CMOSIS Introduce 20-Megapixel
Image Sensor For Industrial Application
Published on June 29, 2012 at 6:30 AM
CMOSIS, one of the leading
suppliers of CMOS image sensors for industrial applications, today introduced a
20-Megapixel image sensor for demanding, industrial applications. With the
introduction of the CMV20000, CMOSIS broadens its current CMV portfolio of high-performing
global shutters CMOS image sensors addressing the high-resolution segment of
the industrial vision applications as well.
The unique properties and
features such as high resolution, high dynamic range and global shutter, are a
perfect fit for high-end industrial imaging systems, automation systems and
medical applications.
The CMV20000 image sensor
features a 20 Megapixel (5,120 x 3,840) resolution with 6.4 um sized square
pixels resulting in an active sensor area of 32.8 x 24.6 mm (35 mm film optical
format). Peak quantum efficiency reaches up to more than 45 percent resulting
in a superb responsivity of 8.29 V/lux.s in combination with an excellent
dynamic range of 66 dB. By means of correlated double sampling in global
shutter mode, the patented 8-transistor pixel cell architecture reduces any
dark noise and FPN non-uniformity of the sensor matrix. The sensor also offers
an excellent shutter efficiency, a common feature of the CMV image sensor
family.
The CMV20000 image sensor features a 20 Megapixel resolution with
6.4 um sized square pixels.
At full 20 Megapixel
resolution and with a 12-bit ADC resolution the CMV20000 delivers 30 full
frames per second. This is achieved by using 16 LVDS outputs running at 480
Mbit/s each. Lower frame rates can be supported by multiplexing to 8 output
channels only. Partial read out, windowing and subsamples modes, can be
programmed to support higher frame rates. At full resolution and frame rate,
the power dissipation is 1.1W. This power consumption can be dynamically
controlled when lower frame rates are used.
Driving and programming the
on-chip features such as HDR (High Dynamic Range) modes, offset and gain
programming and power dissipation control is done over a 3-wire read-write SPI
control.
The monochrome variant of the
CMV20000 image sensor is in production today. A color variant, with RGB Bayer
CFA filter, will be introduced to the market in Q4 2012. It is housed in a
ceramic 143-pin PGA package and can be operated in the -20 to +70 ºC
temperature range. This extended temperature range makes the CMV20000 perfectly
suited for most demanding and robust industrial applications.
The CMV20000 was originally
developed as a customized, exclusive product aimed at complex traffic
management applications. An agreement with the original customer allows CMOSIS
to offer this imager to third parties for applications outside the traffic
field.
