AI Technical Summary

Benefits of technology

This technology helps analyze captured video data from cameras or other devices without having them move around during capturing time. It uses an analysis process called histogramming to determine how long each pixel was exposed before being counted down into different colors. By analyzing these patterns over multiple frames, it becomes possible to identify specific areas where there may occur shaking movements caused due to movement across objects such as trees or buildings. These techniques help improve accuracy when processing videos while reducing their overall computationally complex nature compared to previous methods like averaging or linear regression.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency and precision of identifying flip-flop patterns in video signals obtained from capturing images without affecting their quality due to movement during processing.

Abstract

The invention provides a method for detecting image flicker stripes and a method for adjusting image exposure time. The method for detecting the image flicker stripes comprises: S110, collecting N continuous image sequences, N being an integer larger than 1, S120, executing a flicker frequency determining step on each frame of image in the N continuous image sequences, and the flicker frequency determining step comprises: S121, obtaining a brightness channel image of a current frame; S122, calculating a line mean vector of the adjacent frame images; S123, calculating a row difference vector; S124, calculating an average value of the row difference vector to serve as an amplitude center of a waveform of the row difference vector of the current frame image; S125, determining a position vector Pose (m); S126, determining at least one predetermined flickering frequency from the predetermined flickering frequency set as the flickering frequency of the current frame of image; and S130, determining the flicker frequency according to the proportion of each predetermined flicker frequency in the predetermined flicker frequency set in the N frames of image sequences. According to the method,the existence and the frequency of flickering in the image frame sequence can be efficiently and accurately detected.
