NVIDIA Computational Zoom lets you change perspective and focal length in post

Researchers with the University of California, Santa Barbara and NVIDIA have developed a new type of 'computational zoom' tech that will let you change a photo's perspective and focal length in post.

Stanford develops extra-wide 4D light field camera... for robots

Researchers at Stanford have revealed a new '4D camera system' built for robots. The system is based on the same light field tech that allowed Lytro cameras to refocus images after they were taken.

Study finds most people can't spot manipulated photos, can you?

How confident are you that you can spot a manipulated photo? A recent study at the University of Warwick shows that many people are pretty bad at it.

New research on bee vision might help improve digital cameras

New research on how bees perceive color might some day revolutionize how digital cameras judge ambient light conditions, producing more realistic and consistent colors.

Google software engineer shows what's possible with smartphone cameras in low light

Google software engineer Florian Kainz wrote a custom Android app and used manual post-processing in Photoshop to show what's possible with current smartphone cameras in low light. Read more

Researchers create method for photorealistic Prisma-style effects

Prisma, but photorealistic rather than painterly: researchers at Cornell and Adobe have presented a new method that uses deep learning to transfer the style of one photo to another. Read more

This CMOS sensor with 3D-printed microlenses is designed to mimic predator vision

Using 3D printing to create ultra-precise micro-lenses directly on a CMOS sensor might one day help drones see the way eagles and other predators do. Read more

Google AI adds detail to low-resolution images

A new system by Google based on neural networking is capable of adding detail to very low-resolution images. Read more

Google uses neural networks to improve image compression

A research team at Google has developed a way to use neural networks to compress image files in a more efficient way than current methods by building an artificial intelligence system and training it with random images from the internet. Read more

Microsoft's MobileFusion turns smartphones into 3D scanners

A Microsoft prototype app allows for the generation of 3D models using your smartphone.

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.
