[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input display device with a touch panel, such as a facsimile machine, a copying machine,
Alternatively, the present invention relates to an input display device with a touch panel mounted on a workstation or the like.

[0002]

2. Description of the Related Art Conventionally, there is known an input display device with a touch panel in which a transparent touch panel is installed on a display surface for displaying an image and predetermined information can be input by pressing the touch panel surface of the image. The input display device with a touch panel is used as an operation unit of a device such as a facsimile machine, a copying machine, or a personal computer that requires input operation and information display.

An input display device with a touch panel of this type displays a key image (input image) corresponding to input information via a transparent touch panel, detects the pressed coordinates in the transparent touch panel, and responds to the coordinates. It is determined that the key image is selected, and the operator performs an input operation based on the key image. In addition, for example, Japanese
Japanese Unexamined Patent Publication No. 61-114329 describes a method of preventing erroneous input when a touch panel is installed on the display screen of a CRT (Cathode Ray Tube) as an input display device of a computer. From the relationship between the coordinates of the screen and the touch panel at the four corners, the mismatch of the coordinates of the screen and the touch panel due to the bonding error of the touch panel in the case of a large screen, the difference in the viewpoints that differ depending on the operator, or the distortion of the curvature due to the shape Corrected to prevent erroneous input.

[0004]

However, in such a conventional input display device with a touch panel,
The touched position (coordinates) of the touch panel with respect to the key image may be the center of the key image or a position displaced from the center so as not to hide the key image with the fingertip. Wrong input occurs. Therefore, the input effective area for the key image is sufficiently larger than the fingertip, or a dedicated pen is used. In recent years, the number of operation items has increased due to multi-functionalization in recent facsimile machines, copiers, etc., so that the screen becomes large (it is not as large as a CRT).
However, when a key image larger than the fingertip is displayed, there is a problem that the operation can be complicated because only a small number of selection key images can be displayed on one screen. Further, in the case of inputting with a dedicated pen, this must be used for operation, and there is a problem that input becomes impossible if it is lost. These problems also apply to handy type devices.

Further, from the above problem, there is a problem that long information such as the name of the other party or a telephone number cannot be displayed as a key image, which has been realized by scrolling in the related art. There was a problem of becoming high. Further, the error of the pressing coordinates for key image varies depending on the display position, JP
In the erroneous input prevention method described in Japanese Patent Laid-Open No. 61-114329, since the coordinates of the touch panel with respect to the entire screen are corrected, the position of the input effective area cannot be corrected for each size of the key image, and the key There is a problem that erroneous input that occurs due to a small image cannot be prevented.

Therefore, according to the present invention, the input effective area is corrected to a position according to the operator to prevent erroneous input and to reduce the area of the input image, thereby improving the displayability and operability. The purpose of this is to improve the versatility and the reliability of the input image by supporting the flatness and the display position of the input image.

[0007]

For the purposes achieved SUMMARY OF THE INVENTION, invention of claim 1, wherein an image display means for displaying the input image, the installed data Tchipa on the display surface of the image display means <br /> panel and, and a coordinate detecting means for detecting the touched coordinates to the touch panel, a touch panel with input display device for touch input an input effective region of the corresponding the touch <br/>, channel to the input image there, the image control means for displaying a plurality of kinds of correction image having an area corresponding to the input image on the image display means, said touch panel for the detected coordinates and the correction image by the coordinate detection means Correlation detection means for detecting the correlation with the position for each correction image, and the position of the input effective area of the input image is corrected based on the correlation detected by the correlation detection means in the corresponding correction image. A corrective position correcting means is provided.

According to a second aspect of the present invention, flatness detecting means for detecting the flatness ratio and flattening direction of the input image, and correlation correcting means for correcting the correlation based on the detection information by the flattening detecting means, Is provided. According to a third aspect of the present invention, the image control means is
The correction image having the same area is displayed at different positions on the display surface of the image display means, and the position correction means determines the position of the input effective area of the input image according to the input image. The correction image displayed at the different position is configured to be corrected based on the correlation detected by the correlation detecting means.

