Abstract

PURPOSE:To attain accurately diagram input to a desired position even with plural input devices, by bringing the mode to the normal display mode displaying input points including an input start point when the input operation is performed with a prescribed condition. CONSTITUTION:The input operation is started from a writing input plane 103 of a diagram input device 100 and coordinate information reaches an operation circuit 105 via a signal line 107. The circuit 105 writes the input start point in a picture memory 106 and monitors whether or not the input point is obtained continuously. Further, the manual input is performed at a time t0 at first and no movement of manual points is attained. The same coordinate information is transmitted continuously from the device 100 to the circuit 105. Since the input points are obtained continuously, the circuit 105 performs the input position display mode for a time T1 from the time t0 and the normal display mode. In other cases, the normal display mode is not performed.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a system for displaying hand-drawn J-shapes (including sentence size and cursive writing), in which at least the input start point of the input figure is detected at the start of input. Hands-on 1 to be displayed
This relates to a method of displaying type 1 information.

[Technical background of the invention]

The handwritten figure display system, as shown in Fig. 1,
A graphic input device l that extracts coordinate value information of a graphic including handwritten characters and symbols, and this graphic human power V': 1. I
It consists of a processing device 2 which inputs and processes the coordinate value information of a figure sent from the processing device 2, and a figure output device 3 which displays an image of the figure based on the output of the processing device 2.

In such a system, the input portion of the graphic input device 1 may be, for example, a writing input surface configured such that when pressure is applied, the coordinate values of the point to which the pressure is applied are input. , is a writing input surface configured to input coordinate values using an electromagnetic induction method.

On the other hand, as a whistle marking instrument, a ballpoint pen or a pencil is used for the above-mentioned pressure type, and a ballpoint pen with a magnetic field detection coil is used for an electromagnetic induction type.

Therefore, for example, if paper 5 such as No. 21 IA is placed on the above-mentioned input surface [1~, and r reach. In processing sequence 2, appropriate processing is performed, and the processing concludes! +1: is sent to the (C1 type output device, 3.) As a result, for example, the CRT screen (
The characters iXJ will be displayed on i as shown in Figure 2 B. Here, the characters [Yj] are displayed on the right side of the character (-X) on the graphic output device 3's c i<, 't' screen 0. If you wish to do so, write the operation name ``Yj on the writing input surface of the graphic input device l'' on paper 5 with a ballpoint pen, as shown in Figure 3A.Then, as shown in Figure 3B, the graphic output equipped w3 CR7
The characters 1' Y J are displayed on the screen 6.

In this way, handwritten figures can be displayed on a single figure input device.
In the system that is performed based on the input from 1, the figure that you want to input is 7 taps [[
All you have to do is fill in the desired digit in 1ti. Tsumashi, the operator is
Since you can always check the input position by looking at the figure written on the paper on the writing input surface, human errors do not occur.

[Problems with the background art] However, as shown in FIG.
The shape puppet power bowl 1 and the figure input device 1' are connected,
In a system in which the display is transmitted 1''J to one graphic output device (3), the following problem occurs.

That is, the fifth paper 7 is placed on the writing input surface of the graphic input device 1.
As shown in Figure A, it is assumed that < rXYJ is entered with a ballpoint pen. Next, from the graphic input device 1', as shown in FIG. 5B, the characters "
Enter ``Z'' (7) and connect the graphic output device @ 3 as shown in Figure 5C.
Suppose that there is a request to display rXY ZJ on C'J CRT picture 1ti 9 J:. In this case,
For those who input from the graphic input device 1', the 51st RI
As shown in B, because the position of rXYl is unclear, rYJ and rZJ may overlap. Furthermore, when inputting a figure more complex than the characters described in 2 below, there is a high possibility that the input will be repeated.

Furthermore, figure human power i1? If an attempt is made to input a figure from the figure input device f+\,1' in an appropriate position on the figure input from 'il', the above-mentioned situation becomes increasingly difficult.

In this situation, as shown in FIG. 6, the graphic input device 1,
A handwritten graphic display system consisting of a processing device 2, a graphic output device 3, a graphic input device 1', a processing device, 2', and a graphic output device 'i! This problem also occurs when the handwritten graphic display systems from V and 3' are separated and connected via the transmission line 11. In other words, in this case, the graphic input device,
The image of the figure input from J is displayed on the figure output device 3 and the figure output device 63', and the figure input device 1
Since the graphic image inputted from ' is similarly displayed on the graphic output device 3' and the graphic output device 3, the problem described in FIG. 5 similarly occurs in this system as well.

