Patent ID: 8031259

Claim:
A solid-state imaging device, comprising: a plurality of pixels disposed in a two-dimensional array; a scanning circuit that selects a specific pixel among the pixels by selecting a pixel row and a pixel column; and a signal output circuit that outputs a signal from the pixel selected by the scanning circuit, wherein: the plurality of pixels include a plurality of first focus detection pixels at each of which a light flux having passed through a first area of an exit pupil of an imaging optical system is received and a plurality of second focus detection pixels at each of which a light flux having passed through a second area of the exit pupil of the imaging optical system, different from the first area, is received, both used as focus detection pixels that output signals to be used to detect a focusing condition of the imaging optical system; the first focus detection pixels and the second focus detection pixels are disposed within a single row or a single column; the scanning circuit selects a plurality of first focus detection pixels disposed within the single row or column at once and a plurality of second focus detection pixels disposed within the single row or column at once; and the signal output circuit combines signals from the plurality of first focus detection pixels selected by the scanning circuit and outputs a resulting composite signal, and also combines signals from the plurality of second focus detection pixels selected by the scanning circuit and outputs a resulting composite signal.
