Abstract
A digital camera comprises an imaging/focus detection element, in which focus detection pixel rows are incorporated in a two-dimensional array of a plurality of imaging pixels, that outputs image signals and focus detection signals, a focus detection unit that detects a state of focal adjustment at a photographic optical system based upon the focus detection signal, an image blur detection unit that detects an image blur quantity, a reliability judgment unit that judges, based upon the blur quantity, whether or not the state of focal adjustment detected in correspondence to a focus detection pixel row disposed along a direction different from a rolling shutter scanning direction among the focus detection pixel rows is reliable, and a focal adjustment unit that executes focal adjustment for the photographic optical system based upon the state of focal adjustment judged to be reliable by the reliability judgment unit.
