Abstract: The present disclosure relates to an image processing device and an image processing method that enable image processing to be performed with a smaller number of line buffers. The image processing device includes a decoding unit that decodes a bitstream to generate an image according to an encoding standard in which a horizontal size of one tile is restricted for each level by a restriction value. The restriction value is set according to a maximum value MaxLumaPs of the number of luminance picture samples, and also restricts a vertical size of one tile. The present technology can be applied to, for example, an image processing system that performs encoding and decoding according to the VVC method.

Abstract: A decision unit decides whether or not a deblocking filter is applied to color difference components of pixels belonging to a line orthogonal to a block boundary in two adjacent blocks adjacent to each other sandwiching the block boundary of the decoded image, by using color difference components of pixels belonging to a line identical to a line used to decide whether or not the deblocking filter is applied to luminance components of the pixels belonging to the line orthogonal to the block boundary. The filtering unit applies the deblocking to the color difference components of the pixels for which it is decided that the deblocking filter is applied. The present technology can be applied to, for example, a case where encoding and decoding of an image are performed.

A filter strength setting unit (105) sets the strength of the deblocking filter to operate on the block boundary (Bv) on the basis of the depth value (Da, Db).
