Abstract
A video camera apparatus for a video conference is arranged to detect the zoom level of a zoom lens by a zoom level detecting circuit and to control a motor control circuit according to the result of detection in such a way as to lower the speed of a panning or tilting operation on a video camera accordingly as the position of the zoom lens shifts from a wide-angle position to a telephoto position. In panning or tilting the video camera in a zoom-in state, this arrangement makes the panning or tilting speed lower than the speed of panning or tilting performed in a zoom-back state, so that the movement of objects on a picture displayed on a monitor can be effectively moderated to make the details of the display easily discernible without any unpleasant impression. The arrangement thus facilitates the operation on the video camera.
