Abstract

A solid-state imaging apparatus including: a pixel section having pixels two-dimensionally arranged into row direction and column direction, each pixel containing a photoelectric conversion section, an accumulation section for accumulating output of the photoelectric conversion section, an amplification section for amplifying output of the photoelectric conversion section accumulated at the accumulation section and outputting it as pixel signal, and a reset section for effecting reset of the accumulation section; a vertical scanning section for selecting row to be read out of the pixel section; vertical signal lines provided correspondingly to columns of the pixel section, onto which pixel signals of pixels arranged in column direction are outputted; a column amplifier section for effecting suppression of dark current component of the pixels contained in pixel signals inputted through the vertical signal line and for amplifying the pixel signals after the suppression; a horizontal scanning section for selecting the pixel signal amplified by the column amplifier section and outputting it onto a horizontal signal line; and a dark current correction signal generation section for gener…
