Abstract

PROBLEM TO BE SOLVED: To enable improvement of the operability of a touch panel depending on a user's operation situation.SOLUTION: A camera function selection screen is displayed on a display mounted with a touch panel, and when one button is touched in a state where a plurality of objects (buttons) for instructing processing are displayed, a reaction region of a button whose function is the same before and after the touch among the displayed buttons except it is made smaller, and a reaction region of a button whose function is switched after the touch is made larger.

Description

  The present invention particularly relates to a display device equipped with a touch panel, a control method for the display device, and a program.

  In recent years, many products using touch panels have been developed as user interfaces for digital devices such as mobile phones and digital cameras. Since these products can be operated by directly touching the screen displayed on the LCD by overlaying a touch panel on a display device such as an LCD, an intuitive and easy-to-understand operation can be performed.

  However, unlike conventional physical buttons, button operations using a touch panel are flat with no physical boundaries. The buttons cannot be operated. In addition, when trying to touch the screen, a part of the screen is hidden by a finger, and the user may touch a place off the button even though he intends to press the button.

  Therefore, various techniques have been proposed to improve user operability. For example, Patent Literature 1 discloses a technique for determining a moving direction of a pointer from an operation of a pointing device, and changing and displaying an enlarged display layout of a window in the determined direction. Patent Document 2 discloses a technique for enlarging a reaction area of an object that can be touched on a display screen of a touch panel with respect to a user's line-of-sight direction.

JP 2007-179095 A JP-A-8-95708

  However, in the technique described in Patent Document 1, when a target window is enlarged when an object is operated with a pointing device, other displays displayed in the space may be hidden. . For this reason, it cannot be applied when there is an object that needs to be displayed.

  Moreover, the technique described in Patent Document 2 is effective when the positional relationship between the user's line of sight and the display device is always a constant relationship in principle, as in a navigation device mounted on a vehicle. However, in an information device such as a mobile phone or a digital camera, the positional relationship between the line of sight and the display device changes depending on how the user holds it. For this reason, it cannot respond when the line-of-sight direction changes.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to improve the operability of a touch panel according to an operation situation by a user.

  The display device of the present invention includes a display control unit that displays a plurality of objects for instructing processing on a display unit, a detection unit that detects an instruction for the object via a touch panel integrated with the display unit, An instruction for the object by the detecting means and a setting means for setting a reaction area to be detected, and the setting means detects an object for which the instruction is detected when an instruction for one object is detected by the detecting means. Accordingly, the reaction area for detecting an instruction to another object displayed on the display unit is changed.

  According to the present invention, the reaction area is changed by the operation of the object, and the operability of the touch panel can be improved according to the operation state by the user.

And. The imaging unit 107 also includes a microphone that inputs sound and converts it into a sound signal.

  The signal processing unit 109 adjusts an image such as white balance based on the control of the CPU 101 with respect to the video signal converted by the imaging unit 107, or adjusts the exposure by changing the shutter speed or aperture of the imaging unit 107. Or MPEG2 or H.264 The video signal is compressed by an encoding format such as H.264 and recorded on the internal recording medium 102 via the memory 103 or recorded on the external recording medium 108 by the external media input / output unit 106. The signal processing unit 109 also adjusts the volume of the audio signal, and compresses the audio signal in a predetermined encoding format. An audio signal is recorded together with the video signal.

FIG. 2 is a schematic diagram showing an external configuration example of the digital video camera 100 shown in FIG.
In FIG. 2A, the power switch 201, zoom bar 202, trigger button 203, touch panel mounted on the display 204, and mode switching button 205 are members that constitute the input unit 105. A power switch 201 is a main power switch of the digital video camera 100 of the present embodiment, and is a button for turning on / off the main power. The zoom bar 202 is a bar for continuously changing the angle of view by operating the zoom lens of the camera unit 207 shown in FIG.

