METHOD AND SYSTEM FOR COMPENSATING FIXED PATTERN NOISE FOR COMPENSATING FIXED PATTERN NOISE IN DIGITAL IMAGE WITHOUT USING EXTERNAL SHUTTER

摘要

PURPOSE: A method and system for compensating a fixed pattern noise are provided to compensate a fixed pattern noise in an acquired digital image without using an external shutter. CONSTITUTION: A method for compensating a fixed pattern noise in a digital image provides a nonvolatile memory, a processing device(4), correction frames and an image sensor(2). Fixed pattern noise data with respect to the image sensor is obtained using the correction frames. The obtained fixed pattern noise data is stored. Fixed pattern noise data with respect to each of acquired pictures is searched. The fixed pattern noise data is applied to each pixel of each of the acquired pictures in order to compensate the fixed pattern noise.
