This image sensor, in order to carry out a double under - sampling correlated (csdh) of pixels in a matrix of sensors is active pixels (aps)

摘要

Image sensor has a set of pixels arranged in rows and columns. Each column of pixels are attached to two reset data capacitors for storing two reset charges, and two image signal data capacitors for storing two image charges. An averaging circuit carries out averaging operations with the respective reset and image charges to generate an averaged reset and image charge. The averaging operations are performed in an analog domain. An independent claim is also included for a method of sub-sampling pixels in an active pixel sensor (APS) array.
