Description

technical field [0001] The invention belongs to the technical field of digital video processing, and relates to a real-time video anti-reflection instrument with high definition and high frame rate. Background technique [0002] Video anti-reflection instruments currently mainly use physical processing and electronic processing. Physical processing often uses high-end fog-permeable lenses. This solution is expensive and has limited anti-reflection capabilities, and is not suitable for more user needs. Most of the electronic processing adopts DSP or PC, and the enhanced algorithm is realized through software programming. The processing speed of this solution is very slow. In order to ensure the real-time performance of video processing, methods such as reducing the video frame rate and reducing the video size are mostly used. Moreover, existing video anti-reflection instruments can only process standard definition video. With the development of semiconductor technology, th...