  The trigger button 203 is a button for instructing start or stop of shooting. When the trigger button 203 is pressed during non-shooting, shooting starts. When the trigger button 203 is pressed during shooting, shooting stops. A mode switching button 205 is a button for switching between the camera shooting mode and the playback mode, and switches to the playback mode when the digital video camera 100 is in the camera shooting mode, and switches to the camera shooting mode when it is in the playback mode.

  The display 204 is configured by attaching a touch panel as the input unit 105 on an LCD. Further, the touch panel uses a transmissible panel that does not visually impede the image displayed on the LCD of the display 110. An external recording medium 108 such as an SD card is inserted into the external media insertion unit 206, and information such as images and sounds is recorded on the external recording medium 108 by the external media input / output unit 106.

  In FIG. 2B, the camera unit 207 and the microphone unit 208 are members constituting the imaging unit 107, respectively. The camera unit 207 includes a zoom lens, a focus lens, a diaphragm, a CMOS sensor, and the like, forms an optical image, and converts the optical image formed by the CMOS sensor into an electrical signal. Further, the microphone unit 208 inputs voice and converts it into a voice signal.

Hereinafter, in the present embodiment, an example in which the reaction area is enlarged or reduced when the function assigned on the touch panel of the digital video camera 100 is changed by the operation of the button will be described.
3 and 4 are flowcharts illustrating an example of a processing procedure when a touch panel is operated on a screen for selecting setting of a camera function (hereinafter, camera function selection screen). Each process shown in FIGS. 3 and 4 is performed under the control of the CPU 101.

  First, when the user operates the digital video camera 100 and receives an instruction to display a camera function selection screen, the process is started. In step S301, the display control unit 104 causes the display 110 to display a camera function selection screen on which a MENU button, a SHIFT button, an AF button, an AE button, a WB button, and a close button are displayed.

FIG. 6A is a diagram schematically illustrating an example of the camera function selection screen displayed in step S301.
In FIG. 6A, on the camera function selection screen, six buttons that can be operated with a touch panel as objects and a captured image as a background image are displayed. When a touch operation is performed at a position where a captured image is displayed, AF and AE can be set to appropriate values for the corresponding coordinates.

  The MENU button 601 is a button for transitioning to the menu screen of the digital video camera 100. On the menu screen, for example, initialization processing of the external recording medium 108 can be selected. A close button 602 is a button for ending the display of the camera function selection screen and returning to the normal camera shooting screen. The AF button 604 is a button for making a transition to the AF adjustment screen. On the AF adjustment screen, for example, an autofocus mode and a manual focus mode can be switched. In the manual focus mode, the focal length can be set manually.

  The AE button 605 is a button for making a transition to the AE adjustment screen. On the AE adjustment screen, for example, the exposure setting of the digital video camera 100 can be changed by adjusting the aperture and the shutter speed. The WB button 606 is a button for making a transition to the WB adjustment screen. On the WB adjustment screen, the color temperature setting can be set to a value that matches a light source such as sunlight or a light bulb. The SHIFT button 603 is a button for switching functions assigned to the AF button 604, the AE button 605, and the WB button 606 described above. When the SHIFT button 603 is touched, the screen shown in FIG. Switch to

  In the camera function selection screen shown in FIG. 6B, the AF button 604 is replaced with the MIC button 607, and the AE button 605 is replaced with the EXP button 608. Further, the WB button 606 is replaced with an EFFECT button 609, and the close button 602 is replaced with a return button 610. At this time, the color of the SHIFT button 603 is changed so that the selected state can be identified.

  The MIC button 607 is a button for transitioning to the MIC adjustment screen for adjusting the volume of the sound input from the microphone unit 208. The EXP button 608 is a button for transitioning to an exposure correction setting screen for setting an exposure correction value. On the exposure correction setting screen, it is possible to set whether the exposure is brighter or darker than the reference value when the AE is automatically exposed.

  The EFFECT button 609 is a button for making a transition to the effect processing setting screen. On the effect processing setting screen, for example, effects can be applied to captured images such as fade-in, wipe, and mosaic processing. The return button 610 is a button for returning to the camera function selection screen shown in FIG.