Therefore, as shown in FIG. 7, the graphic input device f'il: I
and the graphic input device 1' are provided with switches 1a+1'a for instructing the input position display mode, respectively. and,
When switch la (or l'a) is turned on, 1. An input position display mode instruction signal is output to the processing device 2. After the processing bag Pt2 receives this instruction signal, the coordinate value information of the figure sent out from the figure input device 1') is displayed to indicate the input position. In other words, in the input position display mode, if the operator manually applies a ballpoint pen to the approximate position of the paper on the writing input surface of the input device 1 (or l/), the It is imported into the processing device 2, and an image of that position is displayed on the graphic output device fi3. Therefore, the operator 1 looks at the input position display of the graphic output device 3, makes a full judgment as to whether that position is the desired position □, and continues until the desired position is reached. ) Continue typing on the paper with a ballpoint pen. When the desired position is found, the operator turns off switch l'a. Then, the processing device 2 returns to the normal intimidation mode. Therefore, the operator continues to input graphic information from the desired position described above.

However, according to this method, the operator has to turn on and off the switch la (or t or 1'a) and input figures, which has the disadvantage that the work is cumbersome and difficult to perform. Ta. Furthermore, if the switch la (or 1'a) is operated incorrectly, an input error will result.

[Purpose of emitting ψ]

The present invention has been made in view of the above-mentioned deficiencies and a. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for displaying handwritten graphic information that allows a user to manually draw an accurate graphic at a desired position even in a system where a plurality of graphic input devices are present.

[Overview of the invention]

Therefore, in the present invention, when an input operation is started, based on the 11y value information fH sent from the graphic input device,
Shao Qinduo performs the human power position ↑fi1 display mode operation to display the input start point, and then if the human power action is not performed under the 1'91 constant condition, the input position f, the figure displayed in the '7f litigation mode is Instead of continuing to display, when an input operation is performed under predetermined conditions, a normal display mode operation is performed in which input points including the input start point are displayed.

[Embodiments of the invention]

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 8 is a block diagram showing the paralyzed graphic display system in more detail. In the figure, 1.00 represents a graphic input @fft, 101 represents a processing device, and 102 represents a graphic output device. The graphic input device ji, 100 has
There is a writing input surface 103. The processing device 101 includes an arithmetic circuit 105 and an image memo! JH)6 is included.

Then, the system is turned on and the graphic input device displays 100
Figure information (coordinate values) input from the input field 103 of
is extracted and sent to the operator circuit 105 of the processing device 101 via the signal line 107. The arithmetic circuit 105 has a processor function, and performs a calculation to interpolate between the input coordinate values and the input coordinate values.
The input coordinate values and the complementary result coordinate values are stored in image memory 1.
Store in 06.

Then, the graphic output device 102 inputs, outputs, and CR data in the image memo +7106 via the signal line 108.
Display on T@ surface 109. 0 Furthermore, in this embodiment, when an input operation is started,
The rendering flt circuit 1.05 accesses the image memory 10G and performs the input position 1; (mode) in which at least the input start point is displayed. In this embodiment, the display is performed only for the input start point. shall be.

First, an input operation is started from the compost input surface 103 of the graphic input device M: 100, and coordinate value information reaches the arithmetic circuit 105 via the signal line 107. It is assumed that the arithmetic circuit 105 determines whether or not a manual operation has been started based on whether or not coordinate value information is sent. Now, as shown in Figure 9, time t
. In this case, if entry is started with a ballpoint pen at *:ii::input 1 town 1.03, the arithmetic circuit 105 performs the input position display mode.

That is, the input start point is stored in the image memory 106, and then a check is made to see if there is an input operation under predetermined conditions. The predetermined condition here is that the human power points are continuously it), and even if you move from the r11 human power starting point to lt/-
This refers to the case of one input (when the ballpoint pen is in contact with the paper) or the case of continuous graphic input from the input starting point. Therefore, if you write a point with a ballpoint pen and then remove the ballpoint pen from the paper on the writing input surface 103, the process ends in only the input position display mode.

For example, as shown in FIG. 9, at time t. If a handwritten input is executed between t1 and time t1, the input position/minus 1 display mode is performed for T1 time, and then the input operation waits.

In this case, the arithmetic circuit 105 monitors the time during which an input point (even if the coordinates are the same) is obtained, and if the written input is stopped before a certain amount of time elapses, the input point is The data corresponding to the input start point in the one-image memory 10G is cleared so that the start point is not displayed. If you do this,
When the operator wants to perform input as explained in Fig. 5, the operator turns on a rough voltage check, inputs the input start point, completes the input within a predetermined time, and then returns to the desired input position. The input starting point is displayed temporarily until it is found, and then it disappears.

With reference to FIGS. 10 and 11, a case will be described in which a predetermined condition is satisfied and the normal display mode operation is performed.

In FIG. 10, first, time t. The text is entered in
It is assumed that there is no movement of the writing point. The same coordinate value information is continuously sent from the graphic input device 100 to the performance circuit 105. Therefore, since the input points to the arithmetic circuit 105 are consecutively 1:,), the time t is reached. After performing the T1 time input position display mode, the normal display mode is performed. In this case, the data in the image memory 106 that is compared to the input start point is written as a whole, and then cleared 7? stomach.

