Sure Digi-View can capture images up to its maximum resolution when using a
color splitter (read extra hardware expense) and an extremely stable
digital freeze frame (read not a normal consumer unit – extra hardware
expense.) Digi-View can also digitize images in Hi-Res at 4096 colors,
with noticable color banding, sometimes very severe.
I think digi-view is a good product, but I would hardly call it a high
quality image processor. It does the job economically, and far better than
similar systems on either the Amiga or other platforms, however.
OK. IF YOU HAVE 2 MEGS OF RAM, you can link to Digi-Paint 3, a stand alone
product at extra software expense. I have NEVER seen an advertisement for
AREXX, and cannot get anyone to give me an understandable description of
what it does and why it is a needed product. Perhaps you can write AREXX
programs doing all kinds of miracles, if you happen to be a programmer and
can find the product.
Some versions of digi-view may save in larger file formats. I don't know.
My version saves in 320×200 or 320×400 in HAM mode. It does have high
resolution, which does a creditable job in grays, but lacks a sufficient
number of colors to do the job with people, portraits, and nature scenes
when using high res. color. (A limitation of Amiga hardware.)
The fact remains that it is a slow scan digitizer, designed to reproduce
static images with a video camera. Good images require a stable image for
at least 30 to 60 seconds. Most video recorders cannot provide a stable
enough image for that period of time to do a creditable job.
I'd sure like to see hardware capable of displaying 16 million colors. By
my count, a normal 320×400 interlaced screen has 128 THOUSAND pixels, while
a high resolution 640×400 interlaced screen has 256 THOUSAND pixels. Even
if each pixel were addressed separately with a discrete color, there is no
way a normal Amiga screen can approach displaying 16 million colors. Even
your high resolution overscan screen has only 354,640 pixels available.
