Composition of a Digital Image for Display on a Transparent Screen
First Claim
1. A method of preparing a digital image for display on a substantially transparent screen, the method implemented by an image processor and comprising:
- receiving environmental background data relating to an environmental background which is visible, at least in part, to a user through the screen;
dynamically calculating, based on the environmental background data, which part of the environmental background is visible to the user through the screen and thereby serves as an effective background of the screen;
composing the digital image for perceptibility as viewed against the effective background; and
outputting the composed digital image as digital data for display on the screen.

Abstract
Teachings herein prepare a digital image for display on a substantially transparent screen. The teachings advantageously recognize that the perceptibility of the digital image on the screen will often depend on what is visible to a user through the screen, since that will effectively serve as the background of the screen. A method of preparing a digital image thus includes dynamically calculating which part of an environmental background is visible to a user through the screen and thereby serves as an effective background of the screen. This calculation may entail obtaining an image of the environmental background and identifying which part of that image serves as the effective background (e.g., based on the angle at which the user views the screen). The method further includes composing the digital image for perceptibility as viewed against that effective background and outputting the composed image as digital data for display on the screen.

12. An image processor configured to prepare a digital image for display on a substantially transparent screen, the image processor comprising:
-
a communications interface configured to receive environmental background data relating to an environmental background which is visible, at least in part, to a user through the screen; an effective background calculator configured to dynamically calculate, based on the environmental background data, which part of the environmental background is visible to the user through the screen and thereby serves as an effective background of the screen; and an image composer configured to compose the digital image for perceptibility as viewed against the effective background and to output the composed digital image as digital data for display on the screen. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