  Returning to the description of FIG. 3, in step S302, the CPU 101 functions as a setting unit, and sets a standard reaction region for each button displayed in step S301.

FIG. 7 is a diagram showing a reaction area set for each button displayed on the camera function selection screen.
As shown in FIG. 7, reaction areas 701 to 706 are set for each button displayed on the camera function selection screen. Note that the reaction areas 701 to 706 shown in FIG. 7 are not displayed.

  Next, in step S303, the CPU 101 functions as a detection unit and performs touch detection processing. Here, details of the touch detection process will be described.

FIG. 5 is a flowchart showing an example of a detailed procedure of the touch detection process in step S303 of FIG.
First, in step S501, it is determined whether or not the touch panel of the display 204 is touched. If the result of this determination is that there is no touch, the process proceeds to step S506, and if it is touched, the process proceeds to step S502.

  In step S502, the touch position is detected. In step S503, it is determined whether or not the touch position detected in step S502 is within the reaction regions 701 to 706 shown in FIG. If the result of this determination is that the touch position is within the reaction areas 701 to 706, in step S504, the button in which the corresponding reaction area is set is set to the selected state.

  On the other hand, as a result of the determination in step S503, if the touch position is outside the reaction areas 701 to 706, the process proceeds to step S505. In step S505, it is determined that the captured image displayed as the background image has been touched, and the background image is set to the selected state. In step S506, a button (and a background image) that is not set to the selected state is set as a non-selected state, and the touch detection process ends.

  Returning to the description of FIG. 3, next, in step S304, it is determined whether or not the SHIFT button 603 is set to the selected state by the touch detection processing in step S303. As a result of the determination, if the SHIFT button 603 is set to the selected state, the process proceeds to step S401 in FIG. 4, and if not, the process proceeds to step S305.

  Next, in step S305, it is determined whether or not the AF button 604 is set to the selected state by the touch detection process in step S303. As a result of this determination, if the AF button 604 is set to the selected state, the process proceeds to step S307, and if not, the process proceeds to step S308. In step S307, the display control unit 104 changes the screen to the AF adjustment screen, and the process on the camera function selection screen is terminated.

  In step S308, it is determined whether or not the AE button 605 is set to the selected state by the touch detection process in step S303. As a result of the determination, if the AE button 605 is set to the selected state, the process proceeds to step S309, and if not, the process proceeds to step S310. In step S309, the display control unit 104 changes the screen to the AE adjustment screen, and the process on the camera function selection screen is terminated.

  In step S310, it is determined whether or not the WB button 606 is set to the selected state by the touch detection process in step S303. As a result of this determination, if the WB button 606 is set to the selected state, the process proceeds to step S311; otherwise, the process proceeds to step S312. In step S311, the display control unit 104 changes the screen to the WB adjustment screen, and the process on the camera function selection screen is terminated.

  In step S312, it is determined whether or not the MENU button 601 is set to the selected state by the touch detection process in step S303. As a result of this determination, if the MENU button 601 is set to the selected state, the process proceeds to step S313, and if not, the process proceeds to step S314. In step S313, the display control unit 104 changes the screen to the MENU screen and ends the camera function selection screen.

  In step S314, it is determined whether or not the close button 602 is set to the selected state by the touch detection process in step S303. As a result of this determination, if the close button 602 is set to the selected state, the process proceeds to step S315, and if not, the process proceeds to step S316. In step S315, the display control unit 104 makes a transition to the camera recording screen, and the process on the camera function selection screen is terminated.

  In step S316, it is determined whether or not the background image is set to the selected state by the touch detection process in step S303. As a result of this determination, if the background image is set to the selected state, the process proceeds to step S317, and if not, the process returns to step S303 and the touch detection process is performed again. In step S317, the setting of the camera unit 207 is changed so that the values of AE and AF become appropriate values for the selected position of the background image.

