Claims

[Claims for Utility Model Registration] At least one for photographing the entire image of the subject
At least one fixed camera with a constant imaging direction, and at least one camera with a zoom function and a pan tilt head for photographing only a certain part of the subject.
three or more movable cameras, a potentiometer that is separately provided on the pantil head of each movable camera and detects the horizontal and vertical positions of the pantil head, and a video signal is separately supplied from the fixed camera to each fixed camera; a first monitor device of the same number as the fixed cameras that individually reproduces images taken by the cameras; a second monitor device to which a video signal is supplied from the movable camera and reproduces the images taken by the movable camera; a horizontal sawtooth wave generation circuit to which a horizontal drive pulse is supplied from one of the fixed cameras; a horizontal sawtooth wave generation circuit to which a horizontal position detection signal is supplied from one of the potentiometers; a first equivalency detection circuit to which a sawtooth wave having a level corresponding to the one fixed camera and having a period of one horizontal scanning period is supplied from the generating circuit; and a vertical sawtooth wave to which the vertical drive pulse is supplied from the one fixed camera. a wave generating circuit; the vertical sawtooth wave generating circuit supplies a sawtooth wave having a level corresponding to the one fixed camera and having a period of one vertical scanning period; and a vertical position detection signal is supplied from the one potentiometer; a second equivalence detection circuit that is configured to output a signal from the second equivalence detection circuit to a second pulse width determination circuit; a multiplier for providing a position indication signal to the first monitoring device connected to the one fixed camera; An image input/output device comprising position display circuits provided separately between the two.
