Abstract
Aspects describe front-end pixel fixed pattern noise correction in imaging arrays having wide dynamic range. A photosensor of a first pixel in a first row of an array is reset and a first reset level of the first pixel is measured. The array comprises a plurality of pixels arranged in rows and columns. In response to a result of the first reset level, a reset bus is altered. A feed-forward adjustment of the photosensor of the first pixel is performed to substantially remove fixed-pattern noise. An external readout from the photosensor can occur with substantially all the fixed-pattern noise removed. In some aspects, the adjustment is performed by a switched capacitor block.
