ENDOSCOPIC DEVICE

摘要

An endoscopic device that irradiates a plurality of illuminating lights having different spectrums from each other onto a subject at a front edge of an endoscope inserting module and captures the subject to obtain an observation image, includes an illuminating module that generates the plurality of illuminating lights, an imaging module that captures the subject and outputs an image signal of the observation image, a light intensity ratio control module that controls the illuminating module to irradiate the plurality of illuminating lights onto the subject with a set light intensity ratio by setting the light intensity ratio of the plurality of illuminating lights for every observation image, and a color tone correcting module that corrects the color tone of the image signal so as to obtain the observation image with substantially a same color tone even though the light intensity ratio is changed.

1. An endoscopic device that irradiates a plurality of illuminating lights having different spectrums from each other onto a subject at a front edge of an endoscope inserting module and captures the subject to obtain an observation image, comprising:
an illuminating module that generates the plurality of illuminating lights; an imaging module that captures the subject and outputs an image signal of the observation image; a light intensity ratio control module that controls the illuminating module to irradiate the plurality of illuminating lights onto the subject with a set light intensity ratio by setting the light intensity ratio of the plurality of illuminating lights for every observation image; and a color tone correcting module that corrects the color tone of the image signal so as to obtain the observation image with substantially a same color tone even though the light intensity ratio is changed, wherein the light intensity ratio control module obtains a brightness contrast of the observation image and changes the set light intensity ratio to a light intensity ratio such that the brightness contrast becomes a maximum.
