Abstract:
In a particular embodiment, a method is disclosed that includes determining at least one ambient exposure parameter using an ambient illumination, the at least one ambient exposure parameter including a first sensitivity parameter of an autoexposure controller using the ambient illumination. The method includes determining at least one low-illumination parameter using a first lamp level, the at least one low-illumination parameter including a second sensitivity parameter of the autoexposure controller using the first lamp level, where the autoexposure controller is configured to operate according to at least one high-illumination parameter based on the at least one ambient exposure parameter and the at least one low-illumination parameter. The method further includes performing an image capture operation using a second lamp level that is brighter than the first lamp level, where the at least one high-illumination parameter includes a third sensitivity parameter.
