Abstract
dispositivo de processamento de imagem, método de processamento de imagem, e, programa. são divulgados um dispositivo de processamento de imagem, método de processamento de imagem, e programa que pode reduzir a quantidade de processamento requerido para um rot e um dct ou um dct inversa e um rot inverso. aplicando quantizaçãqo inversa da informação de imagem obtida decodificando uma imagem codificada, componentes de baixa frequência da informaçãode imagem mencionada, obtida via uma primeira unidade de transformação ortogonal, e componentes de alta de frequência da informação de imagem mencionada, obtida via uma segunda unidade de transformação ortogonal, são obtidos. os componentes de alta frequência mencionados, são maiores em frequência do que os componentes de baixa frequência. os componentes de baixa frequência e componentes de alta frequência mencionados são então submetidos uma transformação ortogonal inversa via uma técnica similar. esta tecnologia pode ser aplicada, por exemplo, para codificação e decodificação de imagem.
