Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As shown in fig. 1, a flowchart of a method for capturing an image ghost according to an embodiment of the present application includes the following steps:
s101: after receiving the respective image signals output by the signal source, the screen refresh rate of each image signal is adjusted so that the screen refresh rate of each image signal is equal to the preset image capturing frequency of the camera corresponding to each image signal.
The image signal includes, but is not limited to, a video stream, a video, and the like. The preset image capturing frequency of each camera may be the same or different from each other. Accordingly, the screen refresh rate of each image signal may be the same or different from each other.
Specifically, assuming that the signal source outputs 4 image signals, which are a first signal, a second signal, a third signal, and a fourth signal, respectively, the preset imaging frequency of the camera corresponding to the first signal is 60Hz, the preset imaging frequency of the camera corresponding to the second signal is 120Hz, the preset imaging frequency of the camera corresponding to the third signal is 120Hz, the preset imaging frequency of the camera corresponding to the fourth signal is 240Hz, the screen refresh rate of the first signal is adjusted to 60Hz, the screen refresh rate of the second signal is adjusted to 120Hz, the screen refresh rate of the third signal is adjusted to 180Hz, and the screen refresh rate of the first signal is adjusted to 240Hz.
The number of image signals and the number of cameras are consistent.
In addition, the sum of preset shooting frequencies of the cameras is not larger than the maximum available screen refresh rate of the LED screen.
Generally, the number of signal sources can also be set by the skilled person according to the actual situation. When the number of signal sources is plural, the number of image signals output by each signal source is one.
S102: and sequencing the image signals to obtain an image signal sequence.
S103: and sequentially transmitting each image signal in the image signal sequence to the LED screen according to the sequence from low to high, and controlling the LED screen to display images shown by each image signal according to the screen refresh rate of each image signal.
While S103 is being performed, S105 may be concurrently performed.
The first image signal may be sent to the LED screen first, and after a preset interval time, the second image signal may be sent to the LED screen. The first image signal and the second image signal are two image signals with adjacent sequence bits in the image signal sequence, and the sequence bit of the first image signal is lower than that of the second image signal.
It should be noted that, the LED screen is controlled to display the image shown by each image signal according to the screen refresh rate of each image signal, so that the image ghost of each image can be displayed on the LED screen.
Specifically, it is assumed that the image signal sequence includes 4 image signals, which are a first signal, a second signal, a third signal, and a fourth signal in this order. The screen refresh rate of the first signal is 60Hz, the screen refresh rate of the second signal is 120Hz, the screen refresh rate of the third signal is 180Hz, and the screen refresh rate of the fourth signal is 240Hz. And sending the first signal to the LED screen in advance, and controlling the LED screen to display the image shown by the first signal according to the screen refresh rate of 60Hz. And after the preset interval time, sending a second signal to the LED screen, and controlling the LED screen to display an image shown by the second signal according to the screen refresh rate of 120 Hz. And after the preset interval time, sending a third signal to the LED screen, and controlling the LED screen to display an image shown by the third signal according to the screen refresh rate of 180 Hz. And after the preset interval time, sending the fourth signal to the LED screen, and controlling the LED screen to display the image shown by the fourth signal according to the screen refresh rate of 240Hz.
Specifically, it is assumed that the image signal sequence includes 2 image signals, which are a first signal and a second signal in this order. Wherein the screen refresh rate of the first signal is 90Hz and the screen refresh rate of the second signal is 90Hz. And sending the first signal to the LED screen in advance, and controlling the LED screen to display the image shown by the first image signal according to the screen refresh rate of 90Hz. And after a preset time interval, sending a second signal to the LED screen, and controlling the LED screen to display an image shown by the second signal according to a screen refresh rate of 90Hz.
From the above procedure, it can be seen that the image ghost displayed on the LED screen contains a plurality of images, q, and each image is displayed according to a different screen refresh rate.
S104: and sequencing the preconfigured cameras to obtain a camera sequence.
Wherein S102 and S104 may be performed concurrently.
The arrangement order of each camera in the camera sequence is consistent with the arrangement order of each image signal in the image signal sequence, that is, the order of each camera in the camera sequence is equal to the order of the image signal corresponding to each camera in the image signal sequence.
S105: and sending black field signals to each camera in the camera sequence in sequence according to the sequence from low to high, triggering each camera to shoot images displayed on the LED screen according to the preset shooting frequency.
The black field signal may be sent to the first camera first, and after a preset interval time, the black field signal may be sent to the second camera. The first camera and the second camera are two cameras with adjacent sequence positions in the camera sequence, and the sequence position of the first camera is lower than that of the second camera.
The so-called black field signal is essentially: mainly for ensuring that the pictures taken by all cameras are synchronized signals starting from the same phase. The synchronization signal is to keep all signals played at the same time, because the full tv signal is black in the beginning and ending fields, commonly known as black fields, for synchronization, and the synchronization signal for each field is at the beginning and the synchronization signal for each line is at the beginning of each line.
It should be noted that, the preset time interval may be equal to a time required for refreshing an image of the LED screen, specifically, assuming that an image shown by the first image signal is a first image, an image shown by the second image signal is a second image, and a screen refresh rate of the first image signal is 60Hz, and a screen refresh rate of the second image signal is 120Hz, the LED screen may display the first image in advance, and then after refreshing and displaying the second image, the preset time interval is equal to a time required for refreshing the second image after the LED screen displays the first image.
Specifically, assuming that the preset time interval is 16.66 milliseconds, the camera sequence includes camera a, camera B, camera C, and camera D, and the preset imaging frequencies of each of camera a, camera B, camera C, and camera D are 60Hz. A black field signal is sent to the camera a in advance so that the camera a shoots a first image displayed by the LED screen at 60Hz, and after an interval of 16.66 ms, a black field signal is sent to the camera B so that the camera B shoots a second image displayed by the LED screen at 60Hz, after an interval of 33.32 ms, a black field signal is sent to the camera C so that the camera C shoots a third image displayed by the LED screen at 60Hz, and after an interval of 49.98 ms, a black field signal is sent to the camera D so that the camera D shoots a fourth image displayed by the LED screen at 60Hz. The first image, the second image, the third image, and the fourth image are respectively from different image signals, and the screen refresh rate of each image signal is 60Hz.
According to the process, black field signals are sequentially sent to the cameras by using preset time intervals, so that each camera shoots different images displayed by the LED screen, and the purpose of shooting different images on one LED screen is achieved.
In this embodiment, by adjusting the screen refresh rate of each image signal so that the screen refresh rate of each image signal is equal to the preset image capturing frequency of the camera corresponding to each image signal, controlling the LED screen to display the image shown by each image signal according to the screen refresh rate of each image signal, and controlling each camera to capture the image displayed on the LED screen according to the preset image capturing frequency of the camera, compared with the prior art, the method can ensure that the image ghost formed by different images is displayed on the LED screen, and can also ensure that different cameras can capture the image displayed by the LED screen at different screen refresh rates, thereby achieving the effect of capturing different images on the same screen.

S203: and sending a black field signal to each camera, and triggering each camera to shoot the image displayed on the LED screen according to the preset shooting frequency.
