METHOD FOR TWO DIMENSIONAL CHARGE MOVEMENT OF CCD SENSOR OR HYBRID SENSOR

摘要

A method for the two-dimensional movement of a charge in a CCD sensor or hybrid sensor is provided to guarantee more accurate compensation and quick response by breaking away from a method for compensating the mechanical tremor, and realize the charge movement in the two-dimensional 4 directions or 8 directions. A divided phase is formed within one unit pixel in the form of a square matrix of 3 X 3. An adjacent unit pixel has 9 divided phases(1Phi~9Phi) which have the square matrix structure of 3 X 3. The divided phases which are at the same location within a plurality of unit pixels are the same phase. The voltage of the same level is applied to the same phase. Therefore, 2 divided phases or 9 divided phases are turned on. When the voltage is applied, the voltage is not applied to the boundary between unit pixels. Charges within each unit pixel is not invaded the boundaries of each unit pixels. The number of charges to be stored is proportioned to the strength of the applied voltage and the area which the voltage influences.
