1. An image processing apparatus comprising:
an extraction unit configured to extract one or more character area images from an image; a determination unit configured to determine a pair of character area images to be a combination target based on a degree of similarity of an image feature in each character area image extracted by the extraction unit from different images; and a combination unit configured to combine the determined pair of character area images to form a combined character area image, wherein the combination unit is configured to compare a dynamic range of each overlapping area image and combine using the overlapping area image having the larger dynamic range. |
