PROBLEM TO BE SOLVED: To solve the following problem: when removing offset FPN in a conventional manner, synchronous noise cannot be removed, and vertical-stripe noise appears in a photographic image. SOLUTION: Provided are an imaging element having a plurality of unit pixels disposed in a two-dimensional shape (row, column); an offset data producing part to compute an offset component between columns from a dark signal output from the imaging element; a synchronous noise storage part to store synchronous noise data; and a correction data producing part to produce correction data by operating the offset data generated by the offset data producing part and the synchronous noise data stored in the synchronous noise storage part.
