Nikon has signed a licensing deal with Microsoft to cover the use of patented technologies in its Android-based cameras. The deal is the latest instance of Microsoft pursuing makers of Android devices, claiming patent infringement. Despite free access being one of the founding ideas of Google's Android operating system, Microsoft has been increasingly successful in convincing manufacturers of Android devices that they need to strike licensing deals for some of its technologies.

A project at the Massachusetts Institute of Technology has embedded advanced processing functions into an image processor for mobile devices. The chip includes features such as 'real-time' HDR processing and sophisticated bilateral noise reduction at a hardware level - making the process more energy efficient than running it as software, and making the chip more appropriate for battery-limited mobile devices. The work was funded by iPhone manufacturer Foxconn and a prototype chip, fabricated by the Taiwan Semiconductor Manufacturing Company, is now being tested.

Sigma USA has announced the price and availability of its DP3 Merrill large sensor, fixed lens compact. The camera will be available from March 2013 at an estimated street price of $999.

Just Posted: We've had a chance to get our hands on the Nikon D7100 - the company's latest mid-range DSLR. The D7100 looks a lot like the popular D7000 but has been completely overhauled internally. Central to its feature set is a 24MP CMOS sensor with no optical low-pass filter, promising high resolution captures. It also gains a 51-point autofocus system and 1.3x crop mode for both stills and video capture, amongst other upgrades. Click here to find out what we thought.

Nikon has just posted a small 6-image sample gallery from the new D7100. The D7100 is a 24MP, APS-C DSLR that does not feature an optical low-pass filter on its sensor. Theoretically, this should increase detail resolution. As well as an unconventional sensor, the D7100 offers a 51-point AF system and a 1.3X crop mode in stills and video capture. The images that Nikon has posted were taken in .NEF Raw mode with the D7100 fitted with the AF-S NIKKOR 500mm f/4G ED VR and AF-S NIKKOR 70-200mm f/4G ED VR.

Nikon has announced the D7100 - a 24MP mid-range, enthusiast-focused APS-C DSLR. The D7100 promises high resolution by making do without an optical low-pass filter in front of its 24MP CMOS sensor. It gains a more sophisticated 51-point autofocus system and a 7fps 1.3x cropped shooting mode that provides a 2x crop compared to a 35mm system. The D7100 has a recommended price of $1,599/£1,299/€1,399 with 18-105mm F3.5-5.6 VR lens.

Alongside the D7100, Nikon announced the WR-1 Transceiver, a unique radio-frequency wireless remote control. Able to remotely control multiple cameras capturing stills and videos, and even time-lapse sequences, the Nikon WR-1 Transceiver mounts on the camera's hot shoe, but communicates via a cable attached to the master camera. Expected to retail for £649.99 in the UK, the WR-1 will ship in March 2013 (US pricing has yet to be announced).

A new, smaller capacitor could make Xenon flashes practical for use in ultra-slim smartphones. Researchers from a university in Singapore have partnered up with Xenon Technologies to develop a tiny capacitor for Xenon flashes that it claims is just as powerful as existing, larger versions. This is potentially big news for the smartphone industry which has primarily used LED lights in preference to Xenon flashes up to now. Few smartphones have incorporated Xenon flashes because of their higher power demands and larger physical size. Learn more about the tiny new capacitor at connect.dpreview.com.

A 320-gigapixel image taken from top of London's BT Tower has set the world record of the largest panoramic photo. It breaks the previous record set by a 281-gigapixel electron micrograph of a zebrafish embryo taken in 2012. The London image was shot by panorama specialists 360 Cities and is made up of 48,640 individual frames. To get an idea of just how large this photograph is, BT says if it was printed at 'normal resolution' the photo would measure measure 98 x 24 metres.Click through for pictures and more information on the hardware used to make the image.

Much ado has been made about the sensor technology rumored to debut along with HTC's newest handset launched today, the HTC One. While rumors of stacked sensors were predictably wide of the mark, HTC is taking a clever approach to improving camera phone quality by betting on fewer but larger pixels captured by a 4.0MP 1/3" sensor, which are similar in size to those found in enthusiast compact cameras, and which HTC is calling 'ultrapixels'. Combined with a fast F2.0 lens and optical image stabilization, the HTC One's specs hold promise for better low-light photography - an area where mobile phones have fallen notoriously short.

Dozens of two-dimentional aerial photo calibration targets are scattered all across the United States, according to a report by the Center for Land Use Interpretation. Constructed mostly during the 1950s and 1960s, these large outdoor charts were used as 'a platform to test, calibrate, and focus aerial cameras traveling at different speeds and altitudes.' The report points out that although some of these 'charts' are still used for some optical camera testing and calibration, they are primarily relics of the past.
