World's biggest CMOS sensor could help doctors detect and treat cancer

Move over, Canon, because scientists at the University of Lincoln have just seized the crown for world's biggest CMOS image sensor with their new Dynamic range Adjustable for Medical Imaging Technology microchip -- or 'DyNAMITe,' for short. Measuring a hefty 12.8 square cm (or about five square inches), DyNAMITe is roughly 200 times bigger than the chips you'd find in most PCs, making it the largest imager ever made on a wafer of standard, eight-inch diameter. This extra girth allows the active pixel sensor to capture images in high detail, with a 100-micrometer pitch boasting 1280 x 1280p aligned next to a 50-micron layer, carrying 2560 x 2560p. DyNAMITe can also run at up to 90fps and withstand high levels of radiation for several years, making it ideal for medical imaging, including radiotherapy and mammography. Researchers say these enhanced images could help doctors detect cancer in its earliest phases, while allowing them to monitor radiotherapy treatments more c...

Sony shoots out CineAlta F65 4K camera and PMW-TD300 3D camcorder at NAB

The current trend in the world of home theater may seem like 3D cinematography is all the hype these days, but Sony's latest imager in its CineAlta family begs to differ. Unveiled at the 2011 NAB Show, this F65 mammoth camera (pictured right) packs one beastly 20.4 megapixel, Super 35mm CMOS sensor -- a huge leap from the F35's 12.4 megapixel 1080p CCD. Aside from the obvious quantitative difference, what's special about this new chip is that unlike the Bayer BG-GR subpixel matrix on conventional 4K sensors, here we have green pixels forming the 4K grid while an RB-BR matrix fills in the space, thus doubling the number of horizontal pixels to 8K for a finer 4K picture (see illustration after the break), as well as allowing better visual effects editing using the extra data. What's more, this sensor is fast -- not only can it capture up to 72fps on 4K, but it can also crank up to a smooth 120fps on 2K. As for those seeking to squeeze out every bit of detail ...
