[Embodiment 1]
Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. In each of the following embodiments, a smartphone will be described as an example of an electronic device in which display on a display surface is controlled by the display control device according to the present invention. It is assumed that the display on the display surface of the smartphone is controlled by mounting the display control device according to the present invention on the smartphone.

  In addition, as the electronic device on which the display control device according to the present invention can be mounted, in addition to a smartphone, a personal computer, a game machine, a tablet terminal, a home appliance such as a refrigerator, and the like are assumed. Further, the display control device according to the present invention does not necessarily need to be mounted on the electronic device as described above. For example, the display control device according to the present invention is mounted on an external information processing device, and information related to proximity / contact of the operating tool with respect to the display surface of the smartphone is transmitted and received between the information processing device and the smartphone. May be controlled.

<Functional configuration of smartphone>
First, a functional configuration of the smartphone 100 will be described with reference to FIG. FIG. 1 is a block diagram showing a main part of smartphone 100. The smartphone 100 (electronic device) is a multifunctional mobile phone having functions such as a personal computer and a PDA (Personal Digital Assistant). As illustrated in FIG. 1, the smartphone 100 includes a display unit 11, a storage unit 12, an operation unit 13, an application processing unit 14, and a control unit 15.

  The display unit 11 includes a touch panel (not shown), a circuit for performing display processing, and the like, and displays an image 50 (see FIG. 2 and the like), a cursor, and the like on the display surface 11a of the touch panel. The touch panel operates as a part of the display unit 11 and a part of the operation unit 13. The image 50 displayed on the display surface 11a includes a plurality of button regions (a plurality of regions) each associated with a different object (predetermined function). Specifically, the image 50 includes a button area A associated with the first object, a button area B associated with the second object, and a button area C associated with the third object. (See FIG. 2 etc.).

  Note that, in the present specification, an area in the image 50 to which an object is associated is expressed as a “button area”, but the display shape of the area to which the object is associated is represented by a button shape (for example, a square shape, (Round type) is not intended. That is, the display shape of the “button area” may be any shape.

  The display surface 11a of the touch panel is in a scroll mode in which the image 50 is normally displayed in a scrollable manner. On the other hand, when the operation unit 13 detects the proximity or contact of the user's finger 20 (the operation tool: see FIG. 2 and the like) to the display surface 11a, the display surface 11a is appropriately moved to the image 50 by the scroll control unit 16 described later. The state transits to the non-scroll mode in which the scrolling is stopped. The details of the transition from the scroll mode to the non-scroll mode and the release of the non-scroll mode will be described later.

  In the following description, proximity is expressed as “hover”, and contact is expressed as “touch”. In the following embodiments, a touch panel in which a part of the display unit 11 and a part of the operation unit 13 are integrated is described as an example, but the display unit 11 and the operation unit 13 , May be individual devices.

  The storage unit 12 is configured by, for example, a ROM (Read Only Memory) or a RAM (Random Access Memory), and stores data necessary for the operation of each unit included in the smartphone 100. The storage unit 12 also receives information from the scroll control unit 16 described later that the display of the display surface 11a has transitioned from the scroll mode to the non-scroll mode, and that the non-scroll mode has been released and the scroll mode has been returned. Is stored. The storage unit 12 may be provided in the control unit 15 or may be provided outside the smartphone 100.

  The operation unit 13 has a touch panel, a circuit for performing operation input processing, and the like, and detects an input operation from a user, and the user's finger 20 (hereinafter, abbreviated as “finger 20”) is placed in an arbitrary area in the image 50. Hover and touch detection are performed. The operation unit 13 also calculates the position of the cursor displayed on the display surface 11a and the like. The application processing unit 14 performs an application-specific process.

  The control unit 15 is, for example, a CPU, and controls the operation of each unit included in the smartphone 100 by executing a program stored in the storage unit 12. Further, the control unit 15 includes the display control device 1. The display control device 1 appropriately controls the display on the display surface 11a according to the hover or touch of the finger 20 on the display surface 11a of the touch panel. As shown in FIG. 1, the display control device 1 includes a scroll control unit 16 and a selection state switching unit 17.

