UNIT PIXEL OF WIDE DYNAMIC RANGE CMOS IMAGE SENSOR

摘要

PURPOSE: A unit pixel of a wide dynamic range CMOS image sensor is provided to simplify an image processing task without using an additional memory to outside of a pixel array. CONSTITUTION: A unit pixel of a CMOS image sensor comprises a light receiving element, a first floating diffusion region(FD1), a first transistor(M11) for transferring the accumulated electric charge to the first floating diffusion region, a first reset transistor for resetting the first floating diffusion region, a first active transistor for detecting electric property of the first floating diffusion region, and a first addressing transistor for outputting the detection signal to outside.
