<P>PROBLEM TO BE SOLVED: To provide a solid state imaging device and a driving method of the solid state imaging device capable of realizing a high frame rate without causing deterioration in sensitivity. <P>SOLUTION: In a CMOS image sensor 10 equipped with column parallel ADCs 23-1 to 23-m, addition calculation of a pixel digital value is made over a plurality of lines without adding circuits such as an adder, a line memory, etc., and the realization of a high frame rate is made while maintaining sensitivity to be constant by configuring the column parallel ADCs 23-1 to 23-m using a comparator 31 and an up/down counter 32. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
