ABSTRACT:
Input from a user is received, to take a picture. A camera flash is signaled to produce multiple flash pulses during a single shutter cycle of the picture. The amplitudes of at least two of the flash pulses are different relative to each other. The picture is stored, including in its metadata information that describes the variable amplitude of the flash pulses that illuminated the scene when taking the picture. The information describing the variable amplitude of the flash pulses is used to deblur the picture. Other embodiments are also described and claimed.