  The scroll control unit 16 detects that the finger 20 has hovered or touched the first button region (first region) of the button region A, the button region B, and the button region C (the plurality of regions) by the operation unit 13. From this point, scrolling of the image 50 is stopped. That is, the scroll control unit 16 causes the display on the display surface 11a to transition from the scroll mode to the non-scroll mode from the time when the hover or touch of the finger 20 on the first button area is detected. Here, the first button area refers to the button area that the user first hovered or touched in the state where the display of the display surface 11a is in the scroll mode (normal time) among the button areas A to C.

  When the scroll of the image 50 is stopped, the scroll control unit 16 causes the operation unit 13 to move the finger 20 to the second button area (second area) of the button area A, the button area B, and the button area C. When the hover or touch of the finger 20 on the image 50 itself is not detected after the hover or the touch is detected, the stop of the scroll of the image 50 is released.

  That is, after the transition to the non-scroll mode, the scroll control unit 16 continues the non-scroll mode while the hover or touch of the finger 20 on the image 50 itself is continuously detected. Further, when the user releases the finger from the image 50 itself after hovering or touching the finger 20 to the second button area while the non-scroll mode is continued, the scroll control unit 16 cancels the non-scroll mode (that is, the image 50 Then, the display of the display surface 11a is returned to the scroll mode. Here, the second button area is a button area different from the first button area among the button areas A, B, and C in which hover or touch of the finger 20 is detected while the non-scroll mode is continued. Point to.

  In the present embodiment, the scroll control unit 16 stops the scroll of the image 50 from the time when the hover or the touch of the finger 20 to the first button area is detected, but is not limited to this control mode. For example, as described in detail in the second embodiment, the scroll of the image 50 may be stopped when a predetermined time has elapsed after the hover or touch of the finger 20 on the first button area is detected. In other words, when the hover or the touch of the finger 20 to the first button area is detected, the scroll control unit 16 determines whether the hover or the touch of the finger 20 to the image 50 itself is continuously detected. , As long as scrolling of the image 50 is stopped.

  While the scroll control unit 16 stops scrolling the image 50, that is, while the non-scroll mode continues, the selection state switching unit 17 uses the operation unit 13 to switch a specific button area from the button area A to the button area C. When it is detected that the finger 20 is hovered or touched, the display of the specific button area is switched to a highlight display (selection state).

  When the hover or touch of the finger 20 is no longer detected in the specific button area, the selection state switching unit 17 cancels the highlight display. In this case, when the non-scroll mode is continued and hover or touch is detected in a button area different from the specific button area, the selection state switching unit 17 highlights the display of the different button area. Switch to

  In the present embodiment, the selection state switching unit 17 switches the display of the specific button area in which the hover or touch of the finger 20 is detected during the non-scroll mode to the highlight display. It does not need to be displayed. For example, when the hover or touch of the finger 20 is detected in the specific button area while the non-scroll mode is continued, the specific button area may blink. In other words, when the hover or touch of the finger 20 to the specific button area is detected while the non-scroll mode is continued, the selection state switching unit 17 switches the display of the specific button area to the selection state. Anything should do. The selected state indicates that the specific button area is displayed on the display surface 11a with emphasis on other button areas from the button area A to the button area C.

  Further, the selection state switching unit 17 is a member for allowing the user to easily grasp which button area the finger 20 is hovering and touching, and therefore, is always provided in the display control device 1. It is not necessary. In other words, the selection state switching unit 17 is not an essential component of the display control device according to the present invention.

<Transition to non-scroll mode and cancellation of non-scroll mode>
Next, transition to the non-scroll mode and release of the non-scroll mode by the display control device 1 will be described with reference to FIGS. FIG. 2 is a schematic diagram showing a display state of the display surface 11a in the scroll mode. FIG. 3 is a schematic diagram showing a display state of the display surface 11a in the non-scroll mode.

  As shown in FIG. 2, the display on the display surface 11a of the touch panel is normally in the scroll mode. When the operation unit 13 detects hover or touch of the finger 20 in the area other than the button area A to the button area C in the image 50 displayed on the display surface 11a during the scroll mode, the control unit 15 , And instructs the application processing unit 14 to scroll the image 50. Upon receiving the instruction from the control unit 15, the application processing unit 14 scrolls the image 50 according to the direction in which the finger 20 slides on the display surface 11a. In FIG. 2, since the finger 20 slides upward on the display surface 11a toward the paper surface, the entire image 50 is scrolled upward toward the paper surface.

