の範囲第１項記載の物体観測装置。[Claims for Utility Model Registration] A device that separates and extracts a primary reflected image from a reflected image obtained by irradiating light onto an observation object, for irradiating a mixture of light of different wavelengths onto the observation object. a light source section; an imaging section having an imaging device in which pixels sensitive to light of each of the wavelengths are alternately arranged two-dimensionally; and a reflected image of the light of each of the wavelengths is captured from the imaging section, and the brightness of each reflected image is determined. An object observation device comprising: an image processing section that separates a reflected image into a primary reflected image and a secondary reflected image based on the ratio of the reflected images, and extracts the primary reflected image. The light source section is comprised of a plurality of light sources that emit light of different wavelengths and an optical system that irradiates the light from each light source to the observation target with a common optical axis. Object observation device. An imaging device is a practical imaging device that is formed by alternately arranging band-pass filters that pass light of each wavelength on an imaging surface formed by two-dimensionally arranging light-receiving elements in a lattice pattern, corresponding to each light-receiving element. An object observation device according to claim 1 of the patent registration claim.
