Patent US 8,941,775

Systems, methods, and devices for obtaining a properly exposed strobe-illuminated image are provided. One method for doing so may include, for example, gathering image capture statistics during a first period when a strobe is not emitting light and during a second period when the strobe emits a preflash. These image capture statistics may include distinct image capture control statistics and luma values associated with the periods. Final image capture control statistics then may be determined based at least in part on the first luma value normalized to the first image capture control statistics and the second luma value normalized to the second image capture control statistics. Thereafter, the final image capture control statistics may be used to capture a properly exposed strobe-illuminated image when the strobe emits a main flash.
