Abstract
Abstract A reprographic device having means for eliminating undesired spacings between lines of text in copies of a source medium. Such means will often have the desired effect of reducing the number of pages in a multi-page document. The present invention accomplishes this by scanning the multiple pages to create bit-mapped images, segmenting the images to identify lines of text and graphics, identifying a distance X between segments, identifying a segment spacing factor which will cause reduction in the spacing between lines of text, laying out the segments in a print page memory so that the segments are separated by a distance based on the distance X and the segment spacing factor and printing out the contents of the page memory.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
205 words
A reprographic device comprising: input means for permitting a user to specify a segment spacing decrement factor, said segment spacing decrement factor indicating a user specified spacing between segments on a copy of a medium; a scanner element for converting the contents of a medium to a bit-mapped representation; print page storage means for storing a combined bit mapped representation; a printer element for printing said combined bit-mapped representation; and an image processor for combining one or more bit-mapped representations of a medium to create said combined bit-mapped representation, said image processor comprising: receiving means for receiving a first bit mapped representation of a medium and a second bit-mapped representation of a medium; segmentation means for segmenting said first bit mapped representation of a medium and said second bit mapped representation of a medium into a plurality of segments; measuring means for identifying a distance X between a pair of adjacent segments; and layout means for laying out adjacent segments of said first bit mapped representation of a medium and said second bit mapped representation of a medium separated by a distance based on said segment spacing decrement factor and said distance X in said print page storage means to create said combined bit-mapped presentation.
Claim 2
Dependent Claim
205 words
A reprographic device comprising: input means for permitting a user to specify a segment spacing decrement factor, said segment spacing decrement factor indicating a user specified spacing between segments on a copy of a medium; a scanner element for converting the contents of a medium to a bit-mapped representation; print page storage means for storing a combined bit mapped representation; a printer element for printing said combined bit-mapped representation; and an image processor for combining one or more bit-mapped representations of a medium to create said combined bit-mapped representation, said image processor comprising: receiving means for receiving a first bit mapped representation of a medium and a second bit-mapped representation of a medium; segmentation means for segmenting said first bit mapped representation of a medium and said second bit mapped representation of a medium into a plurality of segments; measuring means for identifying a distance X between a pair of adjacent segments; and layout means for laying out adjacent segments of said first bit mapped representation of a medium and said second bit mapped representation of a medium separated by a distance based on said segment spacing decrement factor and said distance X in said print page storage means to create said combined bit-mapped presentation.
Claim 3
Dependent Claim
68 words
The reprographic device as recited in claim 1 wherein said layout means is further comprised of means for placing a first page indicator at a suitable location in said combined bit mapped representation to identify said first bit mapped representation of a medium and a second page indicator at a suitable location in said combined bit mapped representation to identify said second bit mapped representation of a medium.
Claim 4
Dependent Claim
22 words
The reprographic device as recited in claim 1 wherein each of said plurality of segments is comprised of a line of text.
Claim 5
Dependent Claim
23 words
The reprographic device as recited in claim 1 wherein said plurality of segments is comprised of line of text segments and non-text segments.
Claim 6
Dependent Claim
25 words
The reprographic device as recited in claim 4 wherein said measuring means measures a distance X between a pair of adjacent line of text segments.
Claim 7
Dependent Claim
26 words
The reprographic device as recited in claim 1 wherein said input means is a labeled switch accessible to a user and embedded on said reprographic device.
Claim 8
Dependent Claim
29 words
The reprographic device as recited in claim 1 wherein said image processor is further comprised of means for identifying a bit mapped representation of a medium as a form.
Claim 9
Dependent Claim
20 words

Claim 10
Dependent Claim
184 words
On a reprographic device, a method for reducing the number of pages need to reproduce a multi-page document, said multi-page document having text therein which is at least double spaced, said method comprising the steps of: a) scanning a first page and a second page of said document to create a bit-mapped image representation of said first page and a bit-mapped image representation of said second page; b) storing said bit mapped image representation of said first page and said bit mapped image representation of said second page in a temporary storage; c) segmenting said bit-mapped image representation of said first page and said bit-mapped image representation of said second page into a plurality of segments; d) storing a segment identifier for each segment, said segment identifier identifying spatial coordinates for a bounding rectangle for said segment in said temporary storage; e) generating a spacing factor; f) laying out each of said plurality of segments in a print page memory according to said spacing factor to create a combined image representation; and g) printing said combined image representation stored in said print page memory.
Claim 11
Dependent Claim
184 words
On a reprographic device, a method for reducing the number of pages need to reproduce a multi-page document, said multi-page document having text therein which is at least double spaced, said method comprising the steps of: a) scanning a first page and a second page of said document to create a bit-mapped image representation of said first page and a bit-mapped image representation of said second page; b) storing said bit mapped image representation of said first page and said bit mapped image representation of said second page in a temporary storage; c) segmenting said bit-mapped image representation of said first page and said bit-mapped image representation of said second page into a plurality of segments; d) storing a segment identifier for each segment, said segment identifier identifying spatial coordinates for a bounding rectangle for said segment in said temporary storage; e) generating a spacing factor; f) laying out each of said plurality of segments in a print page memory according to said spacing factor to create a combined image representation; and g) printing said combined image representation stored in said print page memory.
Claim 12
Dependent Claim

Claim 13
Dependent Claim
127 words
The method as recited in claim 10 wherein said step of laying out each of said plurality of segments in said print page memory is further comprised of the steps of: f1) retrieving said segment identifier for a first segment; f2) retrieving said first segment from said temporary storage based on said segment identifier for said first segment; f3) placing said first segment at a base location in said print page memory; f4) retrieving said segment identifier for a second segment; f5) retrieving said second segment based on said segment identifier for said second segment; f6) determining an address location for said second segment based on the address for said first segment and said spacing factor; and f7) placing said second segment at said determined address location.
