REDUNDANT VIDEO PATH FOR VEHICLE REAR VIEW CAMERA SYSTEM

A rear view video system for a vehicle includes a display and a rear view camera that generates a raw video signal. A video modification module receives the raw video signal and generates a modified video signal based thereon. A video analysis module analyzes whether the modified video signal is valid or invalid. A switch outputs the modified video signal to the display when the vehicle is in reverse and the modified video signal is valid and outputs the raw video signal to the display when the vehicle is in reverse and the modified video signal is invalid. 种用于车辆的后视视频系统包括显示器和产生原始视频信号的后视摄像机。视频修正模块接收原始视频信号并且基于所述原始视频信号产生修正的视频信号。视频分析模块分析修正的视频信号是有效的还是无效的。切换器在车辆处于倒车且修正的视频信号有效时将修正的视频信号输出到显示器，并且在车辆处于倒车且修正的视频信号无效时将原始视频信号输出到显示器。
