[Image display]
Next, an image display method in the electronic apparatus 1 according to the present embodiment will be described with reference to FIGS.
FIG. 2 is an image diagram showing a display example of an image according to the present embodiment.
Hereinafter, a case where the through image I captured by the imaging unit 102 is displayed will be described as an example.
As shown in the figure, when there is no user's hand on the display area of the display unit 105, the control unit 101 displays the through image I on the entire display area of the display unit 105. That is, the control unit 101 displays the through image I in the entire display area of the display unit 105 when no touch is detected on the touch panel 106. At this time, the control unit 101 determines the gravity direction based on the detection result of the posture detection unit 107, and displays the through image I so that the gravity direction is downward.

FIG. 3 is an image diagram showing a display example of an image when the user's hand covers the display area according to the present embodiment.
As shown in the figure, when the user's hand U covers a part of the display area of the display unit 105, the control unit 101 reduces the through image I to an area not covered by the user's hand U. To display. That is, when the touch panel 106 detects contact, the control unit 101 reduces the through image I in a region where the touch panel 106 does not detect contact. At this time, the control unit 101 displays the size of the through image I in accordance with the size of the area where the touch panel does not detect contact. Further, the control unit 101 displays an operation button such as the menu button B in the display area of the display unit 105 where the user's hand is not in contact and the through image I is not displayed. . The menu button B is a button for displaying a menu for setting imaging conditions and the like.

Note that when the user's hand U moves away from the display area of the display unit 105 and the touch panel 106 no longer detects contact, the control unit 101 enlarges the through image I and displays it on the entire display area of the display unit 105.
When the control unit 101 detects that the user's hand U has moved on the display area, the control unit 101 changes the display of the through image I and the menu button B in accordance with the movement of the user's hand U. That is, the control unit 101 moves the through image I and the menu button B to an area where the touch panel 106 does not detect contact.

FIG. 4 is an image diagram showing a display example of an image when the user's hand covers the display area according to the present embodiment. FIG. 4 is a display example when the electronic device 1 is rotated 90 degrees counterclockwise from the state shown in FIG.
As shown in the figure, the control unit 101 rotates the through image I and the menu button B 90 degrees to the right so that the direction of gravity is downward, and displays it on the display unit 105. At this time, the control unit 101 displays the through image and the menu button B in an area where the touch panel 106 does not detect contact in the display area of the display unit 105.

FIG. 5 is a flowchart showing a procedure of image display processing according to the present embodiment.
First, the control unit 101 determines the direction of gravity based on the detection result of the posture detection unit 107 (step S101). Next, the control unit 101 determines the display direction of the through image I based on the determined gravity direction (step S102). Specifically, the control unit 101 determines the display direction of the through image I so that the gravity direction is downward.
Next, the control unit 101 determines whether there is a contact area on the touch panel 106 (step S103). The contact area is an area where the touch panel 106 detects contact.

When there is no contact area on the touch panel 106 (step S103: No), the control unit 101 displays the through image I in the entire display area of the display unit 105 (step S107).
On the other hand, when there is a contact area on the touch panel 106 (step S103: Yes), the control unit 101 sets an area other than the contact area as an image display area (step S104). That is, the control unit 101 sets a rectangular area having the largest area among areas where the touch panel 106 does not detect contact as an image display area. However, the aspect ratio of the rectangular image display area is equal to the aspect ratio of the rectangular display area in the display unit 105.
Then, the control unit 101 reduces the through image I according to the size of the image display area, and displays the reduced through image I in the image display area (step S105).
Finally, the control unit 101 may display the menu button B or the like in an area where the touch panel 106 does not detect contact and other than the image display area (step S106).

In the present embodiment, the case where the through image I is displayed has been described as an example. However, when the image data of a still image or the image data of a moving image is displayed, similarly, the touch panel 106 does not detect contact. Display an image.
In this embodiment, the menu button B is displayed in an area other than the image display area where the touch panel 106 does not detect contact, but the menu button B is displayed over the through image I. For example, the position where the menu button B is displayed may be an area where the touch panel 106 does not detect contact.

