Abstract
In a monitor camera system capable of understanding a direction, a monitor camera follows, through a picture taken by the monitor camera, the monitor camera makes 360-degree pan rotation and 180-degree tilt rotation, and generates image data in which a character representative of a photographing direction (for example, north) of the monitor camera is superimposed on a picture taken by the monitor camera. Accordingly, the monitor camera provides a picture in which the photographing direction indicating character appears. This enables an operator to easily understand the camera direction through the monitor picture, thus achieving efficient and accurate camera manipulation.
