Abstract
Official abstract text for this publication.
A flicker compensation method for images taken by an image sensor operating in rolling-shutter mode may include capturing a first image and capturing a second image offset in time from the first image by an integer or zero number of flicker periods, plus half a flicker period. The method may also include producing a compensated image based on an average of the first and second images.
First claim
Opening claim text (preview).
What is claimed is: 1. A flicker compensation method for images acquired by an image sensor operating in rolling-shutter mode, the method comprising: capturing a first image; capturing a second image offset in time from the first image by an integer or zero number of flicker periods, plus half a flicker period, the first and second images having different exposure times associated therewith, and the offset in time being between respective centers of the different exposure times…
