[Prior art]
2. Description of the Related Art Conventionally, document creation application software (so-called word processing software) that operates on a personal computer has a function of enlarging / reducing an image object displayed on a screen to a desired magnification for easy viewing. A typical example is that a list box for selecting an enlargement / reduction ratio is displayed on a menu bar on the screen (see Non-Patent Document 1, for example). According to this, when the user points to the list box with the mouse and selects a desired magnification, the origin position on the screen (in general, in the word processor software, the upper left corner position of the word processor editing screen) is used as a reference. The entire screen is enlarged or reduced at the selected magnification.
[0003]
Therefore, when expanding an arbitrary image object from 100% to 120%, for example,
(1) Set the upper left corner position of the image object to the origin position.
(2) Select “120%” using the mouse to select the enlargement / reduction ratio selection list box on the menu bar.
By continuously performing the above operations, the target image object can be enlarged and displayed at a desired magnification (in this case, 100% → 120%).

Single-tap operation near the right side of, and single-tap operation near the left side of the rectangular pressing surface 291. Also in this case, “near” means, for example, a region that enters a third of the rectangular pressing surface 291 when the rectangular pressing surface 291 is equally divided into three in the longitudinal direction, and the vicinity of the right side is the right third of the rectangular pressing surface 291. The vicinity of the left side is the left side 1/3 of the rectangular pressing surface 291.
[0016]
<Double tap operation>

(E) is a double tap operation near the upper part of the rectangular pressing surface 281, (f) is a double tap operation near the center of the rectangular pressing surface 281, and (g) is a lower part of the rectangular pressing surface 281. This is a double tap operation to the vicinity. Like the single tap operation, “near” is, for example, 1/3 when the longitudinal touch surface of the first press sensor 28 is divided into three equal parts. Can be an area.
[0017]
Although not shown, the same applies to the case of the second press sensing unit 29. The double tap operation is an operation of pressing the rectangular pressing surface 291 twice with a fingertip U within a predetermined time. A double tap operation near the right side of the pressing surface 291 and a double tap operation near the left side of the rectangular pressing surface 291 are included. Also in this case, “near” means, for example, a region that enters a third of the rectangular pressing surface 291 when the rectangular pressing surface 291 is equally divided into three in the longitudinal direction, and the vicinity of the right side is the right third of the rectangular pressing surface 291. The vicinity of the left side is the left side 1/3 of the rectangular pressing surface 291.
[0018]
<Single tap operation + slide operation>
The single tap operation + slide operation is an operation of shifting after pressing the rectangular pressing surface 281 with the fingertip U once as shown in (h) and (i). (H) and (i) have different tap positions and shifting directions. That is, (h) is a single tap operation near the upper part of the rectangular pressing surface 281 and then a downward shift operation, and (i) is a single tap operation near the lower part of the rectangular pressing surface 281, This is an operation for shifting upward. Although not shown, the same applies to the case of the second press sensing unit 29.

[0019]
FIG. 3 is a simplified internal block configuration diagram of the electronic device 20. In this figure, 30 is a CPU (determination means, redrawing means) for controlling each processing operation of the electronic device 20, 31 is a RAM that functions as a work memory in executing each operation processing, and 32 is a processing performed by the CPU 30. ROM for storing various software, 33 a display control unit for controlling the display mode of the flat display panel 22, 34 a transparent touch panel covering the display screen of the flat display panel 22, and 35 for detecting touch coordinates of the touch panel 34 A coordinate detection unit (coordinate detection means), 36 is an input / output interface, and 37 is a bus.
[0020]
The CPU 30 loads and executes software resources (basic programs, various application programs, etc.) written in advance in the ROM 32 to the RAM 31 and executes the first press sensing unit 28 and the second press via the input / output interface 36. Hardware resources such as the CPU 30 while capturing input signals from the processing unit 29 and other input devices 36 (such as various operation buttons 23 to 27) and capturing touch coordinates of the touch panel 34 from the coordinate detection unit 35 Are combined with the above-described software resources to realize various processing functions, and the display mode of the flat display panel 22 is controlled, for example, via the display control unit 33 according to the processing results.
[0021]
FIG. 4 is a diagram illustrating an example of a usage state of the electronic device 20. In this figure, (a) touches (or attempts to touch) the screen of the flat display panel 22 (the surface of the touch panel 34) with the pen 38 of the left hand HL while holding the right end of the electronic device 20 with the right hand HR. It shows how it is. In this case, the operating finger of the right hand HR is in contact with the rectangular pressing surface 281 of the first press sensing unit 28, and is single-ended with respect to the rectangular pressing surface 281 of the first press sensing unit 28 as desired. A tap operation, a double tap operation, a slide operation operation, or a mixed operation thereof can be performed.
