Abstract
The present disclosure relates to a computer implemented method and system for obtaining an image sensor exposure setting for use in capturing an image using a main flash. The method comprises the steps of obtaining first pre-image data related to a first pre-image captured using a predetermined first image sensor pre-image exposure setting, wherein the first pre-image is captured while emitting a flash of a predetermined first pre-flash energy; obtaining second pre-image data related to a second pre-image captured using a predetermined second image sensor pre-image exposure setting, wherein the second pre-image is captured while emitting a flash of a predetermined second pre-flash energy different than the first pre-flash energy; determining a flash effected area in the second pre-image in which a predetermined ratio of the image sensor pixel values have changed from the first pre-image; and determining the image sensor exposure setting for use in capturing the image based on the first and the second set of image senor pixel values in the flash affected area, the predetermined first and second image sensor pre-image exposure setting and a relation between a predetermined main flash energy, the energy of the predetermined first pre-flash and the energy of the predetermined second pre-flash, respectively.
