The high frequency image data is separated into windows, with each window containing pixels. The low frequency image data is separated into windows corresponding respectively to the plurality of windows of the high frequency image data, with each window containing pixels. For each window in the high frequency image data, a number of textured pixels in the window is determined, the textured pixels being pixels that vary greatly in luminance value with respect to other pixels in the window, and a window modification is determined such that the number of textured pixels in the window is reduced. For each corresponding window in the low frequency image data, the window modification is applied, and each textured pixel in the window is corrected based upon the other pixels in the window.

Abstract: An electronic device includes an image sensor configured to acquire raw image data in a color filtered array format. A processor is coupled to the image sensor and configured to demosaic the raw image data in the color filtered array format into RGB image data having red data, green data, and blue data. The processor also performs color noise reduction on the red data, green data, and blue data of the RGB image data so as to produce corrected image data. The processor further converts the corrected image data into corrected image data in the color filtered array format.
