IMAGE SENSOR AND A METHOD FOR COMPENSATING OPTICAL AXIS SHIFT USING THE SAME, CAPABLE OF SAVING FACILITY INVESTMENT COSTS DUE TO TOLERANCE MANAGEMENT

摘要

PURPOSE: An image sensor and a method for compensating optical axis shift using the same are provided to make a light receiving part of the image sensor larger than a reference area, and estimate a shift amount of an optical axis to correct a coordinate output value of an image on the light receiving part, thereby correcting shift about the optical axis without adjustment of assembling tolerance and mechanical movement of a lens.;CONSTITUTION: An image sensor(100) includes a substrate(101), a real light receiving area(103), a correction light receiving area(105) and a pad(104). Image signal conversion of light which deviates from a reference light receiving area(102) and then is received is performed by correcting a shift amount of an optical axis about light received in the real light receiving area. The pad is for electric connection with an external device through wire bonding or flip chip bonding in the outside of the real light receiving area.;COPYRIGHT KIPO 2010
