The AFP-AT is a powerful add-on image processing card for the ISA bus.
All true color (RGB) or b/w video sources in the 625 lines/50 Hz or
525 lines/60 Hz formats may be connected.
Monochrome images are being digitized and stored with a resolution
of 8 bit, true color frames with either 3x8 bit, 3x5 bit or 2x3 bit and
1x2 bit.
Up to 12 MB of framestore capacity and up to 2 MB of graphic overlay
memory are provided by the card.
The framestore may be configured to digitize true color images with
resolutions of 768x512, 512x512, 768x256, 512x256, 384x256, or 256x256.
It is defined as one frame of up to 2048x2048x24 bit.
In addition, the card contains a 4-bit graphic overlay memory plane
in the same geometrical size as the framestore (2048x2048x4 bit). The entire
memory may be used for real-time digitization of b/w film sequences. The
AFP-AT card contains three 8-bit ADCs. Each of these ADCs' lower and upper
level (gain and offset) are programmable separately.
6 video inputs allow the connection of either 2 true color RGB cameras
or up to 6 monochrome cameras. The input channel selection is programmable
as well.
Two other inputs allow the connection and selection of 2 external sync
signals. With its built-in PLL circuit, the card automatically locks onto
the connected video source, which must be of either 625 lines/50 Hz or
525 lines/60 Hz.
The AFP-AT may be programmed as master or slave: operating in master
mode, the card will generate the sync pulses from its own cristal oscillator,
in slave mode, it will lock onto the connected video source.
Stored images can be displayed either interlaced (video norm) or non-interlaced
(twice the video speed, no flickering!). Non-interlaced operation requires
a multisync color monitor.
The AFP-AT card offers 1 output and 8 input look-up tables of 256x24
bit each. It also features a hardware zoom/pan function (factor 2).
The CPU's access to pixel data is performed via a 64-kB block at address
A0000hex or D0000hex (jumper selectable). This 64-kB block is configured
as a 256x256 window. With a built-in real-time address mapper, it may be
panned over the full frame memory. There may be selected 1 of 8 possible
mapforms (horizontal: 256x256, 512x218, 1024x64, 2048x32; vertical: 256x256,
128x512, 64x1024, 32x2048).
As this feature eliminates time consuming DMA transfer, the AFP-AT
card reaches processing cycle times of less than 1 second.
Hence, the card easily qualifies for advanced industrial applications,
like quality control and robot vision.
The overlay memory's MSB (most significant bit) can be configured as
video write mask, that determines which parts of the video frame will be
updated during the next video write cycle (partial video frame acquisition).
An 8bit wide and fast video data bus (upward compatible with LFS-AT
video bus), and a 24 bit wide video bus allow efficient data transfer to
other image processing modules.
The transfer speed of these buses amounts to 15 MHz. Thanks to a special
EGA/VGA graphic adapter input, you are free to switch your monitor display
to either graphic adapter (DOS) level or framestore level (single monitor
operation).
The AFP-AT image processing card provides 4 opto-isolated, programmable
digital inputs and 4 regular outputs to execute simple control functions
without the necessity of further hardware (e.g. "control start"
or "result ok/not ok").
A particular system that is designed to record very long image sequences
may contain up to 4 AFP-ATs.
