Abstract
A CMOS image sensor includes a plurality of pixels arranged column and rows in an array; a column circuit for storing reset values and a value after integration; a correlated double sampler which derives an image signal from the reset and the value after integration; and an anti-eclipse circuit physically separately from the column circuit and electrically connected to one or shared between multiple columns of pixels for restoring corrupted column voltage on a column of pixels.
