Abstract

"APARELHO E MéTODO PARA CORRIGIR DISTORçãO DE IMAGEM E MOSTRADOR DE IMAGEM USANDO OS MESMOS". Trata-se dé um aparelho e de um método para corrigir uma imagem distorcida que é capaz de corrigir uma distorção ótica de uma imagem e a mal convergência por pré-deformar uma imagem informada sem utilizar um enrolamento de convergência e um apresentado de imagem utilizando o mesmo. O aparelho para corrigir uma distorção de imagem para um mostrador de imagem no qual um sinal de imagem é informado para exibir uma imagem em uma tela e uma distorção da imagem é corrigida, inclui um gerador de imagem de referência para gerar uma imagem de referência pré-deteminada, uma câmara para informar a imagem de referência e fotografar uma imagem emitida na tela; e uma unidade de extração de informação de distorção para comparar a imagem fotografada emitida a partir da câmara com a imagem de referência emitida a partir do gerador de imagem de referência e gerar a informação de correção de distorção para corrigir uma distorção da imagem fotografada no caso em que a imagem foi distorcida.
