Abstract
Provided is an image processing device including a decoding section that decodes an encoded stream to generate an image, a line determining section that determines whether to apply a deblocking filter to each of lines perpendicular to a boundary in neighboring blocks neighboring across the boundary in the image generated by the decoding section, and a filtering section that applies the deblocking filter to each line to which the line determining section determines to apply the deblocking filter.
Claims5
An image processing device, comprising:
- a central processing unit (CPU) configured to:
- determine whether to apply a deblocking filter to a first set of pixels of a specific line of eight lines in a respective 8×8 neighboring block of a plurality of 8×8 neighboring blocks within a decoded image, wherein
- the eight lines include 0th to 7th lines, orthogonal to a boundary, within the respective 8×8 neighboring block of the plurality of 8×8 neighboring blocks,
- a first 8×8 neighboring block of the plurality of 8×8 neighboring blocks neighbors a second 8×8 neighboring block of the plurality of 8×8 neighboring blocks across the boundary within the decoded image,
- the specific line is other than 0th, 3rd, 4th, and 7th lines of the eight lines, and
- the determination is based on a second set of pixels of the 0th, 3rd, 4th, and 7th lines of the eight lines of the respective 8×8 neighboring block;
- and
- apply, based on the determination, the deblocking filter to the first set of pixels of the specific line.
