Method and apparatus for self-calibration and fixed-pattern noise removal in imager integrated circuits |
摘要 |
An architecture for self-calibration and fixed-pattern noise removal in imager chips. The column-to-column fixed pattern noise and/or pixel-to-pixel fixed pattern noise is determined through a self-calibration operation. During operation of the imager chip, when a value of a pixel is read, the read value is compensated with the fixed-pattern noise corresponding to either the column fixed pattern noise corresponding to the column having the pixel from which the value was read or to the pixel fixed pattern noise corresponding to the pixel from which the value was read.
