To provide a video coding method with which prediction efficiency and coding efficiency can be optimized and a video coding device. A video coding device (100) codes video data by performing a motion compensation with decimal pixel accuracy by using an adaptive interpolation filter for calculating a pixel value of a decimal pixel that performs interpolation between integer pixels configuring an input image included in the video data. The video coding device (100) comprises a motion compensation prediction unit (160) which sets a filter characteristic of the adaptive interpolation filter for each predetermined process unit, decides a plurality of filter coefficients of the adaptive interpolation filter having the set filter characteristic for each location of the decimal pixels that are relative to the integer pixel, and performs the motion compensation with the decimal pixel accuracy by applying the adaptive interpolation filter having the plurality of decided filter coefficients to the input image, a subtractor (110) which generates a prediction error by performing a subtraction between the prediction image generated by the motion compensation and the input image and an entropy coding unit (190) which codes the prediction error. |
