Abstract: An image device has an array of pixels, each pixel having a photosensitive area, a first storage node and a second storage node. A pixel is illuminated for a first period of time, and charge accumulated on the photosensitive area of the pixel during the first period of time is stored on the first storage node of the pixel. The pixel of the array is illuminated for a second period of time, and charge accumulated on the photosensitive area during the second period of time is stored on the second storage node of the pixel. A first signal is generated based on the charge stored on the first storage node, and a second signal is generated based on the charge stored on the second storage node. The first and second signals are combined using at least one subtraction operation having the first and second signals as operands.

Abstract: 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.
