Solid-state imaging apparatus

Abstract

A solid-state imaging apparatus including: a pixel section having a plurality of pixels two-dimensionally arranged into a matrix, each pixel containing a photoelectric conversion section for converting an incident light into signal electric charges, an accumulation section for accumulating the signal electric charges, a transfer section for transferring the signal electric charges to the accumulation section, an amplification section for amplifying and outputting as pixel signal the signal electric charges accumulated at the accumulation section, and a reset section for resetting the accumulation section by supplying an electric potential retained on a power supply line to the accumulation section, the pixel section having output signal lines provided column by column onto which the pixel signal is outputted, connected to the other end of a constant current supply having one end grounded; and a control section where, of a first one of the pixels and a second one of the pixels connected to the same one output signal line, taking the first pixel as one of the pixels subject to reading of pixel signal conforming to the incident light and the second pixel as non-subject one of the pixels set in accordance with a location of the first pixel, an output from the second pixel onto the output signal line is used at the time of outputting of the pixel signal from the first pixel onto the output signal line to effect control so that an electric potential difference between the one end and the other end of the constant current supply is kept in a range where the constant current supply is operable.