  Further, even when the hover or the touch of the finger 20 is detected in any of the button areas A to C by the operation unit 13 during the scroll mode, if the finger 20 is released from the image 50 itself after the detection. , The scroll mode continues. In this case, the control unit 15 receives from the operation unit 13 the coordinate value of the button area where the hover or touch of the finger 20 is detected (details will be described later). Further, the application processing unit 14 executes the function of the object associated with the button area where the hover or the touch of the finger 20 is detected according to the instruction of the control unit 15.

  On the other hand, during the continuation of the scroll mode, when the hover or touch of the finger 20 is detected in any of the button areas A to C by the operation unit 13, the display control device 1 displays the display surface 11a in FIG. A transition is made to the non-scroll mode as shown in FIG. In FIG. 3, the transition to the non-scroll mode is performed by the user hovering or touching the button area C with the finger 20 during the continuation of the scroll mode. In this case, the button area C becomes the first button area. Further, the display control device 1 switches the display of the button area C to the highlight display.

  After the display on the display surface 11a has shifted to the non-scroll mode, the display control device 1 continues the non-scroll mode while the finger 20 slides on the display surface 11a. When the operation unit 13 detects that the finger 20 has hovered or touched a button area different from the first button area, the display control device 1 highlights the different button area. In FIG. 3, the display of the button area B is switched to the highlight display by the user sliding the finger 20 from the button area C to the button area B.

  Then, for example, when the user releases the finger 20 from the button area B (not shown), that is, when the hover or touch of the finger 20 on the image 50 itself is not detected, the display control device 1 releases the non-scroll mode. Then, the display on the display surface 11a is returned to the scroll mode. In this case, the control unit 15 receives a coordinate value of a button area B described later from the operation unit 13. Further, the application processing unit 14 executes the function of the object associated with the button area B according to an instruction from the control unit 15.

  Here, which region in the image 50 is hovered or touched by the finger 20 is determined by the operation unit 13 calculating coordinate values (X coordinate, Y coordinate) corresponding to the region hovered or touched by the finger 20. I do. Specifically, the display surface 11a of the touch panel defines a Y-axis along the longitudinal direction of the display surface 11a and an X-axis orthogonal to the Y-axis (not shown). For example, the Y-axis is positive downward on the paper and the X-axis is positive on the right of the paper. The operation unit 13 calculates a coordinate value corresponding to an area touched or hovered by the finger 20 using these two coordinate axes.

  Further, the storage unit 12 stores in advance coordinate values (reference coordinate values) representing the outer edges of the button areas A to C, respectively. The display control device 1 and the control unit 15 call each reference coordinate value from the storage unit 12 and determine whether the coordinate value received from the operation unit 13 is included in any of the button areas A to C. . The display control device 1 and the control unit 15 perform the above-described determination to determine which button area the finger 20 is hovering or touching, and to hover or touch the area other than the button area C from the finger area A to the finger 20. It is determined whether the user is touching.

  In the present embodiment, the number of button regions included in the image 50 is three from the button region A to the button region C. However, the number of button regions may be any number other than a single button region. . Further, the contents of the first object to the third object associated with each of the button areas A to C may have any contents.

<Display control method by display control device>
Next, a display control method performed by the display control device 1 will be described with reference to FIG. FIG. 4 is a flowchart illustrating a display control method performed by the display control device 1.

  Normally (when the display on the display surface 11a is in the scroll mode), the operation unit 13 detects a hover or a touch of the finger 20 to any area in the image 50, that is, the operation unit 13 At the point in time when the coordinate values of the touched area are calculated, the scroll control unit 16 sets the coordinate values calculated by the operation unit 13 in any of the button areas A to C as shown in FIG. It is determined whether or not it is included (Step 10, hereinafter abbreviated as "S10": non-scroll mode transition determination step).

