image in just a few seconds. No special hard- ware
or extra memory is required. The other important
aspect of IVUE technology is that Live Picture can
work directly on JPEG compressed images. It
doesn't have to decompress the entire image
before using it. Only the necessary pixels are
decompressed. This greatly facilitates the use of
IVUE over networks, telecommunication lines, and
on CD ROMS.
In Live Picture, everything is accomplished with
brushes, not just painting, but image insertion,
ghosting, distortion, colour changes, blur, sharpen,
etc. The brush size is also unlimited. For example,
you can sharpen a 500MB image with a single brush
stroke, and the brush operates in real time, i.e. its
speed is independent of the underlying file size.
Live Picture also has semi-automatic silhouetting.
It takes the previous background colour and, when
the object is silhouetted, automatically calculates
the difference between the previous and new
backgrounds, and sets the edge using advanced
'Chrominance
Compensation'
that
virtually
eliminates fringing and other selection artifacts.
This significantly facilitates resolution independent
image compositing without the typical 'cut out'
look of pixel editing applications.
A beta version of Live Picture was available for
early adopters in late 1993 and the first
commercial version 1.5 shipped in July 1994 at a
cost of US$3,500. In January 1996 Live Picture
released version 2.5 for the Apple Mac Power PC
platform. Its ability to handle high resolution files
of unlimited layers in near real time and 16 bits
per channel (65,536 levels) resolution combined
with a tool set that allowed the independent
adjustment of hue, saturation, contrast and
tonality in its native HSV colour space made it a
compelling replacement for the controls offered by
