Problems solved by technology

As a result, the endoscope device proposed in Japanese Patent Application Laid-Open No. 2002-095635 has the following problem: in the case of observing with narrow-band light, for example, it is necessary to conduct and suspect a lesion while observing an image of, for example, residue, bile, or intestinal fluid. The image of the bleeding site is roughly the same while observing it, which p

Abstract

An endoscope device is comprised of an illuminating means for projecting first narrow band light with a wavelength band of a blue region and second narrow band light with a wavelength band of a green region to an object in a living body, a photographing means for photographing a first object image in the case that the object is illuminated by the first narrow band light and a second object image in the case that the object is illuminated by the second narrow band light, a memory means for storing the first object image as green and blue components and the second object image as red and blue components, a hue converting means for carrying out prescribed color conversion processing for the red, green and blue components so as to make an image of a prescribed object an image of a prescribed first color other than red.

Description

technical field [0001] The present invention relates to an endoscope device, and more particularly to an endoscope device capable of observing inside a living body based on narrow-band light. Background technique [0002] Conventionally, an endoscope device including an endoscope, a light source device, and the like has been widely used in the medical field and the like. In particular, endoscopic devices in the medical field are mainly used for the observation of living bodies by surgeons and the like. [0003] In addition, as a generally known method of observation using an endoscope device in the medical field, for example, in addition to normal observation, there is also narrow-band light observation (NBI: Narrow Band Imaging). The subject is irradiated with white light, and an image of the subject that is approximately the same as observed with the naked eye can be obtained. In this narrow-band light observation, the subject is irradiated with a frequency band narrower ...
