SOLID-STATE IMAGING APPARATUS, AND IMAGING APPARATUS

PROBLEM TO BE SOLVED: To shorten a reset period by suppressing a reset counting error in an A/D converting means. SOLUTION: A solid-state imaging apparatus 1 includes a comparator 16 for comparing a pixel signal obtained by each unit pixel 12 of a pixel array 10 and a reference signal the value of which varies in a stepwise manner, the analog-digital converting means for outputting, as a digital value, the amount of time when the pixel signal and the reference signal change levels by the comparing means, a reset signal generating means 19 for generating a reset signal that triggers a reset operation to be input to the comparator 16 in order to adjust the reference in the analog-digital converting means, and a waveform processing means 20 provided between the reset signal generating means 19 and the comparator 16 for increasing the degree of dullness of a waveform of the reset signal.
