Description

  The present invention relates to a content display device and a program for displaying content on a display screen.

  In recent years, a large screen has been developed in various devices that display content such as computers and AV devices. In addition, there are known ones that display a large number of contents at once using a large-screen display device, and those that allow a plurality of users to share and use one display screen.

  When displaying many contents at once, it is necessary to be able to understand the contents of each content.

  Therefore, as a conventional technique, for example, in a content display device, when an operation to reduce the layered content is performed, a special reduction display process is performed when the display magnification exceeds a threshold value. Has been proposed to improve the visibility by displaying characters in a font size that is visible (see Patent Document 1).

  In addition, when a plurality of users share and use one display screen, it is necessary to rotate and display content or the like in a direction corresponding to a specific user among the plurality of users.

  Therefore, as an example of rotating the content displayed on the display screen as a conventional technique, for example, in an image processing apparatus, an image processing program for rotating an object with a simple operation and displaying it within a display frame is proposed. (See Patent Document 2).

  As another example, in the display control device, when dragging is performed on a display object on the display screen, the display object is controlled so as to scroll the display object following the drag, and the position where the drag is performed When the input is completed, if the last movement direction is the first direction in accordance with the last movement direction of the drag, the display object is returned to the separation position immediately before the currently displayed position. A display in which the display object is scrolled has been proposed (see Patent Document 3).

  Then, it is determined whether or not the rotation angle α ° of the content 2 is the original rotation angle 0 ° or the rotation angle 180 ° (step S205).

  When it is determined in step S205 that the rotation angle α ° of the content 2 is the original rotation angle 0 ° or the rotation angle 180 °, the content 2 is restored to the original size and coordinate position before the operation is started. Content 2 is displayed (step S206), and the size and position information of the content 2 before the operation is started are deleted (step S207).

  On the other hand, if it is determined in step S205 that the rotation angle α ° of the content 2 is not the rotation angle 0 ° or the rotation angle 180 ° of the original state, the content diagonal line L2 and the bottom side are calculated from the size before the operation of the content 2 is started. An angle β ° formed by L3 is calculated (step S208).

  In step S209, the height γ of the content 2 is calculated. In step S210, it is determined whether the height γ of the content 2 is larger than the display area of the content 2.

  In step S210, when it is determined that the height γ of the content 2 is larger than the display area of the content 2, the content frame is reduced and displayed in a reduced state. At this time, the display magnification of the image inside the content is maintained at the original display magnification at which the content 2 was displayed, and the content 2 rotated at the same size is displayed (step S211).
