A solid-state imaging apparatus includes a comparator for comparing a pixel signal obtained by a pixel section and a reference signal the value of which varies in a stepwise manner, an analog-digital converter for outputting, as a digital value, the amount of time when the pixel signal and the reference signal change levels by the comparator; a reset signal generator for generating a reset signal that triggers a reset operation to be input to the comparator in order to adjust the reference in the analog-digital converter, and a waveform processor provided between the reset signal generator and the comparator for increasing the degree of dullness of a waveform of the reset signal.
