Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an imaging apparatus, a correction value calculation method of the imaging apparatus, and an imaging method for calculating a gain correction value and an offset correction value with small capacity of memory, and correcting output values of a plurality of image pickup devices so as to be approximately the same for the same object. SOLUTION: Two images having different uniform luminance captured by an imaging part are stored in two memories P1, P2, respectively. When the correction value is calculated, the two images are read from the memories, the gain correction value (or the offset correction value) is calculated using the images, and stored in one memory. The offset correction value (or the gain correction value) is calculated using the image of the other memory and the calculated gain correction value (or the offset correction value).
