PROBLEM TO BE SOLVED: To accurately correct a luminance of a fluorescence image of an observed object with an easy structure. SOLUTION: In one embodiment, an image processor 30 includes a buffer 32 for a white light image, a buffer 33 for a fluorescence image, a uniform image generating section 35, and a correction processing section 36. The buffer 32 for white light image memorizes a white light image photographed by a white light imaging section 26 via a color filter group 25. The buffer 33 for the fluorescence image memorizes the fluorescence image photographed by a fluorescence imaging section 28. The uniform image generating section 35 extracts each picture signal of the white light image corresponding to a predetermined color filter for transmitting a light of a wavelength band where the light absorption characteristic of a contrast region in the observed region 100 among the color filter group 25 becomes low, and generates the uniform image based on each extracted picture signal. The correction processing section 36 corrects the fluorescence image in the buffer 33 for the fluorescence image by the uniform image. COPYRIGHT: (C)2011,JPO&INPIT |
