METHOD AND APPARATUS FOR COLOR FILTER ARRAY JUDGEMENT OF DIGITAL CAMERA BASED ON INTERMEDIATE VALUE COUNTING

摘要

The present invention relates to a digital image judging technology and, more specifically, relates to a method to judge a color filter array which estimates the color filter array from one digital image and a device thereof. The method comprises: a step of obtaining single image information; a step of estimating a shape of the color filter array by using the single image information; a step of counting a number of pixels in accordance with an intermediate value condition; a step of determining first a location of a green channel; a step of determining locations of the remaining red and blue channels; a step of estimating the color filter array by a block unit; and a step of determining whether an image is forged by the estimated color filter array.
