<p>Disclosed are an image processing device and method that are able to increase coding efficiency as well as to suppress an increase in the amount of processing when generating predicted motion vector information. Using supplied motion vector information of the vicinity, a motion vector information coding unit (76) generates predicted motion vector information of a target block, and generates motion vector difference information that is of the target block and that is the difference between the predicted motion vector information and the motion vector information of the target block. Furthermore, the motion vector information coding unit (76) generates secondary motion vector difference information that is of the target block and that is the difference between the motion vector difference information of the target block and motion vector difference information of a corresponding block from a motion estimation/compensation unit (75). The generated motion vector difference information and secondary motion vector difference information of the target block are supplied to the motion estimation/compensation unit (75). The present disclosures can, for example, be applied in an image coding device that codes using the H.264/AVC method as a base.</p> |
