Appeal No. 1998-1110
Application No. 08/391,263
The invention relates to a device and method for image
compression and/or expansion using a parallel processor. A
single instruction multiple datastream (SIMD) machine such as
a Geometric Arithmetic Parallel Processor
(GAPP)(Specification, pages 8-12), having a plurality of
substantially identical cells for processing digital data
signals (Specification, page 5,
line 28) is used as a first means for parallel aggregation of
selected ones of a first plurality of picture elements into
first aggregates which each include a copy of more than one of
the picture elements (Specification, page 18, line 29 to page
19, line 5; Figure 13). The GAPP then functions as a second
means for parallel aggregation of the first aggregates into
second aggregates, each of which includes a copy of more than
one first aggregate (Specification, page 19, lines 3-8; Figure
13, note especially the transitions from Fig. 13(b) to Fig.
13(c),
Fig. 13(c) to Fig. 13(d), etc.).
Independent claim 1 is reproduced as follows:
1. A device for transforming a first representation of an
information pattern made up of a plurality of picture elements
into a second representation of the information pattern, the
