Abstract
In an apparatus, it is determined whether a covariance matrix calculated based on a plurality of patches is abnormal. In a case where it is determined that the covariance matrix is not abnormal, the covariance matrix is used to perform first correction on pixels included in the plurality of patches. In a case where it is determined that the covariance matrix is abnormal, second correction, which is different from the first correction, is performed on the pixels included in the plurality of patches.
