Character-recognition system for a mobile radio communication terminal and method thereof

摘要

A character-recognition system provided in a digital mobile communication terminal, comprises a display, a touch panel for generating pressure signals in response to the pressures applied by the characters written on its surface, a touch panel drive for generating coordinate data and touch panel state data calculated from the pressure signals, a character data base for storing character data consisting of coordinate data and stroke data of the characters, a character-recognition circuit for generating the addresses of the precise character data retrieved from the character data base by recognizing the data of the written characters, a character code storage for storing the character codes corresponding to the character data stored in the character data base, and a controller for delivering the stroke data of the written characters calculated from the coordinate data and touch panel state data to the character-recognition circuit, wherein the controller retrieves the character codes from the character code storage corresponding to the addresses generated by the character-recognition circuit in response to the coordinate data and stroke data, and display them on the display.
