Description

  The present invention relates to an imaging device provided with a touch panel.

  In recent years, portable devices with a photographing function (photographing devices) such as digital cameras have become widespread. Some types of photographing apparatuses have a display unit and a function of displaying a photographed image. Some display screens display a menu screen to facilitate operation of the photographing device. In addition, there is a display device in which a touch panel is arranged so that the photographing apparatus can be operated by a touch operation on the touch panel.

  Such a display unit is often provided on the back surface of the mobile device body, and the user can also perform a shooting operation while confirming a through image displayed on the display unit on the back side during shooting. Further, for example, a finder (eyepiece) may be provided on the upper surface of the photographing apparatus main body. In single-lens digital cameras, digital video cameras, and the like, a finder (eyepiece) is provided to check the composition of an image and the timing of shooting, and many users take pictures while looking through the finder.

  In particular, when the surroundings are bright and the visibility of the display unit on the back is deteriorated, the image is taken through the viewfinder. Also, in a single-lens digital camera, when a large lens is attached, the image is taken while looking through the viewfinder.

  However, when looking through the viewfinder, the display unit on the back cannot be seen, and it is difficult to directly touch an icon or the like displayed on the display unit on the back. For this reason, even when taking a picture while looking through the viewfinder, if it is necessary to operate the touch panel of the display unit for mode switching or setting value change operation, it is necessary to keep an eye on the viewfinder for the operation. There is a risk of missing.

  Therefore, Patent Document 1 proposes an apparatus that facilitates touch operation of the display unit while peeking through the finder by attaching uneven marks to the frame.

  As will be described later, the display unit 35 includes a display screen 35a that displays a captured image. A touch panel 36 is provided on the display screen 35a. The touch panel 36 can generate an operation signal corresponding to the position on the display screen 35a pointed by the user with a finger. This operation signal is supplied to the signal processing and control unit 11. As a result, when the user touches or slides on the display screen 35a, the signal processing and control unit 11 performs a user touch position, an operation of separating a finger, a position reached by a slide operation or a slide operation, Various operations such as a sliding direction and a touch period can be detected, and processing corresponding to a user operation can be executed.

  In addition, the main body unit 10 is provided with an eye sensor 17 that detects that the user has brought the eye close to the eyepiece display unit 31. Based on the detection result of the eye sensor 17, the signal processing and control unit 11 can determine whether or not the user has brought the eye close to the eyepiece display unit 31.

  The display unit 35 is arranged so as to occupy substantially the entire rear surface of the main body unit 10 (see FIG. 2B), and the photographer can display the display unit (hereinafter also referred to as a rear display unit) during shooting. ) A through image displayed on the display screen 35a of 35 can be confirmed, and a shooting operation can be performed while confirming the through image.

  The signal processing and control unit 11 may display the through image on the eyepiece display unit 31 or the rear display unit 35. Thus, the user can take a picture while looking through the eyepiece display unit 31 and confirming the through image, or can take a picture while confirming the through image displayed on the rear display unit 35.

  In the present embodiment, when the user takes a picture while looking into the eyepiece display unit 31, an eyepiece photographing mode in which the state of the user operation on the rear display unit 35 is displayed on the eyepiece display unit 31 can be set. It has become.

In order to enable such an eyepiece photographing mode, the signal processing and control unit 11 includes a display control unit 11a, an eyepiece determination unit 11b, a mode setting unit 11c, a touch position determination unit 11d, and an operation determination unit 11e.
The eyepiece determination unit 11b determines whether or not the user is eyepiece based on the output of the eye sensor 17. The mode setting unit 11c sets the eyepiece shooting mode when the user is eyepiece. In the eyepiece photographing mode, the display control unit 11a displays a through image on the eyepiece display unit 31 and displays operation displays for various settings on the eyepiece display unit 31. For example, the display control unit 11a can display a menu display using a plurality of operation icons corresponding to each operation as the operation display.

  In the present embodiment, in the eyepiece display mode, the signal processing and control unit 11 receives an operation on the touch panel 36 in the same manner as when the display similar to the display on the operation eyepiece display unit 31 is displayed on the rear display unit 35. For example, when a touch operation is performed on the touch panel 36 provided on the rear display unit 35, the signal processing and control unit 11 displays an operation display of the position of the eyepiece display unit 31 corresponding to the touch position of the rear display unit 35. Control is performed as if a touch operation was performed.