[0022]
Further, (b) touches (or tries to touch) the screen of the flat display panel 22 (the surface of the touch panel 34) with the pen 38 of the right hand HR while holding the left end portion of the electronic device 20 with the left hand HL. It shows a state. In this case, the operating finger of the left hand HL is in contact with the rectangular pressing surface 291 of the second press sensing unit 29 and, if desired, the operating finger of the left hand HL can be single with respect to the rectangular pressing surface 291 of the second press sensing unit 29. A tap operation, a double tap operation, a slide operation operation, or a mixed operation thereof can be performed.
[0023]
FIG. 5 is a structural diagram illustrating an example of the first press sensing unit 28 and the second press sensing unit 29. When viewed as an electronic circuit, the first press sensing unit 28 is a circuit composed of normally-off type n switch elements SW1, SW2, SW3,..., SWn, as shown in FIG. expressed. Then, one switch segment of each switch element SW1 to SWn is individually connected to terminals Pv1, Pv2, Pv3,..., Pvn, and the other switch segment of all switch elements SW1 to SWn is shared. And connected to the terminal Pvcom.
[0024]
Similarly, the second press sensing unit 29 is represented by a circuit composed of n switch elements SW1, SW2, SW3,..., SWn, and one switch of each switch element SW1 to SWn. Each of the intercepts is individually connected to terminals Ph1, Ph2, Ph3,..., Phn, and the other switch intercept of all the switch elements SW1 to SWn is connected to a common terminal Phcom.
[0025]
Needless to say, such a circuit configuration can be realized with various structures. For example, a tact switch arrangement or a touch switch by electrostatic induction may be used, or a structure as shown in FIG. That is, the elastic bodies 28c (29c) are sandwiched at equal intervals between the rectangular pressing surfaces 281 (291) and 28b (29b) each made of an insulator, and a pair of elastic bodies 28c (29c) are sandwiched between them. When the contact point 28d (29d) is disposed, the thickness L of the elastic body 28c (29c) is set to such an extent that the contact point 28d (29d) does not come into contact with the steady state, and the pressing sensor 281 (291) is pushed down by the user The thickness L is reduced so that the contact point 28d (29d) comes into contact. The contacts 28d (29d) correspond to SW1, SW2, SW3,..., SWn, respectively, and the arrangement interval D is about the size of the user's thumb.
[0026]
According to this structure, when an arbitrary position of one insulator (the upper rectangular pressing surface 281 (291) in the figure) is pressed down by the user's thumb, one or a plurality of contacts 28d positioned at the pressed-down portion. (29d) is turned on. Therefore, for example, if a predetermined potential corresponding to logic 1 is given to the common terminal Pvcom (Phcom), the logic from the terminal Pi via the contact 28d (switch element SWi: i is 1 to n) in the above-described ON state. 1 can be taken out.
[0027]
Hereinafter, in order to simplify the description, the number n of the switch elements SWi is assumed to be five, and the signals extracted from the terminals Pv1 (Ph1) to Pv5 (Ph5) are represented by a 5-bit signal string. Furthermore, the signal extracted from the terminal Pv1 (Ph1) is the most significant bit, and the signal extracted from the terminal Pv5 (Ph5) is the least significant bit. That is, when all the switch elements SW1 to SW5 are in the OFF state, the all-logic 0 signal string (“00000”) is taken out from the terminals Pv1 (Ph1) to Pv5 (Ph5), and only the leftmost switch element SW1 is in the ON state. In this case, a 5-bit signal sequence (“10000”) in which only the most significant bit is logic 1 is taken out from the terminals Pv1 (Ph1) to Pv5 (Ph5).
[0028]
FIG. 6 is a conceptual diagram of a memory map of the ROM 32. The ROM 32 has a storage area 32a of an operating system (also referred to as a basic program) and a storage area 32b of an application program (also referred to as an application program), and further a specific program (a program for realizing processing specific to the present embodiment). Hereinafter, the storage area 32c of “enlargement / reduction program” is referred to for convenience.
[0029]
7 and 8 are flowcharts showing the main part of the “enlargement / reduction program”. In this flowchart, first, it is determined whether or not the screen is touched (step S11). The “screen” is a touch surface of the transparent touch panel 34 that covers the display screen of the flat display panel 22. That is, in this step S11, it is determined whether or not the touch panel 34 is touched with the pen 38. In this specification, a touch with the pen 38 is assumed, but the present invention is not limited to this. You may touch with "thing" other than the pen 38, or a fingertip. If the screen is not touched, the flowchart is terminated. If the screen is touched, it is next determined whether or not the touch position is on the image object (step S12). Here, the image object refers to an image such as a photograph pasted at an arbitrary position on an application screen such as word processing software, and the image object itself is an operation object (object).