  As described above, according to the present embodiment, since the image is displayed in the area where the touch panel 106 does not detect contact, the entire image is displayed even when the user's hand covers the display area of the display unit 105. Can be displayed. In addition, since the operation button is displayed in an area where the touch panel 106 does not detect contact, the operation button is not covered by the user's hand and cannot be operated. In addition, it is possible to prevent an operation button from being accidentally pressed by a hand holding the electronic device 1.

[Shooting operation]
Next, with reference to FIG. 6 and FIG. 7, a photographing operation in a state where the through image I is displayed in a reduced size will be described. 6 and 7 are diagrams for explaining the photographing operation according to the present embodiment.
First, a photographing operation when the through image I is displayed in the entire display area will be described. When the through image I is displayed in the entire display area, when the user touches an area in the displayed image where the imaging unit 102 is to be focused, the imaging unit 102 focuses on the touched area. Capture the subject. That is, when the touch panel 106 detects a touch while displaying the through image in the entire display area, the control unit 101 captures an object (area) displayed at the position where the touch is detected so that the object (area) is in focus. The unit 102 is controlled to generate still image data.

  However, when the through image I is displayed in a reduced size, if an attempt is made to take a picture with the same operation, the displayed through image I is smaller than that displayed in the entire display region. Compared to the case where the through image I is displayed, it is difficult to specify a position to be focused. For this reason, in the electronic device 1 according to the present embodiment, when the through image I is displayed in a reduced size, when the user touches the area A1 in the image display area of the through image I (see FIG. 6), the electronic device 1 is touched. The through image I is enlarged around the area A1 and partially displayed in the display area (see FIG. 7). The enlargement ratio of the through image I at this time is equal to the enlargement ratio when the through image I is displayed in the entire display area. By enlarging and displaying the through image I, the user can easily specify a position to be focused. When the user touches the object A2 to be focused, the imaging unit 102 focuses on the touched object A2 and images the subject.

  That is, when the touch panel 106 detects contact in the image display area of the through image I while the through image I is being displayed in a reduced size, the control unit 101 enlarges the through image I around the position A1 where the contact is detected. To partially display in the image display area. Then, when the touch panel 106 detects contact again in the image display area, the control unit 101 controls the imaging unit 102 so that the object A2 displayed at the position where the contact is detected is in focus, and the image data of the still image is displayed. Is generated.

  In the present embodiment, when the through image I is displayed in the entire display area, the control unit 101 captures the subject by focusing on the contact position at the first contact, but the through image I is displayed. Similarly to the case where the image I is reduced and displayed, the through image I may be enlarged and displayed by the first contact, and the contact position may be focused by the second contact.

  As described above, according to the present embodiment, when the through image I is displayed in a reduced size, the control unit 101 enlarges and displays the through image I by the first contact in the image display region. The imaging unit 102 is caused to capture an image so that the contact position is focused on the second contact. As a result, even when the through image I is displayed in a reduced size, it is possible to easily specify the position to be focused by a simple operation.

[Menu screen display]
Next, with reference to FIG. 8, the display method of the menu screen in the electronic apparatus 1 according to the present embodiment will be described. FIG. 8 is a diagram for explaining the menu screen display method according to the present embodiment.
The control unit 101 displays, on the display unit 105, an identification display (hereinafter, referred to as an icon) for causing, for example, processing 1 to processing 6 on the menu screen. At this time, when there is a contact area on the touch panel 106, the control unit 101 displays each icon in an area other than the contact area. That is, the control unit 101 displays each icon in an area where the touch panel 106 does not detect contact.

  Thus, according to the present embodiment, the control unit 101 displays an icon in an area where the touch panel 106 does not detect contact. For this reason, even if a part of the display area is covered with a hand, it can be displayed so that all the icons can be seen. In addition, it is possible to prevent the icon from being accidentally pressed with the hand held by the electronic device 1.
