Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
153 words
Image scanning apparatus for scanning an image to produce pixels representative of said image, with first image processing means (38) for processing at least line copy images; and second image processing means (39, 40) for processing at least one other image type characterized by: control means (32) for operating the scanning apparatus at high speed to scan said image while actuating said first image processing means to process the pixels produced on the assumption that said image comprises at least line copy; and image monitoring means (35, 36) for monitoring the content of said image while said image is being scanned at high speed to detect said other image type; said control means operating said scanning apparatus to scan said image at reduced speed in response to detection of said other image type while actuating said second image processing means to process the pixels produced by scanning said image at said reduced speed.
Claim 2
Dependent Claim
153 words
Image scanning apparatus for scanning an image to produce pixels representative of said image, with first image processing means (38) for processing at least line copy images; and second image processing means (39, 40) for processing at least one other image type characterized by: control means (32) for operating the scanning apparatus at high speed to scan said image while actuating said first image processing means to process the pixels produced on the assumption that said image comprises at least line copy; and image monitoring means (35, 36) for monitoring the content of said image while said image is being scanned at high speed to detect said other image type; said control means operating said scanning apparatus to scan said image at reduced speed in response to detection of said other image type while actuating said second image processing means to process the pixels produced by scanning said image at said reduced speed.
Claim 3
Dependent Claim
20 words
The scanning apparatus according to claim 1 characterized by: means for scanning only portions of said image at high speed.
Claim 4
Dependent Claim
39 words
The scanning apparatus according to claim 1 in which said other image type comprises halftone images, characterized by: said second image processing means comprising halftone image processing means (39) for processing halftone images detected by said image monitoring means.
Claim 5
Dependent Claim
42 words
The scanning apparatus according to claim 1 in which said other image type comprises continuous tone images, characterized by: said second image processing means comprising continuous tone image processing means (40) for processing continuous tone images detected by said image monitoring means.
Claim 6
Dependent Claim
49 words
The scanning apparatus according to claim 1 in which said other image type comprises both halftone and continuous tone images, characterised by: said second image processing means including halftone image processing means (39) for processing halftone images and continuous tone image processing means (40) for processing continuous tone images.
Claim 7
Independent Claim
81 words
A method of scanning an image bearing document to produce signals representative of the images scanned, characterised by the steps of: a) scanning said document line by line at a first relatively high speed appropriate to line copy images; b) while scanning at said first speed, monitoring the images being scanned to detect images of at least one other type, and c) when images of one of the other types are detected, scanning the document at a second relatively lower speed.
Claim 8
Independent Claim
81 words
A method of scanning an image bearing document to produce signals representative of the images scanned, characterised by the steps of: a) scanning said document line by line at a first relatively high speed appropriate to line copy images; b) while scanning at said first speed, monitoring the images being scanned to detect images of at least one other type, and c) when images of one of the other types are detected, scanning the document at a second relatively lower speed.
Claim 9
Dependent Claim
34 words
The method according to claim 6 characterised by the step of: rescanning at least the line being monitored at said second relatively low speed when one of the other types of image is detected.
