Description
The IPP4000R is an configuration EPROM device used with an
Altera EPF10K10 integrated circuit, which supports image
processing and motion detection. It is ideally suited to
video camera based operation because it can substantially
reduce the band width of data transmitted from the camera.
It translates a digitized video image into an encoded set
of tangent line segments with inherent image noise
filtering and image enhancement. It can also develop
encoded texture data. These encoded data are in
substantially condensed form and are intended as input data
to a computer. The form of the encoded data tangent line
segments is ideally suited for linkage and evaluation by
the computer. The IPP4000 can be externally controlled to
change a differential threshold level, a motion alarm
tolerance level, and the mode (boundary vs. texture); these
can be changed asychronously with synchronized changes
occurring the next frame. Motion data are characterized in
a very condensed form while providing a great degree of
discrimination. The IPP4000 processes digitized video
camera data in real time with minimal data storage to RAM.
It supports a maximum image horizontal line size of 1024
pixels while self-adjusting to any shorter line. There are
no size limitations in the vertical direction (for
non-motion detection applications) permitting it to be used
for both linear-array and two dimension video cameras. The
maximum vertical size for motion detection is 1024 lines
per field (2048 lines per frame far interlaced cameras).
Multiple EPF10K10 devices can be cascaded and/or used for
dual (or more) differential threshold processing with
internally integrated handshake lines. Image resolution is
supported by a 40MHz (preliminary) pixel clock rate. Image
processing and motion detection are processed concurrently.
A high resolution mask is supported which permits masking
