Motion compensation is one technique for frame rate conversion and is generally accepted as the best approach to give a smooth and continuous quality output. Motion compensation focuses on analysing motion within the input sequence of frames and estimating where objects would appear in newly created frames.
A typical motion compensated system may use phase correlation as an initial analysis stage, which can be further processed to provide information about the distance and direction of movement of objects in the scene. Assignment of motion vectors against image objects is a highly specialised area and quality of results are subject to the algorithms applied.
InSync Technology are at the forefront of motion compensated frame rate conversion, have many patents in this area and have developed numerous hardware and software solutions – based on this technology.
