<p>A remote-control device for a camera does not need to consider the adverse effect given by the processing delay time and correct a location of a camera and thus is superior in operativity. The remote-control device for a camera includes an input unit (3) for inputting an operating instruction and data for the overall remote-control device for a camera, a display unit (12) for displaying a received or picked image, a communication line connected to a communication network, a communication device (2) or controlling connection and disconnection of the communication line (1), coding a signal to be sent to the communication line (1), and decoding the received signal, a control unit (6) for controlling the overall remote-control device for a camera by an operating instruction, and an imaging unit (11) for imaging a target object as it is being panned and tilted. The control unit (6) has control section for each operating side (7), start control section (8), stop control section (9) and communication control section (not shown). If the imaging unit (11) of the calling side is handled on its side, the control section (7) activates the control unit (6) of this side to output a cycle exciting pulse train. If the imaging unit (11) of the calling side is handled from the other side, the control section (7) activates the control unit (6) of the calling side to output a long-cycle exciting pulse train. The start control section (8) operates to output a long-period exciting pulse train for a fixed interval at the initial start of panning and tilting the imaging unit (11). After the passage of the fixed interval, the start control section (8) operates to gradually reduce the cycle of the exciting pulse train to a short fixed cycle. When the panning or the tilting of the imaging unit (11) is stopped, the stop control section (9) operates to output an exciting pulse train for a predetermined interval. The exciting pulse train serves to pan and tilt the imaging unit (11) in the reverse direction to the action before stopping. The communication control section operates to set the cycle of the exciting pulse outputted by the control section for each operating side, the cycle of the exciting pulse train outputted by the stop control section, or the interval outputted thereby according to the processing delay time. <MATH></p> |
