Abstract
A solid-state image device has a photoelectric conversion part and has pixels for focus detection and image pixels that are allocated in a row direction and a column direction, and the solid-state image device includes a vertical image scanning circuit that reads image signals to a horizontal image output circuit via vertical image signal lines, a horizontal image scanning circuit that outputs, in a horizontal direction, image signals of one row read to the horizontal image output circuit, a horizontal scanning circuit for focus detection that reads signals for focus detection to a vertical output circuit for focus detection via horizontal signal lines for focus detection, and a vertical scanning circuit for focus detection that outputs, in a vertical direction, signals for focus detection of one column read to the vertical output circuit for focus detection.
