ABSTRACT:
An image inputting device for an endoscope is provided in which image obtained by the endoscope and decomposed into a plurality of color signals is converted into electrical signals. A gray scale correcting section having an adjustable correcting value is provided for each of the plurality of color signals. In consequence, the gray scales of the plurality of color signals can be separately and adjustably corrected, and a resolution which corresponds to the luminance level of each color can be set so as to enable effective information to be easily obtained from all wavelength regions.
