Abstract:
A system for recording an image as digital data comprises a photosensor array and a plenoptic set, including a main lens and a lenticular grating, to enable the photosensor array to obtain plenoptic image data from the sheet. A subset of the plenoptic image data is selected, such as according to a predetermined object distance, to obtain image data for a focused image. The subset of the plenoptic image can be selected after the scanning, so that prescanning of an unusual-shaped image-bearing object, such as an open book, is avoided.
