Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
89 words
A method for analyzing the data corresponding to a working image displayed on an electronic visual display device comprising: a) first acquiring a working image from a working image file; b) second acquiring a reference image from a reference image file; c) third comparing the working image with the reference image; d) fourth identifying areas of interest; and e) fifth acquiring text from a reference text file after the working image and the reference image have been acquired, displayed, and compared and displaying the text regarding areas of interest.
Claim 2
Independent Claim
89 words
A method for analyzing the data corresponding to a working image displayed on an electronic visual display device comprising: a) first acquiring a working image from a working image file; b) second acquiring a reference image from a reference image file; c) third comparing the working image with the reference image; d) fourth identifying areas of interest; and e) fifth acquiring text from a reference text file after the working image and the reference image have been acquired, displayed, and compared and displaying the text regarding areas of interest.
Claim 3
Dependent Claim
24 words
The method of claim 1, including the step of displaying the working image after acquiring the working image data from the working image file.
Claim 4
Dependent Claim
24 words
The method of claim 1, including the step of displaying the reference image after acquiring the reference image data from the first data bank.
Claim 5
Dependent Claim
21 words
The method of claim 3, wherein said reference image is displayed on the same screen as a previously displayed working image.
Claim 6
Dependent Claim
25 words
The method of claim 1, including the step of scrolling through a series of reference images to find the closest match with the working image.
Claim 7
Dependent Claim
19 words
The method of claim 1, including the step of obtaining correspondence of the working image and the reference image.
Claim 8
Dependent Claim
45 words
The method of claim 6, including the steps of: selecting the same feature in the working image and the reference image; and positioning that feature in the same location within the field o( the working image and the field of the reference to obtain correspondence.
Claim 9
Dependent Claim
18 words
The method of claim 1, including the step of outlining the areas of interest in the working image.
Claim 10
Dependent Claim

The method of claim 1, including the step of indentifying a point of interest within the area of interest.
Claim 13
Dependent Claim
18 words
The method of claim 11, including the step of displaying the reference text for the point of interest.
Claim 14
Independent Claim
144 words
A system for analyzing the data corresponding to a working image to be displayed on an electronic visual display device providing textbook information regarding particular areas of interest within the working image, comprising: a working image file, having at least one working image; a reference image file, having at least one reference image that corresponds to at least one working image in the working image file; means for identifying a particular area within said reference image of said reference image file which corresponds to a particular area of interest identified within said working image of said working image file; a means for accessing reference text after identification of the particular area of interest in said reference image, having reference text corresponding to said particular area of interest in said working image; and means for displaying the reference text corresponding to the area of interest.
Claim 15
Independent Claim
144 words
A system for analyzing the data corresponding to a working image to be displayed on an electronic visual display device providing textbook information regarding particular areas of interest within the working image, comprising: a working image file, having at least one working image; a reference image file, having at least one reference image that corresponds to at least one working image in the working image file; means for identifying a particular area within said reference image of said reference image file which corresponds to a particular area of interest identified within said working image of said working image file; a means for accessing reference text after identification of the particular area of interest in said reference image, having reference text corresponding to said particular area of interest in said working image; and means for displaying the reference text corresponding to the area of interest.
Claim 16
Dependent Claim
30 words
The system of claim 13, wherein said means for identifying areas of interest is an image merger that places the reference image onto the same screen as the working image.
Claim 17
Dependent Claim
38 words
The system of claim 13, wherein said means for displaying text includes text enabler that accesses the reference text file and a image/text corresponder, said image/text corresponder providing the corresponding text to each point in the reference image.
Claim 18
Dependent Claim
34 words
The system of claim 15, wherein said means for displaying includes an image merger that places the reference image, the reference text, and the working image onto the same screen as the working image.
Claim 19
