Abstract

Se provee un metodo de prediccion de imagen en movimiento para permitir que una cantidad de calculo y una capacidad de almacenamiento sean reducidas en una prediccion acerca de una imagen en movimiento mediante procesamiento de escalamiento. Un metodo para predecir el valor P del tiempo T a partir del valor P0 del tiempo P0 y el valor de P1 del tiempo P1 incluye un paso de juzgar si es posible generar un valor predictivo con un numero significativo predeterminado de bits mediante escalonamiento con el uso del tiempo T0, T1 y T (Paso S90); un paso para predecir el valor P a partir de los valores P0 y P1 mediante escalamiento con el uso de un tiempo T0, T1 y T cuando es posible generar un valor predictivo con el numero significativo predeterminado de bits (Paso S92); y un paso para predecir el valor de P a partir de los valore P0 y P1 sin usar el tiempo T0, T1 y T cuando es imposible generar un valor predictivo con el numero significativo predeterminado de bits (Paso S91).
