In response to the user's short press of one preset button, a video camera according to one aspect of the invention reads out preset values stored in an EEPROM and adjusts the pan position, the tilt position, the position of a zoom lens, the position of a focus lens based on the read-out preset values. A movable range of the focus lens is restricted to a specific limited range between a closer direction end and a background position as a previously focused position. Hill-climbing control is then performed in this restricted movable range. This arrangement effectively ensures quick adjustment of the focus position of the video camera.
