INTRODUCTION
Silicon Imaging
is proud to continue its innovation in high-resolution
color vision camera. Driven by the growing demand for consumer Digital
Still Cameras, CMOS sensors are continuing to break technical barriers
and surpass the performance characteristics of CCD’s in many photonic,
imaging and consumer applications. By utilizing a single highly integrated
CMOS device, which incorporates Megapixel sensing areas, timing
generation, Analog-to-digital Conversion and signal processing, Silicon
Imaging has developed a very compact, low-power, ultra high speed
Megapixel digital camera system.
2048 x 1536 Megapixel - Ultra Resolution
The SI-3300 is an all-digital ½” format CMOS camera that delivers 3.2
Million pixels of resolution and is capable of running at over 12
frames/second at its full 2048 x 1536 resolution. The entire package is
only 45 x 52 x 50mm (33 x 40mm x 22mm in PCB) and is small enough to
placed on a robot for semiconductor machine vision inspection or placed in
an outdoor housing for remote surveillance. It is ideal for live visualization
and handheld instrumentation.
10-Bits Sampling – Sub-Pixel Accuracy
The SI-3300 MegaCamera uses 10-Bit digitizers to sample the pixel
data. Converting the pixel data directly to digital at the sensor head
eliminates pixel-sampling jitter and enables accurate sub-pixel metrology,
image analysis and improved live video reconstruction. A programmable
clock which ranges from 20~40Mhz or up to 80MHz with -H version, allows
for trade-offs in speed versus exposure time and lower noise.
Subsampling with Binning – Video Preview
Ideal for high speed preview and focusing, the SI-3300 is capable of
generating imagery at over 30 frames per second by reducing the size of
the readout image in color subsampling mode, This entire imager is
readout by binning 4x4 groups of pixels into 2x2 bayer super pixels with
increased sensitivity, less aliasing and faster readout rates. The camera
also supports up to 3x binning and 8x subsampling.
1000FPS Windowing and 720/1080P HD Modes
A small region of the imager can be readout at frame rates in excess of
1000fps, with speed increasing with reduced vertical and horizontal
settings. At 1920 x 1080 and a 75MHz clock the output rate would be
30fps or 1280x720 at 73MHz will be 60fps. The window size and position
can be adaptively changed on frame-by-frame basis.
Automatic Black Level Correction
The SI-3300 has automatic black level calibration, which measures the
average value pixels from two dark rows of the imager for each of the four
colors. The pixels are averaged as if they were light sensitive and passed
through the appropriate color gain. This average is then digitally filtered
over many frames and compared to minimum and maximum acceptable
thresholds for automatic correction.
CameraLink Digital Interfaces (12-Bit 1-Tap)
An industry standard forum has adopted Camera Link,
for low cost
connectivity and cabling of cameras and frame grabbers at very high
speeds. The SI-3300-CL utilizes the high speed CameraLink interface to
output data continuously to a frame grabber and directly into PC memory
for further processing. The single cable includes image data, synch,
Triggering and 9600 baud Serial communication. As this camera complies
with the standard, it is compatible with many popular frame grabber and
image processing hardware devices and GigaBit Ethernet or fiber-optic
repeaters for extended distance transmission.
