Method and device for eliminating camera flicker based on sensor detection

Abstract

The present invention provides a camera flicker elimination method and device based on sensor detection. The method includes: S1, the step of sampling ambient light signals; S2, the step of outputting original image data; S3, the step of extracting ambient light sampling signals; S4, the step of ambient light flickering The step of determining the frequency; S5, the step of updating the frame rate of the camera; S6, updating the exposure frequency of the ambient light signal sampling row according to the camera frame rate, and returning to the step of sampling the ambient light signal. The invention realizes the interference suppression of light interference of various flickering frequencies and superimposed lights of various flickering frequencies, keeps video images stable, and improves image quality.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a camera flicker elimination method and device based on sensor detection. Background technique [0002] There are more and more applications of cameras in cars, such as reversing rear view devices, 360 panoramic surround view devices, streaming media interior rearview mirrors, streaming media exterior rearview mirrors, driving recorders, etc. With the development of autopilot technology, there are increasingly higher requirements for anti-jamming cameras. The intersections of urban roads are full of red street lights and traffic monitoring lights. When a car stops at the intersection or passes slowly, the flickering of the lights will interfere with the imaging of the camera, resulting in ripple-like interference in the video, which in turn leads to a decrease in camera performance. . [0003] The current camera interference suppression solution is only effecti...

Problems solved by technology

The intersections of urban roads are full of red street lights and traffic monitoring lights. When a car stops at the intersection or passes slowly, the flickering of the lights will interfere with the imaging of the camera, resulting in ripple-like interference in the video, which in turn leads to a decrease in camera performance.

[0003] The current camera interference suppression solution is only effective for 50Hz AC lights, but urban street lights generally use LED lights and xenon lights, and the operating frequency ranges from 100 to 200Hz, so it is difficult for the camera to filter out such interference
