Operational display device and method of controlling the same, and recording medium

A method of controlling an operational display device performed by a computer of the operational display device including a display portion for displaying an image based on image data including a specific portion, comprising:

• detecting an orientation in which said display portion is held;
• and
• rotating and displaying an image of said specific portion as being zoomed-in in accordance with an orientation of holding of said display portion when the orientation in which said display portion is held is changed from a first orientation to a second orientation,
• wherein a longitudinal direction of a display area on said display portion is changed when the orientation in which said display portion is held is changed from said first orientation to said second orientation,
• determining, by a display control unit, whether the longitudinal direction of said display area and a longitudinal direction of the image of said specific portion cross each other when said display portion is in said first orientation,
• wherein, when said display control unit determines that the longitudinal direction of said display area and the longitudinal direction of the image of said specific portion cross each other, said display control unit causes the image of said specific portion to be rotated and displayed as being zoomed-in in accordance with the orientation of holding of said display portion as the orientation in which said display portion is held is changed from the first orientation to the second orientation, and
• wherein, when said display control unit determines that the longitudinal direction of said display area and the longitudinal direction of the image of said specific portion do not cross each other, said display control unit causes the image of said specific portion to be displayed as being zoomed-in without rotating the image as the orientation in which said display portion is held is changed from the first orientation to the second orientation.

A non-transitory computer readable recording medium recording a program executable by a computer of an operational display device including a display portion for displaying an image based on image data including a specific portion, said program causing said computer to perform:

• detecting an orientation in which said display portion is held;
• and
• rotating and displaying an image of said specific portion as being zoomed-in in accordance with an orientation of holding of said display portion when the orientation in which said display portion is held is changed from a first orientation to a second orientation,
• wherein a longitudinal direction of a display area on said display portion is changed when the orientation in which said display portion is held is changed from said first orientation to said second orientation;
• determining whether the longitudinal direction of said display area and a longitudinal direction of the image of said specific portion cross each other when said display portion is in said first orientation,
• wherein, when a determination is made that the longitudinal direction of said display area and the longitudinal direction of the image of said specific portion cross each other, causing the image of said specific portion to be rotated and displayed as being zoomed-in in accordance with the orientation of holding of said display portion as the orientation in which said display portion is held is changed from the first orientation to the second orientation, and
• wherein, when a determination is made that the longitudinal direction of said display area and the longitudinal direction of the image of said specific portion do not cross each other, causing the image of said specific portion to be displayed as being zoomed-in without rotating the image as the orientation in which said display portion is held is changed from the first orientation to the second orientation.

An operational display device, comprising:

• a display portion for displaying an image based on image data including a specific portion;
• a detection portion for detecting an orientation in which said display portion is held;
• and
• a processor for controlling a manner of display on said display portion,
• said processor causing an image of said specific portion to be rotated and displayed as being zoomed-in in accordance with an orientation of holding of said display portion when the orientation in which said display portion is held is changed from a first orientation to a second orientation,
• wherein a longitudinal direction of a display area on said display portion is changed when the orientation in which said display portion is held is changed from said first orientation to said second orientation,
• said processor determines whether the longitudinal direction of said display area and a longitudinal direction of the image of said specific portion cross each other when said display portion is in said first orientation,
• when said processor determines that the longitudinal direction of said display area and the longitudinal direction of the image of said specific portion cross each other, said processor causes the image of said specific portion to be rotated and displayed as being zoomed-in in accordance with the orientation of holding of said display portion as the orientation in which said display portion is held is changed from the first orientation to the second orientation, and
• when said processor determines that the longitudinal direction of said display area and the longitudinal direction of the image of said specific portion do not cross each other, said processor causes the image of said specific portion to be displayed as being zoomed-in without rotating the image as the orientation in which said display portion is held is changed from the first orientation to the second orientation.
