Patent ID: 8579799

Claim:
An electronic endoscope system comprising: an imaging device for obtaining image signals through imaging an interior of a body cavity at constant intervals; an image producing device for producing images sequentially based on the image signals; a special light projecting device for projecting special light into the body cavity, said special light having a different wavelength range from white light; a biological information acquiring device for acquiring biological information from image signals obtained while said special light is being projected into the body cavity; an associating device for associating the biological information acquired by said biological information acquiring device with an image corresponding to the image signal from which this biological information has been acquired; an input device for inputting biological information on a search target; a search device for searching for an image that is associated with the same biological information as the input biological information on the search target among the images which have been associated with the biological information by said associating device; a display device for displaying images produced by said image producing device; an area designating frame display device for displaying an area designating frame on an image displayed on said display device; and a lock-on device for designating a portion confined in said area designating frame as a search target, wherein said input device inputs the biological information on the designated search target on a basis of biological information acquired from the image signal obtained at the time when the search target is designated.
