Abstract
A system, method, and computer program product are provided for simultaneously capturing flash and ambient illuminated images. In use, an ambient sample is stored based on an electrical signal from a photodiode of an image sensor. Also, a flash sample is stored based on the electrical signal from the photodiode of the image sensor. Further, a first value is output based on the ambient sample, and a second value is output based on the flash sample, for generating at least one image. Finally, at least one of the first value and the second value is amplified utilizing two or more gains.
