Abstract

The invention belongs to the technical field of video information processing, and discloses a video image display method, apparatus and system based on the CameraLink protocol. The method comprises the following steps: receiving a frame of video data output by a camera through a CameraLink interface; extracting and storing a video image contained in the frame of video data; detecting the resolution of the video image; determining a resolution mode corresponding to the resolution of the video image; generating a corresponding DVI clock signal and a DVI image synchronization signal according to the resolution mode; and sending the DVI clock signal, the DVI image synchronization signal and the video image to a DVI display through a digital video interface DVI, so that the DVI display displays the video image according to the DVI clock signal and the DVI image synchronization signal. By adoption of the video image display method, apparatus and system disclosed by the invention, the video data output from the CameraLink interface can be directly converted into video data that can be identified by the DVI, so the video image output from the CameraLink interface can be displayed by using the DVI display without using a computer, thereby being convenient to implement.

Description

Technical field [0001] The invention relates to the technical field of video information processing, in particular to a video image display method, device and system based on the CameraLink protocol, which can be applied to the fields of digital video monitoring and display. Background technique [0002] With the increase in the speed of digital image acquisition and the increase in storage capacity, the original communication standard between the camera and the image acquisition card is no longer applicable, and the CameraLink standard came into being. The CameraLink interface protocol is an industrial high-speed serial port data and connection standard, which can simplify the image acquisition interface and facilitate the connection between high-speed digital cameras and data acquisition cards. [0003] The image output interfaces of the existing high-speed digital cameras all use the standard CameraLink interface, and although the CameraLink interface can match the transmission ...
