1. An image processing device comprising:
filtering circuitry that applies, as a second chrominance filter having a higher filter strength than a first chrominance filter, a reduced second luminance filter or a reduced first luminance filter to a pixel of a chrominance component located around a block boundary in a decoded image, the reduced second luminance filter having a reduced filter characteristic with respect to a second luminance filter having a higher filter strength than a first luminance filter, the reduced first luminance filter having a reduced filter characteristic with respect to the first luminance filter.