  The touch position determination unit 11d detects a position where the user touches the back display unit 35. The operation determination unit 11e detects the user's operation based on the contact, separation, slide operation, and the like of the finger on the user's rear display unit 35. For example, the operation determination unit 11e causes the user to display an operation display on the eyepiece display unit 31 corresponding to a specific position of the back display unit 35 by an operation in which the user continuously touches the same position of the back display unit 35 for a predetermined time. It is determined that the operation is to be selected. After the operation, when the user moves his / her finger away from the rear display unit 35, the operation determination unit 11e determines that the user has confirmed the selection. Further, when the user slides his / her finger on the rear display unit 35 and moves the finger away from the rear display unit 35 without stopping at the same position for a predetermined time, the user cancels the previous operation. It is determined that the operation has been performed.

  When the operation determination unit 11e indicates that the user is performing a selection operation, the touch position determination unit 11d outputs a detection result of the user's touch position to the display control unit 11a. In this case, the display control unit 11a makes it possible to distinguish the display of the operation display at the position corresponding to the touch position from other displays according to the detection result of the touch position. For example, the operation display at the position corresponding to the touch position is highlighted, and the color, darkness, shape, pattern, etc. are changed with respect to the operation display at other positions.

  The mode setting unit 11c receives outputs from the touch position determination unit 11d and the operation determination unit 11e, and changes the mode according to the user's touch operation.

  2 to 6 are explanatory diagrams for explaining the eyepiece photographing mode in the present embodiment. 2A and 2B are explanatory views showing the appearance of the photographing apparatus 1 during photographing. FIG. 2A shows the front side, and FIG. 2B shows the rear side. FIG. 3 is an explanatory diagram showing how to hold the photographing device 1 during photographing.

  In the present embodiment, for example, the eyepiece display unit 31 is used when checking the composition before shooting and the timing of shooting, and the touch panel 36 provided on the rear display unit 35 is operated by blind touch, thereby switching modes, etc. Is supposed to do.

  As shown in FIGS. 2A and 3A, the photographer 41 normally supports the interchangeable lens 20 with his left hand 41L, and gently touches the index finger 42a on the release switch 51 on the upper surface of the main body 10 while the main body 10 Is held lightly by the right hand 41R. When viewed from the back in this posture, a through image (live view image) 52 is displayed on the display screen 35a of the rear display unit 35 of the main body unit 10 as shown in FIG. 41R has its index finger 42a positioned on the release switch 51 on the upper surface of the main body 10, and its thumb 42b is positioned in the right region (as viewed by the photographer) of the rear display unit 35. Therefore, the photographer can naturally touch the area on the right side of the touch panel 36 on the rear display unit 35 with the thumb 42b of the right hand, and various operations such as mode switching can be performed by touch operations such as touch and slide.

  As shown in FIG. 3B, it is possible to perform a shooting operation while confirming the through image displayed on the rear display unit 35. In this case, for example, the touch panel 36 can be operated while viewing the display screen 35a with the index finger 42a of the right hand 41R.

  On the other hand, as shown in FIG. 3A, the display screen 35a of the rear display unit 35 cannot be viewed in a state in which the eyepiece display unit 31 is viewed in order to confirm the composition of the viewfinder image and the timing of shooting. . However, as described above, even in this case, the thumb 42b of the right hand 41R can blind-touch the touch panel 36.

  Therefore, in the present embodiment, in order to perform the operation reliably even by the blind touch of the touch panel 36, the operation display is displayed on the display screen 31a of the eyepiece display unit 31, and the touch operation status of the touch panel 36 is also displayed. It is supposed to be displayed.

  FIG. 4 is an explanatory diagram for explaining the screen display when the mode is set.

  When the determination result of the eyepiece determination unit 11b indicates that the user does not have an eyepiece, for example, an operation display illustrated in FIG. 4A is displayed. When the user does not have an eye, the display control unit 11a displays the through image 52 on the display screen 35a of the rear display unit 35. Further, the display control unit 11a displays an operation display 61 on the display screen 35a. In the example of FIG. 4, the operation display 61 has three operation icons 61a to 61c, and each operation icon 61a to 61c is for setting a program mode (P), a strobe mode (St), and an exposure adjustment (±), respectively. belongs to.

