Abstract
Abstract The system comprises a memory formed of several disk stores for storing data representing at least one image and a working framestore for temporarily storing one or two frames of image data. Data in the framestore is modified by a processor under operator control. Data is stored in the disk stores by switching selected pixels from each line and selected lines from the or each frame, by way of switches and buffers, to respective disk stores such that the image data is divided into groups which each define a lower resolution version of the whole image frame.

Claim 1
Independent Claim
154 words
An image processing apparatus comprising: a memory for storing digital data representing at least one entire image frame, the memory comprising a plurality of storage units each for storing a data group defining a respective interleavable reduced resolution representation of substantially the entire image frame; a manipulation frame store for storing during processing data representing substantially the entire image frame; an interface for controlling data transfer between the memory and the manipulation frame store, the interface dividing the image frame data into said data groups when the data is transferred to the memory and interleaving groups of data from the storage units when the data is transferred from the memory; a processor for processing data in the manipulation frame store to create manipulated data representing a manipulated version of substantially the entire image frame; and a display store connected to receive from the processor data representing said manipulated version of the image for display.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
17 words
An image processing apparatus as claimed in claim 1, wherein the interface is controlled by the processor.
Claim 4
Dependent Claim
48 words
An image processing apparatus as claimed in claim 2, wherein the processor is operable in a preview mode in which the interface is controlled to transfer selected data groups representing substantially the entire image frame at an intermediate resolution from the storage units to the manipulation frame store.
Claim 5
Dependent Claim
30 words
An image processing apparatus as claimed in claim 3, further comprising a monitor connected to the display store for displaying at said intermediate resolution the manipulated version of the image.
Claim 6
Dependent Claim

Dependent Claim
75 words
An image processing apparatus as claimed in claim 1, wherein the interface is arranged to divide the image frame into an odd field and an even field respectively comprising odd and even numbered lines and to control the transfer data to the memory such that data corresponding to the even field contributes to one half of the data groups and data corresponding to the odd field contributes to the other half of the data groups.
Claim 8
Dependent Claim
49 words
An image processing apparatus as claimed in claim 6, wherein each line comprises a multiplicity of picture elements, and the interface is arranged to control said transfer of data to the memory such that even and odd numbered picture elements in each line contribute to respective different data groups.
Claim 9
Dependent Claim
36 words
An image processing system as claimed in claim 7, wherein the interface is arranged to control said transfer of data to the memory such that alternate even numbered picture elements contribute to respective different data groups.
Claim 10
Dependent Claim
