FIG. 5 shows an example of the display screen of the present invention. 85
Is a display screen. In the present invention, one screen is horizontally divided into n equal parts, and the number of divided regions to be displayed is changed as the touch pressure changes. For example, in the first touch, the area gn
Show only. Next, the areas gn and gn-1 are displayed each time the touch pressure is reduced, and the areas gn, gn-1 and gn-2 are displayed when the touch pressure is further reduced. Then, when the finger is released, the entire screen (areas gn, gn-1, ..., G1) is displayed.
Is displayed. At that time, the touch pressure is reduced to reduce the area g.
When the touch pressure is increased in the state where n to area g3 are displayed, the display area decreases and the areas gn to g
4 is displayed. In addition, the display contents are changed along with the change of the display data amount. It is possible to change the entire display screen and display the changed screen while leaving the previous display screen in parallel with the previous screen.

A method of determining the amount of display data according to the present invention will be described with reference to FIGS. The Z coordinate value is obtained in consideration of the touch pressure and the touch pressure difference. That is, in the series of sampled touch data, the strength of the previous touch pressure is f _b , and the strength of the current touch pressure is f _f . And
When the maximum touch pressure F peculiar to the touch panel device and the number of divisions of one screen are n, the Z-axis strength Z = (f _b −f _f ).
・ F _f · n / F However, if f _f is not 0, f
_{When b-} f _f is 0, the Z coordinate value retains the previous value (when the touch is kept and the pressure does not change, the display amount on the screen is not changed).

According to this formula, the Z coordinate value becomes small when the touch pressure is weak and the Z coordinate value becomes large when the touch pressure is strong, considering the change of the touch pressure.
When the Z coordinate value is small, the display data amount is reduced, and when the Z coordinate value is large, the display data amount is increased. Further, as described above, when there is no pressure change in the touched state, the display data amount is not changed. When the touch is released or when the touch pressure is small and the change is small, the full screen is displayed.
In this way, it is possible to reliably change the screen display amount by changing the touch pressure according to the arbitrary maximum touch pressure and the number of screen divisions.

FIG. 6 is an explanatory view of the method of calculating the Z coordinate value of the present invention. FIG. 6 shows that when n = 10 and F = 10, the sampling value of the touch pressure is from 0 to 2, 10, 10, 2,
It shows a change in Z coordinate value and display data amount when changing to 1.

FIG. 7 shows an example of the display data amount determination table of the present invention. In FIG. 7, 72 is an example of a display data amount determination table.

A display screen 86 represents a state in which the entire screen is displayed. A display screen 87 represents a state in which only the uppermost part of the divided area is displayed.

The display data amount determination table 72 associates the display data amount according to the strength of the Z axis. The smaller the absolute value of the Z coordinate value, the larger the amount of display data
The larger the absolute value of the coordinate value, the smaller the display data amount.
The Z coordinate value is larger as the touch pressure and the touch pressure difference are larger.

In FIG. 7, the image data amount G is a data amount for displaying the entire screen (full screen) (Z-axis strength Z = 0 to 10, 0 to -10). G is the state where the touch pressure is the weakest (the state where the pressure is 0 when the finger is released or the touch pressure is small and the pressure change is small), and at this time, 100% is displayed (see the screen display state 86). Z
When the coordinate value is within this range, the image file (see Fig. 3 (b))
The file for one screen (area 1 to area 10) is extracted and displayed. G-g1 is the image data amount obtained by subtracting the data amount of the screen area g1 from the data amount of the full screen when the touch pressure is weak (Z = 10 to 20, -10).
~ -20). When the Z coordinate value is within this range, one screen of file (area 2 to area 10) of the image file (see FIG. 3B) is extracted and displayed. Similarly, G-g1-g2 is the image data amount obtained by subtracting the data amounts of the screen areas g1 and g2 from the full screen data amount (Z = 20 to 30,
-20 to -30). When the Z coordinate value is within this range, the files of area 1 to area 8 are extracted from the image file and displayed.

