Troubled phone maker Nokia this morning announced that it has completed its purchase of all technologies and intellectual property from Swedish imaging software firm Scalado, originally announced on June 14.

The completion is way ahead of schedule – Nokia had said it expected the acquisition to close during the third quarter of 2012 when it was announced.

The company says the acquired assets will help it bring “outstanding imaging experiences” to its Lumia line of smartphones. Nokia announced last week that it has sold 4 million Lumia phones globally to date.

The company says the Lund site in Sweden will become a crucial place for its imaging software for smartphones, in addition to its existing locations in Espoo and Tampere, Finland. As part of the deal, approximately 50 imaging specialists from Scalado were transferred to Nokia.

On its website, Scalado says it owned more than 50 patents and patent-pending imaging technologies, which are now in Nokia’s hands.

Nokia doesn’t make any mention of what it plans to do with the acquired intellectual property, but has earlier stated that equally troubled rival Research In Motion will still be allowed to use Scalado software in BlackBerry 10.

Scalado’s technologies enable the mobile capturing, viewing and editing of high-res still images with minimal battery and memory consumption. Its solutions are licensed by no just RIM but by the top five mobile phone manufacturers, top 10 ISP/Sensor companies and most leading platform providers, the Swedish firm claims.

Scalado’s imaging technology is said to be on more than 1 billion devices.

Nokia refers to this Conversations blog post for more information. It reads:

Why should Nokia fans be excited?

Well: the precise details of the deal are secret. And will probably remain so until they emerge into products.

Okay then.
