Description

Detailed Description of the Invention] (Hereinafter in the margin) 3. Detailed Description of the Invention [Field of Industrial Application] The present invention particularly relates to an electronic device capable of outputting information input from a coordinate input device to an output device. .

[Prior Art] Conventionally, tablets (coordinate input devices) and the like have been used as input devices for electronic devices such as computers.
There are some that are displayed on a display device using a liquid crystal or the like.

[Problems to be Solved by the Invention] However, in such conventional electronic devices, due to the mismatch in the size of the coordinates on the input side and the output side, for example, when drawing a figure on the entire area of the surface of the tablet, In some cases, a part of the graphic may protrude from the surface of the CRT display device, or conversely, the entire surface of the CRT display device cannot be used completely by the tablet. Furthermore, if the shape of the effective display screen of the CIIT display device and the shape of the input surface of the tablet are different, the figures input from the tablet may be displayed distorted.

The present invention has been made in view of the above-mentioned problems, and allows the user to freely specify the range of the effective screen of the display screen, and allows the input information of the coordinate input device to be contained within the range of the effective screen. The purpose is to provide an electronic device that can output the following information.

[Means for Solving the Problems] In order to achieve the above problems, the present invention provides coordinate input means for inputting input information including figures as coordinate values, and output means for outputting input information input from the coordinate input means. and a specifying means for specifying the effective output screen range of the output means, and correcting the output coordinate values of the input information input from the coordinate input means according to the effective output screen range specified by the specifying means and outputting the corrected values to the output means. The present invention is characterized by comprising a correction means for.

[Function] In the present invention, in an electronic device having a coordinate input means such as a tablet, the coordinate values are corrected so that the input coordinates + 11 information from the coordinate input means are within the specified effective screen range. Not only can the figure drawn on the coordinate input means be easily enlarged or reduced to fit the screen of the output means, but the coordinate range of the coordinate input means is larger than the screen of the output means, and large figures can be drawn when inputting. Even in cases where this is not possible, you can specify the effective range of the output screen to prevent it from extending beyond the output screen even if you input the shape using the entire area of the coordinate input means. Benefits can be obtained.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the basic configuration of the present invention. Here, a is a coordinate input means for inputting information such as figures and characters by inputting coordinates;
b is an output means for outputting the input information input from the coordinate input means a. C is a means for specifying the coordinates of the effective screen that allows the user to freely specify the size of the effective screen of the output means; d is a coordinate input means a based on the coordinate data of the effective screen specified by the specifying means C; This correction means corrects the output coordinate values of the input information so that the input information can be output within the effective screen.

FIG. 2 shows a circuit configuration of an embodiment of the present invention. In FIG. 2, CRT is a display device as an output means, and uses, for example, a compact cathode ray tube display or a liquid crystal display. The CPU is a central processing unit consisting of a microcomputer or the like as a correction means, and performs processing such as controlling and calculating peripheral devices and logical judgments according to the present invention according to the control procedure shown in FIGS. 3 and 4. .

KB is a keyboard as a specifying means, and display device C
It has a function key "ENT" for setting the RT screen effective range.

ROM is a read-only memory, and as shown in Figures 3 and 4.
A control procedure program as shown in the figure, other necessary programs, error messages, etc. are stored in advance. RAM is random access memory, and contains various registers XQ and YO that store information such as the screen effective range entered from B on the keyboard and data such as other calculation results.
, Xl, Yl, X MAX...', etc.

The TAB is a coordinate input device such as a tablet that serves as a coordinate input means, and when the TAB is pressed down on a planar plate with a finger or a stick-like object, the coordinates of that point can be input to the central processing unit CPU. In other words, the coordinate input device UTAB has a switch at each intersection of a plurality of conductive wires provided in the X direction and the Y direction. Based on the received signal, it is determined which position of the switch was pressed, and the coordinates of the pressed point are output according to the determination result. This allows the shape,
Information such as pictures can be output to the display device CRT.

Next, the control procedure of this embodiment for specifying the range of the effective surface of the screen described above will be explained with reference to the flowchart of FIG.

First, when the user presses the human key "ENT" on the keyboard KB to specify the effective range of the screen, the control procedure shown in FIG. 2 is started. In steps 51 and 52, the coordinates (XO, Y
O) and (Xi, Yl) are input from the numeric keypad on the keyboard KB. In the next step S3-S4, a check is made to see if the specified effective range has a practical area.At this time, if the effective range is a line segment, that is, X0=Xl or YO- In the case of Yl, an error message is output on the display device CRT in step S7, and the process returns to step Sl to process the input request again.

If the effective range is correctly a rectangle or a square rectangle, the process proceeds to the next step 55 and 56. Step S5.
In the SS, the X and Y coordinate points in the effective range with smaller values are stored in the areas (registers) XMIN and YMIN of the random access memory RAM, and the coordinate points with the larger values are stored in the area XM of the random access memory RAM.
Store in Ax and YMAx. Now, (XMIN,
YMIN), (XMAX, YMIN), (XM
IN, YMAX), (XMAX, YMAX
) ends the process of specifying the rectangle surrounded by the four points as the effective range of the screen.

Next, referring to the flowchart in FIG. 4, when the effective range of the screen is specified as described above, the coordinate values of the input information from the coordinate input device TAB are corrected to the coordinate values on the effective screen. The control procedure of this embodiment will be explained.

First, in step P1, information on input coordinates (X, Y) is received from the coordinate input device TAB. Next, step P2.
At P3, a correction calculation is performed using the data read from the random access memory RAM to obtain the coordinate m (Xs, Ys) on the screen of the display device CRT. The calculation to be performed at this time is
If the maximum The coordinate point Xs above can be obtained. Similarly, the coordinate point Ys on the screen of the display device CRT can be obtained using the following equation. At this time, the screen pressure [(X
Since the brightness of the point on the display device CRT corresponding to (Ys, Ys) is changed, the point input from the coordinate input device TAB can be confirmed. In addition, the data of the pressed coordinates (x, y) is sequentially stored in the data area (register) DATE in the random access memory RAM as the trajectory of the pressed point on the coordinate input device TAB, and is displayed on the display device CRT. The locus of screen coordinates (Xs, Ys) corresponding to is displayed.

In addition, the maximum x coordinate XTMAX and maximum Y coordinate Y mentioned above
The value of TMAX may be stored in advance in the random memory RAM from B on the keyboard, or may be incorporated into the above-mentioned arithmetic expression as a constant value.

By repeatedly executing the control procedure described above, the input information from the coordinate input device TAB can be kept within the effective range of the designated display screen. In this embodiment, a display device is used as an example of an output means, but it goes without saying that the present invention can also be applied to an output device such as a printer.

[Effects of the Invention] As described above, according to the present invention, in an electronic device having a coordinate input means such as a tablet, input coordinate information from the coordinate input means can be contained within a specified effective screen range. Since the coordinate values are corrected, not only can the figure drawn on the coordinate input means be easily enlarged or reduced to fit the screen of the output means, but also the coordinate range of the coordinate input means can be adjusted to the screen of the output means. Even if you cannot draw a large figure at the time of input, if you specify the effective range of the output screen, you can input the figure using the entire area of the coordinate input means and still be able to draw it from the output screen. There are many advantages such as being able to prevent it from protruding.
