ENDOSCOPE APPARATUS

摘要

An endoscope apparatus includes an illuminating section capable of irradiating a subject with a light in a first wavelength band and light in a second wavelength band, an image processing section including a color filter configured by a plurality of filters, the image processing section generating, from two image pickup signals respectively generated in a first pixel and a second pixel that respectively receive light in a predetermined wavelength band and light in a wavelength band different from the predetermined wavelength band among return lights from the subject, first and second image signals, a control section that determines whether the two image pickup signals can be separated into the first and second image signals, and an illumination control section that performs irradiation in a time division manner or simultaneous irradiation according to a determination result whether the separation is possible or not.

1. An endoscope apparatus comprising:
an illuminating section capable of irradiating, as illumination light for illuminating a subject, light in a first wavelength band and light in a second wavelength band having a wavelength band different from the light in the first wavelength band; an image processing section that generates, from an image pickup signal generated in a first pixel that receives light in a predetermined wavelength band among lights from the subject on which the illumination light is irradiated and an image pickup signal generated in a second pixel that receives light in a wavelength band different from the light in the predetermined wavelength band among the lights from the subject, a first image signal and a second image signal respectively allocated to different color channels of a display section for displaying an observation image of the subject; a control section that determines whether an image pickup signal of the subject corresponding to the light in the first wavelength band and an image pickup signal of the subject corresponding to the light in the second wavelength band can be separated into the first image signal and the second image signal; and an illumination control section that simultaneously irradiates, when the control section determines that the image pickup signal of the subject corresponding to the light in the first wavelength band and the image pickup signal of the subject corresponding to the light in the second wavelength band can be separated into the first image signal and the second image signal, the light in the first wavelength band and the light in the second wavelength band and irradiates, in a time division manner, when the control section determines that the image pickup signals cannot be separated into the first image signal and the second image signal, the light in the first wavelength band and the light in the second wavelength band.
