摘要： An endoscope system has an optical fiber that is configured to transmit illumination light emitted from a light source to the tip portion of a scope; a scanner that is configured to spirally scan a target area with the illumination light by vibrating the tip portion of said optical fiber; and a pixel signal detector that is configured to detect pixel signals on the basis of light reflected from the target area at a given sampling rate. The endoscope system further has an image-pixel generator that generates image pixels of an observation image on the basis of the pixel signals sampled or detected in accordance to the sampling rate. The image-pixel generator generates each image pixel from a “proximity pixel group”.

摘要： An endoscope system has an optical fiber configured to transmit illumination light emitted from a light source to the tip portion of a scope; a scanner configured to spirally scan a target area with the illumination light by vibrating the tip portion of the optical fiber; and an image generator configured to generate an observation image from image-pixel signals that are obtained from light reflected off of the target area. The endoscope system further has a resolution adjuster that adjusts a resolution of the observation image in accordance to a photographic state by controlling at least one of either a movement (drive) of the fiber tip portion or a sampling of the image-pixel signals.
