Rain/moisture and object imaging system for vehicle

An image processing system comprising:

• an imaging device which captures light;
• a light source in the form of an array of plural light emitters, the light source being located at a place where the imaging device can directly capture light reflected by fog on a glass;
• a light source controller which turns on the plural light emitters;
• a lens which is provided in front of the imaging device, a focus of the lens being adjusted to a point beyond the glass;
• and
• an image processor which processes an image captured by the imaging device;
• wherein the image processor processes the image and measures at least one of an extent of fog on an inner surface of the glass, a direction of fog spread, and speed of fog spread on the inner surface of the glass based on a decrease of an amount of the reflected light captured by the imaging device.
