A method comprises obtaining a bit depth of a current picture; obtaining a quantization parameter (QP) of a current coding unit (CU), where the current CU belongs to the current picture; obtaining a picture complexity level of the current CU; obtaining a prediction residual value of a current point, where the current point is located in a first row of the current CU, a prediction value of the current point is a reconstruction value of a reference point, and the reference point is located on an upper side of the current point; and obtaining a QP of the current point based on the bit depth of the current picture, the QP of the current CU, the picture complexity level of the current CU, and the prediction residual value of the current point.
