Image Processing Device Image Processing Method And Program

Abstract: A device and a method for performing false color correction occurring in areas of localized highlight in an image are provided. During a data conversion process to generate an RGB array image from an RGBW array image false color pixels are detected; low band signals which correspond to each of the RGBW colors and which differ depending on whether a pixel is a false color pixel or not are calculated; and the RGBW array image is converted by an interpolation process in which the calculated low band signals are applied to generate the RGB array image. In the interpolation process the low band signals are utilized on the basis of the assumption that the W low band signal mW and the RGB low band signals mR mG mB have a proportional relationship within a local area. In cases in which a pixel of interest is a false color pixel the low band signal is calculated by applying a low pass filter having a coefficient in which the contribution of pixel values closer to the pixel of interest is relatively less than that of more distant pixels.