Here, the flatness ratio means a ratio of widths of images in the X-axis direction and the Y-axis direction on the display surface of the image display means. Even if the areas of the input image and the correction image do not completely match each other, the position correction means may use, for example, the correlation detected in the correction images having similar areas or the correction images having different areas. It goes without saying that the position of the input effective area of the input image may be corrected based on the proportional relationship of the detected correlation.

[0010]

According to the first aspect of the present invention, the image control means causes the image display means to display a plurality of types of correction images each having an area corresponding to the input image, and the touch coordinates corresponding to each correction image are coordinate detection means. Detected by the
The correlation detection unit detects the correlation between the touch coordinates and the position on the touch panel. Then, the position of the input effective area of the input image is corrected based on the correlation detected in the corresponding correction image. Therefore, the position of the input valid area is corrected to a position corresponding to the area of the input image touched by the operator, and when the input is made, the input valid area is touched , and erroneous input is prevented.

According to the second aspect of the present invention, the flatness ratio and flattening direction of the input image are detected by the flatness detecting means, and the correlation detected by the corresponding correction image based on the detection information is detected by the correlation correcting means. Will be fixed. Therefore, the position of the input effective area of the input image is corrected according to the flatness rate and flattening direction, and the influence of the shape of the input image is eliminated.

[0012] In the present invention of claim 3, wherein the correction image area on the display surface at different positions of the image display means are the same is displayed by the image control means, touch These per correction image
The correlation between the H- coordinate and the position of the touch panel is detected by the correlation detecting means. Then, the position of the input effective area is corrected based on the correlation detected in the correction image corresponding to the display position of the input image. Therefore, the position of the input effective area is corrected not only according to the area of the input image but also according to its display position.

Scanner 15 and plotter
The various sensor groups 23 and various motor groups 24 attached to the main body of the facsimile apparatus including 17 and the I / O control section 25 which is interposed between the various motor groups 24 and controls these signals are connected to the ROM 12 The above-mentioned respective parts are controlled in accordance with the control program stored therein. In addition, 26 is a telephone that the facsimile device is equipped with, and 27 is A
It is a DC power supply unit that converts the C power into a direct current and supplies it to each of the above units.

As shown in FIG. 2, the operation board unit 22 has a display unit 32 to which a translucent touch panel (so-called transparent touch panel) 31 is attached and which displays an image on an LCD, and a selected setting condition such as reading. LED group 33 that displays information such as device and device abnormalities by a plurality of LEDs 33a
Dial key 34a, various function selection keys 34b, copy key 34c, start key 34d, and stop key 34.
and a key matrix section 34 in which e is arranged, and the display section 32 is connected via the display control section 35 and the LED group 33.
The key matrix section 34 is connected to the MPU 11 via the operation port control section 36. The display unit 32 is configured to be controlled by the display control unit 35 to display an image. For example, the display control unit 35 displays at least one type of image read by the MPU 11 from the HDD 14 at a position corresponding to the image. To be done. The LED group 33 is turned on / off by the operation port control unit 36 based on the instruction signal sent from the MPU 11. The key matrix section 34 is adapted to select a setting mode for carrying out the present invention by a selection key 34b, for example, a mode key 34b, and the selection signal is sent to the MPU 11 by the operation port control section 36. The display unit 32 includes a backlight 37, and the backlight 37 is connected to and controlled by the operation port control unit 36.

When the touch panel 31 is of a digital type, a key image (input image) matched to the coordinates of the touch panel 31 must be displayed on the display unit 32, so that the degree of freedom of the key image is limited. Since it becomes expensive to manufacture the touch panel 31 itself according to the key image so as to increase the degree of freedom, an inexpensive analog contact type is adopted, and the key image is pressed to selectively input it. The pressed coordinates at this time and the screen coordinates of the display unit 32 are adjusted in advance and pasted together. As shown in FIG. 3, the coordinates of the touch panel 31 are formed by the transparent electrodes 38a and 38b which extend in the X-axis and Y-axis directions and are drawn to the outside.
A voltage supply section 40 and an A / D converter 41 are connected to a and 38b through a changeover switch 39, and the changeover switch 39
An I / O controller 25 is connected to the touch panel controller 42 via a touch panel controller 42.

