ABSTRACT:
An electronic endoscope system has a video-scope, an illumination apparatus, an imaging device, and an image synthesizing processor. The illumination apparatus illuminates a normal light and an excitation-light from the video-scope onto an object. The normal light is reflected off the object, and the excitation-light causes the object to emit fluorescence. The imaging device on the video-scope captures a normal image that is formed by the reflected normal light and a fluorescent image that is formed by the fluorescence. The image synthesizing processor synthesizes the normal image and the fluorescent image into a synthesized image. A color signal of the synthesized image is the same as a color signal of the normal image. A luminance signal or the synthesized image is obtained by mixing a luminance signal of the normal image and a luminance signal of the fluorescent image in a predetermined proportion.
