Abstract:
An attached matter detector includes a light source; an imager receiving transmitted light from a predetermined imaging region on a light-receiving region for an imaging region and imaging an image of the imaging region, and receiving reflected light on a light-receiving region for attached matter detection when light from the light source is reflected by attached matter and imaging an image of the attached matter; a parameter calculator of an image for an attached matter image region calculating a parameter of an image for an attached matter image region as information of an image region of the attached matter; a parameter calculator of an image for an imaging region calculating a parameter of an image for an imaging region as information of the imaging region; and an output device of an attached matter state signal outputting a signal showing a state of the attached matter based on the calculated parameters.
