Embedding color profiles in raster image data using data hiding techniques
First Claim
Patent Images
1. A method comprising:
- obtaining information describing color properties of a device that generates an image; and
embedding the information within raster image data associated with the image such that the embedded information does not substantially affect the visual appearance of the image to a user.

Abstract
In one embodiment, raster image data of an image including pixel intensity, pixel color, or the like, can be varied slightly to encode color profile data within the image without significantly altering the visual appearance of the image. The encoded data may represent color profile data for a source device, and can be extracted by a destination device for use in performing color transformations for improved color image accuracy.
