Abstract
Abstract 57 Printed images in fields on a document are scanned (10) along a plurality of scan lines producing image data for each line. A chain of sets of control instruction, each set relating to an image field, is stored. The data for each scan line is processed (17, 18, 19) by the sets of instructions in succession. When the image in a field has been completely processed the corresponding set of control instructions is deleted from the chain of sets of instructions (17).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
An image data processing system for processing image data resulting from the scanning in a series of scan lines of a document on which have been printed images in predetermined fields of said document comprising means for storing a chain of sets of control instructions, each set relating to a corresponding field of said document, means for receiving said image data as a sequence of sets of data signals, each set relating to a corresponding scan line, and processing means operable upon receipt of said sets of data signals to process said sets of data signals according to said sets of control instructions in order to produce output data, characterised in that said processing means processes each set of data according to each set of control instructions in said chain in succession.
Claim 2
Dependent Claim
132 words
An image data processing system for processing image data resulting from the scanning in a series of scan lines of a document on which have been printed images in predetermined fields of said document comprising means for storing a chain of sets of control instructions, each set relating to a corresponding field of said document, means for receiving said image data as a sequence of sets of data signals, each set relating to a corresponding scan line, and processing means operable upon receipt of said sets of data signals to process said sets of data signals according to said sets of control instructions in order to produce output data, characterised in that said processing means processes each set of data according to each set of control instructions in said chain in succession.
Claim 3
Dependent Claim
41 words
A system as claimed in claim 1 characterised in that said processing means operates to delete from said chain of sets of control instructions any set of instructions which relates to a field for which the data processing has been completed.
Claim 4
Dependent Claim
62 words
A system as claimed in claim 3 characterised in that each set of control instructions include a first pointer indicating the next set in the chain and a second pointer indicating the previous set in the chain and said processing means includes means for selectively changing the value of said pointers in order effectively to delete one or more sets of instructions.
Claim 5
Dependent Claim
64 words
A system as claimed in claim 3 in which in order to delete a selected set of instructions the processing means changes the first pointer of the previous set of instructions to the value of the second pointer in said selected set and changes the second pointer of the next set of instructions to the value of the first pointer of said selected set.
Claim 6
Independent Claim
56 words
A system, as claimed in any one of the preceding claims characterised in that each scan line is associated with a respective one of a sequence of numbers and said processing means utilises said sequence of numbers to determine which set of control instructions is to be used to process the data from each scan line.
