An image processing apparatus includes a brightness fluctuation extraction section, a color difference fluctuation extraction section, a conversion section, and an addition section. The brightness extraction section extracts a local fluctuation component from brightness information (hereinafter, a brightness fluctuation) in the image data. The color difference fluctuation extraction section extracts a local fluctuation component from color difference information (hereinafter, a color difference fluctuation) in the image data. The conversion section weightedly adds the color difference fluctuation and the brightness fluctuation to generate a pseudo texture component. The addition section adds the generated texture component to the brightness information. In the above-described structure, the conversion section adjusts and changes a weighting ratio of the weighted addition so as to make ratios of noises of color components included in the texture component substantially equal.
