Abstract
"APARELHO DE INTERPOLAçãO DE IMAGEM". é provido um aparelho de interpolação de imagem para interpolação de um sinal de imagem de entrada que tem uma primeira resolução para um sinal de imagem de saída que tem uma segunda resolução de acordo com uma relação de conversão de resolução predeterminada, incluindo: um determinador de freq³ência que detecta uma variação em uma freq³ência do sinal de imagem de entrada para a determinação de um domínio de freq³ência correspondente ao sinal de imagem de entrada; um controlador que calcula posições de interpolação do sinal de imagem de entrada de acordo com a relação de conversão de resolução predeterminada; um armazenamento de coeficiente que armazena coeficientes de interpolação correspondentes às posições de interpolação; um filtro de interpolação que recebe os coeficientes de interpolação do armazenamento de coeficiente para interpolação do sinal de imagem de entrada; e um corretor de valor de interpolação que corrige o sinal de imagem de saída para o sinal de imagem de entrada extraído do filtro de interpolação com base na informação quanto ao domínio de freq³ência determinado pelo determinador de freq³ência.
