IMAGE CORRECTING DEVICE, AN IMAGE PROCESSING DEVICE AND METHODS CAPABLE OF PERFORMING GAUSSIAN FILTERING

摘要

PURPOSE: An image correcting device, an image processing device and methods are provided to properly correct a faded image, thereby making with complete fidelity by using the faded image.;CONSTITUTION: A Gaussian filter unit(120) performs Gaussian filtering of a photo image. After a classification map generating unit(140) changes the Gaussian filtering photo image into L-Cyb-Crg color space, the classification map generating unit generates a chromaticity classification map based on a Cyb-Crg color coordinate value. A calculating unit(150) calculates average chromaticity for each area by using the chromaticity classification map. A changing unit(130) changes the Gaussian filtering photo image into C-M-Y color space. A correcting unit(160) corrects chromaticity for each area of the photo image by using a value calculated in the changing unit and the calculating unit.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Inputting unit; (120) Gaussian filter unit; (130) Changing unit; (140) Classification map generating unit; (150) Calculating unit; (160) Correcting unit
