1. A color transform method performed by an electronic device, the color transform method comprising:
generating an initial color transformed image by performing color transform on a raw image;
determining noise amplification degrees corresponding to a noise amplification degree for a first color value in a color space of the raw image based on a first transformed color value obtained by color transform on the first color value, and second transformed color values obtained by color transform on neighboring color values of the first color value, or determining a noise amplification degree for a color value of a first pixel in the raw image based on the color value of the first pixel, color values of neighboring pixels of the first pixel, a third transformed color value obtained by color transform on the color value of the first pixel, and fourth transformed color values obtained by color transform on the color values of the neighboring pixels;
processing the determined noise amplification degrees; and
generating a final color transformed image by filtering the initial color transformed image using the processed noise amplification degrees and at least one of the raw image or luminance information of the raw image.
