PROBLEM TO BE SOLVED: To eliminate fixed pattern noise that occurs in an imaging device of an electronic camera with high accuracy even though fluctuations of an environment are large in an imaging mode. SOLUTION: Noise data are acquired both before and after imaging an object, and correction processing of the fixed pattern noise is also performed on the basis of the two pieces of noise data. As a result, it is possible to eliminate the fixed pattern noise with high accuracy. |
