[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Currently, LED displays typically employ constant current output, achieving different grayscale levels by varying the display duration. Each individual LED pixel uses 16-bit red, green, and blue (RGB) pixels, enabling the display of 65536*65536*65536 different grayscale levels. Figure 1-1 As shown, LED beads are controlled by the display chip to open at different widths to correspond to different grayscale levels. The smallest unit is the grayscale clock (GCLK). A single-color LED bead per pixel can achieve an open width of 0 to 65535 pixels within one frame. LED displays typically distribute the total grayscale time into various sub-frames, such as... Figure 1-2 The 4-scan LED display shown has its grayscale 16 divided into 4 grayscale 4 segments, breaking down one subframe into 4 subframes. Currently, as shown... Figure 1-3As shown, when the shutter speed is shorter than the length of the LED display frame, grayscale is missing (for example, when shooting frame 1, the shutter only captures part of the sub-frame and cannot capture all the grayscale). Figure 1-4 As shown, grayscale distortion occurs when the shutter speed is longer than the length of the LED display frame (e.g., when shooting frame 1, the shutter speed captures a portion of frame 2 in addition to frame 1). Figure 1-5 As shown, bright and dark lines occur when the shooting shutter and the scanning lines are out of sync (for example, during the shutter speed, lines 1, 2, and 4 are displayed twice, while line 3 is displayed three times, resulting in line 3 being significantly brighter than lines 1, 2, and 4 when the images in each line are consistent, thus causing the bright and dark line problem on the display screen).

[0036] See Figure 2 The diagram shows a flowchart of a synchronous shooting method, which mainly includes the following steps S202 to S206:

[0037] Step S202: Obtain display frame information from the target display device and shooting information from the image acquisition device. The shooting information includes shooting frames, i.e., shutter speed information, which includes shutter speed and non-shutter speed.

[0038] In one implementation, the acquired information also includes data and control information and clock input. The initial grayscale clock of the variable grayscale clock GCLK is determined by the clock input. The initial grayscale clock is the smallest grayscale unit corresponding to the display frame information.

[0039] Step S204: Determine the grayscale control signal based on the initial display frame information and the shooting information. The grayscale control signal is used to adjust the display frame information of the target display device so that the adjusted display frame information matches the shooting information.

[0040] In one implementation, adaptive synchronization adjustment can be performed by changing the grayscale clock length, breaking the display frame information into multiple sub-frames, and dividing the display frame information / sub-frames into multiple target display sub-frames on an average basis, and the grayscale control signal is determined based on the adjustment result.

[0041] Step S206: Control the image acquisition device to acquire the adjusted display frame image of the target display device based on the shooting information. The adjusted display frame information is completely synchronized with the shutter speed in the shooting information.

[0042] In one embodiment, initial display data of the target display device is acquired, and the target display device is controlled by current and pulse to adjust the image display content according to the initial display data and the shooting information, and the adjusted display data of the target display device is acquired again.

[0043] The synchronous shooting method provided in this embodiment of the invention can generate a grayscale control signal based on the display frame information and the shooting information, and control the display frame image of the target display device through the grayscale control signal, so that the display frame information and the shooting information are synchronized, reducing the grayscale missing rate, thereby significantly improving the shooting effect of the LED display screen.

[0044] In one implementation, the shooting information includes at least shutter speed information. This embodiment of the invention provides an implementation for determining the grayscale control signal, as detailed in (1) to (3) below.

[0045] (1) Obtain the preset initial grayscale clock, where the initial grayscale clock is the smallest grayscale unit corresponding to the display frame information.

[0046] In one implementation, the initial grayscale clock is the minimum grayscale unit corresponding to the pre-set display frame information. When the shutter time and display frame cannot be fully synchronized, the grayscale can be fully presented by adjusting the initial grayscale clock.

[0047] (2) This embodiment of the invention also provides an implementation method for dividing each type of display frame information according to shutter time information and initial grayscale clock to obtain multiple target display sub-frames corresponding to each display frame information, as detailed in (a) to (c) below:

[0048] (a) Adjust the initial grayscale clock according to the shutter time information to obtain the target grayscale clock.

[0049] In one implementation, the number of line scans is determined based on shutter time information and target grayscale clock, the number of subframes corresponding to the display information is determined based on the number of line scans, and the number of line scans is determined as the number of subframes corresponding to the display frame information.

[0050] (b) For each type of display frame information, determine the number of subframes and the subframe length corresponding to that display frame information based on the shutter time information and the target grayscale clock. The shutter time information includes shutter time and non-shutter time, and the number of subframes indicates the number of times the target display device repeats the target display subframe during the non-shutter time.

