A CMOS image sensor includes a plurality of pixel circuits. Each pixel circuit includes a plurality of transistors. The image sensor includes a controller for controlling operation of the plurality of pixel circuits, wherein the controller is configured to cause at least one of the transistors in each pixel circuit to be placed in an accumulation mode and then switched from the accumulation mode to a strong inversion mode, thereby reducing 1/f noise of the pixel circuits.
