1. An image processing apparatus that generates an image for character recognition from a read image, the image processing apparatus comprising:
at least one memory that stores instructions; and
at least one processor that executes the instructions to perform:
extracting a character information area, which includes character information from the read image;
classifying handwritten character information and printed character information from the extracted character information area;
clipping a partial image of the area of handwritten character information and a partial image of the area of printed character information classified out of the read image; and
generating the image for character recognition by combining the partial image of the area of handwritten character information and the partial image of the area of printed character information being associated with each other,
wherein the combined partial image of the area of handwritten character information and the combined partial image of the area of printed character information are arranged in a row direction on the generated image even if the partial image of the area of handwritten character information and the partial image of the area of printed character information are arranged in a column direction on the read image.
