Precision alignment method and apparatus for cmos image sensors

PURPOSE: A method and an apparatus for accurately aligning a CMOS image sensor are provided to increase resolution by using a digital radiation image system. CONSTITUTION: A vision inspection apparatus performs a vision inspection process. The inspection process is performed on CMOS(Complementary Metal Oxide Semiconductor) image sensors(c1,c2). The vision inspection apparatus measures a distance to obtain a measurement value. The distance is from the edge of each pixel array of the CMOS image sensor to the cutting plane. A control part determines whether the CMOS image sensor is aligned or not.
