Abstract
The inter prediction method is provided, which includes: obtaining a predicted sample value of a current affine block; determining one or more luminance compensation blocks based on motion vectors of one or more subblocks of the current affine block; determining a linear model coefficient based on a first sample set and a second sample set, where the first sample set includes at least one reconstructed sample neighboring to an edge of the current affine block, the second sample set includes at least one reconstructed sample neighboring to an edge of the one or more luminance compensation blocks, and the sample in the first sample set is in a one-to-one correspondence with the sample in the second sample set; and updating the predicted sample value of the current affine block based on the linear model coefficient, to obtain an updated predicted sample value of the current affine block.
