Nikon Patents a Large Hybrid Viewfinder for Compact Cameras

nikontransparentvf

Electronic viewfinders have become all the rage as of late through the rise of the mirrorless camera, but many photographers still prefer optical viewfinders due to certain weaknesses of EVFs. One major drawback is the fact that the scene is often laggy, especially in low-light situations, making it difficult to track a moving subject.

Nikon is apparently trying to combine the best of the OVF and EVF worlds by developing a new giant viewfinder that’s see-through.

Toshiba Building a Lytro-like Smartphone Cam That Lets You Refocus Post-Shot

toshibalytro

Lytro is currently the only camera on the market that lets you refocus photographs after they’re shot, thanks to its fancy schmancy (and proprietary) light field technology, but it won’t be the only one for long. Toshiba is reportedly developing its own Lytro-style camera that will target a different segment of the photography market: smartphone and tablet photographers.

Apple Patents Method of Generating HDR Photos from Single Exposures

applehdrpatent

High dynamic range (HDR) mode is becoming a standard feature in newer digital cameras and smartphones. By snapping multiple photographs at different exposure levels, the camera can automatically generate an image that captures a greater range of light and dark areas than a standard photograph. However, the technique does have its weaknesses. Artifacts appear if any changes occur in the scene between the different shots, which limits the scenarios in which the technique can be used.

Apple wants to overcome this issue by implementing an HDR mode that only requires a single exposure. A recently published patent shows that Apple is well on its way to doing so.

Canon Patent Reveals a Smaller Optical Viewfinder with 100% Coverage

A Canon patent filed in May of last year and published last week reveals that the company has a new optical viewfinder up its sleeve that offers both a compactness and 100% coverage. While 100% coverage is a standard feature in high-end DSLRs, the new technology may help bring it to smaller and lighter cameras that have traditionally displayed less than what is actually captured.

CrowdOptic Discovers Islands of Popular Photo Subjects in Oceans of Images

We live in a world that’s teeming with digital photographs. More photos are now uploaded every two minutes than were created during the entire 1800s. Facebook is seeing thousands of photographs uploaded to its servers every second of the day, and Instagram was flooded with 10 storm-related photos per second during Hurricane Sandy.

With such a large quantity of photographs flooding the web, it’s clear that visual data mining will be an in-demand market in the coming years as more and more people look to glean valuable images from the torrent of useless pixels. One of the companies trying to occupy this space is CrowdOptic, a San Francisco-based startup that’s building some pretty interesting location-based photo curation technologies.

Sony’s ‘Smart Skin’ Camera Can See Zits Before They Appear

We’ve all used a little bit of Photoshop magic to take care of a blemish or two when taking portraits, but Sony’s newly announced Smart Skin Evaluation Program (SSKEP) is taking on blemishes in a whole new way. The sensor technology, which was announced just a few days ago, can actually go beyond skin-deep and take a peek at blemishes that haven’t even surfaced yet.

First-Ever Hyperspectral Photo of Auroras

Auroras are quite popular as a photo subject these days, especially for time-lapse photography, but a team of researchers in Norway recently snapped pictures of one in a way that hasn’t been done before: with a hyperspectral camera. The special device can simultaneously capture multiple spectral bands of light. The composite photograph above was created by combining three such bands of light, with each one assigned a different RGB color.

How Wearable “Sousveillance” Cameras Will Transform Our Society

Have you heard of the term sousveillance? It’s the inverse of surveillance: instead of a camera pointed at individuals, individuals wear their own cameras on themselves to document their activities. Wearable-camera pioneer Steve Mann has written a fascinating piece for Time, titled “Eye Am a Camera: Surveillance and Sousveillance in the Glassage“, in which he offers his vision of what the future will look like once wearable cameras such as Google Glass (seen above) become ubiquitous.

Scientists Building Security Cameras That Can “See” Crimes Before They Happen

Remember those weird floating “precog” psychics in the movie Minority Report? They could foresee crimes before they even happened, allowing law enforcement to prevent them from ever becoming a reality. While that kind of sci-fi foreknowledge will almost certainly never exist, scientists are working on an eerily similar system that uses cameras and artificial intelligence — a system that they hope will be able to “see” crimes before they even occur.
