Abstract

Se describe un dispositivo de codificacion de imagenes (300) que incluye una seccion de deteccion (302) y una seccion de compensacion de movimiento (303). Entre grupos de bloques que constituyen un macrobloque decodificado que corresponde a un macrobloque de objetos de decodificacion, de acuerdo con el vector de movimiento del bloque localizado en una segunda esquina del macrobloque decodificado, la seccion de deteccion (302) selecciona un metodo de calculo de vectores de movimiento que corresponde a un bloque de objetos de compensacion de movimiento, calculando un vector de movimiento por el metodo de calculo seleccionado, y haciendolo como un candidato de deteccion de vectores de movimiento. De acuerdo con el vector de movimiento detectado, la seccion de compensacion de movimiento (303) crea una imagen predicha del bloque de objetos de compensacion de movimiento.