  For example, when the user touches one of the operation icons 61a to 61c on the display screen 35a with the index finger 42a of the right hand 41R, a mode corresponding to the touched icon is set. For example, by touching the operation icon 61a, a sub menu for selecting a program mode, a shutter priority mode, and an aperture priority mode can be displayed.

  Further, for example, by touching the operation icon 61b, a submenu for selecting on / off of flash emission and automatic setting can be displayed. For example, the exposure setting mode can be set by touching the operation icon 61c.

  On the other hand, when the determination result of the eyepiece determination unit 11b indicates that the user is in contact with the eye, the operation display shown in FIG. 4B is displayed. When the user is in eye contact, the display control unit 11 a displays the through image 52 on the display screen 31 a of the eyepiece display unit 31. In addition, the display control unit 11a displays an operation display 61 on the display screen 31a.

  In the present embodiment, by operating the touch panel 36 on the rear display unit 35, the operation on the operation icons 61a to 61c of the operation display 61 displayed on the display screen 31a of the eyepiece display unit 31 is performed. to enable.

  When the user touches the touch panel 36 with the thumb 42b of the right hand 41R, the touch position determination unit 11d detects a position where the user touches the rear display unit 35. When the operation determination unit 11e determines that the user's touch operation is an operation icon selection operation, the display control unit 11a displays an operation icon arranged on the eyepiece display unit 31 at a position corresponding to the user's touch position. As the selected item, the operation icon is displayed differently from the other icons. For example, as shown in FIG. 4B, when the user touches the lower area of the upper, lower, and center of the display screen 35a, the display control unit 11a is arranged below the display screen 31a. Assuming that the operation icon 61c is selected, the operation icon 61c is displayed in a thick frame.

  Furthermore, for example, when the user slides his / her finger without separating it from the touch panel 36, the user can select another operation icon. For example, when the user slides the thumb 42b to the center position, the display control unit 11a displays a thick frame assuming that the operation icon 61b arranged at the center of the display screen 31a is selected.

  As illustrated in FIG. 4C, the operation determination unit 11 e determines that the selected operation has been confirmed by performing an operation in which the user moves the thumb 42 b away from the touch panel 36. For example, when the thumb 42b is separated from the touch panel 36 in the state of FIG. 4B, the mode setting unit 11c determines that the operation for confirming the transition to the exposure setting mode has been performed, and sets the exposure setting mode.

  As shown in FIG. 4C, when the user slides the thumb 42b away from the touch panel 63, the operation determination unit 11e determines that the selection operation has been released.

  As described above, in the present embodiment, when the user touches the eye, the mode is determined by a touch operation on the operation icon. On the other hand, when the user does not touch the eye, touch, separation, slide, etc. By detecting this operation, the mode is determined, and the operation status is displayed on the eyepiece display unit 31, so that a reliable operation can be performed even with the touch of the mind.

  4 shows an example in which an operation display is displayed on the display screen 35a of the rear display unit 35 even in the eyepiece shooting mode, the operation display may not be displayed on the display screen 35a. It is clear.

  Furthermore, in the present embodiment, not only a mode selection operation but also a parameter setting operation can be performed by a blind touch on the rear display unit 35. FIG. 5 is an explanatory diagram for explaining the parameter setting operation.

  Now, it is assumed that the user confirms the selection of the operation icon 61c in FIG. Thereby, the mode setting part 11c sets exposure setting mode. In the exposure setting mode, the display control unit 11a displays the through image 52 on the display screen 31a, and displays a parameter setting display 71 as a submenu as an operation display on the right side of the display screen 31a. The parameter setting display 71 includes a level bar display 71a, an operation bar display 71b, and an operation direction display 71c. Further, the display control unit 11a displays a display 72 “exposure correction” indicating the exposure setting mode at the upper left end of the display screen 31a. Further, the display control unit 11a displays a display 73 indicating the current exposure value.

  The through image 52 and these displays 71 to 73 are displayed on the display screen 35a of the rear display unit 35 when the user is not in contact with the eye, and are displayed on the eyepiece display unit 31 when the user is in contact with the eye. It is displayed on the screen 31a. If the user does not have an eye, the user touches the operation bar display 71b displayed on the display screen 35a of the rear display unit 35 and slides it up and down to change the exposure value. Can do. For example, the exposure value can be changed to the plus side by sliding the operation bar display 71b upward, and the exposure value can be changed to the minus side by sliding the operation bar display 71b downward.

