technology.
The
Silicon Imaging MegaCameraHDä
(SI-1920HD) unleashes a new generation of
high-performance HDTV CMOS camera power that not only replaces
traditional CCD cameras, but surpasses their capability in single
chip high-quality HD video applications including broadcast sports,
animation, matte work, miniatures, Stereoscopic 3D and
slow-motion special effects. HDTV 1920 x
1080 at 60FPS (SMPTE 274M 1080P Timing) By integrated a 2/3”
optical format 2.1 Megapixel HDTV CMOS imaging sensor with multi-tap
12-bit A/D conversion, digital signal processing, programmable
timing generation and high-speed cameralink digital outputs, Silicon
Imaging has developed the worlds smallest 1920 x 1080 60Hz
progressive scan (SMPTE274M timing) HD camera.
68dB Wide Dynamic Range ( > 11bits) Perhaps one of the most important characteristics of this CMOS camera
is its ability to produce high-quality images even under adverse
illumination. Unlike CCD cameras which can bloom and reduce their
dynamic range with increased data rates (generally 50~55db), the
SI-1920HD delivers excellent performance at low light levels with
>11 bits of dynamic range. The
total noise for this camera is limited to a S/N to 52dB at 0dB gain.
Increasing sensor gain to 6dB boosts the S/N to 57.5dB.
At Pixel-limited read noise of only three electrons, at a
gain of 18dB yields an S/N of 68dB and an ISO speed approaching
1600. VariScanHD™ - 16:9 & 4:3 Aspect Switching and Variable Rate The VariscanHD feature enables the camera to produce HD video in
multiple formats with applicable timing and resolution standards
including SMPTE 274M, 296M, 293M and ITU-R 601. It takes advantage of the windowing capability of CMOS
arrays to directly capture "native" 1080i, 1080p/30, and
720p, or switch between 4:3 and 16:9, while maintaining correct
clock timing for the desired format.
720P Slow-Motion, Stereoscopic 3-D &
Special Effects at 120fps In 720P mode the camera is capable of achieving selected frame rates
from: 4-fps up to 120-fps. When
acquiring for 24-fps projects, higher than 24-fps operation can be
processed for slow motion effects while slower than 24-fps operation
can be processed to speed up motion.
Combining the variable frame rate and a variable shutter
speed can create interesting ghost like motion blur effects, warp
speed zoom effects, and long exposure still shots typical of what
one might see in music videos, sci-fi dramas and dream sequences.
For high speed motion capture, the 720p mode at 120fps produces
images without blur. Using
the SI-1920HD-3D stereo pair configuration, left/right eye images
can be captured in synch to create high-definition 3-D stereoscopic
sequences. Enhanced Sensitivity with Binning &
Line Mixing For monochrome application, a constant optical format can be
maintained while enhancing sensitivity by enabling both line mixing
and pixel binning. Using
a1.5®1 binning and line-mixing, the
on-chip signal processing converts the full 2/3-inch format 1920
by 1080 to
lower resolution (1280 by 720) with enhanced sensitivity. 12-Bits
Uncompr Unlike traditional broadcast and video cameras, which colorize and
encode the image data for transmission on analog or digital (HD-SDI)
output, the MegaCameraHD™ outputs raw 12-bits/pixel at 150MHz
(1.8Gb/sec). The
image data is transmitted to a recording system using a dual-tap
(2x12-bit 75MHz) base cameralink interface and frame grabber.
The image data can then be expanded into an RGB per pixel
(4:4:4) format with interpolation and color matrix for display on PC
graphic or industry standard HD-SDI playback hardware.
As the 12-bit original data is always maintained, no detail
is lost in encoding, transcoding or recording. CameraLink Digital Interfaces GigE-Cameralink
