According to the present disclosure, for example, when a line of a character as an object is to be thickened, an enlargement process is performed. Then, a correction process is performed to deform the line of the character into a moderate thickness. Moreover, when a line of a character as an object is to be thinned, a reduction process is performed. Then, a correction process is performed to deform the line of the character into a moderate thickness. Also for a hollow character as an object, a similar contour process is performed to deform the line of the hollow character into a moderate thickness.
