<P>PROBLEM TO BE SOLVED: To provide an endoscope diagnostic apparatus which takes an image of autofluorescence having weak optical power at a high S/N ratio. <P>SOLUTION: The endoscope diagnostic apparatus includes: a light source LD emitting exciting light with a prescribed wavelength and making a plurality of autofluorescence simultaneously emit; a turret 74 having a primary filter through which primary light including the emission wavelength range of a target autofluorescence is transmitted, and a secondary filter through which secondary light within the wavelength range of the primary light and not including the emission wavelength range of the target autofluorescence is transmitted; image elements 58B taking images of the primary and secondary autofluorescent synthetic light simultaneously emitted by irradiating a subject person with the exciting light and divided into spectrum with the primary and secondary filters to obtain the images of the primary and secondary autofluorescence; and an image processing part 70 which adjusts an effective amount of exposed light received with the pixels of the image elements respectively through the primary and secondary filters when taking the image of the synthetic light, subjects the primary and secondary autofluorescent images to image processing, extracts the target autofluorescent image corresponding to the target autofluorescence and displays the images on a display device. <P>COPYRIGHT: (C)2013,JPO&INPIT |
