Embodiment Construction

[0063] FIG. 1 is a block diagram showing an electrical configuration of a handwritten character input display device 1 as an embodiment of the present invention. The handwritten character input display device 1 is composed of a display unit 2 , an input unit 3 , a CPU (Central Processing Unit) 4 , a ROM (Read Only Memory) 5 and a RAM (Random Access Memory) 6 . The display unit 2 is realized by, for example, an LCD, and the input unit 3 is provided on a display surface thereof, such as input surfaces of tablet tablets arranged in layers. The aforementioned input surface has a transparent property, and various inputs are performed by pointing on the input surface with the input pen 7 as pointing means.

[0064] The CPU 4 controls the operation of the entire handwritten character input display device 1 according to the programs stored in the ROM 5 . Specifically, in the ROM 5, a program for displaying handwritten characters input from the input surface with the input pen on the ...

Abstract

When a character is handwritten and inputted from a 1st display screen by the use of an input pen, an input part 3 outputs input character information including input position information expressing an instructed coordinate point. The inputted handwritten character is displayed on the 1st display screen. A character recognition part 33 arrays plural previously determined candidate character information to be recognized in the descending order of similarity to the inputted character information to prepare a candidate character string. When a 1st candidate character is not a required character and another character is selected, a correct character display information part 37 displays the detailed information of the selected candidate character on the 1st display screen under a condition such as superposition with the handwritten input character which is previously set up in a function setting / selecting part.

Description

technical field [0001] The present invention relates to a handwritten character input display device equipped with a tablet or the like with an input surface arranged on the display surface of a display device utilizing a CRT (cathode ray tube) or a display device such as an LCD (liquid crystal display device) The input device, for example, can be realized by electronic equipment such as a personal computer or a word processor, and uses the aforementioned input device and display device to input and display handwritten characters and perform character recognition on the input handwritten characters. Background technique [0002] The handwritten character display device of the prior art is equipped with a display device and an input device with a transparent input surface configured on the display surface of the display device. While being displayed on the display surface, it is also processed as a recognized character for character recognition, and the recognition result is ...