[0030]
For example, in FIG. 10A, an image object 40 is pasted on an application screen 39 such as word processing software. The image object 40 constitutes an image-containing document together with character strings 39a and 39b in the application screen 39. Now, as shown in FIG. 10A, for example, when the upper left position Pa of the image object 40 is touched with the pen 38, the determination result of the above step S12 becomes YES, while the part other than the image object 40 is touched. If it has been touched or nowhere is touched, the determination result in step S12 is NO. If the determination result is NO, the flowchart is ended, and if YES, the process proceeds to the next step to determine whether or not a slide operation has been performed (step S13).
[0031]
As described above, the sliding operation refers to a pressing operation with a fingertip shift in the vertical direction performed on the rectangular pressing surface 281 of the first press sensing unit 28. Alternatively, it refers to a pressing operation that involves shifting the fingertip in the horizontal direction performed on the rectangular pressing surface 291 of the second pressing sensing unit 29.
[0032]
If the slide operation is not performed, the flowchart is ended. If the slide operation is performed, the process proceeds to the determination process (step S14 to step S17) of the slide direction (up, left, down, right). Accordingly, “enlargement processing” (step S18) and “reduction processing” (step S19) are executed. Specifically, in the illustrated flowchart, the “upward slide operation” performed on the rectangular pressing surface 281 of the first press sensing unit 28 or the rectangular pressing surface 291 of the second press sensing unit 29. When the “left slide operation” performed is determined, the “enlargement process” described later is executed, and the “downward slide operation” performed on the rectangular pressing surface 281 of the first press sensing unit 28 or When “rightward slide operation” performed on the rectangular pressing surface 291 of the second press sensing unit 29 is determined, a “reduction process” described later is executed. “Upward sliding operation” and “leftward sliding operation” correspond to “one direction sliding operation” described in the gist of the invention, and “downward sliding operation” and “rightward sliding operation” are inventions. This corresponds to the “sliding operation in two directions” described in the summary.
[0033]
In this way, “enlargement processing” is executed in response to “upward slide operation” or “leftward slide operation”, while “reduction processing” is executed in response to “downward slide operation” or “rightward slide operation”. The reason for executing "" is that it seems to match the user's intuitive operation image. That is, there is an intuitive relationship between the “enlargement” and “reduction” operations to be performed on the object (see the image object 40 in FIG. 10A) and the respective slide directions. This is because the idea of the present invention is not limited to the correspondence between the slide direction and the enlargement / reduction direction. In practice, you should test the reactions of many users and set an appropriate correspondence.
[0034]
<Enlargement processing>
FIG. 9 is a diagram illustrating a flowchart of the enlargement process. In this flowchart, first, the touch coordinates of the touch panel 34 are acquired, and the touch coordinates are set as enlarged origin coordinates (step S18a). The touch coordinates are, for example, the coordinates of the upper left position Pa of the image object 40 in FIG. Next, a slide operation amount is acquired, and an enlargement ratio is obtained from the slide operation amount (step S18b). The slide operation amount refers to, for example, an upward fingertip shift amount performed on the rectangular pressing surface 281 of the first press sensing unit 28 in the case of an upward sliding operation, or In the case of a leftward sliding operation, it means the amount of fingertip displacement in the leftward direction performed on the rectangular pressing surface 291 of the second pressure sensing unit 29. The larger the shift amount, the larger the enlargement ratio. The relationship between the shift amount and the enlargement ratio may be a linear proportional relationship, or may be a relationship in which the enlargement ratio increases nonlinearly as the shift amount increases.
[0035]
Once the enlargement rate is obtained, the enlargement amount (vertical / horizontal size) of the target image object 40 is calculated based on the enlargement rate (step S18c). For example, if the enlargement ratio is A, the original horizontal size of the image object 40 is X, and the original vertical size is Y, “X × A = X ′” and “Y × A = Y ′”. Ask. Here, X ′ is the horizontal size of the image object 40 after enlargement, and Y ′ is the vertical size of the image object 40 after enlargement. Finally, X ′ and Y ′ are applied, the image object 40 is redrawn (step S18d), and the flowchart ends.
