Abstract
An image sensorA contains a photodiode array portion, a signal processor, a switching instruction partA and a control partA. Each switch SWis provided between the corresponding photodiode PDand the common output line L, and instructed to carry out the switching operation by the switching instruction partA so as to be closed, whereby the charges accumulated in the junction capacitance portion of the photodiode PDare output to the common output line L. On the basis of the instruction from the switching instruction partA, the N switches SWto SWcarry out the switching operation so that the N switches SWto SWare set to the close state in the different periods and the interval at which each switch SWis set to the close state is equal to an integral multiple of a base period. As described above, the charge accumulation time of each of the N photodiodes PDto PDis set to an integral multiple of the base period.