[0051] In one implementation, the image content is repeated even at non-shutter times of the captured frame to avoid flickering to the human eye.

[0052] In one implementation, the shutter speed information can be the number of subframes corresponding to the captured frame and the length of the subframes.

[0053] (c) Divide the display frame information according to the number of subframes and the length of the subframes to obtain multiple target display subframes corresponding to the display frame information.

[0054] In one implementation, such as Figure 3 As shown, if the display time corresponding to the display frame information is not greater than the shutter time, the display frame information is divided into multiple target display subframes according to the shutter time, the number of subframes, and the subframe length; wherein, the display time of the recombined display frame corresponding to the multiple target display subframes is synchronized with the shutter time.

[0055] In one implementation, when the display time corresponding to the display frame information is not greater than the shutter time, the display frame information does not need to be broken into multiple sub-frame images; instead, the shutter time is synchronized with the display frame only by synchronous control.

[0056] In one implementation, if the display time corresponding to the display frame information is greater than the shutter time, the display frame information is broken down into multiple sub-frame images based on the number of sub-frames and the sub-frame length. Each sub-frame image is then divided into multiple target display sub-frames. Each type of display frame information includes multiple identical total display frames, each total display frame having the same number of sub-frames and the same sub-frame length.

[0057] In one implementation, when the frame rate cannot meet the corresponding shutter speed, there will inevitably be a partial grayscale loss in one frame of the image. By using the grayscale scattering provided by the logic control scattering unit, it is possible to ensure that all grayscale information is captured as much as possible. By adjusting the subframe length, the shutter speed is captured completely over N subframes (a complete N line scan cycle), thereby ensuring that the number of times each line is displayed remains consistent during shooting and avoiding the problem of bright and dark lines.

[0058] In one implementation, such as Figure 4 As shown, during the 4-scan operation, the first group displays grayscale data in one go before wrapping to the next line; the second group distributes grayscale values ​​according to 1, 2, 4, and 8; and the third group is evenly distributed and grouped according to 4, 4, 4, 4. Within the shown shutter speed, the first group loses the information of the 3rd and 4th lines, resulting in only the first two lines being bright; the second group only captures the grayscale value of the first line (6) and the grayscale value of the remaining lines (2), resulting in a bright and dark line distribution; and the third group, through even distribution and subframe synchronization technology, presents the preset 4 lines of display data relatively evenly and completely.

[0059] (3) Determine the control signal based on the multiple target display subframes corresponding to each display frame information.

[0060] In one implementation, a current control module is added to the timing control unit. In addition to adjusting the grayscale through pulses, current control is added, and control signals are sent to the image acquisition device through a combination of pulse width adjustment and current modulation to achieve grayscale display.

[0061] In practical applications, such as Figure 5The diagram shows a structural schematic of an LED display driver chip with a built-in synchronization module. The display device includes an LED display driver chip and an LED display screen. The LED display driver chip includes: an information acquisition module, an autonomous adjustment module, and an information transmission module. The information acquisition module includes a synchronization processing module and a clock control unit. The autonomous adjustment module includes a storage control unit. The information transmission module includes a variable current channel output module and a scan line drive module. The synchronization processing module acquires display frame information and image capture information, determines a first control signal based on the display frame information and image capture information, and sends the first control signal to the clock control unit. The clock control unit acquires a clock input and adjusts the first control signal based on the clock input to determine a second... The system first sends a control signal and then sends a second control signal to the storage control unit. The storage control unit adjusts the second control signal based on data and control information to determine a target control signal, and sends the target control signal to the variable current channel output module and the scan line drive module. The variable current channel output module sends the target control signal to the LED display screen, and the scan line drive module determines the number of line scans and sends the number of line scans to the LED display screen. The LED display screen includes an LED array system, which is a selection of a group consisting of a micro-LED array, a single-millimeter LED array, a quantum dot LED array, an organic LED array, and a micro-organic LED array. The storage control unit can be a Static Random Access Memory (SRAM). The LED display driver chip uses a synchronization processing module (SRAM) to store information and perform logic control, timing control, and current control. In one embodiment, the synchronization processing module in the LED display driver chip autonomously adjusts the display information based on the received external shutter synchronization signal and frame synchronization signal. It also adjusts the grayscale value of the clock by clock frequency multiplication based on changes in shutter time and the initial grayscale clock to obtain the target grayscale clock after the grayscale value change. Based on the autonomous adjustment result of the synchronization processing module, the variable current channel output module performs pulse width adjustment and current modulation to achieve grayscale display. The scanning line drive module outputs the number of line scans. In another embodiment, the synchronization processing module added inside the chip can adaptively synchronize frames according to changes in shutter speed. It also adaptively adjusts the grayscale scattering module and the line scan control module inside the chip. The adaptive algorithm can significantly reduce grayscale loss and eliminate scanning bright and dark lines. Furthermore, it can generate a grayscale control signal based on the display frame information and shooting information, and control the display frame image of the target display device through the grayscale control signal, synchronizing the display frame information with the shooting information, reducing the grayscale loss rate, and thus significantly improving the shooting effect of the LED display screen.

