Vehicle-mounted camera image processing device

Abstract

The invention discloses a vehicle-mounted camera image processing device which effectively solves the problems that in the prior art, a driver and passengers cannot know the specific reason that a dark screen or a white screen appears in an image collected by a vehicle-mounted camera, and the driving safety of a vehicle in the driving process and the use of the vehicle are affected. The processing device comprises a detection circuit, a judgment circuit and an output circuit, the detection circuit utilizes a power sensor U1 to detect power signals output by a power supply for a vehicle-mounted camera, compares the power signals, outputs a first level to the judgment circuit, compares voltage signals output by the power supply to output a second level to the judgment circuit. the judgment circuit judges the first level and the second level and starts the output circuit, and the output circuit obtains the difference signal and the water vapor signal and transmits the difference signal and the water vapor signal to the ECU, so that the safety of the vehicle in the running process and the use of the vehicle are ensured.

Description

Technical field [0001] The present invention relates to the field of cameras, particularly an in-vehicle camera image processing apparatus. Background technique [0002] The car camera is an indispensable an important electronic assistant system that guarantees the safety of the car, which greatly enhances the safety performance of driving, and has the function of real-time video and audio. It is convenient for the driving experience of the car to see the car inside and outside the vehicle, providing safety protection for vehicles. It is also an analysis of traffic accidents, it is determined to provide a reliable credential, so it has become an indispensable hardware for traffic safety. [0003] However, in the actual application, the image collected by the car camera is extremely easy to appear image dark or white screen. After careful investigation, it is found that it is not a problem of contactless contact, but is related to power supply, power supply power supply. Seavild l...
