Imaging apparatus and imaging method

摘要

An imaging apparatus includes: a solid-state imaging device having pairs of phase-difference pixels for detecting a phase difference; a position control section which changes the relative position of an imaging optical system and the solid-state imaging device; a control section which causes the solid-state imaging device to perform plural provisional imagings while changing the relative position; and a regular-imaging position determination section which determines one of the relative positions that are obtained when the provisional imagings are performed, as a relative position in regular imaging, on the basis of, among plural captured image signals which are obtained in the provisional imagings, output signals which correspond to a part or all of the pairs included in the solid-state imaging device, and which are obtained from pixels in areas including the pairs.

1. An imaging method using a solid-state imaging device having pixels which include at least one pair of phase-difference pixels, and which are two-dimensionally arranged, wherein the method comprises:
a position changing step of changing a relative position of the imaging optical system and the solid-state imaging device in a direction perpendicular to an optical axis of the imaging optical system; a provisional-imaging controlling step of causing the solid-state imaging device to perform provisional imaging a plurality of times while changing the relative position; a relative position determining step of determining one of the relative positions that are obtained when the plurality of provisional imagings are performed, as a relative position in regular imaging, on the basis of, among a plurality of captured image signals which are output from the solid-state imaging device in the plurality of provisional imagings, output signals which correspond to a part or all of the pairs included in the solid-state imaging device, and which are obtained from pixels in areas including the pairs; and a regular-imaging controlling step of causing the solid-state imaging device to perform regular imaging in the relative position that is determined in the relative position determining.
