Kodak Announced 29MP W-RGB Interline Transfer CCD

Kodak announced KAI-29050 claimed to be the highest resolution CCD based on Interline Transfer technology. The 35mm optical format CCD is based on 5.5um pixels and features TRUESENSE W-RGB filter pattern to enhance low-light sensitivity.

This 35mm format CCD is the 7th in Kodak's family 5.5um pixel devices, a family that includes an entire set of image sensors from 1 to 29 megapixels. The KAI-29050 joins two other products - the 720p format KAI-01150 and the 1080p format KAI-02150 - as the first devices to use the KODAK TRUESENSE Color Filter Pattern. The TRUESENSE technology is claimed to provide a 2x to 4x increase in light sensitivity compared to a standard Bayer color sensor by adding panchromatic pixels to the standard RGB elements that form the image sensor array.

The KODAK KAI-29050 Image Sensor is sampling today in limited quantities, with production scheduled for mid-2011. The KODAK KAI-01050 and KAI-02050 Image Sensors are available today in PGA packages, with CLCC packages scheduled to be available Q1, 2011.

CMOSIS and TowerJazz Announce 12MP/300fps Global Shutter Sensor

Business Wire: CMOSIS and TowerJazz announced 12MP CMV12000 featuring global shutter and a frame rate of 300 fps, said to be best in-class performance. The off-the-shelf image sensor is manufactured in TowerJazz’s Fab-2 in Migdal Haemek, Israel, using its advanced 0.18 µm specialty CIS process. The sensor features 5.5 x 5.5 µm pixels laid out in 4096 x 3072 matrix resembling the APS-C format.

CMV12000 offers a DR of 60 dB, extendable to 90 dB through several HDR operation modes. The sensor pixels have a very low parasitic light sensitivity (1:50,000) enabling high efficiency global shutter operation. One of the unique features of CMV12000 is the novel pixel structure, which combines pipelined global shutter operation with CDS. This technique yields an low noise level below 13 e- and a full well of 13,500 electrons. The global shutter CDS also significantly reduces the sensor's FPN.

CMV12000’s on-chip ADC 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.

We highly value our partnership with TowerJazz and its advanced CMOS imaging technology for our innovative products due to the success we have achieved throughout our collaboration. Due to the maturity of their process technology, combined with the design flexibility that they offer, we are able to realize stronger and more reliable performance,” said Luc De Mey, CMOSIS CEO. “In addition, TowerJazz’s long-term investment in R&D and their excellent technical support keeps us at the cutting edge.

By combining our worldwide recognized leadership in CMOS sensors and pixel technology with CMOSIS’ many years of experience in CMOS image sensor design, we are equipped to meet the market’s demanding requirements for leading-edge performance, advanced features and reduced die size and price. Together, we are well-positioned to win a significant share of future industrial and professional CMOS image sensor markets,” said Avi Strum, VP and GM of TowerJazz’s Specialty Business Unit.

The new CMOS sensor is suited for a broad range of industrial, movie and TV, traffic monitoring and motion control applications. The Total Addressable Market for industrial sensors is estimated at $750M, out of which the machine vision sensor market is estimated at $200M, according to a report titled, “The Future of Image Sensors Market and Technology Forecasts to 2014,” by Roy Szweda.


Update: As written in comments, the sensor is based on 8T pixel to realize a high-quality fully pipelined global shutter with low parasitic light sensitivity. All 8 transistors together with two storage caps are squeezed into 5.5um FSI pixel in 0.18um process - the pixel layout must be a masterpiece!

There is a nice CMOSIS presentation describing the pixel operation and advantages, presented on Image Sensors Europe conference in March 2010. The 8T pixel operation principle is explained below:

Image Sensor Implant Restores Partial Sight

Electronics Weekly, BBC News: German firm Retina Implant reported testing results of the chip that has restored limited sight for people blinded by retinitis pigmentosa and similar diseases, destroying only the eye's photoreceptors, and leave its layers of image processing neurons intact.

The chip, which is 3mm across and 50µm thick, has a 70µm pitch 40x40 photodiode array, plus a corresponding electrode array. The implant can both receive images focused by the eye's existing optical system, and inject signals directly into the original neurons. The chip includes signal conditioning, and has to receive power provided along a cable that exits through the side of the eyeball and is led to an inductively coupled power receiver under the skin near the subjects ear. The microchip yields a visual field of about 12°, allowing mobility and object recognition in space.

Thanks to CDM for sending me this news!

Update: EETimes reports that Retina Implant AG has opened a manufacturing plant to meet anticipated demand for its devices. The new manufacturing plant is 312 sq.m and located in Technology Park, Tubingen-Reutlingen, Germany. Of this, about 100 sq.m is for a clean room, with the capability to increase its size to 250 sq.m. The manufacturing capacity is estimated to be 1,500 sub-retinal implants per year and Retina Implant is planning to invest another 1.3M euros to equip the building.

Retina Implant was founded in 2003 by Dr. Eberhart Zrenner and his colleagues in 2003, after extensive research with German university hospitals and institutes which began with a large grant from the German Federal Ministry of Research and Education in 1996. Retina Implant began implanting in human patients in 2005.

Although the vision that results is relatively low resolution it allows mobility and some object recognition in space according to the company. There is the possibility of improving the resolution of implants in the future.

SiOnyx Talks About Testing

Test and Measurement World published an interview with SiOnyx test engineer. Not much interesting stuff there, other than performing tests with a "monochrometer" and an unusual explanation of blooming:

"I use my background in physics and fiber optics to suggest tests to the designers. For example, I may recommend testing using both pulsed and continuous light. Using pulsed light lets you see how long a device takes to respond. This kind of testing is important for sensors, because of possible "blooming." That is, if the response is too slow, residual signal from a sensor's response will add to that of the next sample, producing an error."
