PURPOSE:To obtain a color hard copy with stable picture quality, by inputting peak voltage values of a video signal by colors to a cathode-ray tube and adjusting them to reference voltage values through voltage adjusting means. CONSTITUTION:Under the control of a timing controller 10, color video signals which arrive are changed over repeatedly by a video signal switch 1 in the order of R, G, and B. A voltage adjusting dial 21a is adjusted to set a peak voltage value detected by a peak detecting means 22 to the reference voltage of a reference voltage generator incorporated in a display means 21. This adjustment is made over a look at the display on the display means 23. After the voltage of the video signal is adjusted by the voltage adjusting means 21, switching to operation mode is performed and under the control of the timing controller 10, the screen of a CRT monitor 2 is photographed with an instantaneous color film 8 to obtain a color-balanced hard copy. |
