The BFP-AT is a powerful image processing card, realized as small add-on
card (half size) for the ISA bus. It is yet another result of our continuous
development of the original AFP-AT card. Both cards are, to a great extent,
software and hardware compatible.
All CCIR 625 lines/50 Hz or RS170 525 lines/60 Hz standard monochrome video
sources may be connected to the BFP-AT card. Input camera images are digitized
and stored at a resolution of 8 bit.
There are up to 2 MB of framestore and up to 1 MB of graphic overlay memory
available on board. The framestore is configured as one frame of up to
2048x1024x8 bit. It may be configured to digitize images with a resolution
of either 768x576, 768x512, 512x 512, 768x256, 512x256, 384x256 or 256x256
bit. There further exists the possibility to position images of any format
at any place of the framestore.
In addition, the BFP-AT card offers a 4-bit graphic overlay memory plane
with the same configuration as the framestore (up to 2048x1024x4 bit),
that may serve for text and/or graphic overlay, without affecting the data
in the framestore.
The card also contains an 8-bit ADC, whose lower and upper limit (similar
to gain and offset) are programmable separately.
The 4:1 video multiplexer allows the connection of up to 4 monochrome cameras.
The input channel selection is programmable as well. Synchronization of
the card to the camera is performed by a built-in PLL circuit. You may
therefore program your software to synchronize the card to the connected
b/w video source (CCIR 625 lines/50 Hz or RS170 525 lines/60 Hz), the internal
oscillator or to a connected CCD camera.
To connect several cameras, the card can be programmed as master or slave:
in master mode, the card will generate the sync pulses from its own cristal
oscillator; in slave mode, it will lock itself onto the connected video
source (CCIR or RS170).
Stored images may be displayed either interlaced (video norm), or non-interlaced
(twice the video speed, no flickering, for both 50-Hz and 60-Hz sources).
Non-interlaced operation requires a multisync color monitor.
The BFP-AT card contains an input look-up table of 256x8 bit and an output
look-up table of 256x24 bit, which offer a big variety of real-time image
manipulations.
Hardware zoom (x 2) and hardware scroll/pan functions are yet another feature.
The hardware scroll/pan does apply not only to the present window but to
the entire, disposable framestore.
The CPU will acceed pixel data via a 64-kB memory block at address D0000HEX
or E0000HEX (jumper selectable). This 64-kB block (CPU window) may be configured
in 7 different sizes: linewise 256x256, 512x128, 1024x64 and 2048x32, or
columnwise 256x256, 128x512 and 64x1024.
With a built-in real-time address mapper, the 64-kB window, in its pre-selected
size, may be panned over the full frame memory.
Depending on the calculator, memory access may occur with 1 waitstate.
In "protected mode", the entire BFP-AT/20 framestore may also
be linearly mapped at C00000HEX or E00000HEX.
The overlay memory's most significant bit (MSB) can be configured as video
write mask. This mask determines the parts of the video frame to be updated
during the next video write cycle (partial video frame acquisition or video
write mask).
An 8-bit wide, programmable video data bus allows efficient data transfer
(14.187 MB/s at 14.187 MHz) to other image processing modules.
With a built-in, programmable bypass function, you may select BFP-AT image
data or DOS information (CGA/MDA/EGA/VGA) to be displayed on the video
monitor (single monitor operation).
4 programmable, digital optocoupler inputs and 4 outputs are used to communicate,
with external hardware (e.g."control start" or "ok/not ok"
result).
With its average processing time of less than 1 second, this card easily
qualifies for many industrial applications like quality control and robot
vision.
Other applications are: medical imaging, scientific research or desk-top
publishing.
