| 发明名称 | Recording medium having recorded thereon coded information using plus and/or minus rounding of images | ||
| 摘要 | A method of decoding images including: extracting motion vector information from input information to be decoded; synthesizing a prediction image by performing motion compensation using the motion vector information and a reference image which is a previously decoded image; and synthesizing a decoded image by adding the prediction image to an error image, wherein the motion compensation includes specifying either a positive rounding method or a negative rounding method for interpolating intensity values of pixels in performing the motion compensation. | ||

| 主权项 | 1. A non-transitory computer-readable medium having stored thereon an image decoding program which, when executed by a computer, effects operations comprising: extracting motion vector information, and rounding method information from input information to be decoded; synthesizing a prediction image by performing motion compensation using the motion vector information and a reference image which is a previously decoded image; and synthesizing a decoded image by adding the prediction image to an error image, wherein the motion compensation includes specifying either a positive rounding method or a negative rounding method for interpolating intensity values of pixels in performing the motion compensation. | ||
