Abstract
A displacement detection circuit () configured to implement a displacement detection method () for a pointing device () having at least one pixel array (). The displacement detection circuit () includes at least one main calculator (), at least one auxiliary calculator () at least one comparator () and at least one motion detector (). The main calculator () is configured to calculate at least one main average () corresponding to the average of the at least one pixel array (), which is compared to at least one auxiliary average () of the at least one auxiliary calculator (). According to the result of the comparison, the at least one motion detector () indicates at least one direction () of displacement of the pointing device ().
