Abstract: The present invention is related to an image sensor and to a method for operating such sensor. The sensor of the invention comprises a pair of butted sensor tiles, each sensor tile comprising a pixel array comprising a plurality of rows and columns of photosensitive pixels.By constructing first row groups using at least one imaginary row, a different center-to-center distance exists between the different row groups than that which is obtained in prior art devices. More in particular, the construction according to the present invention allows the center positions of the rows to lie on a regular grid thereby lowering the geometrical distortion of the resulting image.
