Abstract

PURPOSE:To set up a character on an optional position of a tablet by specifying a character frame before or after entering a character and displaying character frame information on a display device capable of displaying coordinates corresponding to that of the tablet at the rate of 1 to 1. CONSTITUTION:The hand-written character recognizing device is provided with the table 1 for outputting written coordinate information, a signal conversion part 3 for converting the coordinate information and outputting the converted result as coordinate data, a character frame storing part 4 for outputting character frame data previously stored correspondingly to the coordinate data, a recognizing part 6 for executing the character recognizing processing of the inputted coordinate data based upon the character frame data and outputting the recognized result, a display processing part 5 for executing display processing based upon the character frame data and the recognized result, and the display device 2 for displaying the character frame data and the recognized result so as to correspond to the coordinates of the tablet 1 at the rate of 1 to 1. The coordinate data specified at the time of inputting a character are transmitted to a character frame storing circuit to change the position of the character frame and the changed character frame data are displayed on the display device 2 corresponding to the coordinates of the tablet by the display processing part 5. Thus, the character can be inputted in accordance with the displayed character frame.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a handwritten character recognition device that recognizes handwritten characters written on a tablet.

[Conventional technology]

FIG. 2 is a block diagram of an example of a conventional handwritten character recognition device.

In FIG. 2, 11 is a display for displaying the recognition results on the tablet 1, 13 is a signal converter for inputting coordinate data on the tablet, and 14 is character frame data for storing preset character frame data. 15 is a display processor for displaying recognition results; 16 is a recognition processor; a character frame area in which each character is written is predetermined at a fixed position on the doublet 11; Each character was separated and identified by determining its coordinates and character frame coordinates. For this reason, I took the approach of not printing a character frame on the writing surface of the preliminary tablet 11.

[Problem to be solved by the invention]

In the above-mentioned conventional handwritten character recognition device, the character frame for writing is fixed, so if the position of the character to be written is changed, it is necessary to take measures such as changing the system settings. When inputting both text and graphic information, there are drawbacks such as the character frame getting in the way when inputting graphics.

[Means to solve the problem]

The handwritten character 32 recognition device of the present invention includes a tablet I for outputting coordinate information of a handwritten character, a display device for displaying coordinate information in one-to-one correspondence with the coordinates to the tablet, and at least one There are two levels: 1F for specifying a character frame for each character, and 1F for displaying the coordinate information written on the display and the specified character frame.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows 71 of a handwritten character recognition device according to an embodiment of the present invention.
Fig. 172.

This embodiment uses a tablet 1 that outputs written coordinate information.
1, a signal conversion section 3 that converts the coordinate information from the tablet 1 and inputs it as coordinate data, and a character frame storage section 4 that outputs pre-stored character frame data corresponding to the input coordinate data. 52. Perform character recognition processing on the input coordinate data based on the character frame data and output the recognition results.52. a recognition unit 6, a display processing unit 5 that performs display processing based on character frame data and recognition results, and a display processing unit 5 that performs display processing based on character frame data and recognition results;
A display band 2 for displaying character frame data and recognition results corresponding to pair 1 is provided.

In this manner, in this embodiment, when inputting characters, the scribe specifies the character frame position by touching the second upper corner of the first character [1] with a pen. The specified coordinate data is transmitted to the character frame storage section C9 and character 4.4. b position is changed. The changed character frame data is displayed by the display processing section 5 on the display 2 corresponding to the coordinates of Taffle I.

The scribe can input text by typing in the displayed text box.

〔Effect of the invention〕

As explained above, according to the present invention, the character frame is specified before or after character entry, and the coordinates of 1~ and 1+
By displaying the character frame information on the display that can be displayed at the coordinates in the column 11, it can be set at any position on the tough 1 knot, and can be set at any position on the tough 1 knot. When inputting I-type data, it has the effect of being able to write without leaving the character frame blank.
