Abstract
The present technology relates to an image processing device and an image processing method by which various DFs can be provided. A 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, or a reduced first luminance filter having a reduced filter characteristic with respect to the first luminance filter is applied, as a second color-difference filter having a higher filter strength than a first color-difference filter, to a pixel of a color-difference component located around a block boundary in a decoded image. The present technology is applicable to image encoding and decoding, for example.
Claims14
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.
An image processing method comprising:
- applying, 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.
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 local decoded image obtained by a local decoding process during an encoding process of an 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;
- and
