Zusammenfassung:	Disclosed is a counter which generates a binary code and a digital signal. The counter includes: a reset memory circuit (270) configured to store a sum of N reset binary codes, each of the N reset binary codes corresponding to a result of comparing a reset signal of the pixel signal with the ramp signal, and to calculate one of the N reset binary codes by performing a shifting operation on the sum of the N reset binary codes; and an output memory circuit (280) configured to output the digital signal based on the N reset binary codes, a first image binary code indicating a result of comparing a first image signal of the pixel signal with the ramp signal once, and N sum binary codes, the N sum binary codes respectively indicating N results of comparing a sum signal of the pixel signal with the ramp signal.
