Description

The present invention relates to a touch panel device capable of scrolling an image.

In general, the touch panel device can execute scroll processing when displaying a part of a specific image such as a menu image including an icon on a display panel. The touch panel device executes the scroll process when it detects a scroll operation such as a swipe operation along a predetermined direction.

Normally, when the touch panel device detects a touch operation other than the scroll operation on the display panel during the execution of the scroll process, the touch panel device stops the scroll process.

Further, when the touch panel device detects an icon designation operation of touching the area of the icon on the display panel while the scrolling process is stopped, the touch panel device executes a process associated with the icon in advance.

Further, when the touch panel device detects a touch operation on the display panel during the execution of the scroll process, the process corresponding to the touch operation is stopped until the scroll process is stopped and the touch operation is released. Is not performed (see, for example, Patent Document 1).

By the way, it is troublesome for the user to perform both the operation of stopping the scrolling process and the operation of designating the icon. When the scrolling process is being performed, it is desired that the process corresponding to the icon is executed by one touch operation for designating the icon.

On the other hand, when the scrolling process is being performed, it is necessary to prevent the touch operation performed with the intention of stopping or continuing the scrolling process from being erroneously detected as the icon designation operation.

An object of the present invention is that when an image including an icon is scrolled on a display panel, the icon can be specified by a single touch operation, and the touch operation performed with the intention of stopping or continuing the scrolling process is described. An object of the present invention is to provide a touch panel device that can prevent erroneous detection as an operation of designating an icon.

The touch panel device according to one aspect of the present invention includes a display panel, a position detection device, an operation determination device, and a display control device. The display panel displays an image. The position detecting device detects a touch position on the display panel. The operation determination device determines the type of panel operation according to the detection result of the touch position. The display control device displays a part of a specific image including an icon on the display panel, and changes the display form of the image on the display panel according to the determination result of the panel operation. When the position detection device detects the touch position while the display control device scrolls the specific image on the display panel, the display control device determines the scroll state of the specific image in advance. Judges whether or not the icon can be specified. Further, the operation determination device distinguishes and determines whether the panel operation is an icon designation operation or another operation which is a predetermined one operation for designating the icon. When it is determined that the scroll state of the specific image is the icon-designable state and the panel operation is the icon-designated operation, the display control device is associated with the icon in advance. The icon-corresponding process is executed, and if not, the display control device continues or stops the scroll display of the specific image on the display panel without executing the icon-corresponding process.

According to the present invention, when an image including an icon is scrolled on the display panel, the icon can be specified by a single touch operation, and the touch operation performed with the intention of stopping or continuing the scrolling process is described.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that the following embodiment is an example embodying the present invention and does not have a character that limits the technical scope of the present invention.

[Structure of touch panel device 10]
The touch panel device 10 according to the embodiment is a device in which a smartphone, a tablet PC (Personal Computer), or an image forming device is incorporated into an electronic device.

As shown in FIG. 1, the touch panel device 10 includes a touch panel unit 100, a control device 4, a secondary storage device 5, a communication device 6, and the like.

The touch panel unit 100 includes a display panel 1, a position detection device 2, and a panel drive circuit 3. Further, the control device 4 includes a CPU (Central Processing Unit) 41 and a main storage device 42 such as a RAM (Random Access Memory).

The display panel 1 is a panel-shaped display device such as a liquid crystal panel. The display panel 1 displays an image including various information according to the control by the CPU 41.

The position detection device 2 detects the touch position with respect to the display panel 1. The touch position is a position on the display panel 1 where a user's finger or an operating member such as a stylus pen comes into contact. For example, it is conceivable that the position detection device 2 is a capacitance type, resistance type or optical type touch panel. The panel drive circuit 3 is a circuit that controls the display state of the display panel 1 according to a control signal from the CPU 41.

The communication device 6 is a communication interface device that communicates with another device. For example, the communication device 6 transfers data received from another device to the CPU 41. Further, the communication device 6 transmits the data transferred from the CPU 41 to the other device in accordance with the transmission command from the CPU 41.

The CPU 41 executes various calculations, data processing, control of the touch panel unit 100, and the like. The main storage device 42 is a RAM (Random Access Memory) and a storage device for temporarily storing data used for various programs and calculations executed by the CPU 41.