When the touch pressure is strong, the image data amount is G
-G1-g2-g3-g4-g5-g6-g7-g8-
g9, and the amount of image data displayed at this time is 10% (Z = 90 to 100, −90 to −100, see screen display state 87). When the Z coordinate value is within this range, only the file in area 1 is extracted from the image file and displayed.

By defining the display data amount determination table 72 in this way, the touch pressure is weakened in order,
The amount of display image data increases, the display data decreases by increasing the touch pressure on the way, and the entire screen is displayed by releasing the touch. In addition, since the formula for calculating the Z coordinate value takes into consideration the touch pressure difference, the maximum touch pressure, and the number of divisions as described above, the maximum touch pressure value that differs depending on the touch panel device may be any value. Can also be set arbitrarily.

Although not shown in FIG. 7, when the pressure change is stopped, the previous Z coordinate value is held. In this way, the display data amount is not changed when the change of the touch pressure is stopped during the touch.

The operation of the information processing system and the information processing apparatus equipped with the touch panel device of the present invention shown in FIG. 2 will be described. The user's finger is touched on the touch panel device 51. The receiving unit 61 receives the sampling data of the X coordinate, the Y coordinate, and the touch pressure of the touch area. The touch pressure of the X coordinate and the Y coordinate of the touch area received by the receiving unit 61 is held in the sampling data holding unit 70. The X, Y coordinate analysis unit 62 refers to the touch area coordinate table 71 and determines whether the touch area is a valid area. The Z coordinate analysis unit 63 calculates the Z coordinate value based on the difference between the previous touch pressure and the current touch pressure. Then, the display data amount determination table 72 is referred to for the Z coordinate value of this time, and the display data amount is obtained. Image reading unit 64
Refers to the touch area coordinate table 71 and the display screen number table 73 based on the X and Y coordinates analyzed by the X and Y coordinate analysis unit 62 to obtain the display screen number, and the image data of the display screen from the image file 53 '. The number of files of is extracted as much as the display data amount. For example, area 1 of screen 1
If the area 2 is displayed, the two image files are taken out (see FIG. 3 (b)). Then, the extracted image data is held in the image data holding unit 74. The image transfer unit 75 converts the image data held in the image data holding unit 74 into V
Transfer to RAM76. The display device 54 displays the image data held in the VRAM 76 on the screen.

S2 Input X and Y coordinates and touch pressure,
Obtain X, Y and Z coordinate values. S3, S4, S5 It is determined whether or not the finger is away from the touch screen, and if so, the image data of the target screen is displayed in full screen in S4. If the finger is not released, it is determined in S5 whether the X and Y coordinates are within the touch area.

S6: If it is not within the touch area in S5, an error message is displayed. If it is within the touch area in S7 and S5, the current value of Z coordinate (current touch pressure value) is stored.

S8 The Z coordinate value of this time is calculated based on the difference between the previous touch pressure and the current touch pressure. The image reading data amount (display data amount) is determined according to the S9 Z coordinate value.

S10 Image data (image file) corresponding to the image reading amount is read. S11 The screen number to be displayed next is searched. S12 It is determined whether the display screen of this time is displayed side by side on the display screen up to the previous time or the mode of displaying only the display screen of this time by clearing the display screen of the last time.
If you want to display in parallel with the previous display screen, S1
If the display screen up to the previous time is cleared and only this time is displayed, the process proceeds to S3.

S13 The pointer (indicating the display position on the display screen) of the previous display area is acquired. S14 Count up the display area pointer (specify the area to be displayed this time after the previous display).

S15, S16 It is determined whether the screen to be displayed extends beyond the display screen. If it does not protrude, the initial value of the display area pointer (the uppermost part of the screen) is set in S16, and if it does not protrude from the display screen, the process proceeds to S20.

S17 The display image data is expanded in the VRAM. S18: If the images are not displayed side by side in S12, the initial value of the display area pointer is set.

S19: The previous display screen is erased and S17
The image data is expanded in the VRAM, and the expanded image data is displayed on the display device. S20, S21 It is judged whether or not there is a designation to wait for a display time on the display device. If there is a time wait, the display time is waited in S21 and the subsequent processing is repeated. If there is no need to wait for time, the subsequent processing is repeated without waiting for time.
