Color tone controller for endoscope
First Claim
1. A color tone controller for an endoscope having converting means for converting an observed image into an electric signal and monitor means for reproducing an observed image on the basis of said electric signal input thereto, said controller comprising:
- color tone control means for selectively controlling the color tone of the image reproduced by said monitor means independently of the image reproduced by said monitor means, said color tone control means effecting color tone control by changing the intensities of at least two color components among the three primary colors; and
color tone display means for quantitatively displaying on said monitor means the contents of color tone control effected with said tone control means, wherein said color tone display means digitally displays on said monitor means the intensities of the color components which are changeable in the form of numerals.

Abstract
A color tone controller for an endoscope which has a converting device, for example, a solid-state image sensor, for converting an observed image into an electric signal which is delivered to a monitor device where an observed image is reproduced. The color tone of the image reproduced by the monitor device is controllable with a color tone control device. The contents of the color tone control are quantitatively displayed on the screen of the monitor device in the form of numerals by way of example.
