Image sensor and imaging apparatus

摘要

An image sensor includes: a plurality of imaging pixels disposed two-dimensionally in rows and columns to capture an image; a plurality of first focus detection pixels for focus detection and a plurality of second focus detection pixels for focus detection being disposed in a row in place of the imaging pixels; a row selection circuit that selects in turn a row; a column selection circuit that selects in turn a column; and an output circuit that outputs pixel signals from the pixels selected by the column selection circuit, out of the pixels in the rows selected by the row selection circuit, wherein the column selection circuit selects a column according to whether or not the row selected by the row selection circuit includes the first and the second focus detection pixels.
