Abstract
In a monitor camera system includes a monitor camera capable of rotation 360 degrees in pan directions and 180 degrees in tilt directions and a control unit for controlling the monitor camera remotely, the control unit sends control data indicative of a photographing position or photographing direction of the monitor camera to said monitor camera, while the monitor camera receives the control data to calculate, on the basis of the control data, a pan rotation quantity and a tilt rotation quantity by which the monitor camera is to be rotated from the present camera position, thus accomplishing its pan rotation or tilt rotation according to the calculated rotation quantity. Accordingly, with this configuration, an operator can align the monitor camera in a target direction by merely manipulating a joystick in the target direction, that is, can face the monitor camera to a target position through a simple manipulation. Additionally, this configuration makes it unnecessary for the operator to understand the present camera direction.
