Sony Electronics Inc. has today announced its first two digital still cameras to feature its back-illuminated 'Exmor R' CMOS image sensor, the Sony Cyber-shot DSC-TX1 and Sony Cyber-shot DSC-WX1.
Most current imagers used in digital cameras are front-illuminated, meaning that light must pass through a metal wiring layer before arriving at the photodiodes. A significant portion of the light is blocked by this wiring layer, and hence the ability of the sensor to gather light is reduced. By contrast, back-illuminated sensors place the wiring layer below the photodiodes, enabling more light to be collected. This improvement, says Sony, means a 200% increase in the sensitivity of its Exmor R chips over a traditional front-illuminated CMOS sensor. To look at things another way, that's a 50% decrease in noise levels at the same sensitivity, given that in amplifying the signal from a less sensitive sensor, you're simultaneously amplifying noise at the same time. The Sony TX1 and Sony WX1 aren't the first products to use Sony's Exmor R sensors - the company first launched the chips in its camcorders back at the Spring 2009 Photo Marketing Association tradeshow - but it's the first time that Exmor R has been featured in a Cyber-shot still camera. In other areas, the Sony DSC-TX1 and Sony DSC-WX1 bring features from the company's popular HX1 model into more compact bodies. The Cyber-shot WX1 is the more affordable of the pair, and is aimed at those whose key focus is on the the camera's photographic capabilities - DSLR owners looking for a pocket-friendly second camera, for example. The 0.8-inch thick Cybershot WX1 is just slightly larger and heavier than its sibling, but offers a Sony G-branded 5x optical zoom lens that yields the range from a generous 24mm-equivalent wide angle to a 120mm-equivalent telephoto. Maximum aperture for the Sony WX1 varies from a bright f/2.4 at wide angle to f/5.9 at telephoto. The DSC-WX1 also offers a higher maximum shutter speed of 1/1,600 second, and a greater battery life of 350 shots per charge. By contrast, the slightly more expensive Cyber-shot TX1 is aimed at the fashion-conscious photographer, and features a stylish 0.7-inch thick body that's overall slightly smaller and lighter than its sibling. The TX1 has a less powerful Carl Zeiss Vario-Tessar branded 4x optical zoom lens which offers focal lengths ranging from a more pedestrian 35mm wide angle to a 140mm telephoto. Maximum aperture varies from f/3.5 to f/4.6 across the zoom range. The DSC-TX1 has a maximum shutter speed of 1/1,250 second and a battery life of 250 shots per charge. The Sony TX1 brings its own special feature to the table though... Where the WX1 offers a 230,000 dot 2.7-inch Clear Photo LCD on which images must be framed - there being no optical viewfinder on either camera - the Cybershot TX1 upgrades this to a larger and more versatile 3.0-inch Clear Photo Plus LCD touch screen of identical resolution. The Sony Cybershot DSC-TX1 will be first to ship in the US market this September, with four body colors available - silver, gray, pink or blue. Pricing for the Sony TX1 is set at $380. The Sony Cybershot DSC-WX1 will follow from October 2009, and will only be available in a black-bodied version for the US market. Sony WX1 pricing has been set at $350.

Original Source Press Release:
Sony Debuts World’s First Digital Still Cameras With Back-Illuminated “Exmor R” CMOS Sensor Technology New Cyber-shot® Cameras Excel in Low-Light Performance 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 situations, like blowing out candles on a birthday cake, and 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. Combining the “Exmor R” technology with hand-held twilight and anti-motion blur modes delivers a breakthrough in low-light photography. Users can now capture images of stunning detail and low noise in scenes with no more than candlelight—without flash or the need of a tripod. Innovative Sweep Panorama™ and High-Speed Shooting In addition to their breakthrough low light performance, these new cameras also include Sony’s Sweep Panorama and 10 frames per second burst shooting features, which were introduced with the Sony® DSC-HX1 camera. The TX1 and WX1 cameras offer these features in smaller, more compact bodies that match nearly any unique style. Capturing wide landscapes is as easy as “press and sweep.” Sweep Panorama mode lets you reach beyond the traditional wide-angle lens and capture breathtaking shots. 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. The TX1 and WX1 Cyber-shot models can take up to 185 and 256-degree panorama shots respectively in one easy press-and-sweep motion with an image size of 7152 x 1080 (ultra wide horizontal). Advanced Technology and Compact Design While the HX1 camera is a well-rounded solution for customers who are looking for high-zoom and speed in a smaller size than a DSLR, the TX1 and WX1 cameras are made for an audience that wants advanced technology in an even more compact design. With its slim profile of just 16.5mm, the 10.2 mega-pixel TX1 offers streamlined, distinguished curves for a sophisticated look appealing to the fashion-oriented who are also looking for great performance. This model features a new operation on the touch panel that lets you scroll through images with an effortless “flick” of your finger and directly access menus on the 3-inch Clear Photo LCD Plus™ display. 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. The 4x telescopic zoom is perfect for capturing far-away subjects, and Sony’s Optical SteadyShot™ image stabilization helps overcome camera shake. The 10.2 mega-pixel WX1 camera has a 2.7-inch Clear Photo LCD Plus display and is just over three quarters of an inch thin—an ideal choice for DSLR owners who also want to carry a compact, high performance digital still camera. The WX1 camera features a Sony G lens with an extraordinary wide angle 24-120mm 5x optical zoom. This lens’ f/2.4 maximum aperture offers nearly twice the light gathering capability of conventional lenses, and works together with the “Exmor R” imager and low-light shooting modes to provide low-light photography beyond the abilities of other compact cameras. Tech Savvy Cameras 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. Pet mode is a new Sony feature that minimizes blur when shooting moving pets. This new mode also reduces glowing pet red-eye. Additionally, the cameras have technologies Sony Cyber-shot customers have come to expect. These include Smile Shutter™ technology that automatically captures a smile, dynamic range optimization (DRO) that improves exposure and contrast, intelligent Auto Focus that captures fleeting moments and HD video capability that records HD movies in 720p high definition MPEG4 format. With HD video capability, these cameras record HD movies in 720p high definition MPEG4 format for stunning large-screen home movie playback. You can record up to 29 minutes (or up to 2GB file size) in 720p format. Pricing and Availability The TX1 camera will be available in silver, gray, pink and blue this September for about $380. The WX1 camera will be available in black this October for about $350. Pre-sales will start in August. The cameras and a range of accessories will be available online at sonystyle.com, at Sony Style® retail stores (www.sonystyle.com/retail), at military base exchanges and at authorized dealers nationwide. ### Editor's Note: News releases and digital images with captions are available at www.sony.com/news.