In this touch panel 31, the switching of the connection by the change-over switch 39 is controlled by the touch panel control section 42 so that the voltage of the voltage supply section 40 is the X-axis electrode 38.
The voltage applied to the a or Y axis electrode 38b alternately and detected by the other of the electrodes 38a and 38b is digitized by the A / D converter 41 and sent to the MPU 11 as coordinate data of the pressed coordinate. . And MP
U11 monitors the state of the touch panel control unit 42 so that the coordinate data from the A / D converter 41 receives the data of the electrodes 38a,
It is possible to determine which one of 38b, and since the coordinates of the touch panel 31 and the coordinates of the display unit 32 match, it is possible to detect the pressed coordinate from the coordinate data and determine that the corresponding key image has been input. You can For example, when the voltage supply unit 40 is connected to the X-axis electrode 38a of the touch panel 31 by the changeover switch 39, the voltage difference between the X-axis electrodes 38a [V ⁺ −V ⁻ (V ⁺ > V ⁻ )]. Is added, at this time, [Vmax-Vmin] is applied between the electrodes 38b on the Y-axis.
(V ⁺ >Vmax>Vmin> V ⁻ )], the coordinate voltage corresponding to the pressed position (pressed coordinate) is observed. This MPU11
Is the full scale of the A / D converter 41 [Vmax-Vm
in] or more, the coordinate data of the entire surface of the touch panel 31 can be known by numerical values. That is, the display unit
The numeral 32 constitutes an image display means, and the MPU 11 constitutes a coordinate detection means.

The pressed coordinates detected by the touch panel 31 may be a position corresponding to the center of the key image displayed by the display unit 32 depending on the operator, or a position outside the key image in some cases. . For example, a key image may display characters or the like indicating its content (function) inside, so some operators shift the character image to the lower left or right side depending on the dominant hand so that the character is not hidden by the fingertip. In the case of a small key image, it may be outside the effective pressing area (effective input area) where it is determined that the key has been pressed, resulting in an erroneous input and an erroneous operation due to non-input or input of another key image. . In the conventional facsimile apparatus, this problem has been solved by making the key image sufficiently larger than the fingertip.

Therefore, the MPU 11 of the present embodiment corrects the position of the pressing effective area with respect to the key image on the basis of the correlation with the pressing coordinates corresponding to the operator for each area of the key image. , Key image displayed in normal input mode (hereinafter also referred to as input key image)
As an example of a rectangular display that is frequently used as, when the setting mode is selected by the mode key 34b of the operation board unit 22, the area is small, as shown in FIG.
Medium and large buttons A to C are used for correction key image (correction image)
As read out from the HDD 14, the display control unit 35 displays it on the display unit 32, and prompts the operator to press the buttons A, B, and C in this order, and the pressed coordinates detected by each and the buttons A, B, and C in the touch panel 31. The coefficient α in the X-axis direction and the coefficient β in the Y-axis direction are calculated from the ratio (correlation) of the shift amount according to the size of the image with respect to the center coordinate (position) of the button A group, B group, C group. The HDD 14 is rewritten by calculating (correcting) the position of the effective pressing area for each of the input key images divided into two, using the coefficients α and β. That is, MPU11
Constitute image control means, correlation detection means, and position correction means. By displaying the buttons A to C in accordance with the minimum, middle, and maximum sizes of the input key image, the position of the effective pressing area can be corrected with high accuracy, and the display unit 32 has You may make it display on the basis of the size of a fraction of the display surface. Also,
The correction key image is not limited to the three types of buttons A to C,
The input key image may be subdivided into areas and displayed so as to correspond to each area.

Next, the above-mentioned correction by the MPU 11 will be concretely described with reference to the flow chart shown in FIG. Here, with respect to the key D (input key image) whose pressing effective area is the image display area (outer edge of the image), the center of the pressing effective area is moved in parallel using the coefficients α and β to change the position. A simple correction will be described. First, when the setting mode is selected, after displaying the buttons A to C on the display unit 32, it is confirmed whether or not the button A has been pressed within a predetermined time by detecting the pressed coordinates (step P1), and pressing. If not, "Please press button A." is displayed (step P2), and when pressed, the detected pressing coordinates (XT, YT) are stored in the HDD 14 (step P2).
3).

