1. An image processing apparatus that performs image processing on an image supplied from an imaging apparatus that captured an original image and that performed gamma processing on the original image to generate the image to be supplied to the image processing apparatus, the image processing apparatus comprising: inverse gamma processing means for performing inverse gamma processing on the image supplied from the imaging apparatus so that the image has characteristics the same as characteristics of the original image, which corresponds to the image before the image was subjected to the gamma processing in the imaging apparatus; and correction processing means for performing correction processing on the image subjected to the inverse gamma processing using the inverse gamma processing means so that blur in the image is corrected.
