摘要： In a camera unit that is mountable to a lens unit having a focus lens, an AF signal processing unit generates an AF evaluation value from an imaging signal obtained by an imaging element, and a camera control unit generates drive information for moving the focus lens to an in-focus point using the AF evaluation value and transmits the drive information to the mounted lens unit. The camera control unit transmits drive information including a focus lens position served as a reference for micro vibration and an amount of movement of the focus lens indicated by shift amount of an image plane with reference to the focus lens position to a lens unit.

摘要： A focus detection apparatus detects a first subject region (e.g., face region) from an image signal, detects a second subject region (e.g., human body region), in which the first subject region can be estimated, from the image signal, and performs focus detection based on an image signal corresponding to the set focus detection area. In the case where the primary subject corresponds to the first subject region detected, the focus detection area is set to a first region, and, in the case where the primary subject corresponds to the first subject region estimated based on the second subject region, the focus detection area is set to a second region that is larger than the first region.

摘要： 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.