[0036]
FIG. 10 is a diagram illustrating an example of the enlargement processing operation. In this figure, after touching an arbitrary position (upper left position Pa in the figure) of the image object 40 with the pen 38 and then sliding the rectangular pressing surface 281 of the first pressing sensing unit 28 with the thumb of the right hand HR, The horizontal size X and the vertical size Y of the image object 40 are enlarged according to the slide operation amount, and the image object 40 is redrawn with the horizontal size X ′ and the vertical size Y ′ after the enlargement. Reference numeral 40 ′ represents the redrawn image object 40. As described above, according to the present embodiment, after touching the desired image object with the pen 38, the right-hand HR thumb slides the rectangular pressing surface 281 of the first pressing sensor 28 upward. Alternatively, although not shown, the desired image object can be enlarged and displayed at a desired magnification by simply sliding the rectangular pressing surface 291 of the second pressing sensor 29 leftward with the thumb of the left hand HL. Can do. Therefore, unlike conventional ones, it is not necessary to perform a troublesome mouse operation, and thus it is possible to realize a suitable enlarged display control particularly applied to a handheld operation type electronic device.
[0037]
<Reduction processing>
FIG. 11 is a diagram illustrating a flowchart of the reduction process. In this flowchart, first, the touch coordinates of the touch panel 34 are acquired, and the touch coordinates are set as reduced origin coordinates (step S19a). The touch coordinates are, for example, the coordinates of the upper left position Pb of the image object 40 in FIG. Next, a slide operation amount is acquired, and a reduction rate is obtained from the slide operation amount (step S19b). The slide operation amount refers to, for example, a downward fingertip shift amount performed on the rectangular pressing surface 281 of the first press sensing unit 28 in the case of a downward sliding operation, or In the case of a rightward sliding operation, it refers to the amount of fingertip shift in the right direction performed on the rectangular pressing surface 291 of the second press sensing unit 29. The larger the shift amount, the greater the reduction ratio. The relationship between the shift amount and the reduction rate may be a linear proportional relationship, or may be a relationship in which the reduction rate increases nonlinearly as the shift amount increases.
[0038]
Once the reduction ratio is obtained, the reduction amount (vertical / horizontal size) of the target image object 40 is calculated based on the reduction ratio (step S19c). In this calculation, for example, assuming that the reduction ratio is B, the original horizontal size of the image object 40 is X, and the original vertical size is Y, “X × B = X ′” and “Y × B = Y ′”. Ask. Here, X ′ is the horizontal size of the image object 40 after reduction, and Y ′ is the vertical size of the image object 40 after reduction. Finally, X ′ and Y ′ are applied, the image object 40 is redrawn (step S19d), and the flowchart ends.
[0039]
FIG. 12 is a diagram illustrating an example of the reduction processing operation. In this figure, after touching an arbitrary position (upper left position Pb in the figure) of the image object 40 with the pen 38 and then sliding down the rectangular pressing surface 281 of the first pressing sensor 28 with the thumb of the right hand HR, The horizontal size X and the vertical size Y of the image object 40 are reduced according to the slide operation amount, and the image object 40 is redrawn with the reduced horizontal size X ′ and vertical size Y ′. Reference numeral 40 ′ represents the redrawn image object 40. As described above, according to the present embodiment, after touching a desired image object with the pen 38, the right-hand HR thumb can be used to slide the rectangular pressing surface 281 of the first pressing sensing unit 28 downward. Alternatively, although not shown, the desired image object can be reduced and displayed at a desired magnification by simply sliding the rectangular pressing surface 291 of the second pressing sensor 29 to the right with the thumb of the left hand HL. Can do. Therefore, unlike conventional ones, it is not necessary to perform a troublesome mouse operation, and thus it is possible to realize a reduced display control suitable for application to a hand-held operation type electronic device.
[0040]
In the above description, the upper left positions Pa and Pb of the enlargement / reduction target image object 40 are the origin position coordinates for enlargement / reduction, but the present invention is not limited to this. It may be anywhere on the image object 40.
FIG. 13 is a diagram showing an example of this, and is an example in which a substantially central position Pc of the image object 40 is used as a reference for enlargement / reduction (touch position by the pen 38). In this case, the enlargement / reduction processing of the image object 40 is executed with the center position Pc as the origin position coordinates. That is, by obtaining the vertical and horizontal enlargement ratios from the center position Pc according to the slide amount, and applying the enlargement ratios to redraw the image object 40, the enlarged image object 41 is obtained. Alternatively, a reduced image object 42 is obtained by obtaining vertical and horizontal reduction ratios from the center position Pc according to the slide amount, and redrawing the image object 40 by applying the reduction ratios.
[0041]
【The invention's effect】
According to the present invention, after touching the image object displayed on the display unit, the image object is enlarged / reduced and redrawn according to the slide direction and the slide amount by simply sliding the mechanical slide bar. Is done.
Accordingly, since a complicated mouse operation as in the conventional example is not required, in particular, in a hand-held electronic device, an electronic device capable of enlarging / reducing an image object displayed on the screen by a simple operation and its display control A method can be provided.
