Abstract
One embodiment described relates to an optical displacement sensor for sensing movement of a data input device across a surface by detecting displacement of optical features in a succession of images of the surface. The sensor includes a detector having an array including a number (N) of sets of photosensitive elements, each set having a number (M) of photosensitive elements, where M is greater than two and not equal to four. Signals from each of the photosensitive elements in a set are electrically coupled or combined with corresponding photosensitive elements in other sets to produce a total of M independent group signals from M interlaced groups of photosensitive elements. Other embodiments are also described.
