Abstract

An endoscope apparatus equipped with a device for generating color image signals for a normal color display from image signals picked up by using a solid image pickup element under an illuminating device covering the visible light region, and output terminals adapted to output those image signals which are exclusively based on specific wavelength components, the endoscope apparatus allowing a monochrome image with respect to a specific wavelength region to be displayed along with a normal color image.
