Image processing circuit of the image processing apparatus having image processing filters, the image processing method and an image processing filter for image processing filter
An image processing filter for correcting a pixel value of an image includes a flatness calculation unit 40 for calculating a flatness of distribution of pixel values of surrounding pixels positioned on the periphery of a target pixel to be filtered, and a pixel value composition unit 50 for blending the pixel value of the target pixel and the pixel value of the surrounding pixels, on the basis of a blend ratio corresponding to the flatness calculated by the flatness calculation unit 40, and generating a composite pixel value by combining the pixel value of the target pixel and the pixel value of the surrounding pixels.
