Solid-state imaging apparatus and imaging apparatus

An imaging apparatus comprising:

• comparing means for comparing a pixel signal obtained by a pixel section and a reference signal the value of which varies in a stepwise manner;
• 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;
• reset signal generating means for generating a reset signal that triggers a reset operation to be input to the comparing means in order to adjust the reference in the analog-digital converting means;
• waveform processing means provided between the reset signal generating means and the comparing means for increasing the degree of dullness of a waveform of the reset signal;
• and
• control means for controlling at least the analog-digital converting means and the reset signal generating means.
