Patent ID: 7528872

Claim:
A solid-state imager apparatus comprising: a pixel portion in which a plurality of pixel cells respectively having functions of converting an incident light into an electrical signal are arranged in a matrix; a row unit reset unit which resets the pixel cells of the pixel portion in units of rows when the imager apparatus shoots a moving image; a simultaneous reset unit which resets all of the pixel cells of the pixel portion simultaneously when the imager apparatus shoots a still image, wherein a reset action in units of rows at the row unit reset unit and a simultaneous reset action at the simultaneous reset unit are selectively executed in accordance with whether the shot image is a moving image or a still image, and; a vertical scanning circuit to scan rows to be read of the pixel portion, an electronic shutter scanning circuit to determine a timing of an exposure operation when a light is made to be incident to each pixel cell, and a multiplexer to output one of an output of the vertical scanning circuit and an output of the electronic shutter scanning circuit to the pixel portion, wherein the simultaneous reset unit is configured by a part of the multiplexer, wherein the multiplexer is configured by: a reading output circuit comprising a transistor to fetch outputs of the vertical scanning circuit, a capacitance to accumulate reading row selection signals, and a reading output transistor; an electronic shutter output circuit comprising a transistor to fetch outputs of the electronic shutter scanning circuit, a capacitance to accumulate electronic shutter row selection signals, and an electronic shutter output transistor; and a simultaneous reset signal fetching transistor in which a source is connected to a connection between the transistor to fetch outputs of the electronic shutter scanning circuit and the capacitance to accumulate the electronic shutter row selection signals, and which has a gate to which a simultaneous reset pulse is inputted, and a drain connected to a simultaneous reset power supply, and an output line of the reading output circuit and an output line of the electronic shutter output circuit are in common.
