SAN DIEGO, Aug. 5, 2009 – Sony today announced two new Cyber-shot® 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.
These Cyber-shot cameras are the first to employ Sony’s new “Exmor R” back illuminated CMOS sensor technology to improve shooting in low-light scenarios, enhancing image clarity and drastically reducing grain.
“With these new “Exmor R” CMOS sensor cameras, Sony has vastly improved the customer experience for taking pictures with digital still cameras in low-light scenarios,” said Phil Lubell, director of the digital imaging business at Sony Electronics. “We’ve all taken pictures in dimly lit areas, where the results were grainy and unclear. By redesigning the way these cameras capture light, Sony is leading the industry by creating this easy way to take amazingly clear, vibrant photos in low lighting scenarios.”
“Exmor R” Sensor Optimizes Low-Light Performance
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.
