Automatic image stabilizing system by full-digital signal processing

An automatic image-stabilizing system for camcorders and VCRs utilizing only digital signal processing has been developed. New technologies for this system are (1) the BERP (band extract representative point) matching technique with a small-scale circuit, (2) an adaptive system control algorithm to discriminate moving objects, and (3) suppression of motion vectors due to noise. Calculations show that the motion vector detector requires only 11000 gates, the electronic zoom controller requires only 8500 gates, and only one 8-b field memory is required.<
