  • Publication number: 20220353427
    Abstract: A control apparatus includes at least one processor and at least one memory storing instructions that, when executed by the at least one processor, cause the at least one processor to function as a setting unit and a selection unit. The setting unit is configured to set an object area indicating an object by using object information that includes information on a part of the object and is based on an image signal converted from an object image and to set a plurality of focus detection points by using the object area. The selection unit is configured to select, from the plurality of focus detection points in a selection area, a main focus detection point on which focusing is performed. In a case where the object is a vehicle, the selection unit makes the selection area narrower than the object area.

  • Patent number: 10447914
    Abstract: An imaging apparatus, to which a lens apparatus can be attached, includes an imaging unit that executes charge accumulation in synchronization with a reference signal and generates an imaging signal, a control unit that controls the data communication with an attached lens apparatus and executes focus detection by using data received from the lens apparatus. The control unit executes data communication with the lens apparatus in a first communication mode in which predetermined data is periodically communicated in synchronization with the reference signal. When a predetermined operation that instructs preparation for still image shooting is being carried out by a user, the control unit changes the first communication mode to a second communication mode in which the control unit executes data communication with the lens apparatus out of synchronization with the reference signal.
