Abstract (in Japanese) (See Japanese page) 
(in English) This paper deals with a refocusing problem using multiple images captured with a circular camera array.
A novel inverse filtering method for generating arbitrarily focused images at the center of the camera array is presented
and discussed in a framework of image restoration problem.
The derived inverse filter does not depend on the scene structure; hence the presented method requires no scene estimation.
Effect of the camera number on quality of the generated image is tested in the simulation using synthetic images.
