Portable electronic device, display direction switching method, and recording medium
First Claim
1. A portable electronic device characterized by comprising:
- display means (1) for displaying an image in a predetermined display direction;
rotation detection means (11) for detecting a displacement of a housing (20) which stores said display means, from a predetermined posture position by rotation; and
coordinate rotation/transformation means (3) for, when a current posture position of the housing obtained from the rotation displacement detected by said rotation detection means is a first posture position rotated through a predetermined angle from the predetermined posture position in a predetermined direction, rotating the image so as to display the image in a first display direction rotated through 90°
from the predetermined display direction in the predetermined direction.

Abstract
A portable electronic device includes a display, rotation detection unit, and coordinate rotation/transformation module. The display displays an image in a predetermined display direction. The rotation detection unit detects the displacement of a housing which stores the display, from a predetermined posture position by rotation. When the current posture position of the housing obtained from the rotation displacement detected by the rotation detection unit is the first posture position rotated through a predetermined angle from the predetermined posture position in a predetermined direction, the coordinate rotation/transformation module rotates the image so as to display it in the first display direction rotated through 90° from the predetermined display direction in the predetermined direction. A display direction switching method and recording medium are also disclosed.

7. A portable electronic device characterized by comprising:
-
display means (1) for displaying an image in a predetermined display direction;
image size determination means (15) for determining, on the basis of a detection result obtained from a video stream supplied as the image, which of two display directions including the predetermined display direction of video and a first display direction rotated through 90°
from the predetermined display direction in a predetermined direction increases a display area on a screen; and
coordinate rotation/transformation means (3) for rotating the image so as to display the video in the first display direction when determination by said image size determination means represents the first display direction. - View Dependent Claims (8)

9. A method of switching a display direction of a portable electronic device which displays an image in a predetermined display direction, characterized by comprising:
-
the first step of detecting a displacement of a housing (20) of the portable electronic device from a predetermined posture position by rotation; and
the second step of determining a current posture position of the housing on the basis of the rotation displacement detected in the first step, the second step including the third step of rotating the image so as to display the image in a first display direction rotated through 90°
from the predetermined display direction in a predetermined direction, on the basis of determination that the current posture position of the housing is a first posture position rotated through a predetermined angle from the predetermined posture position in the predetermined direction. - View Dependent Claims (10, 11, 12)

13. A method of switching a display direction of a portable electronic device which displays an image in a predetermined display direction, characterized by comprising:
-
the first step of detecting an aspect ratio of video obtained from a video stream supplied as the image; and
the second step of determining, on the basis of the aspect ratio of the video detected in the first step, which of the predetermined display direction of the video and a first display direction rotated through 90°
from the predetermined display direction in a predetermined direction increases a display area on a screen,the second step including the third step of rotating the image so as to display the video in the first display direction, on the basis of determination that the display area on the screen increases in the first display direction.

14. A recording medium which records a program for switching a display direction of a portable electronic device that displays an image in a predetermined display direction, characterized in that the recording medium records a program which causes a computer of the portable electronic device to execute
the first process of detecting a displacement of a housing (20) of the portable electronic device from a predetermined posture position by rotation; -
the second process of determining a current posture position of the housing on the basis of the rotation displacement detected in the first process; and
the third process of rotating the image so as to display the image in a first display direction rotated through 90°
from the predetermined display direction in a predetermined direction, on the basis of determination that the current posture position of the housing is a first posture position rotated through a predetermined angle from the predetermined posture position in the predetermined direction. - View Dependent Claims (15, 16)

17. A recording medium which records a program for switching a display direction of a portable electronic device which displays an image in a predetermined display direction, characterized in that the recording medium records a program which causes a computer of the portable electronic device to execute
the first process of detecting an aspect ratio of video obtained from a video stream supplied as the image, the second process of determining, on the basis of the aspect ratio of the video detected in the first step, which of the predetermined display direction of the video and a first display direction rotated through 90° - from the predetermined display direction in a predetermined direction increases a display area on a screen, and
the third process of rotating the image so as to display the video in the first display direction, on the basis of determination that the display area on the screen increases in the first display direction.