  When the user is in the eye, the user cannot visually recognize the parameter setting display 71 on the rear display unit 35. Therefore, in the present embodiment, the touch position determination unit 11d and the operation determination unit 11e determine the change direction and change amount of the exposure value based on the slide direction and the slide amount, not the absolute position of the user's thumb 42b. .

  If the user concentrates on photographing, the user may look into the eyepiece display unit 31 as close as possible, and the user's nose may come into contact with the display screen 35 a of the rear display unit 35. Therefore, the central area 65 of the display screen 35a shown in FIG. 5A may be a dead zone (touch invalid area).

  At the time of eyepiece, the user changes the exposure value setting by sliding the thumb 42b of the right hand 41R in the vertical direction indicated by the arrow 66 on the right side of the display screen 35a. It is assumed that the user slides the thumb 42b upward. In this case, the touch position determination unit 11d and the operation determination unit 11e can detect the upward slide and the slide amount. As shown in FIG. 5B, the display control unit 11a displays an operation direction display 71c indicating that the slide direction is upward, and slides the operation bar display 71b upward in accordance with the slide amount. . Further, the display control unit 11a changes the display 73 in accordance with the slide amount, that is, the exposure value change amount.

  The signal processing and control unit 11 controls each unit so that the exposure value changes according to the user's slide operation. Thus, when the user slides the thumb 42b upward, the exposure value can be corrected to the plus side, and a through image 52 with an increased exposure value is obtained as shown in FIG. 5B.

  Conversely, it is assumed that the user slides the thumb 42b downward. In this case, the touch position determination unit 11d and the operation determination unit 11e can detect the downward slide and the slide amount. As shown in FIG. 5C, the display control unit 11a displays an operation direction display 71c indicating that the slide direction is downward, and slides the operation bar display 71b downward according to the slide amount. . Further, the display control unit 11a changes the display 73 in accordance with the slide amount, that is, the exposure value change amount.

  The signal processing and control unit 11 controls each unit so that the exposure value changes according to the user's slide operation. Thus, when the user slides the thumb 42b downward, the exposure value can be corrected to the minus side, and as shown in FIG. 5C, a through image 52 with a reduced exposure value is obtained.

  When the user does not slide the finger or when the finger is separated from the touch panel 36, the exposure value change amount is retained. When the user touches the touch panel 36 again to resume the slide, the exposure value is changed from the previous exposure value according to the slide direction and the slide amount. That is, by repeatedly performing the sliding operation while the user separates the finger, the exposure changing operation can be freely performed regardless of the position where the finger is first touched.

  When the user slides his / her finger in the horizontal direction, the operation determination unit 11e determines that the user's parameter setting operation has been completed, and the mode setting unit 11c displays the original operation display as shown in FIG. Return to 61.

  Next, the operation of the embodiment configured as described above will be described with reference to the flowchart of FIG. FIG. 6 is a flowchart for explaining photographing control.

  When the photographing apparatus 1 is powered on, the signal processing and control unit 11 starts displaying a through image in step S1 of FIG. That is, the signal processing and control unit 11 takes a captured image from the imaging unit 12 and performs predetermined video signal processing on the captured image. Based on the output of the eye sensor 17, the eyepiece determination unit 11b of the signal processing and control unit 11 determines whether or not the user has brought the eye close to the eyepiece display unit 31 (step S2). The display control unit 11a determines whether to display the through image on the rear display unit 35 or the eyepiece display unit 31 based on the determination result of the eyepiece determination.

  When the user does not bring his eyes close to the eyepiece display unit 31, the display control unit 11a gives the captured image subjected to signal processing to the rear display unit 35 to display a through image. Further, the display control unit 11a causes the rear display unit 35 to display a menu display such as mode switching shown in FIG.

  For the menu display displayed on the rear display unit 35, the user can directly touch the menu portion of the touch panel 36 to select a menu item and change the mode (steps S4 and S5).

  On the other hand, when the user has an eye on the eyepiece display unit 31, the display control unit 11 a gives the captured image subjected to signal processing to the eyepiece display unit 31 to display a through image. Further, the display control unit 11a displays a menu display such as mode switching shown in FIG. 4 on the eyepiece display unit 31 (step S10).

