Abstract: A method for inter prediction of a sample value of a current pixel of a plurality of pixels of a current block of a current frame of a video signal is proposed. The method (800) comprises: determining (801) a plurality of block-wise motion vectors related one-to-one to a plurality of blocks of the current frame; determining (803) a pixel-wise motion vector of the current pixel based on the plurality of block-wise motion vectors; determining one or more reference pixels in the reference frame based on the pixel-wise motion vector of the current pixel; and determining (805) an inter predicted sample value of the current pixel based on one or more sample values of the one or more reference pixels in the reference frame. Coding efficiency is thus improved.

Abstract: The disclosure relates to an image processing apparatus. The image processing apparatus comprises processing circuitry configured to: obtain a direction angle value associated with the target pixel (12a-c); select for the target pixel (12a-c) a plurality of primary interpolation support pixels (10a-d) from the array of pixels (10a-d) on the basis of the position of the target pixel (12a-c); determine pixel values of a first and a second secondary interpolation support pixels (11ac, 11bd) on the basis of the pixel values of the selected primary interpolation support pixels (10a-d), the direction angle value (a, b) and the position of the target pixel (12a-c); and determine the interpolated pixel value of the target pixel (12a-c) on the basis of the pixel values of the first and second secondary interpolation support pixel (11ac, 11bd) and the position of the target pixel (12a-c).
