PROBLEM TO BE SOLVED: To obtain a normal image by correcting a shaken or out-of-focus image. SOLUTION: After acquisition of an image of longitudinal m-pixel×lateral n-pixel (step 101), a matrix C whose elements are luminance information of pixels of an input image and a matrix B whose elements are luminance information of pixels of a correction image are defined. The elements of each row correspond to each pixel of the input image and elements of each column correspond to each pixel of the correction image. A conversion matrix A denoting C=A×B is generated (step 102). Elements of one row of the matrix A corresponding to a specific pixel of the input image indicate a ratio of number of pixels of the corrected image being specific pixels. An inverse matrix A<-1> of the matrix A is obtained (step 103) and the input image is converted into the correction image by obtain the matrix B of the correction image (step 104). |