Next, as shown in FIG. 6, with respect to the pressed coordinates (XT, YT), the center coordinates of the button A on the touch panel 31 are (XA, YA), and the X-axis direction of the side length is A.
The coefficients αA and βA, which are the ratios of the amounts of deviation between the center coordinates and the pressing coordinates with respect to the length of the side, where AY is the X and Y axis directions, are calculated from the following equations (step P4), and the coefficients αA and βA Is stored in the HDD 14 (step P5).

ΑA = (XA−XT) / AX (1) βA = (YA−YT) / AY (2) At this time, in step P 1, “button A pressed?”
Since it is distinguished from the presses on the buttons B and C by confirming whether or not, for example, the coefficient α in the above equations (1) and (2) is
When the magnitudes of A and βA are equal to or larger than a predetermined value (for example, 2 or more), it is determined that the pressed position is largely deviated, it is determined that an input error by the operator occurs, and the correction process is continued as it is. Can be prevented.

Then, as shown in FIG. 7A, the key D
When the pressing effective area D2 of the HDD is initially set in the HDD 14 and overlaps with the image D1, the center coordinates are (XD, YD), the X-axis direction of the side length is DX, and the Y-axis direction is DY. The center coordinates (XD, YD) of the effective area D2 are calculated by the following equation (x
D, yD) and the position of the effective pressing area D2 is shown in FIG.
As shown in (b), it is translated and corrected (step P6).

XD = XD−αA · DX (3) yD = YD−βA · DY (4) Thereafter, the effective pressing area D in the HDD 14 corresponding to the key D
The position of 2 is rewritten to the position after conversion and stored (step P7). The process of steps P6 and P7 is the same as button A.
After performing the key D of the group, the buttons B group and C group are sequentially processed in the same manner to rewrite the position of the effective pressing area in the HDD 14 together with the coefficients αB, βB, αC and βC. Therefore, the data in the HDD 14 is rewritten as shown in FIG. 8, and the positions of the effective pressing areas of the buttons A group, B group, C group, and all keys are translated (corrected), and the correction is performed in the normal input mode. The operator presses the vicinity of the center of the pressed effective area, which prevents erroneous input.

As described above, in this embodiment, when the setting mode is selected, the correction key images of the buttons A to C having different areas are displayed on the display section 32, and the buttons A to C are pressed in the touch panel 31. The position (pressed coordinate) is detected, and the coefficients αA, βA to αC, βC are calculated from the deviation of the pressed coordinate with respect to the center coordinate in each touch panel 31. Then, the positions of the effective pressing area D2 correspond to the image area of the key D, and the coefficients αA, βA, and α of the buttons A, B, and C are grouped.
B, βB, αC, βC are used and corrected. for that reason,
The positions of the pressing effective areas D2 of the buttons A, B, C, and all keys D used in the normal input mode are corrected according to the image area, and in the normal input mode, regardless of the image area of the key D. That is, even if the image area is small, the vicinity of the center of the effective pressing area D2 is pressed, and erroneous input is prevented. Therefore, the effective pressing area D of the key D
It is not necessary to unnecessarily increase the size of 2, and the pressing effective area D2 of the key D can be reduced in area. As a result, various keys D can be laid out in a single screen without the need for a dedicated pen or the like, and the displayability and operability can be improved.

Although the same applies to the embodiments described below, it goes without saying that the rectangular input image described in this embodiment is an example and can be applied to input images of other shapes. None, for example, in the case of a circle, the above (1)
The side length of equation (2) should be the radius of the circle.
The same processing can be performed when circles and the like are mixed.

Furthermore, the center of the input image and the spread of the image, that is, the rate of change of the amount of deviation with respect to the side length and radius are obtained, and the position of the input effective area is determined by the rate of change without dividing the input image by its area. May be corrected individually, which is preferable because the correction can be performed with high accuracy when the sizes of the input images vary. If the number of input images is small, the same correction images as all the input images are displayed without calculating the correction coefficient.
The effective pressing area may be moved and corrected according to the amount of deviation (correlation) between the position (not limited to the center coordinates) and the pressed coordinates.

Next, FIG. 9 is a diagram showing an example of a facsimile apparatus equipped with a second embodiment of an input display device with a touch panel according to the present invention.
It corresponds to the described invention. In addition, in this embodiment, since the configuration is substantially the same as that of the above-described embodiment, the configuration is omitted. First, the configuration will be described.

