With its new flagship device, the Lumia 920 smartphone, Nokia has focused much of the public's attention on the phone's new PureView camera technology, promoting it as the future of smartphone cameras -- turns out, that future is beyond Nokia's reach, too.

On the same day the company unveiled its Lumia 920 and 820 smartphones, meant to turn the sagging business around, Nokia found itself issuing an apology when tech bloggers noticed that they had faked a video that shows off the image stabilizer. Nokia has released a statement admitting to faking the benefits of its PureView technology in the promotional video.

The video, seen below, shows an attractive couple biking along a dock, a young curly-haired man recording a young woman in a red dress with his Lumia 920. The video then purports to show the shaky footage captured without Nokia's Optical Image Stabilization (OIS), part of the company's "PureView" technology -- and the level, even video that the technology enables.

Eagle-eyed bloggers spied the couple passing a parked car -- and the reflection in the window of the cameraman, in a white van, using a professional camera to record the entire event.

In a blog post entitled "an apology is due," Nokia officially came clean about faking the video.

"In an effort to demonstrate the benefits of optical image stabilization (which eliminates blurry images and improves pictures shot in low light conditions), we produced a video that simulates what we will be able to deliver with OIS," wrote Nokia spokeswoman Heidi Lemmetyinen.

"We should have posted a disclaimer stating this was a representation of OIS only. This was not shot with a Lumia 920," she added. "We apologize for the confusion we created."

One highlights of Nokia's Lumia 920, Jo Harlow, head of Nokia's mobile phones business, says PureView can capture 5-10 times the amount of light of any competitors' smartphone cameras via a "floating lens technology that surpasses the optical image stabilization system of most digital SLRs," according to PC Mag. The Lumia 920 includes an 8.7-megapixel rear-facing camera and full 1080p HD video capture at 30 fps. There is a 1.3-megapixel front-facing camera with 720p HD video capture.

"The technology reacts to the minute movements in your hand to balance the lens, so the shutter can stay open longer, and more light means brighter, clearer images without flash, even indoors and at night," Harlow said. "The Nokia Lumia 920 also replaces your HD camcorder because another benefit of this floating lens technology is that the lens is stabilized for taking smooth and professional-looking video."

Nokia posted a new video to its blog showing actual footage from the new phone. That's the story the Finnish company is sticking to right now, at least.
