Abstract: Provided is a correction data generation method that includes acquiring captured image data by imaging an indicator that is related to a predetermined illness; plotting a real imaging data point that corresponds to the acquired captured image data in a predetermined color space that is associated with the predetermined illness in accordance with a color component of the data point; calculating a correction value for correcting the values of pixels that make up a captured image captured by an electronic endoscope based on the distance between the data point and a predetermined target point in the predetermined color space; and storing the calculated correction value.

Abstract: 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”.

Abstract: 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.
