WIPO Patent Application WO/2017/183273
Kind Code:
A1
Abstract:
A technique is disclosed for reducing false color or color moire occurring in a RAW image due to a demozaicing process. In an image processing device 10, a RAW image input unit 11 acquires a RAW image from a camera 20, and a demozaicing processor 12 performs a demozaicing process on the acquired RAW image. A false color remover 14 calculates difference values from a G pixel for an R pixel and a B pixel in RGB color information of the image data after the demozaicing process, repeats a median filter of an m × n pixel multiple times on the difference pixel data after the calculation, and reduces color moire occurring due to the demozaicing process.
