Abstract: Specifying defective pixels can be done with higher precision. With the imaging apparatus 1, defective pixels are specified after NUC process with respect to initial good pixels, as well as correction with respect to initial defective pixels, has been done, and therefore it is possible to specify defective pixels with higher precision as compared with the case where defective pixels are specified without carrying out the NUC process and correction with respect to initial defective pixels. In addition, captured-image data acquired by defective pixels other than the initial defective pixels can be corrected in the controlling means 40, because pixels in which defect other than the initial defect is caused can be specified by specifying defective pixels after corrected captured-image data has been generated in a manner such that captured-image data which is acquired by the image capturing unit 10 is corrected on the basis of information for specifying an initial defective pixel.
