Abstract

The invention provides a wide temperature image processing board supporting ultrahigh definition signal long-distance transmission, which belongs to the field of video processing devices. The wide temperature image processing board comprises a video preprocessing module and a video processing module. The output end of the video preprocessing module is connected with the video processing module. The video preprocessing module comprises a number of video preprocessing units. The video processing module comprises a storage device, a control system, a video processing unit and a video integration unit. The video preprocessing module further comprises a number of video equalization units. Each video equalization unit comprises a de-static unit, a noise reduction unit and a video equalization amplification unit. According to the invention, a video equalization unit is added in front of each video preprocessing unit, so that the high definition video signal transmission distance is greatly improved from original 2m to 6m.

Description

technical field [0001] The invention relates to the field of video processing devices, in particular to a wide-temperature image processing board supporting long-distance transmission of ultra-high-definition signals. Background technique [0002] At present, there are more and more demands for ultra-high-definition 3840X2160 resolution display on the market, and there are also extensive demands in the military, especially the demand for splicing display of 4XDVI high-definition signals.
