Abstract
The present invention aims at providing a photodetector which can secure both a good S/N ratio and a high speed. With a photodetector, (K×M×N) photodiodes PDare arranged in M rows and (K×N) columns in a photodetection unit, and processes (electric charge accumulation, CDS, filtering, and A/D conversion) regarding each of the (K×N) photodiodes PD(k=1 to K, n=1 to N) of each row are carried out successively at each time T. Meanwhile, each of an electric charge accumulation operation in an integrating circuit, a CDS operation in a CDS circuit, a filtering operation in a filter circuit, and an A/D conversion operation in an A/D converteris carried out at each time (N×T).
