Abstract:
1. Image capturing device, comprising: an electronic image detector having a detecting surface, the detecting surface of the image detector includes pixels of predetermined size; and an optical projection system for projecting an object within a field of view onto the detecting surface, wherein the projection system is configured to project the object in a distorted way such that the projected image is expanded in a center region of the field of view and is compressed in a border region of the field of view, such that its point spread function in the border region of the field of view has a full width at half maximum greater than the size of corresponding pixels of the image detector and less than three times the size of corresponding pixels of the image detector, and its point spread function in the center region of the field of view has a full width at half maximum of less than the size of corresponding pixels of the image detector.
