The embodiment of the invention provides an image intra-frame prediction method and an apparatus. The method comprises the steps of dividing a current coding depth unit into a first partition and a second partition; depending on distribution of pixel points in the first partition and the second partition, determining a first pixel point in a reference pixel as a CPV predicted value of the first partition, and determining a second pixel point in the reference pixel as a CPV predicted value of the second partition; carrying out intra-frame prediction on the current coding depth unit depending on the CPV predicted value of the first partition and the CPV predicted value of the second partition. According to the embodiment of the invention, CPV predicted values of two partitions are directly determined, thus reducing complexity of selecting CPV and avoiding influence on a coding result.
