Researchers in Tokyo develop high-speed subject tracking system

Engineers at Tokyo University's Ishikawa Oku Laboratory have come up with new technology to track extremely fast motion. Their new system - which uses 'Saccade Mirrors' for pitch and tilt, a 'pupil shift system', and very fast image processing - is able to keep even the quickest subject in the center of the frame at all times. According to engineers, the initial application for this system could be to capture video at sporting events. They expect it to be market-ready in about two years. Follow the link for a video demonstration of this intriguing new technology.

New study investigates online reviews - makes surprising discoveries

Online product reviews are a huge part of our lives these days, and often, they're the nearest thing we get to a 'hands on experience' before we buy something. But how do we know they're honest? Dishonest reviews are a serious problem for retailers (and indeed for content websites like dpreview.com) and a team at the Massachusetts Institute of Technology has been investigating why people are driven to leave reviews of products that they haven't actually used. Their findings might just surprise you. Click through to read more.

Engineers eye-up insect biology as inspiration for curved camera

Engineers have developed a curved camera designed to mimic insects' compound eyes. The hemispherical design gives a wide field-of-view with no aberrations and effectively infinite depth-of-field, with the hope it could be used in applications such as endoscopy or as visual sensors on unmanned aircraft. The current design uses 180 light-sensitive elements, each behind its own lens, but researchers hope to build one with 20,000 elements, giving a similar resolution to that seen by dragonflies.

Scientists demonstrate 'paint-on' batteries

Scientists in Texas have demonstrated a way of 'painting' rechargeable lithium-ion batteries onto surfaces, greatly expanding the potential for future development of portable electronics. The team, from Rice University, has succeeded in painting batteries onto a range of different surfaces, including common household objects, with 'no surface conditioning'. The batteries are made up of five layers measuring just 0.5mm thick in total and, according to the scientists that developed the technology, can be fabricated using conventional spray-painting equipment and techniques.

One-shot gigapixel camera offers a future beyond flat sensors

A gigapixel camera developed for the US Department of Defense's research agency provides an insight into the challenges that will need to be overcome to offer super-high-resultion cameras. A team from Duke University, Durham, North Carolina, has described its 960 megapixel (0.96 gigapixel) 'AWARE-2' camera in a letter to scientific journal Nature. The team says small, efficient electronics are the key to being able to miniaturize the camera, which currently sits in a 0.75 x 0.75 x 0.5m frame.

Scientists develop flexible sensor to allow simple zoom

Scientists have successfully constructed a digital camera that can be flexed to focus an image, allowing its use with simple single-element lenses. Researchers from Northwestern University and the University of Illinois at Urbana–Champaign created a 16 x 16 pixel array on an elastomeric backing that can be distorted to correctly focus the image from a simple lens. In a paper to be published in the Proceedings of the National Academy of Sciences (PNAS), they combine this with a single-element, tunable lens to provide a camera with very simple optics capable of zooming. The technology could eventually provide 'studio quality' images from cellphone cameras, one of the lead researchers says.
