Sony Debuts Digital Still Camera with Back-Illuminated ‘Exmor R’ CMOS Sensor

Technology.am (Aug. 8, 2009) — Sony unveiled two new Cyber-Shot Digital Still Cameras, DSC TX1 and DSC-WX1 models that provide unprecedented advances in low-light performance with approximately twice the sensitivity of cameras with traditional image sensors.

Conventional image sensor architecture has required wires and other circuit elements to be positioned above the light sensitive photo-diodes, limiting the imager’s light gathering capability. Positioning these elements behind the photo-diodes, Sony’s “Exmor R” image sensors can gather more light, resulting in approximately twice the sensitivity compared to conventional sensors.

To further extend low-light shooting performance, the TX1 and WX1 cameras incorporate the hand-held twilight and anti-motion blur multi-shot modes introduced in Sony’s breakthrough Cyber-shot DSC-HX1.

Using “Exmor R” CMOS sensor’s high speed, these modes capture six separate images in less than a second and utilize Sony’s BIONZ processor to combine the shots into a single image of extraordinary detail and low noise.

Combining the “Exmor R” technology with hand-held twilight and anti-motion blur modes delivers a breakthrough in low-light photography.

Using the high-speed “Exmor R” CMOS sensor, the cameras shoot continuously while you sweep across the scene. Using the BIONZ imaging processor, they automatically stitch the pictures together to create one stunning panoramic photo.

With a Carl Zeiss Vario-Tessar lens, the TX1 camera lets you focus as little as 0.4 inches from your subject for extraordinary close-up shots.

These cameras include the most recent Sony technology, including, Intelligent Auto (iAuto) mode which, recognizes scenes, lighting conditions and faces, and adjusts settings resulting in clearer images, faces with more natural skin tone and less blur; Face Detection that detects up to eight faces and optimizes focus, flash, exposure and white balance and intelligent Scene (iSCN) that delivers nine Scene Selection modes to quickly adjust for specific shooting conditions.

The TX1 camera will be available this September for about $380. The WX1 camera will be available this October for about $350.
