PROBLEM TO BE SOLVED: To provide an imaging device in which the noise included in a captured image is corrected appropriately, and to provide a noise correction method.SOLUTION: Noise included in a captured image is corrected by using a plurality of noise images. A system control circuit 300 controls an imaging CMOS22 to capture a subject image by using arbitrary shooting conditions, thus obtaining a captured image. Subsequently, the shooting conditions and acquisition conditions are compared thus calculating adjustment coefficients. Thereafter, adjustment coefficients k1 and k2 are calculated by using the shooting conditions of the captured image and the acquisition conditions of noise images 1 and 2. Furthermore, noises a and b are corrected, by using the adjustment coefficients k3 obtained by subtracting the adjustment coefficient k1 from k2. D4=D3-k1 D1-k3 D2, where D1 is the pixel data of the noise image 1, D2 is the pixel data of the noise image 2, D3 is the pixel data of the captured image, and D4 is the pixel data of an image subjected to noise correction. |
