Nokia introduced its latest "PureView" branding on its Lumia 920 earlier today, and alongside the announcement the company released some promotional materials to demonstrate the functionality. We spotted a slight issue with the ads though: Nokia faked them. The opening segment of one particular ad showed a young man and woman riding bikes, designed to show off the capabilities of Nokia's optical image stabilization (OIS). However, we noticed a reflection that revealed the footage wasn't shot on a Lumia 920, but a regular camera inside a white van.

Nokia admitted the slip up to us earlier, but the company has now published a full public apology. In a blog post entitled "an apology is due," Nokia spokesperson Heidi Lemmetyinen admits that the company "produced a video that simulates what we will be able to deliver with OIS." Responding to criticism that the company should have identified its representation of OIS, Lemmetyinen reveals that the video "was not shot with a Lumia 920," confirming our original suspicions. "We apologize for the confusion we created."

To rectify the issue, Nokia has posted a new video to its YouTube channel — lacking any bikes or vans — which shows off the real difference between non-OIS and Nokia's Lumia 920 PureView. Embedded below, the video shows a smartphone without OIS on the left and the Lumia 920 on the right. "The difference is apparent," says Nokia, and we'd agree that it's certainly going to make a difference when it debuts in Q4 this year.
