Mobile phone-maker Motorola said Wednesday it had purchased facial recognition firm Viewdle for an undisclosed amount.
"Motorola Mobility today announced that it has acquired Viewdle, a leading imaging and gesture recognition company," Motorola said in a statement.
"Motorola and Viewdle have an existing commercial agreement and have been collaborating for some time," it added.
The Silicon Valley-based Viewdle produces applications for photo management, gaming, networking and marketing, and has operations in Europe and South America, according to its website.
Motorola was purchased by Internet giant Google for $12.5 billion last year.
