Abstract
In an image pickup device of the present invention, in the case where a mode switchselects a finder mode, a focusing lens is driven at a first speed when a focusing operation is performed in a focus control unit. In the case where the mode switchselects a live view mode, the driving speed of the focusing lens is switched in a range lower than the first speed in accordance with brightness of an object detected by a photometric unitwhen the focusing operation is performed in the focus control unit. With such a configuration, a lens driving control method is changed by AF control of a phase difference detection system and AF control of a hill climbing system, and a driving system suitable for each AF system is performed, whereby the focusing operation can be performed normally at a high speed.
