Abstract
Se proporciona tecnología para mejorar la eficiencia de la codificación mediante la realización de una división de bloques adecuada para la codificación y decodificación de imágenes. Un dispositivo incluye una unidad de almacenamiento de información de codificación configurada para llenar todos los candidatos basados en el historial en una lista de candidatos de predictor de vector de movimiento basados en el historial con al menos un vector de movimiento predeterminado y un índice de referencia; una unidad de generación de lista de candidatos de fusión configurada para generar una lista de candidatos de fusión que incluye al menos un vector de movimiento y un índice de referencia de un bloque adyacente a un bloque objetivo de codificación como candidato de fusión; una unidad de adición de candidato de fusión basado en el historial configurada para agregar un candidato basado en el historial incluido en la lista de candidatos de predictor de vector de movimiento basados en el historial a la lista de candidatos de fusión como un candidato de fusión y generar una segunda lista de candidatos de fusión; y una unidad de selección de candidato de fusión configurada para seleccionar un candidato de fusión de la segunda lista de candidatos de fusión como un candidato de fusión de selección, en donde la unidad de almacenamiento de información de codificación agrega el candidato de fusión de selección a la lista de candidatos de predictor de vector de movimiento basados en el historial como un candidato basado en el historial y genera la lista de candidatos de predictor de vector de movimiento basados en el historial.
