Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, an embodiment of the present invention provides a video display system 10 with a multi-LED (Light Emitting Diode) display screen, where the video display system 10 with the multi-LED display screen includes: a main LED display screen 11 and a sub LED display screen 12, and further comprises a first chip 13 for controlling the sub LED display screen 12 and a second chip 14 for controlling the main LED display screen 11.
Optionally, the first chip 13 and the second chip 14 may be chips such as a CPU (Central Processing Unit), an MCU (micro control Unit), an FPGA (Field Programmable Gate Array), and the types of the chips may be selected according to the requirement of Processing capability.
In this embodiment, the second chip 14 prestores a video stream to be displayed by splicing the main LED display screen 11 and the sub LED display screen 12, and the second chip 14 may send each frame image in the video stream to the first chip 13 frame by frame. If a certain frame of image is interfered during transmission, the first chip 13 can repair and restore the image by using the previous frame of image to avoid distortion of the image due to interference. In this way, when the second chip 14 controls the main LED display 11 to display a certain frame of image, the first chip 13 also controls the sub LED display 12 to synchronously display the frame of image or the frame of repaired image, so that the main LED display 11 and the sub LED display 12 display the display content in the frame of image in a splicing manner.
How the first chip 13 repairs the image will be described in detail by the method embodiment.
Referring to fig. 2, the present embodiment provides an anti-interference video display method for a sub-LED display screen, where the anti-interference video display method for the sub-LED display screen may be executed by the first chip 13, and the anti-interference video display method for the sub-LED display screen may include:
step S100: and receiving the current frame image transmitted by the second chip, wherein the display content in the current frame image needs to be spliced and displayed by the main LED display screen and the sub LED display screens.
Step S200: and judging whether the current frame image is interfered in the transmission process according to the difference between the current frame image and the previous frame image transmitted by the second chip.
Step S300: and if the current frame image is interfered, restoring the current frame image by using the previous frame image.
Step S400: and controlling the sub LED display screens to display the repaired current frame image so as to splice the display contents of the main LED display screen and the sub LED display screens.
The following describes steps S100 to S400 in order.
Step S100: and receiving the current frame image transmitted by the second chip, wherein the display content in the current frame image needs to be spliced and displayed by the main LED display screen and the sub LED display screens.
In order to realize that the main LED display screen 11 and the sub LED display screen 12 are used to display the display content in a splicing manner, the second chip 14 needs to send each frame of image in the video stream to the first chip 13 frame by frame according to the playing sequence, and then when the current frame of image needs to be played, the second chip 14 transmits the current frame of image to the first chip 13 on time. Correspondingly, the first chip 13 receives the current frame image whose display content in the image needs to be tiled and displayed by the main LED display screen 11 and the sub LED display screen 12.
Step S200: and judging whether the current frame image is interfered in the transmission process according to the difference between the current frame image and the previous frame image transmitted by the second chip.
If there are interference signals of other devices covering the transmission path between the second chip 14 and the first chip 13 during the transmission of the current frame image, the current frame image will be interfered and the image will be distorted. And because the time interval between every two frames of images is very short, normally, every two frames of images can be highly similar. In other words, when the current frame image is interfered to cause image distortion, the difference between the current frame image and the previous frame image transmitted before the second chip 14 is relatively large, wherein the previous frame image may be an undisturbed image or an interfered but restored image. Therefore, after receiving the current frame image, the first chip 13 may compare the current frame image with the previous frame to determine a difference between the current frame image and the previous frame, and determine that the current frame image is interfered during transmission according to the difference.
It should be noted that in this way, it is necessary to ensure that the first frame image transmitted by the second chip 14 to the first chip 13 is not disturbed. In general, the occurrence of interference is a phenomenon that occurs by chance, for example, someone holding an electronic device that is likely to cause interference moves near the second chip 14, and thus there is a high probability that there is no interference in transmitting the first frame image.
In the present embodiment, as a first exemplary way of determining the difference between the current frame image and the previous frame image, the first chip 13 may generate a display screen of the current frame image and generate a display screen of the previous frame image. The first chip 13 superimposes the display picture of the current frame image and the display picture of the previous frame image, and determines the difference part between the display picture of the current frame image and the display picture of the previous frame image by analyzing the display content in the images, wherein the display content in the same area of the current frame image and the previous frame image is gradually changed, so the display picture of the area is the same part in the current frame image and the previous frame image; and the display content in the same area of the current frame image and the previous frame image changes suddenly, so the display picture of the area is the difference part between the current frame image and the previous frame image.
Further, the first chip 13 determines a difference degree between the display frame of the current frame image and the display frame of the previous frame image according to the area size of the difference portion, and compares the difference degree with a preset difference threshold value to determine whether the difference degree is greater than the preset difference threshold value, where the difference degree greater than the difference threshold value indicates that the current frame image is interfered during transmission.
In the present embodiment, as a second exemplary way to determine the difference between the current frame image and the previous frame image, the first chip 13 determines the data structure of the current frame image by analyzing the image data of the current frame image, and determines the data structure of the previous frame image by analyzing the image data of the previous frame image.
