ABSTRACT:
The present invention provides a novel camera apparatus which can be discretely split into two parts; a lens barrel unit and a lens-barrel-support unit which allows the lens barrel unit to freely turn its direction. A built-in angular rate detector detects a swinging movement of the lens barrel unit, whereas a position detector detects a position relationship between the lens barrel unit and the support unit. An operator unit storing programs controls a drive operation of an actuator that generates a specific amount of torque between the lens barrel unit and the support unit to reduce an output from a system controller unit so that swinging symptom of video picture caused by the swinging movement of the video camera can be eliminated. In addition to this primary function, the operator unit also executes its secondary function, in which the operator unit first detects intention of a camera operator by identifying a varied position relationship between the lens barrel unit and the support unit when one intentionally changes an aimed direction of the video camera and then the operator unit controls the driving of the actuator so that the lens barrel unit can correctly face the aimed direction.
