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.
