Title:
THREE-CCD CAMERA
Document Type and Number:
Japanese Patent JP2023075696
Kind Code:
A
Abstract:
To support an output of a clear image of the inside of an object by highly accurately separating visible light and IR light included in light from the object without increasing the size or cost.SOLUTION: A 3-CCD camera comprises: a spectral prism consisting of a first prism for spectrally dispersing first wavelength-band light of incident light from an observation site, a second prism for spectrally dispersing second wavelength-band light, and a third prism for spectrally dispersing third wavelength-band light; a first image sensor for capturing an image of light entering from the first prism, a second image sensor for capturing an image of light entering from the second prism, a third image sensor for capturing an image of light entering from the third prism, and a video signal processing part for generating a video signal of the observation site based on an imaging output signal captured by each of the first image sensor, second image sensor and third image sensor. The first image sensor includes a color filter.SELECTED DRAWING: Figure 3C
