Abstract: La presente invención se refiere a un método y aparato para codificar una señal de video, y más específicamente, un vector de movimiento entre los puntos de vista se obtiene utilizando un valor de profundidad de un bloque de profundidad, que corresponde a un bloque de la textura actual, y se compensa una diferencia de iluminación. Al obtener el vector de movimiento entre los puntos de vista utilizando el valor de profundidad del bloque de profundidad, el cual corresponde al bloque de la textura actual, y compensar la diferencia de la iluminación, la presente invención puede obtener un valor de predicción exacto del bloque de la textura actual y por tanto aumenta la exactitud de la interpredicción entre los puntos de vista.

Abstract: Disclosed are a method for converting a frame format and an apparatus using the same. The method may include: decoding an encoded multiview video compression (MVC)-compatible frame using an MVC decoder; and converting the decoded MVC-compatible frame into an advanced 3D frame. Accordingly, a different frame format may be played by an existing image processing device.

Abstract: The method for deriving a temporal motion vector predictor according to the present invention comprises the steps of: selecting a reference picture for a current block; deciding a predictor block corresponding to a predetermined storage unit block, as a reference prediction unit for the current block, in the reference picture; and deriving the temporal motion vector predictor from motion information of the decided reference prediction unit. The present invention enhances image compression efficiency.