  In this case, for example, as shown in FIG. 3A, the user brings his eyes close to the eyepiece display unit 31 for photographing, and it is difficult to confirm the display on the rear display unit 35. However, since the thumb 42b of the right hand 41R can easily touch and operate the area on the right side of the display screen 35a of the rear display unit 35, the operation for the menu display displayed on the display screen 31a of the eyepiece display unit 31 is performed on the rear surface. The touch panel 36 provided on the display unit 35 is used. Further, in order to enable a reliable operation, the operation status is displayed on the display screen 31 a of the eyepiece display unit 31 in accordance with an operation such as a user touch.

  In step S12, the operation determination unit 11e determines whether the user has performed a touch operation. When the touch operation is performed, the display control unit 11a performs, for example, highlighting indicating that the operation icon at the corresponding position is selected according to the touch position detected by the touch position determination unit 11d (Step S1). S12).

  The operation determination unit 11e determines whether or not a vertical slide operation has been performed in Step S13, and determines whether or not a horizontal slide operation has been performed in Step S15. When the operation determination unit 11e detects a vertical slide operation, the display control unit 11a changes the selected position and highlights the corresponding operation icon according to the touch position detected by the touch position determination unit 11d. When the operation determination unit 11e detects a lateral slide operation, the signal processing and control unit 11 determines that the selection operation has been released.

  In step S <b> 16, the operation determination unit 11 e determines an operation for moving the finger away from the touch panel 36. The mode setting unit 11c determines that the separation operation is a confirmation operation of the selection operation, and sets the mode assigned to the operation icon corresponding to the touch position before separation detected by the touch position determination unit 11d (step S17). ).

  For example, when the parameter setting is necessary after the mode is selected as in the exposure setting mode (step S18), the parameter setting display is displayed as a submenu next to the menu display for mode setting (step S19). For example, when a submenu such as a parameter setting display shown in FIG. 5 is displayed, the operation determination unit 11e determines whether or not a vertical slide operation has been performed in step S20, and whether or not a horizontal slide operation has been performed in step S22. Determine whether or not.

  When the operation determination unit 11e detects a vertical slide operation, the display control unit 11a changes the display position for parameter change according to the change in the touch position detected by the touch position determination unit 11d. Further, the signal processing and control unit 11 changes the parameter according to the change of the touch position detected by the touch position determination unit 11d (step S21). That is, when the user slides his / her finger up and down, the parameter can be increased / decreased and the display of the parameter value can be changed and displayed on the display screen 31 a of the eyepiece display unit 31.

  When the operation determination unit 11e detects a horizontal slide operation, the display control unit 11a determines that the parameter setting operation has been completed, and displays a menu display on the eyepiece display unit 31 (step S23).

  In step S24, the signal processing and control unit 11 determines whether or not a release operation is performed. When the release operation is performed, the signal processing and control unit 11 performs autofocus (AF) and exposure control (AE) (step S24). S25) After the through image is stopped (step S26), photographing is performed (step S27). The signal processing and control unit 11 resumes the through image display in step S28.

  As described above, in this embodiment, when the eyepiece is displayed on the eyepiece display unit, an operation display such as a menu display is displayed on the eyepiece display unit, and an operation on the touch panel provided on the rear display unit is accepted. In this case, the state of the operation can be confirmed on the eyepiece display unit by changing the display of the eyepiece display unit according to the operation of the touch panel. Further, each part of the operation display unit is selected by touching the position of the rear display unit corresponding to the position of each part of the operation display, and an intuitive selection operation is possible. In addition, the combination of touch operation, slide operation, separation operation, etc., determines the selection, confirmation, and release of the operation. Even when performing a blind touch on the touch panel, reliable operation can be performed from the display on the eyepiece display unit. Is possible.

  Moreover, even if the user performs a touch for selection, the operation icon displayed on the eyepiece display unit is not hidden by the finger, and the selected operation icon can be reliably recognized by highlighting or the like. The operability can be remarkably improved.

(Second Embodiment)
FIG. 7 is an explanatory view showing a second embodiment of the present invention. The hardware configuration of this embodiment is the same as that of the first embodiment.

  This embodiment corresponds to not only a one-point touch operation but also a two-point touch operation. FIG. 8 is a flowchart showing touch determination in the present embodiment, which can be used for operation determination of the touch panel 36 in steps S4 and S11 of FIG.

