Abstract
An image processing method includes the steps of obtaining information on an optical transfer function used for image capturing, generating correction information used to correct the optical transfer function based on a first image generated by the image capturing and a second image that is focused on a defocus area in the first image, and performing a filter process for the first image using the correction information and information on the optical transfer function.
