METHOD OF MODELING INTEGRATED NOISE IN IMAGE SENSOR AND METHOD OF REDUCING NOISE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method of modeling integrated noise in an image sensor, and to provide a method of reducing noise using the same. SOLUTION: A plurality of noise models including a dark-current noise model, a shot noise model and a fixed-pattern noise model in a Bayer domain signal (BS) provided from an image sensor 100 are each set in a modeling unit (320) and an integrated noise level (SINT) is determined based on the plurality of set noise models. Noise filtering can be efficiently performed by accurate noise modeling reflected with various noise properties in the Bayer domain. COPYRIGHT: (C)2011,JPO&INPIT
