Abstract
APARELHO DE EXIBIÇÃO DE IMAGEM E MÉTODO PARA CONTROLE DE APARELHO DE EXIBIÇÃO DE IMAGEM. Um aparelho de exibição de imagem inclui: um primeiro dispositivo de modulação de luz que inclui uma pluralidade de pixels de exibição e modula a luz de entrada com base na primeira informação de imagem; uma unidade de iluminação que inclui uma pluralidade de elementos de ajuste de luz e emite luz ajustada para o primeiro dispositivo de modulação de luz; uma unidade de armazenamento de distribuição de iluminação que armazena uma faixa de iluminação em que a luz emitida a partir dos elementos de ajuste de luz ilumina os pixels do mostrador do primeiro dispositivo de modulação de luz; e uma unidade de decisão de informação de ajuste de luz que decide a informação de ajuste de luz para controlar os elementos de ajuste de luz da unidade de iluminação com base em uma quantidade característica da primeira informação de imagem correspondente aos pixels do mostrador da faixa de iluminação armazenada na unidade de armazenamento de distribuição de iluminação.
