20090268963 | Pre-processing method and apparatus for wide dynamic range image processing - Provided are method and apparatus of pre-processing in WDR (wide dynamic range) image processing, the method of pre-processing of WDR image processing including: (a) receiving luminance and chrominance signals having different exposure times, and analyzing the correlation between a luminance signal having a first exposure time and a luminance signal having a second exposure time that is longer than the first exposure time; (b) based on the result of the analysis, dividing each of the luminance signal having the first exposure time and the luminance signal having the second exposure signal, into at least one of a bright region, a transition region, and a dark region; and (c) normalizing the regions of the luminance signal having the first exposure time to respectively correspond to the regions of the luminance signal having the second exposure times. | 10-29-2009 |
20100040300 | IMAGE PROCESSING METHOD AND APPARATUS FOR CORRECTING DISTORTION CAUSED BY AIR PARTICLES AS IN FOG - Provided are a method and apparatus for processing an image. The method includes receiving a first luminance image of an image including airlight, which is a type of light that occurs in a foggy environment, and generating an airtight map based on a ratio between an average luminance of the first luminance image, and a standard deviation; and removing the airtight by subtracting the airtight map from the first luminance image and outputting a second luminance image. According to the present invention, airlight components may be effectively removed. | 02-18-2010 |
20110096237 | APPARATUS AND METHOD FOR COLOR ROLLING SUPPRESSION - An apparatus and method for suppressing color rolling are provided. The apparatus includes a digital signal processor which detects first motion information on a current frame and second motion information on at least one of a plurality of neighboring frames, calculates a gain based on the first and second motion information, and applies the gain to at least one channel of the current frame. | 04-28-2011 |
