Abstract
When the start of still picture AF operation is designated during moving picture pick-up/recording, the current position of an AF lens is acquired, and the AF lens is moved by X addresses from the lens position. The AF lens is moved to the Yth address in an opposite direction from the lens position to which the AF lens has been moved by X addresses, and an AF evaluation value is detected for each address. Whether the peak value of the AF evaluation value has been detected is determined. If so, whether the peak value is larger than the threshold is determined. If the peak value is determined larger, the AF lens is-moved to a lens position at which the peak value has been obtained. Hence, still picture AF operation can be performed within a short time during moving picture pick-up/recording.
