Abstract
A solid-state imaging apparatus including: a pixel section having a plurality of pixels two-dimensionally arranged in rows and columns; a vertical scanning section; a noise suppressing section having clamp capacitors each connected at one end thereof to output ends of the pixels and a mixing switch for connecting in parallel a plurality of the clamp capacitors in the row direction, for effecting noise suppression of signal associated with the pixel; a horizontal scanning section for outputting those signals associated with the pixels after the noise suppression; and a mode control section having in a selective manner a first mode where the noise suppressing section is caused to execute the noise suppression with the mixing switch turned OFF, and a second mode where the noise suppressing section is caused to execute the noise suppression with the mixing switch turned ON after a turning OFF of the clamp setting signal.
