Method of manipulating visibility of images on a volumetric display
The invention relates to a method of manipulating the visibility of image elements on the screens of a multi-screen display. In particular, methods of maximising the visibility of selected target image elements are identified.
1. A method of manipulating apparent visibility of a target image displayed on a display comprising a first screen and a second screen, said method comprising:
identifying said target image;
determining an intended screen to display said target image, wherein said intended screen is one of said first screen and said second screen;
determining the position of said target image on said intended screen;
identifying a portion of said target image that overlaps between said intended screen and said first screen provided said intended screen is said second screen;
identifying a portion of said target image that overlaps between said intended screen and said second screen provided said intended screen is said first screen; and
manipulating said portion to change said apparent visibility of said target image displayed on said intended screen.
2. The method as described in claim 1 , wherein said manipulating comprises:
placing an image element corresponding to said identified portion of said target image; and
changing an alpha value of said placed image element.
3. The method as described in claim 2 , wherein said placed image element is placed on said intended screen.
4. The method as described in claim 2 , wherein said placed image element is placed on a screen other than said intended screen.
5. The method as described in claim 2 , wherein said placed image element is a shadow image positioned substantially behind said target image, wherein said shadow image is formed from a solid color.
6. The method as described in claim 5 , wherein said solid color is white.
7. The method as described in claim 2 , wherein said placed image element is a mask image positioned substantially in front of said target image, wherein said mask image is formed from a solid color.
8. The method as described in claim 7 , wherein said solid color is white.
9. The method as described in claim 1 , wherein said manipulating comprises:
placing an image element corresponding to said identified portion of said target image; and
changing transparency of said placed image element.
10. The method as described in claim 1 further comprising:
changing characteristics of said target image, wherein said characteristics are selected from a group consisting of alpha values, color, hue, saturation, brightness and RGB values.
11. The method as described in claim 1 further comprising:
changing characteristics of images other than said target image, wherein said characteristics are selected from a group consisting of alpha values, color, hue, saturation, brightness and RGB values.
12. The method as described in claim 11 , wherein said images other than said target image are on a screen other than said intended screen.
