Abstract

A system for generating an overlay display comprises an overlay display, a camera and a processor connected to the overlay display and the camera. The overlay display is arranged to overlay an output on a background, the camera is arranged to detect the background, and the processor is arranged to receive a desired color for the output, determine the actual color of the background, and calculate the output color from the desired color and the actual color of the background.

First claim

1 . A system for generating an overlay display, the system comprising:
a memory; and a processor in communications with the memory, wherein the computer system is configured to perform a method comprising:
receiving an indication of a desired color for output to overlay a background;
determining a color of the background over which the desired color is to be output; and
determining an output color based on the desired color and the color of the background.

2 . The system of claim 1 , wherein the method further comprises receiving a transparency value for the overlay display and using the received transparency value in the determining the output color based on the desired color and the color of the background.

3 . The system of claim 1 , wherein the determining the output color based on the desired color and the color of the background comprises using a predefined formula to generate RGB values for the output color based on RGB values of the desired color as modified by RGB values of the color of the background.

4 . The system of claim 3 , wherein the method further comprises receiving a transparency value for the overlay display and using the received transparency value in the determining the output color based on the desired color and the color of the background.

5 . The system of claim 1 , wherein the determined output color varies at a per-pixel or per-pixel-block level according to variation in the color of the background.

6 . The system of claim 5 , wherein determining the output color based on the desired color and the color of the background comprises using a predefined formula to generate RGB values for the output color based on RGB values of the desired color as modified by RGB values of the color of the background.

7 . The system of claim 6 , wherein the method further comprises receiving a transparency value for the overlay display and using the received transparency value in the determining the output color based on the desired color and the color of the background.

8 . The system of claim 5 , wherein the method further comprises receiving a transparency value for the overlay display and using the received transparency value in the determining the output color based on the desired color and the color of the background.

9 . A method for generating an overlay display, the method comprising:
receiving an indication of a desired color for output to overlay a background; determining a color of the background over which the desired color is to be output; and determining an output color based on the desired color and the color of the background.

10 . The method of claim 9 , further comprising receiving a transparency value for the overlay display and using the received transparency value in the determining the output color based on the desired color and the color of the background.

11 . The method of claim 9 , wherein the determining the output color based on the desired color and the color of the background comprises using a predefined formula to generate RGB values for the output color based on RGB values of the desired color as modified by RGB values of the color of the background.

12 . The method of claim 11 , further comprising receiving a transparency value for the overlay display and using the received transparency value in the determining the output color based on the desired color and the color of the background.

13 . The method of claim 9 , wherein the determined output color varies at a per-pixel or per-pixel-block level according to variation in the color of the background.

14 . The method of claim 13 , wherein the determining the output color based on the desired color and the color of the background comprises using a predefined formula to generate RGB values for the output color based on RGB values of the desired color as modified by RGB values of the color of the background.

15 . The method of claim 14 , further comprising receiving a transparency value for the overlay display and using the received transparency value in the determining the output color based on the desired color and the color of the background.

16 . The method of claim 13 , further comprising receiving a transparency value for the overlay display and using the received transparency value in the determining the output color based on the desired color and the color of the background.

17 . A computer program product for generating an overlay display, the computer program product comprising:
a computer readable storage medium readable by a processor and storing instructions for execution by the processor for performing a method comprising:
receiving an indication of a desired color for output to overlay a background;
determining a color of the background over which the desired color is to be output; and
determining an output color based on the desired color and the color of the background.

18 . The computer program product of claim 17 , wherein the determined output color varies at a per-pixel or per-pixel-block level according to variation in the color of the background.

19 . The computer program product of claim 17 , wherein the determining the output color based on the desired color and the color of the background comprises using a predefined formula to generate RGB values for the output color based on RGB values of the desired color as modified by RGB values of the color of the background.

20 . The computer program product of claim 17 , wherein the method further comprises receiving a transparency value for the overlay display and using the received transparency value in the determining the output color based on the desired color and the color of the background.
