Abstract
A signal processing circuit includes: a reference signal generating circuit that generates a reference signal of a ramp waveform of which a voltage value varies with the lapse of time by changing a current; and a signal processing unit including a plurality of processing sections that process the reference signal as a ramp wave and a potential of a supplied analog signal, wherein the reference signal processing circuit has a function of adjusting an offset of the reference signal by adjusting the current from the time of starting the generation of the reference signal or adjusting the level of the reference signal at least at the time of starting the generation of the reference signal.
