Abstract:
An imaging apparatus includes: a pixel configured to generate a signal through photoelectric conversion; a comparator configured to compare a signal generated by the pixel with a first reference signal that changes with time; and a control unit configured to change the rate of change of the first reference signal with respect to time according to a comparison result of the comparator.
