Abstract

um dispositivo de captura de imagem inclui um sensor de imagem tendo diodos para detectar a luz de uma cena alvo, um conjunto de filtros de cor disposto acima dos diodos e incluindo filtros de cor cada posicionado sobre um dos diodos, único diodo microlentes posicionado acima alguns filtros de cor dispostos em um padrão bayer, e microlentes de multi-diodo cada posicionada acima de pelo menos dois filtros de cor adjacente que passam os mesmos comprimentos de onda de luz para correspondentes diodos adjacentes abaixo dos filtros de cor multi-diodo, cada microlente formada de modo que a luz incidente em uma primeira direção é coletado de um dos diodos adjacentes e a luz incidente em uma segunda direção é coletada em outra de diodos adjacentes. um processador de sinal de imagem do dispositivo de captura de imagem pode realizar detecção de fase autofoco usando sinais recebidos dos diodos adjacente e pode interpolar os valores de cor para os diodos adjacentes
