Abstract
Abstract A digital image processing system comprises a processor (8) at a central, first site; and digital image processing equipment such as an analyse scanner (1) and an expose scanner (2) at a second site remote from the first site. The processor (8) and the digital image processing equipment (1,2) are connectable and are adapted to pass signals therebetween corresponding to signals generated by the digital image processing equipment. These signals may be representative of operator commands or digital data generated at the second site which can be monitored at the first site.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
56 words
A digital image processing system comprising processing means (8) at a first site; and digital image processing equipment (1,2) at a second site remote from the first site, the processing means and the digital image processing equipment being connectable and being adapted to pass signals therebetween corresponding to signals generated by the digital image processing equipment.
Claim 2
Dependent Claim
56 words
A digital image processing system comprising processing means (8) at a first site; and digital image processing equipment (1,2) at a second site remote from the first site, the processing means and the digital image processing equipment being connectable and being adapted to pass signals therebetween corresponding to signals generated by the digital image processing equipment.
Claim 3
Dependent Claim
27 words
A system according to claim 1, wherein the processing means (8) and the digital image processing equipment (1,2) are adapted to pass signals in both directions therebetween.
Claim 4
Dependent Claim
27 words
A system according to claim 1 or claim 2, further comprising storage means (21) for storing a history of the operator commands generated at the second site.
Claim 5
Dependent Claim
17 words
A system according to claim 3, wherein the storage means (21) is sited at the second site.
Claim 6
Independent Claim
43 words
A system according to any of the preceding claims, wherein the digital image processing equipment (1,2) includes a monitoring system including a processor (39) responsive to a programme stored within the monitoring system, the processing means being adapted to modify the stored programme.
Claim 7
Independent Claim
72 words
A method of monitoring at a first site digital image processing equipment (1,2) at a second site remote from the first site, the digital image processing equipment being responsive to operator commands at the second site to generate digital image data, the method comprising storing a history of operator commands and/or digital data generated by the digital image processing equipment; and displaying all or part of the history at the first site.
Claim 8
Independent Claim
72 words
A method of monitoring at a first site digital image processing equipment (1,2) at a second site remote from the first site, the digital image processing equipment being responsive to operator commands at the second site to generate digital image data, the method comprising storing a history of operator commands and/or digital data generated by the digital image processing equipment; and displaying all or part of the history at the first site.
Claim 9
Dependent Claim
41 words
A method according to claim 6, wherein the step of storing a history of the operator commands and/or digital data is carried out at the second site, the history being transmitted to the first site in response to a suitable command.
Claim 10
Dependent Claim
22 words
A method according to claim 6 or claim 7, wherein only a recent history of operator commands and/or digital data is stored.
Claim 11
Independent Claim
66 words
A method of monitoring at a first site digital image processing equipment at a second site remote from the first site, the method comprising transmitting to the first site a signal representative of one or more of the operator commands and data generated by the equipment as the commands or data is generated at the second site; and monitoring at the first site the transmitted signals.
Claim 12
Independent Claim
66 words
A method of monitoring at a first site digital image processing equipment at a second site remote from the first site, the method comprising transmitting to the first site a signal representative of one or more of the operator commands and data generated by the equipment as the commands or data is generated at the second site; and monitoring at the first site the transmitted signals.
Claim 13
Independent Claim
77 words
A method of monitoring at a first site digital image input scanning equipment at a second site remote from the first site, the method comprising causing the input scanning equipment to scan a line of an image whose pixel content is already known to generate scanned digital data; transmitting information related to the scanned digital data to the first site; and comparing the transmitted information with expected information to monitor for any errors in the scanned line.
Claim 14
Independent Claim
77 words
A method of monitoring at a first site digital image input scanning equipment at a second site remote from the first site, the method comprising causing the input scanning equipment to scan a line of an image whose pixel content is already known to generate scanned digital data; transmitting information related to the scanned digital data to the first site; and comparing the transmitted information with expected information to monitor for any errors in the scanned line.
Claim 15
Dependent Claim
41 words
A method according to claim 10, further comprising comparing, at the second site, the scanned digital data with one or more thresholds and transmitting to the first site only information relating to excursions of the data outside the or each threshold.
Claim 16
Dependent Claim
29 words
A method according to claim 10 or claim 11, wherein the known image line is repeatedly scanned so that random deviations in the scanned pixel content can be eliminated.
