1. An encoding apparatus comprising:
a filtering process unit configured to perform, based on an intra smoothing enabled flag, a filtering process on a reference pixel referred to when performing intra prediction on a pixel of a current block by using a bi-linear interpolation filter in a case where a value calculated by using the reference pixel is lower than a threshold value set according to a bit depth of image data; and
an intra prediction unit configured to perform intra prediction on a current pixel contained in the current block using the reference pixel for which the filtering process is performed by the filtering process unit, and generate a prediction image in encoding process,
wherein the filtering process unit and the intra prediction unit are each implemented via at least one processor.