  In step S31 of FIG. 8, the operation determination unit 11e determines whether or not the operation is a one-point touch operation. When a one-point touch operation in which the touch panel 36 is operated with only one finger is performed, the operation determination unit 11e performs the same operation determination as that in the first embodiment. That is, in the case of a one-point touch, a selection operation, a confirmation operation, and the like are performed according to the touch position.

  On the other hand, when the user performs a two-point touch operation, the operation determination unit 11e determines whether a pinch operation has been performed in step S35. The operation determination unit 11e ends the process when the user touches two points and separates the finger without sliding it.

  When the user performs a pinch operation to change the touch position by sliding a finger after the two-point touch, the operation determination unit 11e determines whether or not the pinch operation has been performed at the operation display position in step S36. judge. When a pinch operation is performed at a position other than the operation display position, the operation determination unit 11e determines that the pinch operation is an operation for enlarging or reducing the screen, and the screen is displayed according to the pinch operation. Enlargement or reduction processing is performed (step S37).

  On the other hand, when a pinch operation is performed at the position of the operation display, the operation determination unit 11e determines that the pinch operation is an operation for increasing or decreasing the number of items in the operation display. FIG. 7 shows this operation, and FIG. 7A shows that the user touches two points at the position of the operation display 61 with the index finger 42a and the thumb 42b of the right hand 41R. FIG. 7B shows a pinch operation in which the user narrows the touch interval by sliding the index finger 42a and the thumb 42b in the direction of the arrow. When a pinch operation for narrowing the touch interval is performed, the interval of the operation display 61 is narrowed as indicated by the operation display 61 ′ in FIG. 7B.

  The signal processing and control unit 11 increases the number of operation display items (operation icons), and the display control unit 11a displays the operation icons with an increased number. In the example of FIG. 7C, the operation display 61 includes the operation icon 61d added to the three operation icons 61a to 61c and the operation display 61 including the four operation icons 61a to 61d. The operation icon 61d is for designating a mode for setting the ISO sensitivity.

  7 illustrates the example in which the operation display 61 is displayed on the display screen 35a of the rear display unit 35. However, even when the operation display 61 is displayed on the display screen 31a of the eyepiece display unit 31, A two-point touch operation is possible. Even in this case, the user can change the display of the eyepiece display unit 31 by operating the touch panel 36 provided on the rear display unit 35 as in the first embodiment, and step S36 in FIG. , S38, screen enlargement / reduction processing for the display screen 31a of the eyepiece display unit 31 or processing for increasing / decreasing the number of items in the operation display 61 can be performed.

  As described above, in the present embodiment, the same effects as those of the first embodiment can be obtained, and a two-point touch operation can be handled.

  In the above embodiment, an example has been described in which the number of items that can be displayed on the screen at the same time (three in FIG. 4) is changed by changing the size of the operation icon. In many cases, the display control unit 11a is configured so that the non-displayed items are sequentially displayed cyclically by sliding the finger on the touch panel and positioning the finger at the upper or lower right side of the rear display unit. It is also possible to control by.

  FIG. 9 is an explanatory diagram showing an example of this case. In the example of FIG. 9, the operation icon is slid in the direction of the arrow by touching the lower end of the display screen 35 a with the index finger 42 a (thumb when the eye is attached). By continuously pressing the lower end, the operation icons can be sequentially slid, and the operation icons that are not displayed on the screen can be sequentially displayed in the screen. In this case, highlighting or the like may be performed on the assumption that the operation icon newly displayed is selected. Even in this case, by selecting an operation corresponding to the operation icon highlighted when the finger is separated from the touch panel, the user can surely grasp the operation selected by the user. Even when the number of items is extremely large, a relatively large operation icon can be displayed, and all items can be displayed in order, which is excellent in operability. Further, even when the operation icon is relatively small, the operation icon selected by the user can be reliably recognized, and erroneous operations can be significantly reduced.

  Furthermore, in each embodiment of the present invention, a digital camera has been described as an apparatus for photographing. However, the camera may be a digital single lens reflex camera or a compact digital camera, such as a video camera or a movie camera. A camera for moving images may be used, and a camera built in a personal digital assistant (PDA) such as a mobile phone or a smartphone may of course be used.

  The present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, you may delete some components of all the components shown by embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
