Abstract

CORREÇÃO DE PIXELS MATIZADOS DE CORES CAPTURADOS EM CONDIÇÕES DE BAIXA LUMINOSIDADE. Os aspectos da presente descrição referem-se à correção em encadeamentos de processamento de imagem. Um método exemplar pode incluir receber primeiros dados de imagem correspondendo a dados de luminância de referência e dados de crominância de referência para cada um de uma pluralidade de pixels, determinar que os primeiros dados de imagem correspondem a uma imagem bruta capturada em um ambiente escuro, gerar segundos dados de imagem realizando uma ou mais operações de mapeamento de tons nos primeiros dados de imagem, os segundos dados de imagem correspondem a dados de luminância atuais e dados de crominância atuais para cada um de uma pluralidade de pixels, e gerar dados de imagem de saída. Para cada pixel da pluralidade de pixels, os dados de saída podem incluir um valor de luminância de saída de um pixel correspondente dos dados de luminância atuais, e os valores de crominância do pixel correspondente a partir de um dado selecionado dos dados de crominância de referência e dos dados de crominância atuais, a seleção com base pelo menos em parte nos dados de crominância de referência e nos dados de crominância atuais.
