Abstract:
1. An image processing method performed by an image processing device, the method comprising: performing a data conversion process of receiving an input of an RGBW (Red Green Blue White) array image and generating an RGB (Red Green Blue) array image as an output image, wherein the data conversion process includes: calculating interpolated pixel values r1, g1, and b1 corresponding to an array of the RGB array image by performing a pixel interpolation process on the RGBW array image; detecting whether each pixel is a purple fringe pixel by analyzing the RGBW array image; calculating corrected pixel values r2, g2, and b2 by correcting pixel values of the purple fringe pixels; and calculating constituent pixel values RGB of the output image by performing a blend process of blending the interpolated pixel values r1, g1, and b1 calculated in the process of calculating interpolated pixel values with the corrected pixel values r2, g2, and b2 calculated in the process of calculating the corrected values.
