OVERVIEW
The VDP-7500 is part of the LSI Logic VisionSpectrumTM Display Processor (VDP)
family, which contains the best-in-class, high-performance video and display processors
suitable for Digital CRTs, LCDs, Plasmas, and Front- and Rear-Projection TVs.
VDP-7500 is designed for use in mainstream display products. VDP-7500 supports
worldwide Standard Definition and High Definition baseband inputs and performs
advanced video processing to enable the best viewing experience on any
flat-panel display.
VDP-7500 utilizes LSI Logic’s industry-leading ClearViewTM technology to provide
optimum picture quality and innovative features enabling manufacturers to differentiate
their products.
ClearView technology combines state-of-the-art proprietary Pixel Enhancement,
3D Motion Adaptive Deinterlacing with Jaggie Edge Reduction, Advanced 3D Noise
Reduction including built-in Digital 3D Comb filter for NTSC and PAL modes - all
of which work together to produce a superior picture. VDP-7500 architecture also
integrates many other display display processing functions such as up/down scaling,
PIP/POP, contrast/color enhancements and edge enhancements making it one of the most
feature-rich yet cost-effective display processing solutions available in the market today.

CLEARVIEWIMAGE PROCESSING
TECHNOLOGY
Watching noisy video or improperly scaled and deinter-
laced video can ruin the viewing experience especially on
larger displays where every artifact is magnified. LSI Logic’s
industry-leading ClearView technology provides a powerful
combination of digital 3D comb filtering for NTSC/PAL,
advanced motion-adaptive 3D deinterlacing, 3D Noise
Reduction and Pixel Enhancement to produce a visually
superior picture on almost any flat panel display.
Advanced Film Mode Recovery with Pattern Breakdown
Detection and Correction
The built-in Auto Film Mode detection ensures proper
recognition and handling of a 3:2 (NTSC) or 2:2 (PAL) pull
down sequence in TV-adapted film material during the dein-
ClearView Super3D Comb Filter
The 3D adaptive digital temporal comb filter provides
reduction of cross color and cross luma interference resulting
from combining the Y(luma) and C(Chroma) in NTSC/PAL
composite signals. Having this built-in eliminates the need for
an expensive external 3D Comb filter in many cases thereby
saving cost. It also provides significant improvement in the
quality of S-Video input signals where the orginal source
contained YC interference noise (something which external
3D Comb solutions don’t handle)
ClearView Deinterlacing
3D Motion Adaptive Video Deinterlacer
The ClearView 3D Motion Adaptive Deinterlacer uses motion
detection and sophisticated 3D Interpolation and 3D Jaggie
Edge Reduction techniques to reduce artifacts and jagged
edges during the deinterlacing process, resulting in a much
more appealing picture. It is a software-programmable
engine that easily allows fine-tuning the picture quality
based on panel characteristics.
Example of ClearViewintelligent Noise Reduction.
terlacing process. It uses pattern recognition to reconstruct the
original progressive frames rather than interpolate the missing
pixels. It also detects and corrects a breakdown in the pull-
down pattern or fields mismatched during the editing process,
which would normally result in undesirable artifacts in the
final displayed output.
ClearView Noise Reduction
3D Motion Adaptive Noise Reduction
The 3D Noise Reduction Engine reduces random noise
in the picture by using pixel-level motion detection algorithms.
This results in a much cleaner image especially in the case
of high noise still images.
ClearView Pixel Enhancement
ClearView Pixel Enhancement technology provides yet
another level of picture quality improvement. Its proprietary
text edge detection and smoothing algorithm results in clearer
character boundaries and is a key differentiating feature
for LCD/Plasma panel manufacturers. When applying the
enhancements to images, the picture becomes brilliant and
live even on lower-resolution display panels.

Deinterlacing.
