ENDOSCOPE SYSTEM AND METHOD OF OPERATING ENDOSCOPE SYSTEM

摘要

An endoscope system includes a color image sensor, having pixels sensitive to plural colors different from one another, for imaging an object. Plural LEDs discretely generate light of colors different from one another, to apply polychromatic light constituted by spectrally combining the light of the colors to the object. A light source controller controls the plural LEDs, to correct an intensity ratio of an integrated emission intensity between the plural colors according to receiving the first polychromatic light with respectively the pixels of the plural colors, so that the intensity ratio becomes equal to a target ratio of an integrated emission intensity between the plural colors according to receiving continuous spectrum light with respectively the pixels of the plural colors, the continuous spectrum light having an at least partial wavelength range of light emitted by a white light source.

1. An endoscope system comprising:
a light source apparatus having plural light sources for discretely emitting light of colors different from one another, for generating first polychromatic light having a first polychromatic spectrum by combining light from said plural light sources; an image sensor having pixels of plural colors sensitive to colors different from one another; a light source controller for controlling said plural light sources, to cause an intensity ratio of an integrated emission intensity between said plural colors according to receiving said first polychromatic light with respectively said pixels of said plural colors to become equal to a ratio of an integrated emission intensity between said plural colors according to receiving continuous spectrum light with respectively said pixels of said plural colors, said continuous spectrum light having an at least partial wavelength range of light emitted by a white light source.
