Abstract:
1. A method for converting a low resolution first image produced by a light sensor for receiving incident light radiated from a scene to a high resolution second image, whereby the light sensor is constructed as an array or matrix having a number of cells with each cell defining a predetermined area, which method comprises: cyclically scanning the first image a number of times; simultaneously moving the light sensor with the scanning stepwise an identical number of times relative to the light radiating scene in at least one direction thereby defining a number of subareas, such that the total distance covered during movement of the light sensor corresponds to the extent of the cell or to the extent of the cell plus a distance defined by or to a neighbor cell in the at least one movement direction, and establishing a representation of the high-resolution second image by calculating the representation of the received incident light from the scene at each subarea; wherein the light sensor is moved a distance in each step corresponding to the extent of the area covered by the cell in the direction of movement or to the extent of the area covered by the cell in the direction of movement plus a distance defined by or to the neighbor cell in the direction of movement, divided by the number of scanning times.
