Google Inc's online video service YouTube said on Tuesday it has bought video technology company Green Parrot Pictures for an undisclosed sum.

The Dublin, Ireland-based company specializes in providing intellectual licensing and high quality picture manipulation technology. Its video improvement technology has been used in Hollywood movies like Lord of the Rings, SpiderMan and King Kong, among others.

It was founded in 2004 by Chief Executive Anil Kokaram, an associate professor at Trinity College in Dublin. Kokaram and his team will be moving to California in coming months.

Google declined to disclose terms of the deal.
