Abstract
A vehicle-mounted rear view camera system relates to the field of automobile electronic technologies, and the technical problem that rear view camera frames jitter is solved. The system comprises a vehicle-mounted pick-up head, a middle control unit and a front processing unit. The middle control unit comprises a middle control processor and a serial data decoding module which are connected to each other through a data bus, and a middle control display connected to the middle control processor. The front processing unit comprises a video decoding module and a serial data decoding module which are connected to each other through a data bus. A video signal output port of the vehicle-mounted pick-up head is connected to the video decoding module of the front processing unit, and a serial data output port of the serial data decoding module is connected to a serial data input port of the serial data decoding module through a difference cable. The system can prevent rear view camera frames from jittering.
