Abstract
An image processor includes an encoder and a decoder. The encoder includes a frequency transform unit, a pre-filter, and a color conversion unit that converts a pixel signal of a first color space inputted from outside into a pixel signal of a second color space including a luminance signal and chrominance signals. The decoder includes a frequency inverse transform unit, a post-filter, and a color inverse conversion unit that inversely converts a pixel signal of the second color space into a pixel signal of the first color space. The pre-filter performs prefiltering on one or plural specific signals among the luminance and chrominance signals. The post-filter does not perform postfiltering on the above specific signals.
