Zusammenfassung:PURPOSE:To enable exact correction by correcting the over controlled quantity of the direction, zoom or focus of a monitor camera generated by transmission delay or signal processing delay corresponding to an image information compressing method with a point to be monitored designated. CONSTITUTION:The operator of a monitor center observes a display 21 and commands rotation stop to an operation part 22 a point of the time when a monitor camera 11 displays an image at a target spot A. An electric pan head 12 reaches a direction B by delay time at such a time. The delay time is a total of the image encoding processing time at an image transmitting terminal 10, the time of image data transmission between the image transmitting terminal 10 and an image receiving terminal 20 and image decoding processing time at the terminal 20 or the like and is made different depending on the image information compressing method. Then, the terminal 10 selects delay information corresponding to the image information compressing method under selection at present, and the correcting rotation is stopped by sending a rotation stop control signal to the pan head 12 after the lapse of rotation correcting time corresponding to this information. The zoom/focus adjustment of the monitor camera 11 is similarly corrected as well.
