To provide a digital counter, a timing generator, an imaging system, and an imaging apparatus which can reduce the periodic power supply noise, accompanying the counting operation.
The digital counter performing count operation by Gray code and outputting a count consisting of a plurality of bits comprises a first Gray code counter performing count operation by Gray code, in synchronism with a clock signal of first phase and generating a count by Gray code of a part of the plurality of bits, and a second Gray code counter performing count operation by Gray code, in synchronism with a clock signal of second phase different from the first phase and generating a count by Gray code of another part of the plurality of bits.
