With such a configuration, in the image pickup device 6, the exposure time is measured by the exposure photometry unit, and the shutter time is set according to the exposure time. Along with this, the color temperature measuring unit measures the color temperature according to the brightness of the observation target, and the color temperature signal is transmitted to the color temperature display 21 of the control box 20 through the cable. Thereby, the color temperature is displayed on the color temperature indicator 21.

When the lamp voltage setting device 22 is operated in this state, the voltage value supplied to the lamp of the light source device 7 changes, and the brightness of the observation target changes. When the brightness of the observation target changes in this way, the color temperature displayed on the color temperature indicator 21 changes accordingly.

Therefore, the color temperature can be easily set to a desired value by operating the lamp voltage setting device 22 provided side by side with the color temperature display 21 while looking at the color temperature display 21.

The exposure compensation display 24 and the exposure compensation setting knob 25 are connected to the exposure metering section of the imaging device 6 via a signal line, and are set by the exposure metering section by operating the exposure compensation setting knob 25. The exposure time is adjusted. The exposure correction indicator 23 displays the exposure correction amount corrected by the exposure correction setting knob 25. With such a configuration, the color temperature can be easily set to a desired value by operating the lamp voltage setter 22 while looking at the color temperature indicator 21 as in the above.

On the other hand, the exposure metering unit of the image pickup device 6 sets the exposure time for the observation target. When the exposure correction setting knob 25 is operated in this state, the exposure time set by the exposure metering unit is corrected according to this operation amount. At this time, the exposure correction indicator 24 displays the exposure correction amount corrected by the exposure correction setting knob 25. Therefore, the desired exposure time can be corrected while observing the exposure correction amount displayed on the exposure correction display 24 to obtain the desired color photograph.

As described above, in the second embodiment, since the control box 20 is provided with the color temperature display 21 and the lamp voltage setting device 22, the exposure correction display 24 and the exposure correction setting knob 25 are provided. It is possible to obtain a desired color by setting the color temperature, and then correct the desired exposure time while observing the amount of exposure correction to obtain a color photograph of the desired shade.
