IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD
First Claim
1. An image processing apparatus comprising:
- a positional displacement estimation unit configured to estimate positional displacement between a plurality of input images obtained by photographing an identical photographic subject;
an alignment processing unit configured to align positions of the plurality of input images on a basis of the estimated positional displacement; and
a lens information estimation unit configured to estimate lens information of a lens used to photograph the input image depending on a deterioration model indicating a deterioration component of the lens on a basis of the aligned input images.
