A method and apparatus serves for converting a low resolution first image to a high resolution second image. The apparatus is comprising a light sensor (1, 19) for receiving incident light radiated from a scene. The light sensor has a number of cells, each defining a predetermined area, and is arranged for cyclically scanning the low resolution first image a number of times while at least one driver (21, 33, 39, 40) is moving the light sensor an identical number of times in at least one direction. For each step the light sensor is moved a distance corresponding to the extend of the area covered by the cell in the direction of movement while the total distance covered corresponds to the extend of the cell in said direction. Thereby a number of subareas are defined. A computer (23, 35) serves for establishing a representation of the high resolution second image by calculating the representation of the received incident light from the scene at each subarea by means of a soft ware program. Thereby is obtained a higher resolution and a better image quality than hitherto known.
