the image based on the corrected brightness level.

[0124] Among them, different brightness levels of the lamp beads correspond to different power levels.

[0125] Among them, based on the corrected brightness level, the corresponding lamp power level can be queried;

[0126] Then, the power levels of all the lamp beads in each frame of the picture are calculated. For example, the power levels of all the lamp beads in each frame of the picture are accumulated, and the accumulated result is used as the power level of the frame of the picture. Alternatively, the power levels of all the lamp beads in each frame of the picture are counted, and the power level with the largest proportion is used as the power level of the frame of the picture, and so on.

[0127] The embodiment of the present application corrects the lamp beads based on the calculation results and the initial brightness level of at least one of the lamp beads to obtain a corrected brightness level, and determines the power level of each frame of the image based on the corrected brightness level. This can control the power of the image to be displayed, reduce the energy consumption loss of the lamp board, and thus extend the service life of the lamp board.

[0128] 4 , which is a flow chart illustrating another exemplary embodiment of a data processing method according to the present application.

[0129] Based on the embodiment shown in FIG. 3 , step S22 of correcting the lamp beads based on the calculation result and the initial brightness level of at least one lamp bead to obtain the corrected brightness level includes:

[0130] Step S221: When the calculation result is greater than the first calculation result threshold and less than or equal to the second calculation result threshold, the lamp bead is corrected according to the initial brightness level of the lamp bead.

[0131] For example, assuming that the total number of lamp beads on the lamp board is 1712, the first calculation result threshold is set to 1080 and the second calculation result threshold is set to 1200.

[0132] Among them, when the calculation result is greater than 1080 and less than or equal to 1200, the number of light beads on the light board is greater than 1080 and less than 1200.

[0133] Step S222: If the initial brightness level of the lamp bead is greater than or equal to the third brightness level threshold, the brightness level of the lamp bead is reduced by one level to obtain the corrected brightness level.

[0134] For example, the first brightness level threshold is set to 5, the second brightness level threshold is set to 6, the third brightness level threshold is set to 10, the fourth brightness level threshold is set to 13, and the fifth brightness level threshold is set to 14.

[0135] Among them, when the calculation result is greater than the first calculation result threshold and less than or equal to the second calculation result threshold, if the initial brightness level of the lamp bead is 15 and greater than the third brightness level threshold 10, the brightness level of the lamp bead is reduced to 14.

[0136] In one embodiment, when the calculation result is less than the first calculation result threshold, the brightness level of the lamp bead remains unchanged.

[0137] The embodiment of the present application corrects the lamp beads based on the calculation results and the initial brightness level of at least one of the lamp beads to obtain a corrected brightness level, and determines the power level of each frame of the image based on the corrected brightness level. This can control the power of the image to be displayed, reduce the energy consumption loss of the lamp board, and thus extend the service life of the lamp board.

[0138] 5 , which is a flow chart illustrating another exemplary embodiment of a data processing method according to the present application.

[0139] Based on the embodiment shown in FIG. 3 , step S22 of correcting the lamp beads based on the calculation result and the initial brightness level of at least one lamp bead to obtain the corrected brightness level further includes:

[0140] Step S223: When the calculation result is greater than the second calculation result threshold and less than or equal to the third calculation result threshold, the lamp bead is corrected according to the initial brightness level of the lamp bead.

[0141] For example, assuming that the total number of lamp beads on the lamp board is 1712, the second calculation result threshold is set to 1200, and the third calculation result threshold is set to 1320.

[0142] Among them, when the calculation result is greater than 1200 and less than or equal to 1320, the number of lighted lamp beads on the lamp board is greater than 1200 and less than 1320.

[0143] Step S224: If the initial brightness level of the lamp bead is greater than or equal to the fourth brightness level threshold, the brightness level of the lamp bead is reduced by two levels to obtain the corrected brightness level.

[0144] For example, the fourth brightness level threshold is 13 as described in the previous embodiment.

[0145] Among them, when the calculation result is greater than the second calculation result threshold and less than or equal to the third calculation result threshold, if the initial brightness level of the lamp bead is 15 and greater than or equal to the fourth brightness level threshold 13, the brightness level of the lamp bead is reduced to 13.

[0146] Step S225: If the initial brightness level of the lamp bead is greater than or equal to the second brightness level threshold and less than the fourth brightness level threshold, the brightness level of the lamp bead is reduced by one to obtain the corrected brightness level.

[0147] For example, the second brightness level threshold is 6 as described in the previous embodiment.

[0148] Among them, when the calculation result is greater than the second calculation result threshold and less than or equal to the third calculation result threshold, if the initial brightness level of the lamp bead is 12, which is greater than the second brightness level threshold 6 and less than the fourth brightness level threshold 13, the brightness level of the lamp bead is reduced to 11.

[0149] The embodiment of the present application corrects the lamp beads based on the calculation results and the initial brightness level of at least one of the lamp beads to obtain a corrected brightness level, and determines the power level of each frame of the image based on the corrected brightness level. This can control the power of the image to be displayed, reduce the energy consumption loss of the lamp board, and thus extend the service life of the lamp board.

[0150] 6 , which is a flowchart illustrating another exemplary embodiment of a data processing method according to the present application.

[0151] Based on the embodiment shown in FIG. 3 , step S22 of correcting the lamp beads based on the calculation result and the initial brightness level of at least one lamp bead to obtain the corrected brightness level further includes:

[0152] Step S226: When the calculation result is greater than the third calculation result threshold, the lamp bead is corrected according to the initial brightness level of the lamp bead.

[0153] For example, assuming that the total number of lamp beads on the lamp board is 1712, the third calculation result threshold is 1320.

[0154] Among them, when the calculation result is greater than 1320, the number of light beads on the light board is greater than 1320.

[0155] Step S227: If the initial brightness level of the lamp bead is greater than or equal to the fifth brightness level threshold, the brightness level of the lamp bead is reduced by three to obtain the corrected brightness level.

[0156] For example, the fifth brightness level threshold is 14 as described in the embodiment shown in FIG. 4 .

[0157] Among them, when the calculation result is greater than the third calculation result threshold, if the initial brightness level of the lamp bead is 15, which is greater than the fifth brightness level threshold 14, the brightness level of the lamp bead is reduced to 12.

[0158] Step S228: If the initial brightness level of the lamp bead is greater than or equal to the third brightness level threshold and less than the fifth brightness level threshold, the brightness level of the lamp bead is reduced by two levels to obtain the corrected brightness level.

[0159] For example, the third brightness level threshold is 10 as described in the embodiment shown in FIG. 4 .
