LIGHT SOURCE APPARATUS

摘要

A light source apparatus includes: a control section that acquires information relating to a ratio of a light amount value for light with second wavelength band to a light amount value for light with first wavelength band, obtains a light amount value for the light with the first wavelength band so that an observation image has a predetermined brightness, and, from the information relating to the ratio, determines a light amount value for the light with the second wavelength band, and generates light adjustment information for making first and second semiconductor light sources emit light with the light amount value for the light with the first wavelength band and the light amount value for the light with the second wavelength band; and a drive section that, based on the light adjustment information generated by the control section, drives the first and second semiconductor light sources.

1. A light source apparatus comprising:
a first semiconductor light source that emits light with a first wavelength band; a second semiconductor light source that emits light with a second wavelength band that is different from the first wavelength band; a control section that acquires information relating to a ratio of a light amount value for the light with the second wavelength band to a light amount value for the light with the first wavelength band, the information being provided for setting a light amount value for the light with the second wavelength band based on a light amount value for the light with the first wavelength band, obtains a light amount value for the light with the first wavelength band so that an observation image generated by an endoscope for observing a subject to which the light with the first wavelength band and the light with the second wavelength band are applied has a predetermined brightness, and, from the obtained light amount value for the light with the first wavelength band and the information relating to the ratio, determines a light amount value for the light with the second wavelength band relative to the light amount value for the light with the first wavelength band, and generates light adjustment information for making the first semiconductor light source and the second semiconductor light source emit light with the light amount value for the light with the first wavelength band and the light amount value for the light with the second wavelength band; and a drive section that, based on the light adjustment information generated by the control section, drives the first semiconductor light source and the second semiconductor light source.
