摘要： PROBLEM TO BE SOLVED: To achieve fast AD conversion and power consumption reduction in a configuration such that charge transfer and signal output are carried out divisionally, when all accumulated charges cannot be output through a single read. SOLUTION: A solid-state imaging device which performs the charge transfer and signal output divisionally when all the accumulated charges in a photoelectric conversion unit can not be output through a single read performs AD conversion of respective output signals obtained through (n)-divisional transfer with different conversion precision. For example, when accumulated charges are not many, all the accumulated charges can be read out through first divisional transfer, so the conversion precision of the AD conversion is gradually decreased according to the readout order.
