Description

Description: TECHNICAL FIELD The present invention relates to a character box display method, and more particularly to a character box display method suitable for input processing of handwritten characters and graphics from a coordinate input device.

[Prior Art] Generally, in this type of information input device, input characters and graphics are displayed at corresponding positions on a display device. In the case of recognizing this input, a frame is usually provided, and characters and figures in the frame are recognized, and when the position of the character / graphic deviates from the recognition frame, it cannot be recognized. For this reason, conventionally, a character frame paper is placed on the input section, and the input person is restricted to input a character or a figure in the character frame.

[Purpose] The present invention has been made in view of the above-mentioned drawbacks of the prior art, and its object is to display a character frame for a character graphic at a necessary position when necessary, thereby enabling the character frame to be displayed. Eliminates the complexity of the screen caused by constantly displaying
It is to provide a character frame display method that realizes easy-to-see screen display.

Embodiments Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing the information input device of the embodiment of the present invention. In the figure, 1 is a tablet for outputting the XY coordinate information on the line 100, 2 is an operation pen for drawing a character or the like on the tablet 1, and 3 is for displaying the corresponding recognition frame by using the tablet output [x, y]. Switch, 4 is a central processing unit (CPU) for processing the tablet 1 output, 5 is a CRT display section for displaying the pattern information and recognition frame information of the tablet input, and 6 is a display for controlling the display of the CRT display section 5. It is a control unit.

Various function blocks executed by executing a program are shown in the CPU 4. 7 is a pattern memory for storing the input pattern information from the tablet 1, 8 is a frame information memory for storing the frame information such as the position of each frame, the frame size, and the frame shape when the surface of the tablet 1 is divided into frames, Reference numeral 9 denotes a frame pattern generator that searches the frame information memory 8 using the coordinate information [x, y] output from the tablet 1 and generates a corresponding frame pattern at a corresponding position.

FIG. 2 is a flow chart showing the operation of the embodiment. In step S1, the coordinate input [x, y] from the tablet 1 is provided. If coordinates are input, it is checked in step S2 whether the pattern is input. When the switch 3 of the operation pen 2 is pressed, the output signal R thereof becomes HIGH level, indicating that the coordinate output [x, y] is pattern information. Therefore, when the pattern is input, the AND function 10 is satisfied and the process proceeds to step S6,
The coordinates [x, y] are dot-developed in the pattern memory 7. For example, the dot at coordinates [x, y] is set to logic 1. Step S
In 5, the dot-expanded input pattern is displayed in real time on the CRT display unit 5.

When the switch 3 is not pressed, the signal R is at LOW level, indicating that the coordinate output [x, y] is not pattern information. In this case, the AND function 11 is satisfied and the process proceeds to step S3 to search the frame information memory 8 for the coordinate [x, y]. In step S4, a frame pattern is formed and held from the relevant frame information (display reference position, frame size, frame shape, etc.) retrieved and read. In step S5, a frame pattern is displayed on the CRT display section 5.

Incidentally, such a switch 3 may be moved by writing pressure to operate. That is, simply by touching the pen tip on the tablet 1, the signal R is at the LOW level and the coordinate output [x, y] is not the pattern information, but the frame display can be confirmed. Next, when the writing pressure is increased as it is, the signal R becomes HIGH level, and the coordinate output [x, y] becomes pattern information so that characters can be input.

Further, the frame once displayed may be continuously displayed until the pen tip leaves the frame area regardless of the change in the output of the switch 3 (even if the pattern is input).

FIG. 3 is a diagram showing one mode of display. The character pattern “character or figure” that has already been input is displayed as shown in the figure.
This display may be a handwritten character of the input pattern as it is or a printed character of the recognition result depending on the application. When the operator tries to input the next character and touches the pen tip on the tabletton 1 without pressing the switch 3 of the operation pen 2, the corresponding frame 12 is displayed and the dot K is temporarily displayed at the position where the pen tip is pressed. It
Also, the previously displayed frame 12 'has disappeared.

Although the tablet and the pen are used as the coordinate detecting means of the character / graphics input in the above-mentioned embodiment, other devices such as a mouse may be used.

Further, in the above-mentioned embodiment, the case where the character frame is displayed by the selection of the input person has been described, but it may be automatically displayed for each input.

Furthermore, in the above-mentioned embodiment, the case of displaying a rectangular frame has been described, but other, for example, in-frame coloring, luminance change,
It may be displayed by a method such as reverse display or blinking.

As described above, according to the present embodiment, the character / figure recognition frame can be displayed on the monitor as needed, so that the position of the pen can be easily aligned, and special frame paper or the like is not required, and characters can be input quickly and reliably. .

In addition, the frame display is displayed in a necessary part only when necessary, so that it does not interfere with the input operation.

[Effects of the Invention] As described above, according to the present invention, when it is detected that a position for specifying a position for displaying a character frame is designated, the character frame is displayed at the specified position. A character frame is displayed at a required position at any time, the screen is not complicated, and an easy-to-see screen display can be performed.
