Adjustment of color in displayed images based on identification of ambient light sources
First Claim
Patent Images
1. A method of adjusting color of images displayed in ambient light, comprising:
- sensing a signal from a plurality of spectral regions of an ambient light source to define a sensed signature of the ambient light source;
comparing the sensed signature to predetermined signatures of candidate light sources to identify a candidate light source that corresponds to the ambient light source; and
creating images modified by a predefined color adjustment for the candidate light source identified.

Abstract
A method for adjusting color of images displayed in ambient light. A signal may be sensed from a plurality of spectral regions of an ambient light source to define a sensed signature of the ambient light source. The sensed signature may be compared to predetermined signatures of candidate light sources to identify a candidate light source that corresponds to the ambient light source. Images may be created so that the images are modified by a predefined color adjustment for the candidate light source identified.

14. A system for adjusting color of images displayed in ambient light, comprising:
-
a light engine configured to create images from a set of image representations;
a light sensor for sensing a signal from each of a plurality of spectral regions of an ambient light source to define a sensed signature of the ambient light source; and
a controller in communication with the light sensor and the light engine, the controller having access to a predetermined signature and a predefined color adjustment for each of a plurality of candidate light sources, the controller being configured to compare the sensed signature to the predetermined signatures to identify a candidate light source that corresponds to the ambient light source, thereby defining a selected color adjustment based on the candidate light source identified, the controller also being configured to modify each of the images created by the light engine with the color adjustment for the candidate light source identified. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A program storage device readable by a processor, tangibly embodying a program of instructions executable by the processor to perform methods steps for adjusting color of images displayed in ambient light, the method steps comprising:
-
providing a predetermined spectral signature and a predefined color adjustment for each of a plurality of candidate light sources;
sensing a signal from a plurality of spectral regions of an ambient light source to define a sensed signature of the ambient light source;
comparing the sensed signature to each predetermined signature to identify a candidate light source that corresponds to the ambient light source, thereby selecting a color adjustment based on the candidate light source identified; and
creating images modified by the selected color adjustment. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
