Abstract

Un dispositivo de codificación para codificar una corriente de bits que incluye una trama de imagen puede incluir un codificador configurado para determinar una posición de un pixel que tiene un último coeficiente diferente de cero en un bloque de coeficiente de conversión que constituye la trama de imagen con referencia a un pixel predeterminado del bloque de coeficiente de conversión, identificar un sub-bloque que incluye el último coeficiente diferente de cero, entre una pluralidad de sub-bloques que constituyen el bloque de coeficiente de conversión, convertir una posición del último coeficiente diferente de cero determinado con referencia al pixel predeterminado del bloque de coeficiente de conversión en una posición con referencia a un pixel predeterminado del sub-bloque identificado y codificar el sub-bloque que incluye el último coeficiente diferente de cero y la posición convertida del último coeficiente diferente de cero.
