Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device in which a transparent input section and a display section for displaying input data are stacked and arranged.

[0002]

2. Description of the Related Art Conventionally, an input / output integrated handwriting electronic device has a laminated structure of a display section and an input section and is operated by an input means such as a pen. With such a configuration, when setting the state using software-like switches on the display screen and editing the data such as already entered characters and figures, the same operation as writing on paper Sex is obtained.

A GUI (Graphical User Interface) is used as a machine for inputting and editing characters and figures.
There are many personal computers that have functions and a mouse that uses the mouse instead of the pen to realize the same function.

4 to 6 are views showing an example of a graphic editing processing screen in this kind of electronic equipment.

FIG. 4 shows a mode 4 in which the drawing designation area 40 is a circle.
1 corresponds to the screen displayed when a circle is drawn with the radius mode 50 specified. For this circle, FIG. 5 is an example of a screen when the straight line mode 45 is selected and a line segment is drawn on this circle. However, in this case, a personal computer +
With a mouse, draw a straight line with the mouse while pressing a specific key (eg, shift key). By doing so, a line can be drawn toward the center of the circle that cannot be glanced at with respect to the circle shown in FIG. Then, a pie chart desired by the user can be created as shown in FIG.

[0006]

However, in the above-mentioned conventional example, when a presentation material or the like is created (that is, when characters and figures are mixedly present on one screen), a pie chart or the like is created on the created material. At the time of description, the arc and the straight line are combined to make them. The operation method will be described step by step. First, the circle mode 41
Is selected (a circle mode 41 shown in FIG. 4 is selected), and a radius or diameter mode is secondly selected to draw a circle (a radius mode 50 shown in FIG. 4 is selected).
Then, thirdly, the straight line mode is selected, and fourthly, a straight line is drawn while pressing a specific key and / or an appropriate silent line is drawn, or a line segment is drawn by using a measure attached to the upper / left side. .

As described above, when a straight line is drawn from an arc toward its center, the center is not clearly indicated. Therefore, in the case of a combination of a personal computer and a mouse, a straight line must be drawn while pressing a certain specific key. In the input / output integrated pen operation, it is necessary to draw a straight line while visually observing properly or by using the upper / left measure. Not only does it give a natural feel, but there is also the problem that it is not possible to draw even more beautiful pie charts.

The present invention has been made to solve the above problems, and when drawing a figure by a touch operation, the center position of the figure already drawn is derived and clearly indicated. It is an object of the present invention to provide an electronic device which can give an index to a new graphic editing that extends inside and outside the contour line of the existing graphic and support the operator's graphic drawing instruction operation.

[0009]

An electronic device according to the present invention comprises a display means for displaying an input character or a figure, and an input means having a transparent touch input section laminated on the display means. , Determining means for determining the depression of the figure edit request area set in the touch input section, and when the determining means determines that the figure edit request area is depressed,
It has a derivation means for deriving the center coordinates of the closed figure displayed on the display means, and a clarification means for clearly indicating the center position on the display means based on the center coordinates derived by the deriving means.

[0010]

In the present invention, the derivation means is displayed on the display means when the determination means for determining the depression of the figure edit request area set in the touch input section determines that the figure edit request area is depressed. The center coordinates of the closed figure that is present are derived, and the clarification means clearly indicates the center position on the display means based on the derived center coordinates, and for a new figure editing that extends inside and outside the contour line of the figure being edited. An index is given to support the operator's graphic drawing instruction operation.

【Example】

[First Embodiment] FIG. 1 is a plan view illustrating the configuration of an electronic device according to a first embodiment of the present invention, and particularly corresponds to a case of an input / output integrated electronic device.

In the figure, 1 is a transparent tablet consisting of a digitizer of a transparent resistance film type for inputting characters and figures, 2 is a display device for displaying the data inputted from 1 and 3 is an input state ( This is a mode selection key for switching the edit mode etc.
Can be selected from on the tablet.
Reference numeral 4 represents the boundary of an area in which direct input is possible by pen operation. Reference numeral 5 is a mark that clearly indicates the center where the figure is present when a closed figure such as an arc in the present invention is drawn.

The process until the center 5 of the figure shown in FIG. 1 is specified will be described below with reference to FIGS. 2 and 3.

FIG. 2 is a block diagram illustrating a control configuration of the input / output integrated electronic device shown in FIG.

Here, the LCD display unit 18 (see FIG.
Display device 2 etc.), transparent tablet unit 19
(Including transparent input tablet 1 etc. in FIG. 1), LC
The D unit 18 and the transparent tablet 19 are the gate array 1
5 (GA) via the data bus 20 of the CPU 14 and the data bus 21 of the RAM 16 and the ROM 17 side.

Gate array 15 and LCD unit 1
8. Data bus 2 for LCD between transparent tablet 19
2. Connected by the tablet data line 23.

In the electronic device configured as described above, the determination means (CPU) for determining the depression of the figure edit request area set in the touch input section (transparent tablet unit 19)
When 14) determines that the figure edit request area is pressed, the derivation means (CPU 14) derives the center coordinates of the closed figure displayed on the display device 2, and based on the derived center coordinates. The indicating means (CPU 14) indicates the center position by the mark 5 on the display device (LCD unit 18).
In order to support the operator's graphic drawing instruction operation, an index for new graphic editing that extends inside and outside the outline of the graphic being edited is given.

In the above structure, the voltage corresponding to the depression of the pen is input from the transparent tablet 19 to the gate array 15 through the tablet data line 23. This voltage is A / D converted in the gate array and the digital value is input to the CPU 14 via the data bus 22. The CPU 14 performs the above control, detects the X and Y coordinates on the transparent tablet from the values input together with it, and lights the dot on the LCD panel 2 corresponding to the detected X and Y coordinates.

