Abstract
An image processing apparatus includes a storage unit, a conveyance unit configured to convey a document, a reading unit configured to read an image of the document line by line in a main scanning direction, a check unit configured to check a free space of the storage unit, a detection unit configured to generate detection processing data for determining a position of a portion of the image in the main scanning direction of the reading unit where the image cannot be read correctly and to detect the position using the detection processing data, both in response to the free space of the storage unit being sufficient to store the detection processing data, and a correction unit configured to correct a pixel value of the portion corresponding to the position detected by the detection unit in the image read by the reading unit.
