Title: OPTICAL-SCANNING-TYPE IMAGE-FORMING DEVICE AND OPTICAL-SCANNING-TYPE ENDOSCOPE SYSTEM
Abstract:
Provided is an optical-scanning-type image-forming device that comprises: a light source unit (5) that outputs illumination light; a driving-waveform generating unit (7) that generates a driving waveform; an optical scanning unit (6) that scans the illumination light in accordance with the driving waveform; a light detecting unit (9) that acquires gradation values based on observation light from a subject; a phase setting unit (8) that sets the phase of the driving waveform so as to apply a phase difference to the driving waveform between a prescribed number of frames in one set of frame periods composed of a prescribed number of frame periods; and an image processing unit (10) that acquires one set of images composed of a prescribed number of images in one set of frame periods. The image processing unit (10) interpolates a gradation value of a defective pixel included in an image, using a gradation value in images constituting a set that was obtained prior to the set including that image.
