ABSTRACT:
An electronic endoscope displays the date so as to enable the year, month, and day to be differentiated on a screen when displaying a date together with the object image. The electronic endoscope is provided with, in a processor, a central processing unit (CPU), a real time clock (RTC), a cathode ray tube controller (CRTC) and a character generator read only memory (CG-RORM) and, on the outside, a keyboard and monitor. A date is read from the RTC and a character code corresponding to the year, month, and day to be displayed on the screen of the monitor is read from the CG-ROM at the CRTC. The character code is transmitted as a character signal to the monitor, and the date is displayed on the screen along with the object image, the month being displayed by a green color and the year and day by a white color at this time.
