IMAGE-PROCESSING DEVICE, AND IMAGE-PROCESSING METHOD

摘要

[Problem] To lighten performance requirements for an encoder as compared with a method in which all block sizes are searched for comprehensively. [Solution] The present invention provides an image-processing device equipped with: a setting part for setting the size of a coding unit that is formed by recursively dividing an image to be coded and/or a prediction unit that is set in units of the coding unit in accordance with the range of a search for the size of the coding unit and/or the prediction unit in which range one or more candidate sizes beginning with the smallest among all candidate sizes are excluded; and a coding part for coding the image in accordance with the size of the coding unit and the prediction unit that are set by the setting part.
