Abstract
Abstract Digitized images are associated with English language captions and other data, collectively known as the metadata associated with the images. A natural language processing database removes ambiguities from the metadata, and the images and the metadata are stored in databases. A user formulates a search query, and natural language processing is used to determine matches between the query and the stored metadata. Images corresponding to the matches are then viewed, and desired images are selected for licensing. The license terms for selected images are displayed, and a subset of the selected images are ordered as desired by the user.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
90 words
A computer-implemented process of protecting an electronically stored image from unauthorized use in a first color space, comprising: storing the image in a second color space; altering a constituent second color space component of the stored image responsive to relative magnitude of said component to form an altered image by making a first alteration to first image portions having characteristics above a threshold and by making a second alteration to second image portions having characteristics below the threshold; and distributing the altered image for use in the second color space.
Claim 2
Dependent Claim
90 words
A computer-implemented process of protecting an electronically stored image from unauthorized use in a first color space, comprising: storing the image in a second color space; altering a constituent second color space component of the stored image responsive to relative magnitude of said component to form an altered image by making a first alteration to first image portions having characteristics above a threshold and by making a second alteration to second image portions having characteristics below the threshold; and distributing the altered image for use in the second color space.
Claim 3
Dependent Claim
25 words
A computer-implemented process as in claim 1, wherein the first alteration includes addition of an offset, and the second alteration includes subtraction of the offset.
Claim 4
Dependent Claim
18 words
A computer-implemented process as in claim 1, wherein the threshold corresponds to brightness of a predetermined color component.
Claim 5
Dependent Claim
14 words
A computer-implemented process as in claim 3, wherein the predetermined color component is blue.
