  • Publication number: 20050157927
    Abstract: An image digitization system is provided for implementing application software allowing a user to enjoy communication with other users using character data itself and for changing the character data, used by the application software, to increase gaming pleasure. In response to an instruction from the user, a portable terminal unit 1 downloads the application software from a data delivery server 4-1. When the application software is executed by an instruction from the user, the portable terminal unit 1 starts a camera to shoot an image and converts the shot image data to a numeric value according to a pre-set algorithm. The portable terminal unit 1 downloads character data, corresponding to the numeric data, from a data delivery server 4-1 and saves the downloaded character data.
