1. An image processing apparatus comprising: rotation circuitry configured to rotate an original image including a hand-drawn element; exaggeration circuitry configured to perform, on the hand-drawn element of the original image having an angle of rotation, an exaggeration process that thickens a line width of a drawn line in the hand-drawn element to generate an exaggerated image, with a degree of thickening corresponding to the angle of rotation; and reduction circuitry configured to reduce the exaggerated image to generate a reduced image of a predetermined size smaller than a size of the original image.
