LIGHT SOURCE APPARATUS, ENDOSCOPE SYSTEM AND OPERATING METHOD

摘要

A light source apparatus for endoscopic imaging includes a light source for emitting at least narrow band blue light and narrow band green light, to illuminate an object in a body cavity. The light source is changeable over between field sequential lighting and simultaneous lighting. The light source, upon setting of the field sequential lighting, emits the narrow band blue light and narrow band green light in a discrete manner, and upon setting of the simultaneous lighting, simultaneously emits the narrow band blue light and narrow band green light. A connector is connectable with an endoscope having a complementary color image sensor of yellow, magenta and cyan, for imaging the object. A controller sets the field sequential lighting assuming that the endoscope is connected to the light source and assuming that the light source is used for emitting the narrow band blue light and narrow band green light.

主权项

1. A light source apparatus for endoscopic imaging, comprising:
a light source for emitting at least first narrow band light and second narrow band light having a longer wavelength than said first narrow band light to illuminate an object in a body cavity, said light source being changeable over between field sequential lighting and simultaneous lighting, wherein said light source, upon setting of said field sequential lighting, emits said first narrow band light and said second narrow band light in a discrete manner, and upon setting of said simultaneous lighting, simultaneously emits said first narrow band light and said second narrow band light; a connector connectable with a first endoscope having a complementary color image sensor for imaging said object; a controller for setting said field sequential lighting assuming that said first endoscope is connected to said light source and assuming that said light source is used for emitting said first narrow band light and said second narrow band light.
