1. An endoscope apparatus, comprising:
- an optical endoscope composed of;
an elongate inserting section,a light guide inserted into said inserting section and adapted to transmit a light beam applied to an incidence end surface and give it off through an outlet end surface, an objective optical system adapted to form the image of a subject illuminated, andan image guide adapted to transmit the image obtained by said objective optical system to the side of an eyepiece;
a television camera composed of;
a lens adapted to form the image transmitted by said image guide, anda solid image pickup element arranged at the position where the image forming is effected by said lens and equipped with a photoelectric transformation function;
a light source means adapted to supply illuminating light to the incidence end surface of said light guide;
an image signal processing means composed of;
a color image signal generating means adapted to generate predetermined color image signals by performing signal-processing with respect to said solid image pickup element, anda specific-wavelength-region-image signal generating means equipped with output terminals adapted to emit image signals based exclusively on specific wavelength region components in the visible region for generating said color image signals; and
a display means composed of;
a color image display section adapted to display said color image signals, anda specific-wavelength-image-dislay section adapted to display said image signals based exclusively on specific wavelength region components.

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.
