20 Megapixel imagesensor til industriapplikationer
Det belgiske firma CMOSIS, der har specialiseret sig inden for image sensorer til industriapplikationer, lancerer 20 MP version til de mest krævende applikationer (in english).
CMOSIS, one of the leading suppliers of CMOS image sensors forindustrial 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.
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.
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.