  When YES is determined in S10 (hereinafter abbreviated as “Y”), the button area determined to include the coordinate value in the area becomes the first button area, and the selection state switching unit 17 The display of the area is switched to the highlight display (S11: first highlight display switching step). At the same time, the scroll control unit 16 transitions the display on the display surface 11a of the touch panel to the non-scroll mode (S12: non-scroll mode transition step (scroll stop step)). On the other hand, if the determination in S10 is NO (hereinafter abbreviated as “N”), the application processing unit 14 executes a function corresponding to the area in the image 50 in which the coordinate values have been calculated according to an instruction from the control unit 15. (S19: normal function execution step).

  Next, the scroll control unit 16 determines whether the finger 20 is sliding on the display surface 11a, that is, whether the hover or touch of the finger 20 on the image 50 itself is continuously detected by the operation unit 13. (S13: slide detection step). When Y is determined in S13, the operation unit 13 detects a hover or a touch of the finger 20 in any one of the button regions A to C, that is, the operation unit 13 hovers or touches the button 20 with the finger 20. After calculating the coordinate value of the area, the scroll control unit 16 determines whether or not the coordinate value calculated by the operation unit 13 is included in a button area different from the first button area (S17: second button). Area detection step).

  If Y is determined in S17, the different button area becomes the second button area, and the selection state switching unit 17 switches the display of the second button area to highlight display (S18: second highlight display switching step). Then, the process returns to S13. On the other hand, if it is determined to be N in S17, the process returns to S13.

  Next, when it is determined as N in S13, the scroll control unit 16 determines whether the finger 20 is released from the display surface 11a, that is, after the hover or touch of the finger 20 to the first button area is detected, It is determined whether the hover or touch of the finger 20 on the image 50 itself is no longer detected (S14: finger release determination step). If the process shifts from the process of S17 to the process of S13, after the hover or touch of the finger 20 to the first button area is detected, the finger 20 slides, and then the hover of the finger 20 to the image 50 itself or It is determined whether or not the touch is no longer detected. If the process has shifted from S18 to S13, it is determined whether the hover or touch of the finger 20 on the image 50 itself is no longer detected after the hover or touch of the finger 20 on the second button area is detected. judge.

  If Y is determined in S14, the application processing unit 14 executes the function of the object corresponding to the first button area according to the instruction of the control unit 15 (S15: function execution step). If the process has shifted from the process of S17 to the process of S13, a function corresponding to the area in the image 50 that has been hovered or touched immediately before release is executed. If the process has shifted from the process of S18 to the process of S13, the function of the object corresponding to the second button area is executed. On the other hand, if it is determined to be N in S14, the process returns to S13.

  At the same time as the processing of S15, the scroll control unit 16 releases the non-scroll mode for the display on the display surface 11a and returns to the scroll mode (S16: non-scroll mode release step (scroll stop release step)).

It is preferable to further include a selection state switching unit (17) for switching to a selection state displayed on the display surface.

  According to the above configuration, when the user makes the operating tool hover-touch a specific area while the scrolling of the image is stopped, the specific area is displayed more emphasized than other areas. Therefore, since the user can easily grasp which area the user is hover touching, the user can hover-touch the operating tool more reliably in the area intended by the user.

  The display control device (3) according to a fifth aspect of the present invention is the display control device according to any one of the first to fourth aspects, wherein, when the contact of the operating body with the first region is detected, the operating body is in the first position. The apparatus further includes a first pressing force determination unit (18) that determines whether a force pressing the region is equal to or less than a first threshold value, and the scroll control unit is configured to perform the pressing by the first pressing force determination unit. It is preferable that the scrolling of the image is stopped when it is determined that the force to perform is equal to or less than the first threshold.

  When the pressing force of the operating tool applied to the region is larger than a certain value, it can be assumed that there is a high possibility that the user has intentionally selected the predetermined function associated with the region. On the other hand, when the pressing force is equal to or less than the predetermined value, it can be assumed that there is a high possibility that the user has unintentionally touched the area.

  In this regard, according to the above configuration, scrolling of the image is stopped when the first pressing force determination unit determines that the force with which the operating tool presses the first region is equal to or less than the first threshold. Therefore, when the user unintentionally touches the first area, the scrolling of the image does not stop, and it is possible to avoid unnecessary scrolling of the image.
