Abstract:
A character-recognition system for inputting character data in a digital mobile communication terminal, said character recognition system comprising:a display; a touch panel for generating electronic signals in response to pressures from written characters on a writing surface of said touch panel; a terminal Pen-off for periodically detecting whether or not the input of said character data is made through the touch panel for turning on the character-recognition system of the terminal; a touch panel driver for converting analog coordinate data into digital coordinate data, and outputting touch panel state data; a character data base for storing character data comprising shapes and number of strokes; character-recognition means for comparing said digital coordinate data and said number of strokes with corresponding character data stored in said character database, said character recognition means further providing addresses of said corresponding character data; a character code storage for storing character codes corresponding to the character data stored in said character data base; and a controller for: calculating stroke data of said written characters from said coordinate data and said touch panel state data; supplying said calculated stroke data to said character-recognition means; retrieving character codes from said character code storage corresponding to said addresses of said corresponding character data; and displaying said retrieved character codes on said display.
