An image enhancement method and system are provided. The image enhancement method and system are capable of improving image quality by performing gamma corrections on global and local illuminations and reflectance estimated from an input image, in consideration of dynamic range and contrast of the image, respectively. Particularly, in a case of a color image, the red, green, and blue (RGB) component images are converted into hue, saturation, and value (HSV) component images, and the global and local illuminations and reflectance estimated from the V component image. By converting the hue (H), saturation (S), and enhanced value (V) into RGB, an enhanced color image can be obtained.
