Abstract

"FOTODETECTOR, PROCESSO DE FOTODETECçãO E MEIO DE ARMAZENAGEM". A presente invenção refere-se a um fotodetector capaz de realizar uma medição mais acurada, um processo de fotodetecção, um programa e um meio de armazenagem são proporcionados. O fotodetector de acordo com a presente invenção mede uma característica de luminância de uma cor específica de uma unidade de exibição, sob uma luz de iluminação específica. De acordo com o fotodetector da presente invenção, os componentes de cor da luz de iluminação e componentes de cor da luz específica são separados uns dos outros por meio de um separador de luz 60f. Então, usando um operador Md para a unidade de exibição, os componentes de cor da cor específica assim separados são convertidos de LMS para XYZ, por meio de convesor 60g para a unidade de exibição. Ainda, usando um operador Mi para iluminação, os componentes de cor da luz de iluminação assim separados são convertidos de LMS para XYZ, por meio de um conversor 60h para iluminação. Assim, uma vez que o operador para a unidade de exibição e operador para iluminação são usados cada qual independentemente para a conversão de RGB para LMS, mesmo uma cor superposta de ambas, saída da unidade de exibição e luz de iluminação, pode ser medida com uma precisão mais acurada.