The secondary storage device 5 is a computer-readable non-volatile storage device. For example, a flash memory or a hard disk drive is adopted as the secondary storage device 5. The secondary storage device 5 stores in advance a program executed by the CPU 41, data referenced by the CPU 41, and the like.

For example, the CPU 41 functions as the display control device 4a by executing the display control program 5a stored in the secondary storage device 5 in advance. Further, the CPU 41 functions as the operation determination device 4b by executing the operation determination program 5b stored in advance in the secondary storage device 5.

The display control device 4a controls the display panel 1 through the panel drive circuit 3. For example, the display control device 4a causes the display panel 1 to display a part of the specific image g0 including the icon g1 (see FIG. 3).

In the following description, one of the vertical direction and the width direction of the display panel 1 is referred to as a main direction D1, and the other is referred to as a sub direction D2. In the example shown in FIG. 3, the vertical direction is the main direction D1 and the width direction is the sub direction D2.

The specific image g0 shown in FIG. 3 is an image in which the length of the main direction D1 is longer than the length of the main direction D1 of the display panel 1. On the other hand, the length of the sub-direction D2 of the specific image g0 is equal to or less than the length of the sub-direction D2 of the display panel 1.

The operation determination device 4b determines the type of panel operation according to the detection result of the touch position by the position detection device 2. For example, the operation determination device 4b distinguishes the scroll operation, the icon designation operation, and other operations for the display panel 1.

As shown in FIG. 4, it is conceivable that the scroll operation is a swipe operation along the main direction D1. In the example shown in FIGS. 4 and 5, the display panel 1 is operated by the user's finger F0.

It is also conceivable that the operation determination device 4b is realized by a processor such as a DSP (Digital Signal Processor) or MPU (Micro Processing Unit) or a circuit such as an ASIC (Application Specific Integrated Circuit).

The display control device 4a changes the display form of the image on the display panel 1 according to the determination result of the panel operation by the operation determination device 4b.

In the example shown in FIG. 3, the display control device 4a causes the display panel 1 to display a part of the area of the main direction D1 in the specific image g0. In this state, when the touch position is detected by the position detection device 2 and the operation determination device 4b determines that the touch operation is the scroll operation, the display control device 4a displays the specific image on the display panel 1. Scroll display of g0 along the main direction D1.

In FIGS. 4 to 7, the scroll direction D0 is indicated by an arrow. In the following description, the process of scrolling the specific image g0 on the display panel 1 is referred to as a scroll process.

In the present embodiment, the icon designation operation includes a first icon designation operation and a second icon designation operation. The first icon designation operation is an operation of designating the icon g1 when the specific image g0 is displayed as a still image on the display panel 1 as shown in FIG.

As shown in FIG. 3, when the specific image g0 is displayed as a still image on the display panel 1, the operation determination device 4b performs a tap operation of touching the area where the icon g1 is displayed on the display panel 1. It is determined that this is the first icon designation operation.

On the other hand, the second icon designation operation is an operation of designating the icon g1 when the specific image g0 is scrolled and displayed on the display panel 1. The second icon designation operation will be described later.

When the operation determination device 4b determines that the touch operation is the first icon designation operation, the display control device 4a executes a process associated with the icon in advance. In the following description, the process associated with the icon g1 that is the target of the icon designation operation is referred to as an icon correspondence process.

For example, it is conceivable that the icon-corresponding process is a process of displaying a specific image g0 different from the previous one on the display panel 1 or a process of displaying a pop-up image on the display panel 1 overlaid on the specific image g0. Further, it is conceivable that the CPU 41 executes arithmetic processing or communication processing through the communication device 6 in addition to changing the display content of the display panel 1.

By the way, it is troublesome for the user to perform both the operation of stopping the scrolling process and the operation of designating the first icon. While the scrolling process is being performed, it is desired that the icon-corresponding process is executed by one touch operation for designating the icon g1.

On the other hand, when the scrolling process is being performed, it is necessary to prevent the touch operation performed with the intention of stopping or continuing the scrolling process from being erroneously detected as the icon designation operation.

In the touch panel device 10, the display control device 4a and the operation determination device 4b execute the scrolling control described later when the scrolling process is being performed (see FIG. 2).

