Whether you're one of the 10 million who bought a Kinect or one of those who mock its existence, there's no denying that Microsoft's Xbox 360 motion control device is doing more than letting players tickle digital tigers.

Using the camera and motion recognition built into the accessory, the techies at Triangle Productions are using a hacked Kinect to make a motion capture--or "mo-cap"--movie. They're utilizing the professional animation programs Maya and MotionBuilder, open-source programming software OpenNI, and a Kinect tool called Brekel, to capture their own actions, which characters then mimic in "Under the HUD," a new animated Web series.

In the process, they've probably saved themselves from spending sleepless nights animating frames while creating what looks to my eyes to be high production value--at what's most likely a fraction of the cost.

While the Web series hasn't aired yet (the creators are aiming for an early-May release), the sneak-peek video below details the production process, as well as the mo-cap capabilities of Kinect.… Read more

In an effort to keep eyes on the road and hands on the wheel, researchers at the German Research Center for Artificial Intelligence are working on new technology that could let drivers control their vehicles' in-cabin systems with a just a wave of a finger.

Geremin is a multimodal interaction technology that enables drivers to control temperature, volume, and entertainment systems using gestures. As infotainment systems become more complex and cars pull double duty as mobile offices, dashboards and steering wheels will become overloaded with buttons. Finger gestures give drivers a new way to communicate with the vehicle without taking … Read more

Phase One, the Danish maker of high-end digital camera gear, announced a new top-end product: an image sensor with a whopping 80 megapixels.

The IQ180 is a digital back, which consists of an image sensor, viewing screen, and associated electronics housed in a removable module that fits on the back of a medium-format camera body such those from Phase One-controlled Mamiya. The medium-format market, which consists largely of photographers shooting expensive subjects such as fashion models and jewelry, is a demanding one willing to pay a premium for the very detailed images made possible with medium-format gear. Phase One's … Read more

Apple's iPhone 4 camera packs a technology that a lot of buyers of the phone may have missed: a new image sensor tech that is coming into focus--pardon the pun--as camera makers like Kodak adopt the technology in higher-end cameras.

The technology, called backside illumination, or BSI, was highlighted by Steve Jobs when he took the stage to roll out the new iPhone, as Joshua Goldman of CNET Reviews wrote here.

Apple's savviness shines through here. The company had to do its homework to get out in front of this trend, particularly in smartphones, which are not necessarily … Read more

Consumer electronics company E Fun is bumping up its lineup of Android tablets.

Appearing at CES this week, E Fun will be demoing its new Next4, Next5, and Next6 tablets, all with built-in Wi-Fi and access to the Borders e-book store.

Running Android 2.2, the 10.1-inch Next4 will retail for $349.99, while the Android 2.1-equipped 7-inch Next6 will cost consumers $269.99. Both models include 2GB of memory, an SD card slot, a viewer for MP3 files and photos, built-in speakers, 25 pre-loaded books, and a G-sensor accelerometer that reacts when you tilt and move the … Read more

As consumer demand for cameras continues to rise, Sony plans to invest $1.2 billion next year to double its production of the image sensors used in smartphones and digital cameras.

The Japanese electronics giant announced today that part of the investment would go toward buying back a semiconductor production line from Toshiba, a deal estimated to cost around $600 million, according to an industry source cited by Reuters. The company is also planning to convert part of a plant in Nagasaki to make CMOS (complementary metal-oxide semiconductor) sensors and will purchase wafer processing equipment for CMOS image sensors, Reuters … Read more

Some Apple employees are apparently having fun sending pictures of internal policy documents to the Boy Genius Reports tech Web site. Recently, a screenshot of Apple's LCD replacement policies surfaced on the site, and currently another is available, which shows changes to Apple's liquid-damage policies for iPods, which may indicate some good news for iPod owners.

Apple's mobile devices come with small Liquid Contact Indicator (LCI) patches that react and change color when in contact with water. Apple uses the color change to determine whether a device has been submerged in water before honoring warranty claims for … Read more

Pentax has leaped to a commanding lead over many rivals when it comes to image sensor performance with its latest high-end SLR, the K-5.

The Pentax K-5 scored 82 on a new update of the DxOMark tests, which rate various performance attributes of a camera's image sensor.

That is a notable sixth-place ranking of all the cameras on DxO Labs' list, especially because the top 5 cameras are pro models costing thousands of dollars more than the K-5. The result came, in large measure, from the K-5 sensor's excellent dynamic range, a measure of its ability to capture details in both bright and dark areas of an image.

The K-5's Sony-built sensor spans a notable range of 14.1 exposure values at ISO 80, trouncing direct rivals such as the 11.7 of Canon's 7D and 12.2 of Nikon's older D300s. That score is all the more notable given that the K-5 even outscores some cameras with larger full-frame sensors.

However, it's clear that there is plenty of new competition coming. Nikon's new D7000, for example, has a dynamic range of 13.9 and largely matches the K-5 through much of its ISO range. Notably, the sensor in Nikon's cheaper D7000 scores 80 on DxO's tests. Those tests, it should be noted, only measure the sensor, not countless other important camera details such as price, autofocus, lens and accessory selection, durability, performance, and user interface.

Pentax's 16.3-megapixel, $1,600 flagship camera also will face a new range of full-frame rivals for those willing to pay a significantly higher price. Canon's 5D Mark II, Nikon's D700, and Sony's A850 are relatively elderly, and it will be a surprise if their successors don't feature sensors with compelling, new image quality at their heart.

For those who want to go farther up the product pecking order, Pentax has a different answer than full-frame SLRs, whose sensors are the size of a frame of 35mm film from the the bygone days of analog cameras. Instead, Pentax is selling its medium-format 645D camera, initially in Japan but also in Europe and the United States by the end of the year. Its sensor measures 44x33mm, compared with 36x24mm for full-frame sensors and 23.7x15.7mm for Pentax's K-5. Larger sensors have greater light-gathering abilities, helping in particular in low-light situations, but cost much more to manufacture and require bulkier lenses and camera bodies.… Read more

The partially transparent mirror in Sony's SLT (single-lens translucent) cameras offers some interesting features, but what hasn't been clear is the toll it takes on image quality.

Until now.

DxO Labs released today sensor test results for Sony's SLT-A33 and A55 and found that the mirror soaks up about one-third of an F-stop's worth of light.

This means a shot that otherwise could be taken at a shutter speed of 1/200th of a second would have be slowed down to 1/160th to get the same amount of light on an SLT camera, for example--or, holding other factors unchanged, that ISO sensitivity in dim conditions would have to be increased from 1,600 to 2,000, with the commensurate increase in noise.

The DxOMark sensor tests also found that A55's new 16-megapixel sensor is very competitive, tying the Nikon D90's score of 73 on the test. The A33 scores 70.

DxO Labs made the measurements by comparing the results from the A33 with the compact NEX-5, which uses the same sensor but lacks the partially translucent mirror arrangement.

That type of mirror, also called a pellicle mirror, lets the SLT camera line perform some neat tricks--autofocus can be continuously engaged, which allows the A33 to shoot 7 frames per second and the A55 to shoot 10 frames per second. With a pellicle mirror, autofocus works when shooting video, too.

Sony is preparing a new higher-end SLT model that's set to debut within a year. … Read more