The MPU 11 of this embodiment detects the flatness ratio and flattening direction of the input key image in addition to the same processing as that of the first embodiment, and correlates with the pressing coordinates corresponding to the operator with respect to the area of the image. To correct the position of the effective pressing area of the input key image. here,
Since the shape of the input key image may be selected by pressing and inputting, for example, a rectangular shape is generally a square shape, and an elliptical shape is generally a circular shape having a small flatness. However, in recent years, there are some images that are considerably long in the lateral direction such as the display of the other party of the electronic telephone directory function. When the pressing effective area of the long input key image is corrected by the same processing as that of the first embodiment, when the end in the long direction becomes the pressing coordinate in the setting mode, it becomes large in that direction. The area that moves and overlaps the image becomes smaller. Therefore, in the present embodiment, the position of the effective pressing area of such a long input key image is properly corrected.

Therefore, the MPU 11 of this embodiment has the above-mentioned first
After the coefficients α and β are calculated by performing the same processing as in the embodiment, the ratio of the lengths of the vertical and horizontal sides of the input key image (flatness ratio)
And the flattening direction is detected, and when the ratio is a predetermined multiple or more (for example, three or more), the coefficient α or β in the flattening direction is corrected to zero, and the position in the long direction of the effective pressing area is moved. Correct without That is, the MPU 11 also constitutes flatness detecting means and correlation correcting means.

Next, the above-mentioned correction by the MPU 11 will be concretely described with reference to the flow chart shown in FIG. Here, with respect to the key E (key image for input) which has a long image in the X-axis or Y-axis direction with the image display area as the pressing effective area, the coefficients α and β calculated in the first embodiment are set. A simple correction in which the correction is performed and the center of the pressing effective area is moved in parallel to change the position will be described. In the initial setting of the HDD 14, the effective pressing area of the key E is located at the center coordinates (XE, YE) while overlapping the image D1, and the X-axis direction of the side length is EX and the Y-axis direction is. Let's say EY.

First, steps P1 to P of the first embodiment described above.
5 and set the pressed coordinates (XT, YT) of button A to HD.
After being stored in D14, the coefficients αA and βA of button A are calculated and stored in the HDD 14. Then, the center coordinates (XE, YE) of the effective pressing area of the key E and the side lengths EX and EY are set to the HDD.
If the side length in the X-axis direction is AX≈EX or the side length in the Y-axis direction is AY≈EY, it is determined to be included in the button A group and the corresponding number is read. A variable m (n = 1, 2, 3, ... N) that maximizes n is prepared (step P11), and the flatness of the key Em and the flattening direction are in a relationship of EXm ≧ 3 · EYm (side length). Is 3 times or more) (step P12), and when the side length ratio is 3 times or more, the coefficient αAm is set to αAm = 0 (step P13). If the side length ratio is less than 3 times in step P12, it is confirmed whether the flatness of the key Em and the flattening direction have a relationship of EYm ≧ 3 · EXm (step P1
4) When the ratio of the side length is 3 times or more, the coefficient βA
m is set to βAm = 0 (step P15).

Then, the center coordinates (XEm, YEm) of the effective pressing area of the key E are calculated by the above equations (3) and (4) as (xEm,
yEm) and the position of the effective pressure area is corrected and the HDD 14
Is rewritten and stored (step P16). After that, it is confirmed whether the variable m becomes m = n (step P17), and the variable m
Is m ≠ n and all the keys E included in the button A group have not been corrected, the variable m is set to m = m + 1 and the process returns to step p12 to repeat the same processing. Then, when the correction process of the key E included in the group A is completed, the button B is pressed.
Group C and group C are sequentially processed in the same manner, and coefficients αB, βB,
After obtaining αC and βC, the HDD 14 is rewritten. Therefore, the key E used in the normal input mode is X-axis or Y-key.
If it is long in the axial direction, the position of the effective pressing area is not corrected in the long direction, and even if the long-side end of the key E becomes the pressing coordinate in the setting mode, that direction is not corrected. The position of the effective pressing area does not move significantly.

