Patent ID: 8073278

Claim:
An image processing device comprising: a processing unit that restores an image before fluctuation, an image which has been intrinsically shot, an image which is approximated from the image before fluctuation and the image which has been intrinsically shot and not non-linearly corrected, referred to as an original image, and an image obtained by non-linearly correcting the original image, referred to as a non-linearly corrected original image, from a non-linearly corrected initial image which has fluctuation like deterioration and was non-linearly corrected by a predetermined process, wherein the processing unit performs the following basic processing for forming data of the original image and/or data of the non-linearly corrected original image, repeating processing using fluctuation-factor information data which become factors of fluctuating an image, initial image data which is non-linearly corrected and initial image data without being non-linearly corrected, which is not non-linearly corrected, and obtained by performing inversely non-linear correction of the non-linearly corrected initial image data; gradually generating the non-linearly corrected initial image data and comparison data which is approximated to the initial image data without being non-linearly corrected; and gradually approximating the energy of the data of the non-linearly corrected original image to zero, wherein the processing unit performs pre processing of inversely non-linear correction of the initial image data which is non-linearly corrected to obtain the initial image data without being non-linearly corrected before starting the basic processing.
