Abstract

Se proporciona tecnología para mejorar la eficiencia de codificación mediante la realización de una división de bloques adecuada para la codificación y decodificación de imagen. Un dispositivo incluye una unidad de almacenamiento de información de codificación configurada para agregar la información de predicción inter utilizada en la predicción inter a una lista de candidatos a predictor de vector de movimiento basados en el historial, una unidad de derivación de candidatos a predictor de vector de movimiento basada en el historial configurada para derivar candidatos a predictor de vector de movimiento basados en el historial de la lista de candidatos a predictor de vector de movimiento basados en el historial, y una unidad de derivación de candidatos de fusión basados en el historial configurada para derivar candidatos de fusión basados en el historial de la lista de candidatos a predictor de vector de movimiento basados en el historial, en donde la unidad de derivación de los candidato a predictor de vector de movimiento basados en el historial y la unidad de derivación de candidatos de fusión basados en el historial establece candidatos incluidos en la lista de candidatos a predictor de vector de movimiento basados en el historial como los candidatos a predictor de vector de movimiento basados en el historial o los candidatos de fusión basados en el historial con referencia a los candidatos incluidos en la lista de candidatos a predictor de vector de movimiento basados en el historial en órdenes diferentes entre sí.Technology is provided to improve encoding efficiency by performing proper block division for image encoding and decoding. A device includes an encoding information storage unit configured to add the inter prediction information used in inter prediction to a list of motion vector predictor candidates based on history, a vector predictor candidate derivation unit history-based motion predictor configured to derive history-based motion vector predictor candidates from the history-based motion vector predictor candidate list, and a configured history-based fusion candidate derivation unit to derive history-based fusion candidates from the history-based motion vector predictor candidate list, wherein the derivation unit of the history-based motion vector predictor candidate and the derivation unit of merger candidates based on history establishes candidates included in the list list of history-based motion vector predictor candidates such as history-based motion vector predictor candidates or history-based fusion candidates with reference to candidates included in the vector predictor candidate list of movement based on history in different orders from each other.
