  • Image displacement detection method
    Patent number: 8300888
    Abstract: The present invention provides an image displacement detection method, which employs the center of a 1st frame as a starting point, and the previous image displacement vector or the inversed direction displacement of the adjusted previous image displacement vector as the image matching reference block; next, proceeds the matching with the 2nd frame to calculate the image displacement vector between the 1st frame and the 2nd frame. Thus, the method of the present invention can relatively increase about twice the maximum tracking speed of the sensor.