  If the SHIFT button 603 is set to the selected state as a result of the determination in step S304, the display control unit 104 performs button change processing in step S401 in FIG. Specifically, the AF button 604 is changed to the MIC button 607, and the AE button 605 is changed to the EXP button 608. Further, the WB button 606 is changed to an EFFECT button 609, and the close button 602 is changed to a return button 610.

  In step S402, the reaction area of the MIC button 607, the EXP button 608, the EFFECT button 609, and the return button 610 is enlarged, and the reaction area of the MENU button 601 is reduced. Thereby, the reaction area of each button is changed from the area indicated by the broken line 801 shown in FIG. 8A to the area indicated by the broken line 802 shown in FIG.

  When the SHIFT button 603 is touched, the user is likely to select a selection item that is not displayed on the screen. Therefore, since any of the newly displayed MIC button 607, EXP button 608, and EFFECT button 609 is likely to be touched, the reaction area of these buttons is expanded in this embodiment. In addition, there is a possibility that the button intended by the user is not included in the newly displayed button. Therefore, the reaction area is expanded also for the return button 610.

  On the other hand, since the MENU button 601 is a button that can be selected without touching the SHIFT button 603, the possibility of being touched by the user is low. Therefore, the reaction area of the MENU button 601 is reduced. As described above, in this embodiment, the CPU 101 functions as a selection unit, and selects a button for enlarging a reaction area and a button for reducing a reaction area.

  Next, in step S403, the touch detection process shown in FIG. 5 is performed by the same procedure as in step S303. In step S404, it is determined whether or not the MIC button 607 is set to the selected state by the touch detection process in step S403. As a result of this determination, if the MIC button 607 is set to the selected state, the process proceeds to step S405, and if not, the process proceeds to step S406. In step S405, the display control unit 104 changes the screen to the MIC adjustment screen, and the process on the camera function selection screen is terminated.

  In step S406, it is determined whether or not the EXP button 608 is set to the selected state by the touch detection process in step S403. As a result of this determination, if the EXP button 608 is set to the selected state, the process proceeds to step S407, and if not, the process proceeds to step S408. In step S407, the display control unit 104 changes the screen to the EXP adjustment screen, and the process on the camera function selection screen is terminated.

  In step S408, it is determined whether or not the EFFECT button 609 is set to the selected state by the touch detection process in step S403. As a result of the determination, if the EFFECT button 609 is set to the selected state, the process proceeds to step S410, and if not, the process proceeds to step S409. In step S409, the display control unit 104 changes the screen to the EFFECT selection screen, and the process on the camera function selection screen is terminated.

  In step S410, it is determined whether or not the return button 610 is set to the selected state by the touch detection process in step S403. As a result of this determination, if the return button 610 is set to the selected state, the process proceeds to step S411, and if not, the process returns to step S403. In step S411, the display control unit 104 performs button change processing from the state shown in FIG. 6B to the state shown in FIG. Specifically, the MIC button 607 is changed to the AF button 604, and the EXP button 608 is changed to the AE button 605. Then, the EFFECT button 609 is changed to the WB button 606, and the return button 610 is changed to the close button 602. At this time, the selected state of the SHIFT button 603 is canceled.

  By performing the above processing, for buttons that can be selected only after selecting a specific button, or for buttons whose functions change after a specific button is selected, the touch response area is expanded and displayed. The reaction area of the remaining buttons was narrowed. Thereby, the operativity of a touch can be improved with respect to the button expected to be operated next by the user. Further, by enlarging only the reaction region, it is possible to prevent a background image such as a captured image from being hidden by enlarging the button, and to improve operability. Further, for example, when the touch panel is operated with a finger, the reaction region is present at a position close to the finger touching the SHIFT button, so that the operability can be further improved.

  In the present embodiment, when the SHIFT button 603 is touched and the background image is touched when the camera function selection screen shown in FIG. 6B is displayed, as in step S317 in FIG. You may make it set the value of AE and AF to an appropriate numerical value.

