Patent ID: 8885090

Claim:
An imaging apparatus, comprising: a solid-state imaging device which is provided, on a light receiving surface, with a plurality of sets of first and second phase difference detection pixels each set of the first and second phase difference detection pixels are adjacent to each other and pupil-divided; a dust presence or absence determination unit that determines whether a dust image is present or not in an image captured in an AF region of the light receiving surface; a focus deviation amount calculating unit that calculates a deviation amount between a detection signal of the first phase difference detection pixel and a detection signal of the second phase difference detection pixel overlapping with the dust image when the dust image is included in the AF region; a deviation amount reliability determination unit that judges reliability of the deviation amount; and a control unit that performs an autofocus control by a phase difference AF method using the deviation amount when the reliability of the deviation amount is high and performs an autofocus control by a method other than the phase difference AF method using the deviation amount when the reliability is low, wherein a set of first and second phase difference detection pixels which is positioned on a boundary of the region overlapping with the dust image in the AF region and in which one of the first and second phase difference detection pixels is included in a region which does not overlap with the dust image is excluded from the calculation target of the deviation amount.
