PROBLEM TO BE SOLVED: To realize an image processor for fluorescent observation for obtaining an image in which a normal tissue is easily recognized from a lesioned tissue by simple constitution. SOLUTION: This image processor 4A comprises an image processing circuit 38 which assigns an image signal on a long wavelength side (a wavelength band including a non-absorption band of light of hemoglobin) of reflected light to a B channel of RGB channel, an image signal of a fluorescent image to a G channel, and an image signal on a short wavelength side (a wavelength band including an absorption band of light of hemoglobin) of the reflected light to an R channel, synthesizes them to be a single image to form a synthetic image, and which adjusts the gains of the three input image signals so that a boundary of hues of the normal tissue and the lesioned hue displayed on the synthetic image may be included in a range surrounded by four dots of (0.21, 0.53), (0.18, 0.50), (o.23, 0.44) and (o.25, 0.49) with respect to CIE 1976 UCS chromaticity diagram.