(Second Embodiment)
In the present embodiment, an example will be described in which, in the processing in the first embodiment, the amount of enlargement of the reaction region is determined using a detection shift when the button is further touched. The configuration of the digital video camera according to the present embodiment is the same as that shown in FIGS. Also, the processing procedure when the touch panel is operated on the camera function selection screen is different in that processing in steps S901 and S902 in FIG. 9 described later is performed instead of step S402 in FIG. Only differences from the first embodiment will be described below.

FIG. 9 is a flowchart illustrating an example of a processing procedure when the touch panel is operated when the SHIFT button 603 is set to the selected state in the present embodiment. Each process shown in FIG. 9 is performed under the control of the CPU 101.
In step S901, a displacement amount and a displacement direction between the position where the touch is detected and the center position of the SHIFT button 603 are detected.

FIG. 10 is a diagram for explaining the center position and the shift amount of the SHIFT button 603.
In FIG. 10, when the SHIFT button 1001 is touched with the stylus pen 1003 or the like and a touch is detected at the coordinates 1004, the CPU 101 detects a vector 1005 indicating a shift amount and a shift direction from the center position 1002.

  In step S902, the reaction area of the MIC button 607, the EXP button 608, the EFFECT button 609, and the return button 610 is enlarged, and the reaction area of the MENU button 601 is reduced. Hereinafter, a method for expanding the reaction region at this time will be described with reference to FIG.

FIG. 11 is a diagram for explaining how the reaction region of the MIC button 607 is enlarged.
In FIG. 11, a standard reaction area 1101 is set for the MIC button 607. With respect to the standard reaction area 1101, a reaction area 1102 enlarged according to the vector 1005 indicating the shift amount and the shift direction from the center of the SHIFT button 603 calculated in step S 901 is set as the reaction area of the MIC button 607. In the present embodiment, since the touch position is shifted from the center position to the upper left side, the upper left side of the reaction region is enlarged.

FIG. 12 is a diagram for explaining how the reaction area is enlarged on the camera function selection screen.
As shown in FIG. 12, in accordance with a vector 1005 indicating the amount of displacement and the direction of displacement from the center of the SHIFT button 603, the EXP reaction region 1201 is similarly set to an enlarged reaction region 1202 for the EXP button 608. The EFFECT button 609 is also set to the reaction area 1204 in which the standard reaction area 1203 is enlarged, and the return button 610 is also set to the reaction area 1206 in which the standard reaction area 1205 is enlarged. However, since a part of the reaction area 1206 of the return button 610 protrudes from the touch panel and the outside of the touch panel cannot be touched, the hatched portion 1207 that is within the touch panel range is set as the reaction area.

  As described above, according to the present embodiment, when a specific button called the SHIFT button 603 is selected, the shift amount and the shift direction from the center position are detected, and the reaction region is expanded in the shift direction according to the shift amount. . Thereby, it is possible to improve the operability of the touch operation in consideration of the deviation of the same touch operation with respect to the button expected to be operated next by the user.

  In the present embodiment, the coordinate error is calculated from the shift in the last single touch operation. However, the coordinate error may be calculated based on the shift of the past multiple touch operations. In that case, the amount of deviation may be calculated from the average value or intermediate value of errors, and any calculation method may be used.

  In the present embodiment, the reaction area is expanded by applying the calculated shift amount as it is, but the reaction area may be expanded using an appropriate ratio. Further, when the reaction region is expanded by the calculated amount of deviation, an upper limit may be provided for the expansion so as not to overlap with the adjacent reaction region.

(Other embodiments)
In the embodiment described above, the camera function selection screen of the digital video camera has been described as a preferred example. However, the present invention is not limited to this, and can be applied to a screen having other functions of the digital video camera. Furthermore, the present invention can be similarly applied to any display device using a touch panel such as a mobile phone, a digital still camera, a car navigation system, and a digital photo frame. The present invention can also be applied to a multi-touch touch panel.

  The present invention can also be realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, or the like) of the system or apparatus reads the program. It is a process to be executed.
