Abstract

DISPOSITIVO E METODO DE PROCESSAMENTO DE IMAGEM. Em uma unidade de compensação/prognóstico de movimento (32), quando dados de imagem de referência são usados para realizar compensação de movimento e gerar dados de imagem prognosticados nas bases dos vetores de movimento detectados por detecção de movimento, uma unidade de controle de compensação (3231) comuta coeficientes de filtro fornecidos para uma unidade de filtro (3233) a partir de uma tabela de coeficientes (3232) em resposta ao processamento de filtro de malha nos dados de imagem de referência usados para a geração dos dados de imagem prognosticada. Por exemplo, quando processamento de filtro de malha não é realizado, os dados de referência sofre processamento de filtro usando uma característica de filtro tendo alta intensidade de redução de ruído. Assim sendo, dados de imagem prognosticados tendo pequeno ruído podem ser gerados, e deterioração da qualidade das imagens prognosticadas e redução de eficiência de compressão podem ser inibidos.