This allows you to input points.

In FIG. 11, time t. It is assumed that the handwriting is performed at , and the writing point continues to move. From the graphic human power device 100, different coordinate value information is continuously transmitted to the operating trout 1 circuit 10.
5. 1/L, since different coordinate value information is successively displayed, the C control circuit 105 performs the input position display mode for an extremely short period of 1 to 2 hours, and then performs the normal display mode. Then, the continuously obtained coordinate value information is complemented, and all the included coordinate values are stored in the image memory 106. , this allows CRT
On the iii screen 109, the figure as entered by the operator is displayed. This operation is performed, for example, by finding the desired input position as explained in FIG.
This is a case where input is started after that and the desired figure is input.

By the way, figures are not always the result of continuous written input. for example,
For characters, the start of the input operation and the interruption of the input operation are constantly repeated (the ballpoint pen is in contact with the rod H+, the input 'U!', or is stale).

Therefore, the input position display mode operation is changed to 1t during the input operation.
The input operation is performed when the time from No. 11 to the start of the next input operation is longer than a predetermined time. In this way, if the input operation continues within a predetermined period of time, the normal display mode is always set, which is optimal for inputting characters. This will be explained with reference to FIG. Suzu, it's time. Assume that an input is made at , and a series of different input position expansion value information is output from the graphic input device 10 (+).Then, the input position display mode is performed for 12 hours and immediately changes to the normal display mode.Time At t2, the ballpoint pen enters the writing input surface 103
Suppose that the ballpoint pen comes into contact with the second brush stroke surface 103 at time t3, when the ballpoint pen is separated from the pen and T3 time has not yet elapsed. Then, the E9 circuit 105 determines that the period from the interruption of the manual operation to the start of the input operation is not longer than the predetermined time (1 til at T3), and returns to time t. From now on, the normal display will continue.

Assume that at time L4, the manual operation is interrupted for T, A hours or more, and at time t5, the input IJi operation is started. In this case, the operator circuit 105 determines that the time from time t4 to time t5 is longer than the predetermined time (1.3 hours), and turns off the manual position display mode. Historically, after time t5, different coordinate values 1n are successively sent to the arithmetic circuit l.
O! When pressed to 5, the mode becomes normal display mode.

Here, the correspondence U between the writing input surface 103 and the image memo ')H)6 will be briefly explained. Sitting h [''22 direction 1
Assume that the coordinates (x, y) of 03 exist at the maximum (am-a r n-1) depths such that the 131st><j A, and correspondingly, is the 13th
Assume that there are mn addresses such as [g+]), and each address has a bits. Then,
The arithmetic circuit 105 stores a group of a pits in the X-axis direction in correspondence with each address in the image memory 1()6.

For example, coordinates (0,0) to (a-1,0) correspond to image memory address O, and coordinates (a,O) to (2a-1,
0) corresponds to image memory address 1, and so on, groups 0 to m-1 of a bits each in the X-axis direction are made to correspond to image memory addresses 0-m-1. Therefore, the coordinate point whose y coordinate is q and whose X coordinate is the rth coordinate of the p group is stored by the arithmetic circuit 105 in correspondence with the rth bit of the qm-1-p address in the image memory 106.

With such correspondence, the input start point is displayed in the input position display mode described above, and when the normal display mode is not selected, the performance circuit 105 displays the data in the image memory 106 corresponding to the input start point. Just clear the data.

Furthermore, in the following explanation, if the 1-1 shape displayed in the input position display mode is the same as the normal display, it is difficult to tell which figure is currently being input. Therefore, it is conceivable to make the figure blink, for example, or to make it a star mark or an X mark. When lowering the blink, the calculation time 1"i'i 105 corresponds to the display position!
10 (1. Write and clear the data to the address in i. It's fine. It's fine. Star marks and X marks are picture 12. Just write such data into the memory 106.

Furthermore, if a part of the figure is filled in, the image "5j memo" J10 corresponding to ωIP11 that should not be displayed.
Invert the contents of the address in G.

〔Effect of the invention〕

If the system of the present invention described above is used, when the input starts, the input position display mode is first entered, so that it becomes possible to input the figure at the desired position -\.

In particular, if a predetermined condition is not met, the figure displayed in the input position display mode is erased, thereby preventing input errors and ensuring accurate input. Furthermore, if input is interrupted for a predetermined time or more at d2 before entering the input position display mode, characters and symbols can be input smoothly.

In the above method, when the graphic output device is provided separately, the graphic in the input position display mode is displayed only on the graphic output device to which the graphic input device Kt belongs. The aforementioned effects can be obtained.
