Abstract

The invention refers to a flash light compensation system and corresponding method for digital camera systems, wherein a luminance compensation is carried out on an image of a scene () picked-up by an image sensor (), on the basis of a respective intensity field measured by a plurality of sensors (), when the scene is illuminated by flash light emitted by a flash device (). Depending upon the output signals of the plurality of sensors a depth field of the scene is estimated, and this estimation provides a basis for the luminance adjustment on the scene picked up as an image while illuminated by the flash device. The system and method is suitable for effectively reducing the problem of unevenly distributed lighting on a picked-up image of the scene.
