ELECTRONIC APPARATUS AND METHOD OF CONTROLLING THE SAME

摘要

A digital image processing apparatus and a method of controlling the same are provided. The method of controlling an image plane phase difference digital image processing apparatus, the method includes, in a continuous photographing mode for continuously capturing still images, performing a first focus detection by detecting phase difference of an image captured during a first image capture; performing a second focus detection by detecting phase difference of an image captured during a second image capture; determining moving speed of an object based on results of the first focus detection and the second focus detection; and correcting focus location by driving a focusing lens based on the determined moving speed of the object.

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 based on the determined moving speed of the object.