As described above, in this embodiment, in addition to the effects of the first embodiment, when the setting mode is selected, the ratio of the vertical and horizontal sides of the key E and the lengthwise direction are detected, and the ratio is 3. If it is more than twice, the coefficient for correcting the effective pressing area in the longitudinal direction is corrected to zero. Therefore, when the key E is long, it is possible to prevent the position of the pressing effective region from being largely corrected in the lengthwise direction and to reduce the portion overlapping the image. Therefore, the problem that the key E is not pressed even though the key E is pressed in the normal input mode does not occur. As a result, the limitation of the correction due to the shape of the key E can be eliminated, and the versatility can be improved.

As another aspect of this embodiment, although not shown, for example, the side of the key E in the X-axis direction is Y.
When it is three times or more of the side in the axial direction, the coefficient αA obtained from the above equation (1) is corrected as in the following equation, and αA ′ = (EY / EX) · αA (1) ′ This coefficient αA 'is used in the above equation (3) as the following equation: DX' = XE-αA '· EX (3)' A correction for moving the position of the effective pressing area of the key E in parallel is performed. It can also be configured to do so.

Further, in addition to the area of the pressing effective area in the first embodiment described above, a plurality of shapes having different flatness rates are displayed on the display section 32, and the buttons A group, B group and C group are further changed to the flatness rate. Accordingly, the position of the effective pressing area may be subdivided and corrected. Next, FIG. 10 to FIG. 12 are views showing an example of a facsimile machine equipped with a third embodiment of the input display device with a touch panel according to the present invention,
This embodiment corresponds to the invention described in claim 1 or 3. Since the present embodiment has a configuration similar to that of the first embodiment described above, a block diagram showing the configuration is omitted.

First, the structure will be described. MPU of this embodiment
11, the correction key image having the same area as the input image is displayed at different positions of the display unit 32, and the image size of the center coordinate and the pressed coordinate in the touch panel 31 is displayed for each display position. The position of the effective pressing area of the input key image corresponding to each area and display position is corrected based on the ratio (correlation) of the shift amount. Here, the pressed coordinates for the input key image are less affected by the display position when the display unit 32 has a small screen, but when the image area is small and the display unit 32 has a large screen, it is determined by the operator. The amount of deviation from the effective pressing area differs for each display position, and the correction of the position of the effective pressing area may not be sufficient only by the same processing as in the first embodiment. Therefore, in this embodiment, the display unit 32 is configured to appropriately correct the position of the effective pressing area according to the display position of the input key image on the large screen.

Therefore, in the MPU 11 of the present embodiment, when the setting mode is selected, for example, it is considered that the change amount of the shift amount between the pressing effective area and the pressing coordinate is large depending on the display position of the input key image. 32 corners and center, Figure 10
, The buttons A, B, and C are displayed by the display control unit 35 for each screen of the display unit 32, and the operator is urged to press the buttons A, B, and C according to the order (1 to 5) in the buttons A, B, and C. Using the ratio of the amount of deviation between the pressed coordinates detected in each case and the center coordinates in the touch panel 31 according to the size of the image, the display unit 32 shows the correlation between the pressed coordinates and the center coordinates.
The distribution function γ (X) in the X-axis direction and the distribution function δ (Y) in the Y-axis direction of the ratio of the shift amount are created for each of the four quadrants of the display screen of, and the input key image of the input key image input in the normal input mode is created. The position of the effective pressing area is calculated (corrected) for each of the buttons A group, B group, and C group using the distribution functions γ (X) and δ (Y).
Rewrite. The correction key image displayed on the display unit 32 in the setting mode is not limited to the buttons A to C, and is not limited to the four corners and the center thereof. It goes without saying that the correction accuracy may be improved by displaying other than the above.

Next, the above-mentioned correction by the MPU 11 will be concretely described with reference to the flow chart shown in FIG. Here, the center of the key F (key image for input) whose display area of the image is the effective pressing area is the distribution function γ (X),
A simple correction in which the position of the effective pressing area is changed by performing parallel movement using δ (Y) will be described. First, when the setting mode is selected, after the buttons A1 to A5 are displayed on the display unit 32, it is confirmed whether or not the button A1 is pressed within a predetermined time by detecting the pressed coordinates (step P2).
1) If it is not pressed, the message "Please press button A1." Is displayed (step P22), and when pressed, the detected pressing coordinates (XT1, YT1) are stored in the HDD 14 (step P23).

