The CCU 307 is connected to a motion detection device 308 that detects a motion of an endoscopic image and a red detection device 309 that detects a red signal component included in a video signal, and outputs a video signal to these. ing. The image motion detection signal 310 and the red color detection signal 311 generated by these devices are supplied to the controller 312.

Further, the endoscope 301 is provided with a scope switch 313 for instructing freeze, release and the like, and an operation knob 314 for performing bending operation and the like. A potentiometer 315 is connected to the operation knob 314,
The output signal of the potentiometer 315 is supplied to the operation knob movement detection device 316. The operation knob movement detection device 316 is connected to the controller 312, and the operation knob movement signal 317 generated by the operation knob movement detection device 316 is input.

The structure of the operation knob movement detecting device 316 is shown in FIG. The operation knob movement detection device 316 includes a retriggerable one-shot 331 and a buffer 332, and the time constant of the retriggerable one-shot 331 is set to, for example, 10 seconds. Therefore, if the operation knob 314 is operated within 10 seconds, a pulse is input to the retriggerable one shot 331 and this output is “H”.
Then, the operation knob movement signal 317 becomes "H". On the other hand, if the operation knob 314 is not operated for 10 seconds or more, the output of the retriggerable one-shot 331 becomes "L", and the operation knob movement detection signal 317 becomes "L". The controller 312 can determine whether or not the endoscope 301 is being operated based on the level of the operation knob movement detection signal 317.

Next, the operation of the red color detection device 309 will be described with reference to FIGS. 13 and 14. Red detector 3

Of the RGB signals of the video signal output from the CCU 307, the R signal is clamped by the clamp circuit 333. Then, the comparator 334 determines whether or not the output of the clamp circuit 333 is equal to or higher than the reference voltage Vr.

At this time, the retriggerable one shot 33
If the time constant of 5 is set to 1/60 seconds or more,
As shown in (a), when the red signal is sufficient (that is, it is considered that the endoscope 301 is used in the living body at this time), that is, when the R signal is Vr or more, the red detection signal. 311 becomes “H”. On the other hand, when the red signal is small as shown in (b), the red detection signal 311 becomes "L" because it is Vr or less.

The motion detecting device 308 detects a general motion of an image by, for example, detecting a motion vector from an image signal. When the motion of the image is detected, the image motion detection signal 310 is " H ". or,
In the case of an image having no motion, the image motion detection signal 310 becomes "L".

The scope switch movement detecting device 318
The operation knob movement detection device 316 shown in FIG. 12 has substantially the same configuration, and detects whether or not the scope switch 313 has been operated and outputs a scope switch movement detection signal 319. Here, the time constant of the retriggerable one shot is set to a value slightly longer than that of the operation knob movement detection device 316, for example, about 30 seconds.

If any of the operation knob movement detection signal 317, the image movement detection signal 310, the red detection signal 311, and the scope switch movement detection signal 319 is "H", the controller 312 is in use by the endoscope 301. It is determined that there is, and the dimming signal 320 is set to "L". Dimming signal 320
Is “L”, the light source lamp 32 in the light source device 304
2 emits light with a normal light amount. On the other hand, if all the four detection signals are "L", it is determined that the endoscope 301 is not used and the dimming signal 320 is set to "H". When the dimming signal 320 becomes “H”, the light emission amount of the light source lamp 322 is reduced.

In this way, the red signal component, the movement of the image,
The endoscope is not in use because it detects movements of operating members such as switches to determine whether the endoscope is used or not, and reduces the light amount of the light source when it is not in use. At this time, it is possible to prevent unnecessary current from flowing through the light source lamp, which can extend the life of the light source lamp. It also saves energy. Further, since the light is not turned off during non-inspection, the number of times of turning on / off can be reduced, and the consumption of the lamp due to the load at the time of lighting can be prevented, so that the life can be further extended.

In the present embodiment, the dimming signal is set to "H" when all four detection signals are "L". However, the present invention is not limited to this, and any two of the four detection signals can be used. The dimming signal may be set to "H" when three or three or one detection signal becomes "L". Further, when the four detection signals are "L" for a certain period of time (for example, 5 seconds) or more, the dimming signal is set to "H", and the detection signals are temporally monitored to determine the inspection / non-inspection. May be.

By the way, when operating an existing endoscope device such as a light source device from the controller, it is necessary to add a circuit or a port for changing the signal flow to change the software. The interface between the controller and the controller may be simply performed by using the circuit of the device operation unit.

FIG. 15 shows the case of the controller direct control system. The input / output parallel port (or expansion slot) 152 of the controller 151 including a personal computer or the like is connected to the input control unit 154 and the output control unit 155 of the panel interface 153.
