ABSTRACT:
An image processing system and method for processing a source digital image with a first energy sensitivity parameter value and including first pixels of first pixel values into a target digital image with a selected second energy sensitivity parameter value and including second pixels of second pixel values, for enabling a photographer to adjust resolution and sensitivity of a digital image to correspond to the light sensitivity of a specific photographic film. Thus, the photographer can use a light meter to indicate pairs of exposure time and diaphragm settings for the electronic camera that will ensure a correct exposure of the digital image when the light meter is set to indicate correct pairs of exposure time and diaphragm settings for a camera.
