Claim One:
1. An image processing system comprising: a light source that emits light from one surface side of a transparent member to the transparent member; an imaging unit including an imaging element that captures light emitted by the light source and reflected from a foreign matter attached to the other surface of the transparent member and that captures light transmitted through the transparent member from the other surface side; and an image analyzing unit that analyzes captured image data captured by the imaging unit, wherein the captured image data is formed of a first image area frame containing a first image area that is used for detecting a foreign matter and that corresponds to a predetermined area of an effective imaging area, and is formed of a second image area frame containing a second image area that corresponds to the effective imaging area excluding the predetermined area, and the image analyzing unit applies different rules to the imaging unit between for reading pixel data of the first image area frame and for reading the second image area frame.
