The embodiments of the disclosure provide an interpolation filtering method and apparatus for intra-frame prediction, a medium, and an electronic device. According to a distance between a prediction pixel and a first reference pixel, a target filter matching the distance is selected from a filter parameter corresponding to a specified prediction unit, and interpolation filtering processing is performed on a second reference pixel by using the target filter, to obtain a predicted value of the prediction pixel.
