2. Description of the Related Art Conventionally, a touch panel is provided as a position reading means on the entire surface of a display device, and when a user touches the touch panel, an input position designated by the user is read, and processing related to that position is performed. An information processing device is known. Such information processing devices are configured so that the user indicates the input position using, for example, a fingertip, but the tip of a human finger is generally larger than the minimum readable area set for the position reading means. Furthermore, the resolution of the position that the user can specify is limited by the area of the fingertip.

0003

[Problems to be Solved by the Invention] However, in the conventional information processing apparatus described above, when a user indicates an input position, the resolution is limited by the area of the tip of the indicating means (fingertip, etc.) used. If it is difficult to accurately specify a region or point smaller than this, there will be a large number of erroneous inputs, resulting in a reduction in processing efficiency.

[0004] Furthermore, when it is necessary to accurately specify an area or point smaller than the area of a user's fingertip in order to perform a certain process, for example specifying a range of an area,
It is necessary to use a tool whose tip area is smaller than the area of the fingertip, such as the tip of a pen, and if the user is also using other input methods such as a keyboard, the user is forced to change the pen. There was a drawback.

An object of the present invention is to focus on such conventional problems, and in order to solve them, to provide an information processing device that can obtain a highly accurate input position without being limited by the area of the tip of the user's pointing device. It's about doing.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a display means for displaying image information, and a display means provided on the front surface of the display means, so that a position touched by a user can be detected from the display means. a position specifying means for reading, a means for outputting coordinate values of the position based on a read signal from the position specifying means, and a display area including the position being limited and enlarged based on the output coordinate values of the position. and means for outputting the enlarged display area to a window on the display means, and the position of the enlarged display area displayed on the window is read by the position specifying means. Features.

[0007]

[Operation] According to the present invention, when the user specifies the position by touching a designated reading point to be enlarged via the position specifying means as necessary, a limited area including that position is displayed on the window. . Therefore, the user can specify the input position by touching the specified point again in the limited area that includes the specified point enlarged and displayed in the window, and the user can specify the input position by touching the specified point again. The contact means can point at least a point smaller than the tip of a fingertip, for example.

[0008]

[Examples] Examples of the present invention will be described below based on the drawings.
This will be explained in detail and specifically.

FIG. 1 is a block diagram showing the configuration of the present invention. Here, 1 is a display for displaying characters, symbols, images, etc. using a CRT or liquid crystal, and 2 is a reading device (reader) attached to the display 1, which is a display device, to read the indicated position touched by the user with a fingertip, etc. (hereinafter referred to as a touch panel). 3 has a central processing unit CPU4, and based on the read signal output from the touch panel 2,
An information processing unit that performs various processes; 5 is a storage device ROM that stores programs for implementing various processes; 6 is a storage device RAM for reading/writing; When it receives an output signal, it converts it into a positional coordinate on the display 1 according to an instruction based on the signal, and outputs the positional coordinate to each part according to a request from the CPU 4. Thus, when a display is commanded via the CPU 4, the display signal generating device 8 produces a corresponding display on the display 1 using an output signal according to the command.

In the information processing apparatus configured as described above, when a user touches the touch panel 2 with a fingertip, a read signal is output from the touch panel 2 to the information processing section 3 according to the touched position. In this way, the information processing section 3 outputs the read signal as a position coordinate value on the touch panel interface section 7 in response to the position coordinate output request from the CPU 4, and the information processing according to the program to be described later is executed by C.
This is done by PU4. Here, the position coordinate output request from the CPU 4 may be configured to be issued at specified predetermined time intervals (so-called sampling period) using, for example, a timer that counts clocks.

Next, as shown in FIG. 2, when the user specifies a position on the image displayed on the display 1 via the touch panel 2 with a fingertip, the input position is set to CP.
The operation procedure up to confirmation by U4 will be explained with reference to FIG.

As mentioned above, the information processing apparatus of the present invention is equipped with a well-known enlargement function that can enlarge a part of the display screen and display it in a window. As shown in (A) of 3, the fingertip 1 is placed on the touch panel 2 at the position of the switch 10 displayed on the display 1.
A command can be issued by pressing 1. Also, in Figure 3 (
Image 1 displayed on display 1 as shown in B)
2, if you press the desired position of the image 12 on the touch panel 2 with your fingertip 11 following the above-mentioned enlargement command, the screen will be divided into 16 parts approximately centered on the specified position (
) 13 indicated by a broken line is enlarged and displayed in the window 14 as shown in FIG. 3(C). However, this window display is displayed as a four-split screen that does not include the point previously designated to be pressed by the fingertip 11, and the magnification ratio is 2×2.

First, in step S1 of FIG. 2, it is determined whether or not an enlargement command has been input using the command switch 10. If it is determined that there has been an input, it is assumed that the switch 10 has been pressed, and the process proceeds to step S2, where enlargement is specified. Ru. Then, in the next step S3, the fingertip touches the enlarged position as shown in FIG. The frame screen 13 also moves along with it. Also, fingertip 1
1 from the touch panel 2, an enlarged screen 14 centered on the designated point is displayed in the window 13, as shown in FIG. 3C. Therefore, it is possible to touch a desired input position with the fingertip 11 on this enlarged screen 14 and input and determine that position (step S4).

If you wish to further enlarge the enlarged screen 14 shown in FIG. 3(C) to clarify the input position, return to step S1 from step S3 and press the command switch 10 for enlargement again. do it. Then, on the enlarged screen 14 shown in the window 13 of (C),
Touch the designated position again with the fingertip 11 as shown in D) (
As a result of steps S2 and S3), the re-enlarged screen 24 is displayed by the second window 23 at a position that does not overlap with the previous window 13, as shown in (E) of the figure. Therefore, after this, the input position can be determined (step S4) by pressing the fingertip 11, as described above regarding the re-enlargement screen 24.

In the embodiments described above, the enlargement range specified when enlargement is specified is 16 divisions of the entire original screen, but the enlargement range is not limited to this. In short, it is sufficient that the area is a limited area suitable for expansion. In addition, in the above example, the enlarged image was set to be 2x2 times (4 times the area ratio), but this enlargement rate also depends on the resolution of the display device itself, that is, the pixel density. It only needs to be set appropriately. Furthermore, in the above-mentioned embodiment, as a preferred example, a person's fingertip is used to press a specified position on the touch panel, but not only the fingertip but also other indicating instruments such as a pen tip can be used to display and input the position by following the same procedure. Needless to say, a decision of the following can be obtained.
