System and method for establishing an aggregate degree of brightness for each primary color to create a composite color digital image

   
   

A system and method for establishing an aggregate degree of brightness for each primary color to create a composite color digital image. One of a plurality of primary colors is selected. A color digital image is captured with a color digital camera. The aggregate degree of brightness for the selected primary color is determined. The determined aggregate degree of brightness for the selected primary color is compared with the desired degree of brightness for the selected primary color. If the determined aggregate degree of brightness is not within a tolerance band surrounding the desired degree of brightness, then an adjustment is made to an exposure time controller of the color digital camera. This process is repeated until the determined aggregate degree of brightness is within the tolerance band surrounding the desired degree of brightness. If the determined aggregate degree of brightness is within the tolerance band surrounding the desired degree of brightness, then photosite values for the selected primary color are copied into corresponding pixels in a buffer. The process is repeated for each remaining primary color.

Un sistema y un método para establecer un grado agregado de brillo para que cada color primario cree una imagen digital del color compuesto. Uno de una pluralidad de colores primarios se selecciona. Una imagen digital del color se captura con una cámara fotográfica digital del color. El grado agregado de brillo para el color primario seleccionado se determina. El grado agregado resuelto de brillo para el color primario seleccionado se compara con el grado deseado de brillo para el color primario seleccionado. Si el grado agregado resuelto de brillo no está dentro de una venda de la tolerancia que rodea el grado deseado de brillo, entonces un ajuste se hace a un regulador del tiempo de la exposición de la cámara fotográfica digital del color. Se repite este proceso hasta que el grado agregado resuelto de brillo está dentro de la venda de la tolerancia que rodea el grado deseado de brillo. Si el grado agregado resuelto de brillo está dentro de la venda de la tolerancia que rodea el grado deseado de brillo, después los valores del photosite para el color primario seleccionado se copian en los pixeles correspondientes en un almacenador intermediario. El proceso se repite para cada color primario restante.
