ABSTRACT:
A system for reading characters on an object is provided. The system first obtains color data relating to each color component from the object in which characters expressed in a first color and information expressed in at least a second and a third color which differ from the first color are mixed. Then the color data relating to each color component of the background color of the object and the information expressed in the second and the third color other than the characters are converted in such a way that the influence on the color data relating to each color component of the characters expressed by the first color becomes minimal. After that, only the color data related to each color component of the characters expressed in the first color is extracted by converting the color relating to the each color component.
