Patent ID: 8704940

Claim:
An imaging device comprising: an image pick-up device comprising a plurality of phase difference detection pixel pairs, each formed from a first phase difference detection pixel having an opening eccentrically formed on one side with respect to a main axis of an imaging lens and a second phase difference detection pixel having an opening eccentrically formed on the other side with respect to the main axis, and a plurality of imaging pixel pairs including a plurality of imaging pixels; a reading section that performs read-out with respect to the image pick-up device by reading signals from the imaging pixels and the phase difference detection pixels arrayed in the image pick-up device using a rolling shutter method; a first correlation computation section that performs correlation computation on the signals that have been read from the phase difference detection pixel pairs; a second correlation computation section that performs correlation computation on the signals that have been read from the imaging pixel pairs; a correction section that corrects a correlation computation result from the first correlation computation section using a correlation computation result from the second correlation computation section; and a focusing section that performs focus control using the corrected correlation computation result.
