US Patent 9123130 Image processing device and method with hierarchical data structure

The present technology includes a setting unit that sets the position of a boundary of image data in an upper hierarchy unit to be in a lower hierarchy unit that is lower than the upper hierarchy unit when the image data is encoded in a unit of encoding with a hierarchical structure; an encoding unit that generates encoded data by encoding the image data according to the position of the boundary set by the setting unit; and an addition unit that adds information on the image data in the upper hierarchy unit before encoded data in an intermediate hierarchy unit that includes the boundary set by the setting unit, is lower than the upper hierarchy unit, and is higher than the lower hierarchy unit. The present technology can be applied to, for example, an image processing device.
