Abstract
In a camera unit that is capable of attaching and detaching a lens unit, a camera control unit transmits a drive command for shifting a focus lens to a position corresponding to a focal point detected by use of an evaluation value for focus adjustment generated from an imaging signal by a TVAF signal processing unit to a lens control unit. The camera control unit acquires data indicating the amount of change in image magnification from the lens apparatus when performing center shift to thereby control the focus lens so as to suppress an out-of-focus blur of an image according to the image signal in response to the amount of change in image magnification relative to the shift amount of the focus lens in the vicinity of a focal point.