By performing the scrolling control, the icon g1 can be specified by one touch operation when the specific image g0 including the icon g1 is scrolled on the display panel 1. Further, it is possible to prevent the touch operation performed with the intention of stopping or continuing the scrolling process from being erroneously detected as the icon designation operation.

[Control during scrolling]
Hereinafter, an example of the scrolling control procedure will be described with reference to the flowchart shown in FIG.

The display control device 4a and the operation determination device 4b start the scrolling control when the scrolling process is started. In the following description, S1, S2, ... Represent an identification code for a plurality of steps in the scrolling control.

<Step S1>
In the scrolling control, first, the operation determination device 4b monitors whether or not the touch position is detected by the position detection device 2. When the position detecting device 2 detects the touch position while the scrolling process is being performed, the operation determination device 4b shifts the process to step S2.

<Process S2>
In step S2, the display control device 4a determines whether or not the scroll state of the specific image g0 is a predetermined icon-designable state. For example, the icon-designable state is a low-speed scrolling state in which the scrolling speed of the specific image g0 is lower than a predetermined threshold speed.

When the display control device 4a determines that the scroll state of the specific image g0 is the icon specifiable state, the process shifts to the process S3, and if not, the process shifts to the step S6.

<Process S3>
In step S3, the operation determination device 4b distinguishes and determines whether the panel operation is the second icon designation operation or the other operation. The second icon designation operation is a predetermined operation once.

In the present embodiment, the first icon designation operation and the second icon designation operation are different types of touch operations.

For example, as shown in FIG. 5, it is conceivable that the second icon designation operation is a swipe operation of rubbing the area where the icon g1 is displayed on the display panel 1 along the intersection direction Dx0.

The intersection direction Dx0 is a direction in which the specific image g0 intersects the scroll direction D0 within a predetermined angle range. The intersection direction Dx0 is a direction in a predetermined acute angle range with reference to the subdirection D2 orthogonal to the scroll direction D0.

When the operation determination device 4b determines that the panel operation is the second icon designation operation, the process shifts to the process S4, and if not, the process shifts to the step S6.

<Process S4>
In step S4, the display control device 4a stops scrolling of the specific image g0, and subsequently shifts the process to step S5.

<Process S5>
In step S5, the display control device 4a terminates the scrolling control after executing the icon-corresponding process.

<Step S6>
In step S6, the operation determination device 4b determines whether or not the panel operation is the scroll operation. When the operation determination device 4b determines that the panel operation is the scroll operation, the process shifts to the step S7, and if not, the process shifts to the step S8.

The process of step S6 is executed when it is determined that the scroll state of the specific image g0 is not the icon-designable state, or when it is determined that the panel operation is not the second icon-designated operation. To.

<Step S7>
In step S7, the display control device 4a continues the scrolling process. However, the display control device 4a adjusts the scroll speed of the specific image g0 according to the speed of the scroll operation.

Further, when the direction of the scroll operation is different from the scroll direction D0 at that time, the display control device 4a changes the scroll direction of the specific image g0.

After executing the process of step S7, the display control device 4a shifts the process to step S1. As a result, the process from step S1 is repeated.

<Step S8>
In step S8, the display control device 4a stops scrolling of the specific image g0 and then ends the scrolling control.

The process of step S8 is executed in the following first case or second case. In the first case, it is determined that the scroll state of the specific image g0 is not the icon specifiable state, and the panel operation is not the scroll operation. In the second case, it is determined that the scroll state of the specific image g0 is the icon-designable state, and that the panel operation is neither the second icon designation operation nor the scroll operation. Is.

As shown above, when the position detection device 2 detects the touch position while the display control device 4a scrolls the specific image g0 on the display panel 1, the display control device 4a causes the specific image g0. It is determined whether or not the scroll state of is in the icon specifiable state (S2).

Further, the operation determination device 4b distinguishes and determines whether the panel operation is the second icon designation operation or the other operation (S3).

Then, when it is determined that the scroll state of the specific image g0 is the icon-designable state and the panel operation is determined to be the icon-designated operation, the display control device 4a corresponds to the icon g1 in advance. The attached icon corresponding process is executed (S5). In other cases, the display control device 4a continues or stops the scroll display of the specific image g0 on the display panel 1 without executing the icon-corresponding process (S7, S8).

