Patent ID: 7397503

Claim:
A system for reducing artifacts caused by illuminant flicker, said system comprising: an image sensor comprising an array of pixel circuits arranged in rows, a first of the pixel circuits being located in a first of the rows, a second of the pixel circuits being located in a second of the rows, the first of the pixel circuits being operable to acquire first information corresponding to the scene at a first time, the second of the pixel circuits being operable to acquire second information corresponding to the scene at a second time subsequent to the first time and to acquire third information corresponding to the scene at a third time subsequent to the second time, the first of the pixel circuits being further operable to acquire fourth information corresponding to the scene at a fourth time subsequent to the third time; the image sensor being operable to combine the first information and the fourth information to provide a first output signal corresponding to the first of the pixel circuits, and to combine the second information and the third information to provide a second output signal corresponding to the second of the pixel circuits.
