Abstract

Se describen un método de codificación/decodificación de imágenes y un dispositivo para el mismo. Específicamente, un método de codificación de imágenes puede comprender los pasos de: generar un bloque de transformación cuantificado realizando transformación y cuantificación en una señal residual de un bloque actual; dividir el bloque de transformación cuantificado en una pluralidad de grupos de coeficientes; determinar un primer orden de escaneo que representa el orden de escaneo entre los coeficientes de los grupos de coeficientes; y codificar por entropía los coeficientes del bloque de transformación cuantificado de acuerdo con el primer orden de escaneo, y un segundo orden de escaneo que representa el orden de escaneo entre la pluralidad de grupos de coeficientes.
