Abstract:
A solid-state image capturing apparatus according to the present invention includes a pixel area in which pixels for generating a signal charge by a photoelectric conversion on an incident light are arranged in a two dimensional matrix; a row selection section for selecting each pixel row of the pixel area; a plurality of column signal lines, to which an analog pixel signal from each pixel of a pixel row selected by the row selection section is readout; and a signal processing circuit for generating a digital pixel value from the analog pixel signal of each pixel that is read out to each of the column signal lines, where the signal processing circuit includes at least two or more AD conversion circuits for simultaneously converting the analog pixel signal of each pixel of the selected pixel row into a digital pixel value.
