Abstract
An image sensor including an ADC circuit receiving pixel data to be supplied in parallel from the a pixel array, outputting a reference signal in accordance with a digital code, comparing the reference signal and the pixel data, and outputting the digital code at which the reference signal and the pixel data have a predetermined relation, the ADC circuit including a ramp-signal generating circuit outputting a ramp signal having a gradient with respect to change of the digital code, the gradient being different between when the digital code is in a first range and when the digital code is in a second range different from the first range and an attenuator receiving the ramp signal to be supplied and outputting the reference signal having a gradient being the same between when the digital code is in the first range and when the digital code is in the second range.
