Title:
IMAGE PROCESSING APPARATUS AND IMAGE CAPTURING APPARATUS USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/121763
Kind Code:
A1
Abstract:
This invention is directed to provision of an image processing apparatus capable of obtaining high definition of images, while correcting the asymmetry of aberration. An image processing apparatus comprises: an image acquiring means for acquiring an input image; and an image recovering means for recovering the input image by use of an image recovery filter, which is generated or selected based on the transfer function of an image capturing system used for forming, as the input image, a subject image, thereby generating a recovered image. The image recovery filter causes the difference in absolute value of transfer function between two azimuthal directions used when obtaining the recovered image from the subject to be smaller than the difference in absolute value of transfer function between the two azimuthal directions of the image capturing system.