When it is determined in step S2 that the scrolling state of the specific image g0 is the low-speed scrolling state, the user can easily grasp and touch the position of the icon g1 during scrolling. In this case, the display control device 4a allows the execution of the icon corresponding process in response to the second icon designation operation (steps S2 to S5).

On the other hand, when the scroll state of the specific image g0 is not the low-speed scroll state, it is difficult for the user to accurately grasp the position of the icon g1 during scrolling. In this case, the display control device 4a does not allow the execution of the icon-corresponding process regardless of the type of the touch operation (steps S6, S7 or steps S6, S8). As a result, it is possible to prevent the touch operation performed with the intention of stopping or continuing the scrolling process from being erroneously detected as the second icon designation operation.

In the procedure shown in FIG. 2, it is conceivable that the process of step S3 is executed before the process of step S2.

Further, in the present embodiment, the second icon designation operation is a swipe operation of rubbing the area where the icon g1 is displayed on the display panel 1 along the intersection direction Dx0. In this case, the icon-corresponding process can be executed promptly.

[First application example]
As shown in FIGS. 6 and 7, it is conceivable that the specific image g0 includes a plurality of page images g00 in which the length of the predetermined main direction D1 is longer than the length of the main direction D1 of the display panel 1. ..

In this application example, when the display control device 4a scrolls the specific image g0 along the main direction D1 on the display panel 1, the display panel 1 scrolls and displays each of the plurality of page images g00 along the main direction D1. Let me.

Further, when the display control device 4a causes the display panel 1 to scroll and display the specific image g0 along the main direction D1, the display panel switches the two adjacent page images g00 at the page break g2 of the plurality of page images g00. Display at 1.

That is, the display control device 4a displays the display state of the display panel 1 from the state of FIG. 6 which displays one of the two adjacent page images g00 at the page break g2 of the plurality of page images g00, and displays the other. Switch to the state.

FIG. 6 shows the display panel 1 at the time when the upstream end g3 of the scroll direction D0 in the certain page image g00 reaches the upstream end 1a of the scroll direction D0 in the display panel 1 in the scroll processing.

On the other hand, FIG. 7 shows the display panel 1 on which the next page image g00 is displayed with the downstream end g4 of the scroll direction D0 in the next page image g00 along the downstream end 1b of the scroll direction D0 in the display panel 1. Shown.

When the display state of a certain page image g00 on the display panel 1 becomes the state shown in FIG. 6, the display control device 4a switches the display state of the display panel 1 to the display state shown in FIG. 7.

In the following description, a short period based on the time when the display of two adjacent page images g00 is switched is referred to as a page switching period.

During the page switching period, the user cannot predict the change in the display state of the display panel 1. Therefore, it is highly possible that the touch operation during the page switching period is an operation contrary to the intention of the user.

Therefore, it is conceivable that the display control device 4a determines in the step S2 of FIG. 2 a state in which both the following first condition and the second condition are satisfied as the icon-designable state.

The first condition is that the scroll speed of the specific image g0 is lower than the threshold speed in the low-speed scroll state. The second condition is a condition that the state is a state at a time other than a predetermined period based on the time when the display of the two page images g00 is switched. The second condition means excluding the page switching period.

If this application example is adopted, it is possible to prevent the touch operation during the page switching period from being erroneously detected as the second icon designation operation.

[Second application example]
In the scrolling control, it is conceivable that the process of step S4 of FIG. 2 is omitted. When the second icon designation operation is a swipe operation along the intersection direction Dx0, the icon correspondence process is promptly executed. Therefore, even if the process of step S4 is omitted, no particular problem occurs.

[Third application example]
It is conceivable that the icon designation operation is a long press operation of continuously touching the area on the display panel 1 where the icon g1 is displayed for a predetermined time or longer.

In this application example, it is desirable that the process of step S4 of FIG. 2 is not omitted. That is, when it is determined that the scroll state of the specific image g0 is the icon-designable state and the panel operation is the second icon-designated operation, the display control device 4a is set to step S4. The process of S5 is executed.
