Abstract
An image processing apparatus includes a reflection member configured to reflect scanning light; a scanner unit configured to scan a document to generate image data and scan the reflection member with the scanning light to generate detection-reference image data; and a detecting unit configured to detect image noise in the generated detection-reference image data in a detection range of a desired number of contiguous pixels in a sub-scanning direction so that the image noise extending in the sub-scanning direction of the generated detection-reference image is detected.
