Motorola Mobility officially revealed on Thursday that it has acquired the gesture and imaging company Viewdle. Viewdle also provides augmented reality support in its application and describes itself as a “best-in class computer vision technology showcases the power of your smartphone through camera-based innovations in augmented reality, device interaction, media management, gaming, + social networking.”

Neither Motorola Mobility nor Viewdle disclosed how much the phone maker paid for the software company, but TechCrunch estimates the acquisition cost Motorola between $30 million and $45 million.

“Motorola Mobility today announced that it has acquired Viewdle, a leading imaging and gesture recognition company,” the company said in an official statement to TechCrunch. “Motorola and Viewdle have an existing commercial agreement and have been collaborating for some time. Terms of the transaction were not disclosed.”

We’re not sure where Motorola will use Viewdle’s software, but we’re guessing it’s going to pop-up in some of the company’s future Android smartphones in one way or another, and will more than likely be used for face identification in photos. Samsung, for example, already offers a competing option in its Galaxy S III and Note II.
