UNIT PIXEL OF CMOS IMAGE SENSOR WITH WIDE DYNAMIC RANGE AND CMOS IMAGE SENSOR INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a CMOS image sensor with a wide dynamic range.;SOLUTION: An apparatus of the present invention comprises a plurality of pixels constituted of pixels for storing a photo-current accumulation time of a present frame estimated by a light source for a previous frame, and a control means for controlling the light current accumulation time of the present frame in accordance with the stored photo-current accumulation time, and converts an actual image into an electrical signal.;COPYRIGHT: (C)2006,JPO&NCIPI
