Claim:
1. A digital image processing apparatus comprising: an imaging lens comprising a focusing lens; a lens driving unit that drives the focusing lens; an imaging device comprising imaging pixels for capturing a light transmitted through the focusing lens and generating image signals, and phase difference detecting pixels for detecting phase difference of a captured image; and a control unit that controls the phase difference detecting pixels to perform focus detection by detecting phase difference of a live-view image while the live-view image is output from the imaging pixels, wherein, in a continuous photographing mode for continuously capturing still images, the control unit comprises: a first calculation unit that performs a first focus detection by detecting phase difference of a still image captured during a first image capture operation; a second calculation unit that performs a second focus detection by detecting phase difference of a still image captured during a second image capture operation; a moving speed determining unit that determines moving speed of an object based on results of the first focus detection and the second focus detection; and a focus location correcting unit that corrects focus location by driving the focusing lens within a preset time period based on the determined moving speed of the object.
