Document Type and Number:
Japanese Patent JP4006092
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To control the continuous mobile mechanism of an image pickup means without a strange feeling by decelerating the operation speeds of the image pickup means and a photographing direction moving means when the reception interval of a control instruction signal is long. SOLUTION: The control instruction signal is transmitted by a viewer station 270 at a prescribed interval in order to attain a continuous operation and it is received by a camera station 230. Speed corresponding to the control instruction reception interval is read and operation speed is set. When a radio transmission path is in an excellent state and as the reception interval becomes longer from a time when the most control instruction signals are received, operation speed is decelerated. Then, the operation speed is controlled by a driving pulse period to be given to a motor. Therefore, unnatural movement is evaded at the time of the continuous operation in the control of focusing, zooming and exposure or the like when the control instruction signal is received only once among several times owing to the situation of the radio transmission path or when it cannot be transmitted only at the interval longer than the prescribed one.
