Abstract

''dispositivo de ampliação de imagens, programa de ampliação de imagens e aparelho de exibição'' a presente invenção refere-se a um dispositivo de ampliação de imagens que inclui: um filtro de ampliação de imagens (1) que gera uma primeira imagem ampliada ampliando-se uma imagem de entrada; uma porção de transformada de ondaleta (2) que executa uma transformada de ondaleta na primeira imagem ampliada; porções de processamento de ganhos (3,4 e 5) que executam processamento de ganho em componentes de sub-banda incluindo-se componentes de alta frequência produzidos a partir da porção de transformada de ondaleta (2); e uma porção de transformada inversa de ondaleta (6) que considera, como uma imagem de transformada de ondaleta, a imagem de entrada e os componentes de sub-banda incluindo-se os componentes de alta-frequência que são produzidos a partir da porção de processamento de ganho e nos quais o processamento de ganho tem sido executado, e que gera uma segunda imagem ampliada executando-se uma transformada inversa de ondaleta.
