1. US20160210760 - Image processing device, method of processing image, and image processing program including false color correction

There are provided a device and method that correct a false color occurring in a locally highlighted region in an image. A false color pixel is detected in data conversion processing of generating an RGB array image from an RGBW array image, low-band signals corresponding to respective RGBW colors that are different according to whether a pixel is a false color pixel, and the RGBW array is converted by interpolation processing to which the calculated low-band signals are applied to generate the RGB array image. The interpolation processing is performed using the low-band signals on an assumption that a W low-band signal mW, and RGB respective low-band signals mR, mG, and mB have a proportional relation in a local region. When a pixel of interest is a false color pixel, the low-band signal is calculated by an application of a low-pass filter having a coefficient in which a contribute rate of pixel values in the vicinity of the pixel of interest is made relatively lower than that of separated pixels.
