Claim:
1. An image processing apparatus which performs, using a prediction parameter used in predictive image generation for a prediction unit included in a picture, predictive image generation for a prediction unit included in another picture, the image processing apparatus comprising: a first storing unit for storing a plurality of prediction parameters used in predictive image generation for a plurality of prediction units corresponding in size to at least one picture; a second storing unit for storing two or more prediction parameters used in predictive image generation for two or more prediction units among the plurality of prediction units; and a transferring unit configured to collectively transfer, for predictive image generation, (i) two or more of the prediction parameters from the first storing unit to the second storing unit or collectively transfer (ii) the two or more prediction parameters used in the predictive image generation for the two or more prediction units from the second storing unit to the first storing unit, wherein the transferring unit is configured to collectively transfer (i) the two or more of the prediction parameters for predictive image generation from the first storing unit to the second storing unit, the two or more of the prediction parameters including: (i) a prediction parameter used in predictive image generation for a second prediction unit included in a second picture different from a first picture including a first prediction unit, the second prediction unit being located at a lower right position with respect to the first prediction unit for which predictive image generation is performed; and (ii) a prediction parameter used in predictive image generation for a third prediction unit included in the second picture, the third prediction unit corresponding in position to the first prediction unit.
