Sharp Corporation has developed a 3D camera module for mobile devices capable of capturing high-definition (720p*2) 3D video images, an industry first. Sharp will start shipping samples in July. Mass production of these modules will begin within 2010.
3D images are composed of two views taken using two cameras that simultaneously capture separate images for the right and left eyes. Consequently, a 3D camera requires peripheral circuitry to apply image processing to the two images, for example, to adjust color or to correct positioning between the images from the two cameras. Manufacturers have thus been pursuing designs that reduce the size and weight of 3D cameras and seeking ways to shorten their development period.
The current 3D camera module developed by Sharp incorporates functions to process the image data output by the left and right cameras, including Color Synchronizing Processing to adjust color and brightness, Timing Synchronizing Processing to synchronize the timing of the video signals, and Optical Axis Control Processing to correct positioning. In addition, Fast Readout Technology rapidly transfers video data from the image sensor, enabling 3D images to be captured in high-resolution HD mode. Further, in developing this camera module, Sharp applied high-density mounting technology to achieve a compact form. Embedding this camera module in mobile devices such as digital cameras, mobile phones, and smartphones will contribute to the development of a wide range of new, innovative communications tools.

Sony today introduced two innovative α series compact DSLR cameras -- NEX-5 and NEX-3 -- that provide the quality of a digital SLR in a compact body that is easy to slip into a small purse or a pocket. These models are the world s first interchangeable lens cameras with an APS-C sensor to continuously adjust focus and exposure while recording video. NEX-5 camera offers Full HD movie capture (1080i AVCHD and 720p MP4) with Full HD 60i recording.
Unlike conventional DSLR models, the mirrorless construction of the new models reduces the thickness of both camera bodies to just about an inch at their slimmest point (excluding grip and mount portions). NEX-5, constructed from magnesium alloy, and NEX-3, with a polycarbonate casing, offer a newly developed 14.2 megapixel Exmor APS HD CMOS sensor which is 60 percent larger than sensors in Micro Four Thirds cameras.
NEX-5 and NEX-3 are the first cameras to offer the extra convenience of high definition video recording. In addition to 720p HD recording, NEX-5 also captures Full HD (1920 x 1080i) video in high-quality AVCHD files that can be easily enjoyed on a compatible HD television via the cameras built-in HDMI terminal (cable not included). NEX-3 shoots 720p HD video as compact MP4 files. Both Sony cameras include built-in stereo microphones for high-quality audio recording.
Still and video image quality is further refined by Sony s powerful BIONZ processor that ensures quick DSLR-style shooting response with fast, precise autofocus and minimal shutter lag. Both cameras can also capture fast-moving action with a high-speed burst of full-resolution images at up to 7fps (AF/AE fixed from first frame).
NEX-5 and NEX-3 are the first cameras featuring Sweep Panorama. Capturing large group shots is as easy as press-and-sweep. Sweep Panorama mode lets consumers capture up to 226-degree horizontal or 151-degree vertical shots.
Both models will be ready for 3D Sweep Panorama this July (with firmware update). With 3D Sweep Panorama mode, these cameras can shoot 3D panoramic still images with a single lens. The high-speed burst of frames is stitched together using innovative processing techniques to automatically create detail-packed 3D panoramas. These files can be enjoyed in stunning 3D on compatible 3D televisions (other accessories may be required).
These cameras provide the advantages of multi-frame capture featured in Cyber-shot cameras, including Hand-Held Twilight and Anti-motion Blur modes, which offer improved low-light performance.
Images and camera settings are displayed on the 3-inch wide Xtra Fine LCD display with TruBlack technology and 921Kdot LCD that tilts up or down for comfortable viewing in any shooting position. The screen features an auto-brightness control function for excellent visibility, even outdoors. TruBlack screen technology enables an even more vivid, high-contrast view of images and camera settings.
Three new E-mount lenses are also being introduced, including a 16mm F2.8 wide-angle prime lens (P/N: SEL16F28), an 18mm-55mm F3.5-5.6 standard zoom lens (P/N: SEL1855), and an 18mm-200mm F3.5-6.3 ultrazoom lens (P/N: SEL18200).
All these new lenses have brushed aluminium barrels and steel mounts. An optional LA-EA1 Mount Adaptor extends compatibility to the family of 30 lenses, plus a huge range of other legacy A-mount lenses (manual focusing only).
Both cameras are supplied with a super-compact clip-on flash that attaches via the smart accessory terminal when needed. Other optional accessories include the FDA-SV1 Optical Viewfinder plus stylish cases and shoulder straps. As an option, the accessory shoe on both cameras accepts a compact ECM-SST1 Stereo Microphone that captures even more high-quality sound for HD video recordings than the cameras built-in stereo recording.
The new cameras accept both Memory Stick PRO Duo (including Memory Stick PRO-HG Duo) and SD (including both SDHC and SDXC) media. Sony's new Memory Stick PRO-HG Duo HX offers 30MB per second transfer rates.
NEX-5A and NEX-3A cameras, which are supplied with SEL16F28 lens, will cost about $650 and $550, respectively. NEX-5K and NEX-3K cameras, supplied with SEL1855 lens will cost about $700 and $600, respectively. NEX-3 will be available in silver, black and red, and NEX-5 in silver and black.
The SEL16F28 and SEL1855 lenses will be available for about $250 and $300. The SEL18200 zoom lens will be available this fall for about $800.
