Abstract
In a video camera apparatus having a camera main-body unit and a lens unit detachably mounted on the camera main-body unit, a state of the lens unit attached to or detached from the camera main-body unit is determined. If the lens unit is not accurately attached to the camera main-body unit, a power supply is controlled and various driving units in the lens unit are disabled or set in a state of low power consumption. At the same time, picture recording is prohibited on the camera main-body unit side, and a nonmounting state of the lens is displayed.
