An image processing apparatus includes a reception unit receiving image data, a region determination unit to extract a text region from the received image data, a threshold value calculation unit to calculate the background amount of the extracted text region, and an image correction unit to correct a non-text region of the image data according to the calculated background amount. Since the non-text region of the image data is corrected according to the background amount of the text region, an appropriate correction process can be applied on the image data according to difference in the paper sheet quality and image pickup condition.
