Toshiba Announces 1080p60 HDR Sensor

PRNewswire: Toshiba announces its newest device for the security/surveillance and automotive markets, a full HD (1080p) CMOS image sensor with 100dB DR, frame rate of 60fps, pixel size of 2.7um, and color noise reduction in low-light conditions (CNR). The TCM5117PL 1/3-inch sensor is aimed to security/surveillance cameras and automotive systems.

Toshiba's single-frame, alternate-row, dual-exposure HDR implementation in the TCM5117PL is better suited for capturing fast-moving objects compared to conventional multi-frame systems. With frame rates at 30fps for conventional multi-frame systems, the single-frame approach, at 60fps, promotes faster, less blurry images in high-contrast light conditions. The TCM5117PL is designed for long-term use, operating 24 hours a day.

The TCM5117PL has a 3.3+/-0.3V single-power supply and comes in a 10.5 ×10.0 mmP-FLGA80 package. The device supports RAW10/RAW12 data formats.

Samples of the TCM5117PL sensor are available in Q2/2013. Mass production is scheduled for Q3/2013. Sample pricing is set at $35.

    How is it possible to do alternate row 1080P HD video with 2.7um pixel in 1/3rd inch optical format?

    Are we looking at a effective pixel pitch of 5.4um?

    I guess that there should be some artefacts on the image. If both rows give useful information, then the resolution is roughly conserved. But if one row is saturated and the other not, then the resolution is halved. When Bayer's filter is used, this becomes complicated indeed.

    SNR of this product is 50dB ( http://www.toshiba-components.com/cmos/cmos-auto-surv.html ). This corresponds to a Full well Charge of 90ke-. This seems to be too much for a 2.7um pixel.

    Can some one throw some light on this..

      SNR doesn't increase with HDR....

      Good find on the specs! I was hoping for much higher pixel count - at least double 1080p (Sony did it right with Exmor RS http://www.sony.net/SonyInfo/News/Press/201208/12-107E/ ). 100dB is a best case scenario of combining 50dB short exposure with 50dB long exposure.

      Indeed strange datasheet. Probably that 50dB SNR was meant to be 50dB DR. But then if you combine the 50dB of the short exposure with the 50dB of the long exposure, the SNR drops at 0dB at the switching point between long and short exposure which would make the sensor unusable..Anybody can clarify on this?

    Yes Sony and Aptina have it right with HDR sensors both small and large pixel HDR solutions.
