Abstract
A stereoscopic image display apparatus for displaying a stereoscopic image, which is obtained by alternately arranging stripe parallax images R and L corresponding to the right and left eyes, in a window includes a parallax barrier for a stereoscopic vision. When the display position of a window including a stereoscopic image which is set after the window is opened or moved and the positions of the right-eye and left-eye stripes of a parallax barrier have a relationship which does not allow a proper stereoscopic vision, the display position of the window is moved by one stripe in the horizontal direction.
Claims26
An image display system capable of performing stereoscopic display, comprising:
- stereoscopic image display means for displaying a stereoscopic image having stripe parallax images arranged for right and left eyes, wherein the stripe parallax images arranged for the right eye are displayed on first stripe areas of first display means and the stripe parallax images arranged for the left eye are displayed on second stripe areas of said first display means;
- window setting means for setting a single window on a desired position of said first display means, in which a stereoscopic image comprised of stripe parallax images arranged for the right and left eyes is displayed;
- stereoscopic vision control means for displaying a parallax barrier pattern on second display means such that stripe parallax images of the stereoscopic image displayed on the first and second stripe areas of said first display means are respectively observed with the right and left eyes;
- and
- changing means for, when the stripe parallax images arranged for the right and left eyes to be displayed in the single window are displayed on the second and first stripe areas respectively, changing the display position of the single window so as to display, on the first and second stripe areas in the single window respectively, the stripe parallax images arranged for the right and left eyes without change of the parallax barrier pattern.
A method of controlling an information display system having stereoscopic image display means for displaying a stereoscopic image obtained by arranging stripe parallax images corresponding to the right and left eyes of an observer, wherein the stripe parallax images arranged for the right eye are displayed on first stripe areas of a first display and the stripe parallax images arranged for the left eye are displayed on second stripe areas of the first display, and stereoscopic vision control means for displaying a parallax barrier pattern on a second display to allow the observer to observe stripe parallax images of the stereoscopic image displayed on the first and second stripe areas of the first display with right and left eyes, respectively, comprising the steps of:
- setting a single window on a desired position of the first display of a stereoscopic image display, in which a stereoscopic image comprised of stripe parallax images arranged for the right and left eyes is displayed;
- and
- when the stripe parallax images arranged for the right and left eyes to be displayed in the single window are displayed on the second and first stripe areas respectively, changing the display position of the single window so as to display, on the first and second stripe areas respectively, the stripe parallax images arranged for the right and left eyes without change of the parallax barrier pattern.
A storage medium storing a computer program for performing image display by using an image display apparatus having a first display, a second display and stereoscopic vision control means, the stereoscopic vision control means displays a parallax barrier pattern on said second display to allow an observer to observe stripe parallax images of a stereoscopic image with right and left eyes, displayed on first and second areas of the first display respectively, said computer program comprising:
- a code for generating image data including a single window to be located on a desired position of the first display of the image display apparatus, in which stripe parallax images corresponding to the right and left eyes are arranged to display a stereoscopic image;
- a code for determining whether a relative positional relationship between the generated stereoscopic image displayed in the single window and the parallax barrier pattern displayed by the stereoscopic vision control means of the image display apparatus is a proper positional relationship which allows a proper stereoscopic vision by checking whether the stripe parallax images arranged for the right and left eyes are displayed on the first and second areas of the first display respectively;
- and
- a code for adjusting, when the single window is displayed on the first display and it is determined that the positional relationship is not proper, the relative positional relationship to allow a proper stereoscopic vision by shifting the stripe parallax images so that the stripe parallax images arranged for the right and left eyes are displayed in the first and second areas, respectively, without change of the parallax barrier pattern.
An image display system capable of performing stereoscopic display, comprising:
- stereoscopic image display means for displaying a stereoscopic image having stripe parallax images arranged for right and left eyes on first display means, wherein the stripe parallax images arranged for a right eye are displayed on a first stripe area of said first display means and the stripe parallax images arranged for a left eye are displayed on second stripe area of said first display means;
- stereoscopic vision control means for displaying a parallax barrier pattern on a second display means such that stripe parallax images of the stereoscopic image displayed on the first and second areas of said first display means are respectively observed with the right and left eyes;
- instruction means for instructing to display a new stereoscopic image on a desired position of said first display means;
- and
- display control means for displaying the new stereoscopic image on said first display means so that an observer can obtain a proper stereoscopic vision of the new stereoscopic image, with said display control means comprising:
- determination means for determining whether a relative positional relationship between the stereoscopic image displayed in a single window generated by generating means and the parallax barrier pattern displayed by said stereoscopic vision control means is a proper positional relationship which allows a proper stereoscopic vision by checking whether the stripe parallax images arranged for the right and left eyes are displayed on the first and second areas of said first display means respectively;
