Attached matter detector and vehicle equipment control apparatus

An attached matter detector, comprising:

• 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,
• a part of an imaging area of the imaging device is used as an attached matter imaging area which images the attached matter attached to the surface of the plate-like transparent member,
• the light-out image, the light-up image, and the light-out image are continuously imaged in order,
• a light-out image comparison device configured to compare the light-out image just before the light-up image and the light-out image just after the light-up image, and
• a stop device is configured to stop detection of the attached matter if a change in the light-out image just after the light-up image relative to the light-out image just before the light-up image exceeds a threshold by the light-out image comparison device.