A control program is stored in the ROM 17, and it is possible to judge whether the command input section shown in the mode selection key 3 in FIG. 1 is pressed or the data input section is operated. When the data input section is operated, the RAM 16 stores the coordinate values and the like input from the transparent tablet.

A mode selection key (command input section)
When 3 etc. is operated, the judgment of the difference from the current state is R
The program stored in the OM 17 executes and stores each state in the RAM 16.

The graphic editing processing operation in the electronic apparatus according to the present invention will be described below with reference to the flow chart shown in FIG.

FIG. 3 is a flowchart showing an example of a graphic editing processing procedure in the electronic device according to the present invention. Note that (1) to (12) indicate each step.

In step (1), for example, the main body is powered on and waits for a key of the electronic device integrated with input / output (in this embodiment, a determination state as to whether or not the transparent tablet is pressed).
Is. If the transparent tablet is pressed (hereinafter,
If it is not a pen down), go to the HALT state of step (12) to suppress power consumption, go to the key waiting state of step (1) again, and loop here until there is a pen down. If you pen down on a transparent tablet, go to step (2) for now.

In step (2), it is judged whether or not the pen-down position is in the command key area. If it is the command key, go to step (3). If it is not the command key, go to step (6) to enter the enterable area. Or not. In step (6), if the pen is down to a region other than the input area, no processing is performed on the point that was taken, and in step (7) the process is canceled and the key wait state is returned.

Next, if it was a pen down to the input possible area in the previous step (6), it goes to step (8) and the taken point is stored in the RAM 16 and, at the same time, it is pen down in step (9). The dot under the display is lit up. Then, the key waiting state is resumed.

On the other hand, if it is determined in step (2) that the command key area has been operated, the process proceeds to step (3).

In step (3), as a first step of judging which key in the command key area is pressed, it is first judged whether or not the edit key is operated. If it is not the edit key, the next command is executed. Go to step (10) to check the key. In this step, it is determined whether or not the key is a key for changing the thickness of the pen. If it is not this key, the process proceeds to the determination (not shown) of other command keys.

If the thickness of the pen is to be changed, the process goes to step (11) to change the thickness of the pen being drawn and / or the thickness of the pen such as the selected figure. There are command keys other than the above, but these are also processed according to the function of the key, and the key waiting state of step (1) is also entered.

Next, if the key processed in step (3) described above is an edit key, it is judged in step (4) whether or not there is a closed figure, and if it does not exist. If there is a key waiting state, go to step (5).

In step (5), the center mark 5 is displayed in order to clearly indicate to the user the center point of the (closed) figure of the present invention.

In this embodiment, as shown in FIG. 1, the mark is displayed so as to surround the central point. By doing so, it is effective when, for example, adding to the previously described figure or the like (especially effective when creating a pie chart). [Second Embodiment] In the first embodiment described above, a method is used in which a mark surrounding the center point is turned on as a mark for clearly indicating the center of a closed figure or the like. Since it is the main purpose, it is possible to blink this mark, and this processing can be easily dealt with by only modifying a part of the control program. [Third Embodiment] In the first embodiment, the processing is performed on the same screen. However, since all closed figures are targeted in this case, a certain designated data It is also easy to apply the process of the present invention only to a figure selected to be processed by
There is a possibility that this will be more advantageous in consideration of processing speed and the like. [Fourth Embodiment] In the first embodiment, the processing of the present invention is performed on the same screen. However, considering the recent decrease in semiconductor price, etc. Import the target figure such as the selected figure (of course,
It is also possible to add a line segment such as a straight line aiming at the cholera mark by clearly indicating the center mark which is the gist of the present invention on the figure on the window) Needless to say. [Fifth Embodiment] In the embodiments shown in FIGS. 1 to 3, a case has been described in which a command key area is provided outside the inputtable area, and the gist of the present invention is executed during this editing. In particular, the command key area is not provided, and the fixing method to the edited state is defined as a rectangular area in which a series of actions from pen-down to pen-up on the input-enabled area is performed. It goes without saying that the present invention is effective for all the embodiments and the variety is widened.

According to the above-described embodiment, in particular, in the input / output integrated type electronic device in which the input means and the display means are arranged in layers, which can maximize the merit of the pen operation, the data input from the transparent input section can be stored. By providing a specific mode that can be edited and newly added, since the center of the arc is clearly indicated when drawing the pie chart etc. described above with a combination of arc and straight line, it will be added later. It is possible not only to draw a straight line accurately and quickly, but also to draw concentric circles and / or to draw circles that partially overlap each other on the same line, which makes it easier to see the display and improve the operability of the device. be able to.

The present invention may be applied to a system composed of a plurality of devices or an apparatus composed of a single device. Further, it goes without saying that the present invention can be applied to the case where it is achieved by supplying a program to a system or an apparatus.

[0034]

As described above, according to the present invention,
When the determination means for determining the depression of the figure edit request area set in the touch input unit determines that the figure edit request area is depressed, the derivation means determines the center coordinates of the closed figure displayed on the display means. The derivation and the descriptive means clearly delineates the center position on the display means based on the deduced center coordinates, so that it is possible not only to draw a straight line to be added later accurately and quickly but also to draw a concentric circle, and Alternatively, even when a circle in which a part of them overlaps each other is drawn on the same line, the visual confirmation of the display is facilitated and the operation feeling of the device can be improved.

Therefore, there is an effect that it is possible to give an index for a new graphic editing that extends inside and outside the outline of the graphic being edited to support the graphic drawing instruction operation of the operator.
