Abstract

resumo patente de invenção: "método de codificação, método de decodificação, dispositivo de codificação e dispositivo de decodificação". a presente invenção refere-se a um método de codificação, de acordo com uma modalidade, que inclui uma etapa de derivação e uma etapa de codificação. a etapa de acionamento deriva um primeiro valor de referência que é um valor de referência de um fator de ponderação com base na precisão de ponto fixo que representa uma irregularidade do fator de ponderação que é usado para fazer uma previsão compensada por movimento de uma mudança em um valor de pixel pela multiplicação de uma imagem de referência pelo fator de ponderação. a etapa de codificação codifica um primeiro valor de diferença que é um valor de diferença entre o fator de ponderação e o primeiro valor de referência. o fator de ponderação é incluído em uma faixa de precisão de bit predeterminada que tem o primeiro valor de referência no centro aproximado. 20618641v1