Subsequently, the buttons A2 to A5 are subsequently processed in the same manner as in steps P21 to P23, and the buttons A2 to A5 are processed.
5 Pressed coordinates (XT2, YT2)-(X
T5, YT5) is stored in the HDD 14 (steps P31 to P6)
3). Next, the center coordinates of the buttons A1 and A5 are (XA1,

At this time, similarly to the above-described first embodiment, it is possible to obtain the coefficients α and β of the buttons A1 and A5 and correct the position of the effective pressing area of the key F close to the display position.
Since it is considered that the distributions of the coefficients α and β change between 1 and A5 according to a predetermined rule, the center coordinates and the pressed coordinates of the side length of the virtual button A ′ corresponding to the position in this quadrant are pressed. It is also possible to make corrections based on the distribution (correlation) of the ratio of the deviation amount. Its distribution function γ (X),
δ (Y) is the central coordinate of (X) when the effective pressing area of the key F overlaps the image at the time of initial setting in the HDD 14.

[Equation 1] Then, the center coordinates of the effective pressing area of the key F are calculated by the following equations in which the distribution functions γA1 (XF) and δA1 (YF) are replaced with the coefficients α and β of the equations (3) and (4) of the first embodiment. (XF,
YF) is converted into (xF, yF), and the position of the effective pressing area is corrected (step P66).

XF = XF−γ (XF) · FX (3) ”yF = YF−δ (YF) · FY ... (4)” After that, the pressing of the HDD 14 corresponding to the key F is effective. The position of the area is rewritten to the converted position and stored (step P
67). The processes of steps P66 and P67 are similarly performed for the buttons A1 and A5 of the button A group and the key F for each quadrant composed of the buttons A2 to A4 and A5, and then for the buttons B group and C group. To the HDD 14 together with the respective distribution functions γ (XF) and δ (YF).
Rewrite the position of the effective pressing area inside. Therefore, H
The data in DD14 is rewritten as shown in FIG.
The positions of buttons A, B, C, and all keys used in the normal input mode are moved in parallel (corrected) to the positions corresponding to the image area and display position,
In the normal input mode, the operator presses the vicinity of the center of the corrected effective pressing area, and it is possible to prevent erroneous input.

As described above, in this embodiment, when the setting mode is selected, the buttons A to C (correction key images) having different areas are displayed in the four corners and the center of the display screen of the display unit 32 for each area. , The pressed coordinates pressed in the touch panel 31 are detected for each of the buttons A to C and for each display position, and are distributed in each quadrant of the display screen from the deviation of the pressed coordinates with respect to the central coordinates in the touch panel 31. Function γ
(X) and δ (Y) are calculated. Then, the position of the effective pressing area of the key F is for each quadrant, and the distribution function γ for each of the buttons A, B, and C corresponding to the image area thereof.
(X) and δ (Y) are used for correction. for that reason,
The positions of the pressing effective areas of the buttons A, B, C, and all the keys F used in the normal input mode are corrected according to the image area and display position, and the area and the display of the key F in the normal input mode are corrected. Irrespective of the position, the vicinity of the center of the pressing effective area is pressed, and erroneous input is prevented. Therefore, the operational effects of the first embodiment described above can be obtained, and the reliability can be improved.

According to the first aspect of the invention, the position of the input effective area is corrected based on the correlation with the touch coordinates corresponding to the area of the input image. It is possible to correct the position touched by the operator according to the area of the image, and it is possible to prevent erroneous input even for a small input image. Therefore, it is not necessary to unnecessarily increase the size of the input image, and the area of the input image can be reduced. Therefore, many input images can be laid out in one screen without the need for a dedicated pen, and the displayability and operability can be improved.

According to the second aspect of the invention, the correlation with the touch coordinates for correcting the position of the input effective area of the input image is corrected according to the flatness ratio and flattening direction. It is possible to eliminate the limitation on whether or not the correction can be performed depending on the shape, and it is possible to improve versatility. According to the third aspect of the invention, the position of the input effective area is corrected based on the correlation with the touch coordinates corresponding to not only the area of the input image but also the display position. It is possible to correct the position to be touched by the operator according to the display position of the business image, and the reliability can be improved.