[0062] To facilitate understanding of the synchronous shooting method provided in the above embodiments, this invention provides an application example of the synchronous shooting method, see below. Figure 6 The flowchart of another synchronous shooting method shown here mainly includes the following steps S602 to S610:

[0063] Step S602: Obtain display frame information from the target display device and shooting information from the image acquisition device. The shooting information includes shooting frames, i.e., shutter speed information, which includes shutter speed and non-shutter speed.

[0064] In one implementation, the acquired information also includes data and control information and clock input. The initial grayscale clock of the variable grayscale clock GCLK is determined by the clock input. The initial grayscale clock is the smallest grayscale unit corresponding to the display frame information.

[0065] Step S604: Obtain a preset initial grayscale clock, and adjust the initial grayscale clock according to the display frame information and shooting information to obtain the target grayscale clock. The initial grayscale clock is the smallest grayscale unit corresponding to the display frame information.

[0066] In one implementation, the initial grayscale clock is the minimum grayscale unit corresponding to the pre-set display frame information. When the shutter time and display frame cannot be fully synchronized, the grayscale can be fully presented by adjusting the initial grayscale clock.

[0067] Step S606: Divide the display frame information based on the target grayscale clock to obtain multiple target display subframes.

[0068] In one implementation, such as Figure 3 As shown, if the display time corresponding to the display frame information is not greater than the shutter time, the display frame information is divided into multiple target display subframes according to the shutter time, the number of subframes, and the subframe length; wherein, the display time of the recombined display frame corresponding to the multiple target display subframes is synchronized with the shutter time.

[0069] In one implementation, when the display time corresponding to the display frame information is not greater than the shutter time, the display frame information does not need to be broken into multiple sub-frame images; instead, the shutter time is synchronized with the display frame only by synchronous control.

[0070] In one implementation, if the display time corresponding to the display frame information is greater than the shutter time, the display frame information is broken down into multiple sub-frame images based on the number of sub-frames and the sub-frame length. Each sub-frame image is then divided into multiple target display sub-frames. Each type of display frame information includes multiple identical total display frames, each total display frame having the same number of sub-frames and the same sub-frame length.

[0071] In one implementation, when the frame rate cannot meet the corresponding shutter speed, there will inevitably be a partial grayscale loss in one frame of the image. By using the grayscale scattering provided by the logic control scattering unit, it is possible to ensure that all grayscale information is captured as much as possible. By adjusting the subframe length, the shutter speed is captured completely over N subframes (a complete N line scan cycle), thereby ensuring that the number of times each line is displayed remains consistent during shooting and avoiding the problem of bright and dark lines.

[0072] Step S608: Determine the grayscale control signal based on the division of the target display subframes. The grayscale control signal is used to adjust the display frame information of the target display device so that the adjusted display frame information matches the captured information.

[0073] In one implementation, adaptive synchronization adjustment can be performed by changing the grayscale clock length, breaking the display frame information into multiple sub-frames, and dividing the display frame information / sub-frames into multiple target display sub-frames on an average basis, and the grayscale control signal is determined based on the adjustment result.

[0074] Step S610: Control the target display device to adjust the display information according to the grayscale control signal, so that the display frame information is completely synchronized with the shooting information. Specifically, the adjusted display frame information is completely synchronized with the shutter speed in the shooting information.

[0075] In one embodiment, initial display data of the target display device is acquired, and the target display device is controlled by current and pulse to adjust the image display content according to the initial display data and the shooting information, and the adjusted display data of the target display device is acquired again.

[0076] In summary, the present invention can generate a grayscale control signal based on the display frame information and the shooting information, and control the display frame image of the target display device through the grayscale control signal, so that the display frame information and the shooting information are synchronized, reducing the grayscale loss rate, thereby significantly improving the shooting effect of the LED display screen.
