12 megapixel billedsensor til industriapplikationer
CMOSIS introducerer nu 12 megapixel billedsensor, der sigter mod krævende industrielle anvendelsesområder (in english).
CMOSIS, a leading independent developer and supplier of high end CMOS image sensors for professional imaging applications, and TowerJazz, the global specialty foundry leader, announces CMOSIS will add a new member to its CMV CMOS image sensor family: The 12-megapixel CMV12000, which is manufactured in TowerJazzs Fab-2 in Migdal Haemek, using its advanced 0.18 m specialty CIS process.
The sensor features 5.5 x 5.5 m pixels laid out in a high-resolution 4096 x 3072 matrix resembling the APS-C format. CMV12000 offers high sensitivity and low noise, global shutter and a frame rate of 300 fps which provides best in-class performance.
The new CMOS sensor is perfectly suited for a broad range of industrial, movie and TV, traffic monitoring and motion control applications.
CMV12000 offers a dynamic range of 60 dB, extendable to 90 dB through several HDR (high dynamic range) operation modes. The sensor pixels have a very low parasitic light sensitivity (1:50,000) enabling high efficiency global shutter operation, which allows the sensor to capture extreme fast moving scenes without image distortion.
One of the unique features of CMV12000 is the novel pixel structure, which combines pipelined global shutter operation with correlated double sampling (CDS). This technique, pioneered by CMOSIS, yields an unprecedented low noise level below 13 e- and a full well charge of 13,500 electrons. The global shutter CDS also significantly reduces the sensor matrix's fixed pattern noise (FPN) for better image quality.
CMV12000s on-chip A/D converter can be operated at 8-bit, 10-bit or 12-bit resolution. In the faster 10-bit mode, 300 full frames per second are acquired. At 12-bit, CMV12000 still realizes a frame rate of 180 fps. The sensor's advanced architecture allows for row windowing and row sub-sampling. Up to 32 separate partial windows can be defined for an accelerated readout. Averaging several pixels raises these frame rates and increases the dynamic range.
The CMOSIS technology portfolio contains crucial IP related to various advanced aspects of image sensors among them high pixel counts at a high fill factor, high-speed functionality, large bit-depth of column ADCs, high dynamic range, TDI (time-delay and integration) implementation in CMOS and novel rad-hard pixel concepts.
