Abstract
Official abstract text for this publication.
An image processing method of performing an image restoration processing of an image, includes the steps of generating a plurality of first optical transfer functions depending on a position of the image using coefficient data depending on an image pickup condition of the image, generating a plurality of second optical transfer functions by rotating the first optical transfer functions around a center of the image or around an optical axis of an image pickup optical system, generating an image restoration filter based on the first optical transfer functions and the second optical transfer functions, and performing the image restoration processing of the image using the image restoration filter.
First claim
Opening claim text (preview).
What is claimed is: 1. An image processing method of performing an image restoration processing of an image, the image processing method comprising the steps of: reconstructing optical transfer functions of an image pickup optical system depending on a position of the image using coefficient data depending on an image pickup condition of the image; expanding the optical transfer functions by rotating the optical transfer functions around a center of the image or around an optica…
