| 摘要 |
The present technology relates to an image processing device and a method capable of improving encoding efficiency. In a weighted prediction process performed in an image encoding process or in an image decoding process, a motion compensation unit that performs motion compensation of sub-pixel accuracy for each of L0 and L1, a weighted addition unit that applies weighted addition to arithmetic operation results by the motion compensation unit, and a rounding processing unit that suppresses a decrease in arithmetic operation accuracy by performing a necessary rounding process once with respect to an arithmetic operation result by the weighted addition unit are provided. The present disclosure can be applied to an image processing device. |