It can be understood that, when the display contents in the same region of the current frame image and the previous frame image are gradually changed, the data structure of the image data corresponding to the region in the current frame image is almost the same as the data structure of the image data corresponding to the region in the previous frame image; on the contrary, when the display content in the same region of the current frame image and the previous frame image changes suddenly due to the interference, the data structure of the image data corresponding to the region in the current frame image and the data structure of the image data corresponding to the region in the previous frame image have a great difference. Therefore, the first chip 13 can determine data having a data structure of the current frame image that is greatly different from that of the previous frame image by comparing the data structure of the current frame image with that of the previous frame image.
Further, the first chip 13 correspondingly determines a difference degree between the data structure of the current frame image and the data structure of the previous frame image according to the amount of the data with large difference, and compares the difference degree with a preset difference threshold value to determine whether the difference degree is greater than the preset difference threshold value, wherein the greater the amount of the data with large difference, the greater the difference degree is, and the greater the difference degree is, the more the current frame image is interfered in the transmission process.
For example, as shown in fig. 3, in the data structure of the previous frame image, it includes a1 partial data, B1 partial data, and C1 partial data. When the current frame image is not disturbed, it includes a2 partial data almost identical to the a1 partial data, a B2 partial data almost identical to the B1 partial data, and a C2 partial data almost identical to the C1 partial data in the data structure of the current frame image. But when the current frame image is disturbed, it includes a2 partial data that is almost the same as the a1 partial data, a D1 partial data that is greatly different from the B1 partial data, and an E1 partial data that is greatly different from the C1 partial data in the data structure of the current frame image.
Step S300: and if the current frame image is interfered, restoring the current frame image by using the previous frame image.
In this embodiment, a plurality of image restoration engines are preset in the first chip 13, so as to efficiently restore the interfered image of each frame. For example, if the rate of the video stream is 30 frames per second, the number of image inpainting engines may be 30. In this way, if the video within one second is interfered, 30 frames of images within one second can be input to 30 image restoration engines for restoration in a one-to-one correspondence manner, so as to ensure that the restoration speed of the images can keep up with the playing speed of the video.
After determining that the current frame image is interfered, the first chip 13 may determine the image restoration engines capable of processing the current frame image from a plurality of preset image restoration engines, for example, the first chip 13 may cyclically and sequentially determine whether each image restoration engine is operated at full load according to the display sequence of the images to determine a first image restoration engine that is not operated at full load, where the first image restoration engine that is not operated at full load is the image restoration engine capable of processing the current frame image.
Further, the first chip 13 may input the current frame image and the previous frame image into the determined image inpainting engine. The determined image restoration engine may replace the display content in the difference portion of the current frame image with the corresponding display content in the current frame image, for example, if the a area in the current frame image is the difference portion, the image restoration engine may replace the display content in the a area of the current frame image with the display content in the B area of the previous frame image having the same position as the a area. And the image restoration engine can also predict the change trend of the display content and slightly adjust the display content replaced in the area A by utilizing the change trend so as to better blend the display content with the display content outside the area A in the current frame image.
Further, after the repairing is completed, the determined image repairing engine may output the repaired current frame image. Correspondingly, the first chip 13 obtains the repaired current frame image.
Step S400: and controlling the sub LED display screens to display the repaired current frame image so as to splice the display contents of the main LED display screen and the sub LED display screens.
In this embodiment, in order to facilitate that each frame of image can be output according to the playing sequence of the video, a plurality of storage areas are further preset in the first chip 13, and each storage area corresponds to one image restoration engine. Thus, when the current frame image does not need to be repaired, the first chip 13 can directly cache the current frame image into a corresponding storage area according to the display sequence of the image; when the current frame image needs to be repaired, the first chip 13 may cache the repaired current frame image in a storage area corresponding to the determined image repair engine.
It can be understood that, by buffering the images, the first chip 13 and the second chip 14 can relieve the stress of the image restoration engine in a time-lapse display manner, and ensure that the images of the frames can be correctly displayed in sequence. For example, the first chip 13 and the second chip 14 jointly agree to display the current frame image delayed by 5 seconds from the time when the current frame image is received by the first chip 13. This 5 second delay then ensures that the current frame image has been repaired before display.
When the delay is completed, it indicates that the repaired current frame image can be displayed at this time, the first chip 13 extracts the repaired current frame image from the storage area, and controls the sub LED display 12 to display the repaired current frame image, so that the display contents of the main LED display 11 and the sub LED display 12 are spliced.
In addition, the first chip 13 also detects the storage water level of each storage area in real time, and determines that the storage water level of a certain storage area exceeds a preset water level threshold; the first chip 13 controls the image restoration engine corresponding to the storage area to suspend the ongoing restoration work.
Referring to fig. 4 in conjunction with fig. 1, based on the same inventive concept, an embodiment of the present application provides an anti-interference video display apparatus 100 for a sub-LED display screen, which is applied to control a first chip 13 displayed by a sub-LED display screen 12, and the apparatus includes:

Optionally, the image processing module 120 is configured to generate a display frame of the current frame image and a display frame of the previous frame image; determining the difference degree between the display picture of the current frame image and the display picture of the previous frame image; judging whether the difference degree is larger than a preset difference threshold value or not; or
