Abstract

A scanning endoscope apparatus includes a light source section that emits illumination light, an optical fiber that irradiates the illumination light from a distal end to a subject with directivity, a drive element and a scanning drive section that perform scanning by the distal end of the optical fiber, a first light detection section that detects light from a direction of the distal end of the optical fiber, a second light detection section that detects light from an entire scanning range, and an image processing section that forms image information to be outputted to a display section based on a result of addition of a detection result corresponding to an external factor light component in a first light detection result and a second light detection result.

Claims5

Dependent claims

A scanning endoscope apparatus comprising:

a light source section that emits illumination light;
a light conducting section that conducts the illumination light and irradiates the illumination light from a distal end to a subject with directivity;
a scanning section that performs scanning by changing a direction of the distal end of the light conducting section;
a first light detection section that detects light from the subject in the direction of the distal end of the light conducting section;
a second light detection section that detects light from a scanning range of the distal end of the light conducting section by the scanning section with directivity which is broader than directivity of the first light detection section;
an image processing section that performs addition processing on a detection result corresponding to an external factor light component in a detection result by the first light detection section and a detection result by the second light detection section, and forms image information to be outputted to a display section, which displays an image, based on a result of the addition processing.
