  • Patent number: 9769496
    Abstract: Provided is an image encoding device including an encoding unit that encodes a down-sampling image obtained by performing down-sampling of a color difference signal; a decoding unit that decodes the encoded encoding image; and a filter information generation unit that performs up-sampling of a color difference signal of the decoded decoding image, filters the color difference signal of the decoded image by using the up-sampled color difference signal of the decoded image and a luminance signal as reference signals, and acquires filter information related to the filtering.
