New CMOS sensor design provides performance
competition for high resolution CCD cameras
Featuring a unique 8-transistor architecture and providing a level of
image quality far beyond traditional CMOS cameras, the SP-20000-USB offers
16 fps at full 20-megapixel resolution (5120 x 3840) via a large 41mm
diagonal CMOS imager with global shutter. The camera
is available in both monochrome and colour versions, both models using
their architecture to implement true correlated double sampling (CDS)
for outstanding image quality with the highest degree of pixel uniformity.
This pixel technology is used in a variety of ways to make the image quality
suitable for many applications that may not have previously used
a CMOS-based camera
| Benefits and advantages | |
| High throughput | The SP-20000 provides high throughput of 20 megapixels at 16 frames-per-second without compromising image quality |
| High image quality | The combination of latest CMOS technology plus in-camera image preprocessing
provided a remarkably high image quality - well above that of typical
CMOS sensors and competitive with CCD cameras for many applications.
Incorporates correlated double sampling to remove reference voltage
variations - a technique not possible with less robust sensors and
resulting in pixel-level inaccuracies. On-chip routines and in-camera pattern correction algorisms minimise the appearance of fixed pattern noise usually found in CMOS imagers. |
| Large pixel size | The large pixel size of 6.4 µm facilitates the space needed for the 8T technology, providing the extra photosensitive area needed for better photon-capture for higher signal-to-noise ratio. |
| Global shutter advantage | The global shutter in the camera achieves a 50 000:1 parasitic light sensitivity rating – the highest among CMOS imagers where only 1 out of every 50,000 photons “leaks” into the output buffer. The less the leakage, the accurate the pixels. |
| Light adaptation | Combining the auto gain function with the auto shutter function, enables the camera to adjust to changing light conditions to provide optimal exposure while minimizing both image noise and motion blur. Extremely useful for outdoor applications |
| Build- ALC and HDR modes | Both modes are designed to handle difficult lighting situations.
The Automatic Level Control mode combines the auto gain function with the auto shutter function to handle change light conditions more easily while defining bosh the range and priority of shutter and gain variations - very useful in outdoor applications in particular. The built-in HDR mode captures both bright and dark details under high contrast conditions and provides outstanding low-light performance. (Monochrome only) |
| Industrial-grade construction | Built for the rigors of real-world applications by being able to withstand vibration and shock conditions of 10G and 80G, respectively |
| Thermal management | Advanced thermal management techniques enables the camera to operate in an extended temperature range of -45°C to +70°C. |
| Applications | ||||
| The SP-20000's high resolution means that large viewing areas can be inspected in a single pass instead of using multiple cameras or moving a camera mechanically It is ideally suited to applications that demand detailed, high quality images with the highest possible throughput. |
