Abstract

"dispositivo e método de processamento de imagem, e, programa" são divulgados um dispositivo de processamento de imagem e método e um programa que são capazes de mais eficientemente efetuar codificação e decodificação tendo alta eficiência de codificação. uma unidade de classificação de elemento mínimo de imagem (151) classifica os valores de elemento mínimo de imagem de uma imagem de pré-filtragem decodificada que foi fornecida a partir de uma unidade de cálculo (110). uma unidade de cálculo de coeficiente de filtro (112) calcula o coeficiente de filtro para as classes dos valores de elemento mínimo de imagem classificados. um filtro de desbloqueio forte (152), um filtro de desbloqueio fraco (153), e um filtro adaptativo (154) cada um efetua os respectivos processos de filtragem do mesmo nos valores de elemento mínimo de imagem fornecidos a partir da unidade de cálculo (110) usando o coeficiente de filtro fornecido a partir da unidade de cálculo de coeficiente de filtro (112). aplicação em um dispositivo de processamento de imagem, por exemplo, é possível.
