1. A method for processing light data using light collected with an imaging arrangement including a main lens that focuses light to microlenses at a focal plane, and photosensors that include, for each microlens, a plurality of photosensors arranged to receive light directed by the microlens, the method comprising: using the photosensors to collect light that is directed by the microlenses, and to output light data characterizing the collected light; weighting the light data as a function of an optical characteristic of the imaging arrangement and a light ray path of the collected light through the main lens and microlenses, thereby providing weighted light data values; digitally processing the light data as a function of the weighted light values and the light ray path; and using the digitally processed light data to output image data in which at least a portion of the image data is corrected.
