An image signal processor for image enhancement is provided. The image signal processor receives a first, a second, and a third component of an RGB signal of each pixel of an image, and has: an image enhancer for performing image enhancement on the first component of the RGB signal to produce a first enhanced component of the RGB signal; a gain generator, coupled to the image enhancer, for producing an enhancement gain based on the first component and the first enhanced component of the RGB signal; and a gain multiplier, coupled to the gain generator, for performing image enhancement on the second and the third component based on the enhancement gain to produce a second and a third enhanced component. |
