Patent ID: 8102463

Claim:
A solid-state image device having a photoelectric conversion part converting an incident light into an electric signal and having focus detection pixels and image pixels which are allocated in a two dimensional matrix in a row direction and a column direction, the solid-state device comprising: an image scanning circuit that reads image signals from said image pixels to an image output circuit via image signal lines and that outputs the image signals read to said image output circuit; and a focus detection scanning circuit that reads focus detection signals from said focus detection pixels to a focus detection output circuit via focus detection signal lines, and that outputs the focus detection signals read to said focus detection output circuit, wherein the solid-state image device independently performs an operation in which said image scanning circuit reads out the signals of said image pixels to said image output circuit, and an operation in which said focus detection scanning circuit reads out the signals or said for focus detection pixels to said focus detection output circuit, wherein: said image scanning circuit includes a vertical image scanning circuit which selects a row including said image pixels and reads the image signals from said image pixels to a horizontal image output circuit via vertical image signal lines, and a horizontal image scanning circuit which outputs in a horizontal direction the image signals of one row read to said horizontal image output circuit; and said focus detection scanning circuit includes a horizontal focus detection scanning circuit that selects a column including said focus detection pixels and reads the focus detection signals from said focus detection pixels to a vertical focus detection output circuit via horizontal focus detection signal lines, and a vertical focus detection scanning circuit which outputs the focus detection signals in a vertical direction of one column read to said vertical focus detection output circuit, in which an operation of reading out the signals of said image pixels to said horizontal image output circuit by said vertical image scanning circuit and an operation of reading out the signals of said focus detection pixels to said vertical focus detection output circuit by said horizontal focus detection scanning circuit are performed independently.
