Web image transfer system using LED based lighting systems
First Claim
1. A system for transmitting a color image over a network, the system comprising:
- a light source;
a first reference color means exhibiting a first spectral response;
a camera capturing an image of the first reference color means for transmission to a receiver;
a receiver for displaying the image, the displayed image exhibiting a second spectral response;
a second reference color means replicating the first spectral response;
a comparator for generating a signal responsive to a difference between the replicated first spectral response and the second spectral response; and
an adjuster for adjusting the displayed image responsive to the signal.

Abstract
A system for transmitting a color image over a network. The system has a light source, a first reference color chart exhibiting a first spectral response, a camera capturing an image of the first reference color chart for transmission to a receiver, and a receiver for displaying the image. The displayed image exhibits a second spectral response. The system also has a second reference color generator replicating the first spectral response, a comparator for generating a signal responsive to a difference between the replicated first spectral response and the second spectral response, and an adjuster for adjusting the displayed image responsive to the signal.

23. A method of adjusting illumination of a scene by a light source, the method comprising the steps of:
-
illuminating a color chart adjacent the scene, the color chart exhibiting a first spectral response with the light source;
capturing an image of the illuminated color chart;
displaying the image on a display screen, the displayed image exhibiting a second spectral response;
generating a signal responsive to a difference between the first and second spectral responses; and
adjusting the illumination of the scene by the light source responsive to the signal.
