Image pickup device and image pickup method

1. An image pickup device comprising:

a camera;

a display configured to display an image captured by the camera;

a touch panel that overlaps the display; and

a vertical sensor configured to detect an orientation of a vertical direction in the image pickup device,

wherein, when a single touch operation moving on the touch panel upwardly along the orientation of the vertical direction in the image pickup device detected by the vertical sensor is performed while the display is displaying the image, a brightness of the display is changed from a first brightness to a second brightness that is brighter than the first brightness while the display is displaying the image.

2. The image pickup device according to claim 1 , wherein

the display has a rectangular shape, and

the single touch operation moving on the touch panel upwardly along the orientation of the vertical direction in the image pickup device detected by the vertical sensor corresponds to a single touch operation along a short direction of the rectangular shape.

3. The image pickup device according to claim 1 , wherein

the single touch operation moving along the surface of the touch panel upwardly along the orientation of the vertical direction in the image pickup device detected by the vertical sensor is defined as a first touch operation, and

when a second touch operation moving on the touch panel downwardly along the orientation of the vertical direction in the image pickup device detected by the vertical sensor is performed, and the brightness of the display is the second brightness, the brightness of the display is changed from the second brightness to the first brightness.

4. The image pickup device according to claim 1 , wherein the image displayed on the display is a video image.

5. The image pickup device according to according to claim 1 , wherein

the display is a liquid crystal display with a backlight, and

the brightness of the display is changed by changing the brightness of the backlight.

6. The image pickup device according to claim 1 , wherein

the display is a display in which each pixel emits self-luminous light, and

the brightness of the display is changed by changing the brightness of the self-luminous light.

7. The image pickup device according to claim 1 , further comprising:

a housing comprising a first surface and a second surface opposite to the first surface,

wherein the camera is provided on the first surface, and

the display and the touch panel are provided on the second surface.

8. The image pickup device according to claim 1 , further comprising:

a housing comprising a first surface and a second surface opposite to the first surface,

wherein the camera, the display and the touch panel are provided on the first surface.

9. The image pickup device according to claim 1 , wherein, when the single touch operation is performed in a direction transverse to the orientation of the vertical direction in the image pickup device detected by the vertical sensor, the brightness of the display remains the first brightness.

10. The image pickup device according to claim 1 , wherein the vertical sensor is distinct from the touch panel.

11. An image pickup method used in an image pickup device comprising a camera, a display configured to display an image captured by the camera, a touch panel that overlaps the display, and a vertical sensor configured to detect an orientation of a vertical direction in the image pickup device, the image pickup method comprising:

changing a brightness of the display from a first brightness to a second brightness that is brighter than the first brightness while the display is displaying the image, when a single touch operation moving on the touch panel upwardly along the orientation of the vertical direction in the image pickup device detected by the vertical sensor is performed while the display is displaying the image.

12. A non-transitory computer readable recording medium storing an image pickup program used in an image pickup device including a camera, a display configured to display an image captured by the camera, a touch panel that overlaps the display, and a vertical sensor configured to detect an orientation of a vertical direction in the image pickup device, the image pickup program causes a processor to perform:

changing a brightness of the display from a first brightness to a second brightness brighter than the first brightness while the display is displaying the image, when a single touch operation moving on the touch panel upwardly along the orientation of the vertical direction in the image pickup device detected by the vertical sensor is performed while the display is displaying the image.

13. A server comprising the non-transitory computer readable recording medium according to claim 12 , wherein the image pickup program is stored in the server to be downloadable from the server.
