The invention refers to a device, a method and a computer program product for extracting motion information from a sequence of video frames. Existing solutions for extracting motion information from sequence of video frames need a massive computing power which make it difficult and expensive to implement a real-time system. It is therefore an object of the invention to simplify such a device and to provide a real-time embedded system. It is suggested to provide a device comprising a digital video camera 1. The video camera 1 includes a processing unit 3 for processing video frames grabbed by the video camera 1. The processing uses a 3D recursive search block matching algorithm to extract the motion information from the video frames. The device can be used for traffic surveillance applications, e.g. for determining the speed of vehicles on the streets and roads.
