Abstract

"APARELHO E MéTODO DE PROCESSAMENTO DE IMAGEM, E, PROGRAMA DE COMPUTADOR". São providos um aparelho e método para executar eficientemente uma correção de cor falsa, tal como franja púrpura ou semelhante, causada por aberração cromática e para gerar e emitir dados de imagem de alta qualidade. Pixéis de não graduação branca são detectados a partir de dados de imagem e uma área de detecção de pixel de cor falsa é estabelecida em torno dos pixéis de não graduação branca detectados. Na área estabelecida, pixéis possuindo cor correspondente à cor falsa tal como franja púrpura são detectados e os pixéis detectados são especificados como pixéis de cor falsa. Os pixéis de cor falsa especificados são corrigidos baseados em um valor dos pixéis periféricos. Esta configuração permite um detecção eficiente de uma área de cor falsa da franja púrpura ou semelhante ocorrendo na vizinhança dos pixéis de não graduação branca, e também permite uma correção de valor de pixel parcial, de forma a permitir a produção e emissão de dados de imagem de alta qualidade sem afetar a imagem inteira.
