Title:
IMAGE PROCESSING SYSTEM AND COMPUTER-READABLE RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2015/190136
Kind Code:
A1
Abstract:
A technique for more appropriately removing fog from within an image has been sought after. The present invention provides an image processing system that is provided with: a luminance evaluation value derivation unit that derives an evaluation value for luminance in at least a portion of an image; a saturation evaluation value derivation unit that derives an evaluation value for saturation in at least a portion of the regions of the image; a contrast evaluation value derivation unit that derives an evaluation value for contrast in at least a portion of the regions of the image; and a haze concentration estimation unit that derives an estimate value for the haze concentration of the image on the basis of the contrast evaluation value, the luminance evaluation value, and the saturation evaluation value.
