Abstract
A texture reproduction system and method and a chroma correction system and method for presence enhancement are provided. The texture reproduction system including: a texture analysis unit to classify a pixel included in an input image using Red Green Blue (RGB) values of the pixel; a chroma correction unit to correct a chroma based on at least one of an average chroma value of the input image and a hue value of the pixel according to a classification of the pixel; and a spatial filter unit to output a final output value of the pixel via a high frequency component extracted using the RGB values for each pixel.
