Description
The IPP3000R is an configuration EPROM device used with an
Altera EPF10K10 integrated circuit, provides extensive
processing capabilities for use as a basic building block
for new generation video based security systems. It is a
video motion detector operating in real time and capable of
discriminating degrees of motion as a basis for providing
enhanced image motion detection. The IPP3000R uses a
patented principle of locating edges in
both
the horizontal and vertical directions. The edges are
uniquely processed to provide substantially improved
results which minimizes false alarm conditions, while
maximizing system sensitivity insuring positive detection.
The image viewing area is subdivided into very small units
(cells). The horizontal and vertical edge processed
results are encoded into a single bit representing the
boundary status of each cell. This approach provides a
greatly reduced volume of data (128 times reduction) which
represents the status of many pieces of the image. This
condensed data format provides faster processing speed, as
well as a significant reduction of support electronics. A
typical application requires digitized image data, one
IPP3000R, one EPF10K10 (up to eight multiplexed camera
inputs) and two external RAM ICs, (MASK RAM optional). The
EPF10K10 stores a status representation of the reference
image in external RAM. It then compares the real time
representation of the image with the stored reference image
and determines the degree of change. If the change exceeds
a user selected tolerance for motion, an alarm output flag
is set. This flag sets/resets each field of the image. An
update of the reference image can be directed by an
external timer or manual/computer-controlled directive.
There are two user determined modes of external timer
motion detection available. One selects change of the real
time image from the reference image. The other detects
only the new edge conditions (intruder boundary). The
masking option allows the user to ignore specific areas of
view. The EPF10K10 can support up to eight multiplexed
camera inputs, using RS170 cameras and a video digitizer,
with a 7.5 image sample/second rate for each.
