Abstract
A CMOS image sensor includes column-parallel ADCs. Each of the ADCs includes a comparator and an up/down counter. With this configuration, digital values of pixels in a plurality of rows can be added without using additional circuits, such as an adder and a line memory device, and the frame rate can be increased while maintaining constant sensitivity.
