Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handwriting input device, and more particularly, it recognizes handwritten characters as image data, performs an enlarging / reducing process, and then processes the image data at a specific position of a display device. The present invention relates to a handwritten input character processing device for displaying.

[0002]

2. Description of the Related Art FIG. 7 shows a flow chart of a conventional process flow of a handwritten character input device of this type. Referring to FIG. 7, the character (string) written by the user in step 71 is stored in the main storage device as image data (the input data is point (coordinate) data) in step 72, and then in step 73. Then, the coordinate data is converted into display data, and an image input to the display device is displayed.

Next, in step 74, it is checked whether handwritten characters have not been input to the tablet for a certain period of time. If no input is made for a certain time, step 75
At, delete the character (string) from the screen (however, the image data is stored internally).

On the other hand, if the input is made within the fixed time, the process returns to step 71.

Following the processing of step 75, step 76
In the above, the coordinate data of the handwritten input character stored in the main storage device is used to generate the coordinate data such that an image obtained by enlarging or reducing the handwritten input character is obtained.

Next, in step 77, the coordinate data generated by the enlarging / reducing process is stored in the main storage device, and display data is created based on the coordinate data generated by the enlarging / reducing process in step 78. Display on the display device.

The conventional handwritten character input method has the following two methods.
There are two methods.

The first method, as shown in FIG. 8, enables input to any portion (area) on the screen. The advantage of this method is that it retains the feeling of writing characters on ordinary paper.

The second method is to display an input frame on the screen and write characters in the input frame, as shown in FIG. The advantage of this method is that the handwritten character is reduced based on the size of the input frame to be displayed in the size desired by the user. That is, as shown in FIG. 9B, the character “I” displayed as a handwritten character has the same size as the characters “A” and “U” on both sides of the character string input (see FIG. 9A). It is displayed in a state in which the relationship of the height (“I” is 50% lower than “A” and “U”) is maintained.

[0010]

The above-mentioned conventional technique has a problem that the enlargement / reduction ratio of handwritten characters cannot be controlled while maintaining the feeling of writing on paper. This problem will be described in detail below.

For example, as shown in FIG. 10, "I am
When a handwritten character string "a boy" is input using the first input method, "am", "a", "bo"
The size of each word "y" after scaling is displayed in the same height when compared with the head "I" in height. The reason for this is the parameter for scaling the input character string. That is, the criterion for determining the enlargement / reduction is that the parameter of the enlargement / reduction ratio is determined only by the element that makes the size of the input character string a constant height.

If the handwritten character is input by the second conventional method, the size of the character string can be controlled,
Since it is a method of writing characters in the set input frame, the feeling of writing on paper is lost.

Therefore, the present invention has been made in view of the above circumstances, and an object thereof is to provide a handwriting input device for controlling the enlargement / reduction ratio of input handwritten characters while leaving the feeling of writing on paper. To provide.

That is, as will be apparent from the following description, the object of the present invention is to display a character as shown in FIG. 10 in the above conventional input method regardless of the method of writing characters in the input frame. As shown in FIG. 11,
It is to provide a handwriting input device capable of displaying. Another object of the present invention is to provide a handwriting input device which notifies a user that the enlargement / reduction ratio has been changed.
