Abstract

An attached matter detector includes a light source configured to irradiate light toward a plate like transparent member from one surface thereof an imaging device configured to image reflection light by attached matter on a surface of the plate like transparent member a memory configured to previously store flare information obtained by the image device by turning on the light source in a state without having disturbance light and the attached matter on the surface of the plate like transparent member and a difference information obtaining device configured to obtain difference information between a light up image as an image obtained by the imaging device with the turned on light source and a light out image as an image obtained by the imaging device with the turned off light source wherein the attached matter on the surface of the plate like transparent member is detected based on the difference information and the flare information stored in the memory.
