Nikon D600 Sensor Found by DxOMark to be “Elite” and 3rd Best Ever

Nikon’s new entry level full frame DSLR, the Nikon D600, is supposed to be a lightweight camera with heavyweight image quality. DxOMark confirms it to be true. The camera equipment measurement company has announced its sensor quality results for the D600, and the score is sure to put a big smile on the faces of Nikonians around the world. Rated at an overall score of “94″, the camera received the third highest score ever, and falls in third place behind the D800 and D800E — cameras that cost roughly $1,000 more.

Patent Shows That Nokia is Working on Graphene-Based Camera Sensors

Photos and details of Nokia’s upcoming Lumia 920 smartphone leaked earlier this week, revealing that the new flagship Windows phone will feature a 8-megapixel sensor, a 4.5-inch display, 32GB of storage, and wireless charging via a special pad.

Although the camera specs seem rather pedestrian compared to the 41MP 808 PureView, patents published last month reveal that the company is working on some special sensor tech for future devices. More specifically, Nokia is working on developing camera sensors that use layers of graphene — one-atom-thick layers of carbon — for big performance advantages over existing sensors.

Is This the Difference Between CCD and CMOS Camera Sensors? Nope

Virtually all digital still cameras capture light using either a CCD or a CMOS sensor. Most consumers don’t know the difference, and — given the rate at which CMOS sensors are improving — both sensors perform equally well in most cases (Leica is rumored to be switching over to the CMOS camp with its upcoming M10).

However, that’s not what a PC World store in Ireland wants you to believe. The photo above shows an informational placard that was on display recently in one of its stores. The top image shows a scene shot with a CCD sensor, and the bottom image allegedly shows the “same scene” shot with a CMOS sensor. Hmmm…

Unscrambling The Egg: The Leica M9 Monochrom

When Leica announced “Henri”, the M9 Monocrom on May 10th, it caused a lot of fervor on blogs and photography websites. The all black camera, named after the legendary black and white Leica photographer Henri Cartier-Bresson was devoid of almost all Leica markings and seemed niche even for the niche camera maker.

Panasonic May Be Working on a Sensor with a “Built-In Graduated Filter”

A new Panasonic patent uncovered earlier by Egami shows some exciting new sensor technology that may be heading our way soon. The new tech allows for the exposure values to be adjusted for each individual row of pixels. Essentially, the sensor could automatically apply a graduated ND filter to your images without the need for an actual filter. Read more…

OmniVision’s New Sensor Could Bring 4K Video to Your Next Smartphone

4K video is the realm of high end cinematography gear right? Maybe not. Two new 16MP sensors announced yesterday by OmniVision may be bringing smooth 4K video technology to everything from compacts to smartphones. The sensors, which are the tiny 1/2.3-inch format, can record 4K (3840 x 2160) video at 60fps, or even higher resolution (4608 x 3456) at 30fps.

The two sensors are no less powerful in the area of still photography either, being able to capture 12-bit RAW images. Of course your phone or camera processor will have to be able to handle the load, but newer devices with beefier image processors may well be sporting the new OmniVision sensors before long. Check out the press release for all of the juicy technical details.

Nikon May Turn to Aptina for Its Entry-Level Full-Frame Sensor

The latest rumor circulating around the “entry-level full-frame” topic is that Nikon may shying away from Sony when it comes to getting a full-frame sensor for the rumored D600. The rumor came as a result of an article on the Italian website MarsicaLive, which stated that Aptina Imaging is designing a new full-frame CMOS sensor for DSLRs; they also write that — according to unconfirmed rumors — the sensor is being designed specifically for Nikon. Although this is the first full-frame sensor designed by Aptina, Nikon is already familiar with the company as the V1 mirrorless camera already uses one of Aptina’s sensors.

DxOMark: Canon 5D Mark III Sensor Best Among Canons, Falls Short of Nikon

Camera rating business DxOMark has published its in-depth sensor review for the Canon 5D Mark III. For Canon fans, there’s both good and bad news: while the camera boasts the best sensor seen in a Canon DSLR so far — besting the sensor found in the 1Ds Mark III — its score of 81 is far below the Nikon D800′s 95. DxOMark does, however, point out that the two cameras focus on different strengths:

The duel between the Nikon D800 and the EOS 5D Mark III would most certainly take place except that the different sensors each one has adopted makes it difficult to do a head-to-head comparison. Both sensors offer different advantages —in principle, sensitivity for the Canon and definition for the Nikon. With its 36 megapixels, the Nikon D800 clearly has concentrated its efforts on fine detail reproduction.

For its part, the Canon EOS 5D Mark III chose to make a grand compromise: with its 22 megapixels, it offers both higher definition and in theory, higher sensitivity.

Advanced Image Sensor Concepts Explained with Beer

When German image sensor scientist Joachim Linkemann gave a talk called “Advanced Camera and Image Sensor Technology” at Automate 2011 back in March 2011, he tried to boil things down to terms people could understand and ended up using beer to illustrate the concepts. If you want to learn about how things like signal-to-noise, dynamic range, and dark noise would work if a glass of beer was the pixel on an image sensor, check out the PDF slideshow.
