Abstract
Abstract In order to produce high quality colour presentation graphics such as posters, advertisements, notices, greeting cards etc., efficiently and at a low cost, there is provided a graphics system (1) for a colour copier(24). The system (1) includes a memory card (15) input (7) for object image data, a host processor (2) connected to a user controllable keyboard (20) for selecting and editing the object image data to create edited image data, a real-time object processor (12) for rendering the edited image data to output an image signal (17) to the copier (24) for printing an image represented by the image signal. The system (1) is characterised by the absence of an image frame store.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
91 words
A graphics system (1) for a colour copier (24), said system comprising an input (7,20-22) for object image data, host processor means (2) connected to a user controllable input means (20) for selecting and editing said object image data to create edited image data, characterised in that said system (1) further comprises real-time image processing means (12) for rendering said edited image data to output an image signal , and communication means (8,25) for interconnecting said system (1) with said copier (24) for printing an image represented by said image signal.
Claim 2
Dependent Claim
73 words
A graphics system as claimed in claim 1 characterised in that said real-time image processing means (12) comprises a real time object processor means (12) for rendering said edited image data, and said system (1) further comprises a colour transformation means (8,13) connected to said real time object processor means (12) and adapted to receive said rendered edited image data (17) and to determine said image signal from said rendered edited image data.
Claim 3
Dependent Claim
23 words
A graphics system as claimed in claim 1 or 2 characterised in that said image data is based on quadratic polynomial fragments (QPF's).
Claim 4
Dependent Claim
60 words
A graphics system as claimed in claim 1, 2 or 3 characterised in that said real-time image processing means (12) also produces a video image signal (17) for driving a video presentation means (27,28) and said graphics system (1) further comprises a video presentation means (27,28) adapted to receive said video image signal (17) and display a corresponding video image.
