Claim 0:
1. A picture reconstruction method, comprising:
obtaining a prediction mode of a current coding unit;
obtaining a prediction partition mode of the current coding unit, wherein the current coding unit comprises a luma coding block and a chroma coding block, and the prediction partition mode is a mode of splitting the current coding unit into prediction blocks or prediction units;
obtaining a transform block of the current coding unit based on the prediction partition mode and the prediction mode; and
generating a reconstructed picture block of the current coding unit based on the transform block, wherein obtaining the transform block of the current coding unit based on the prediction partition mode and the prediction mode further comprises:
when the prediction mode is the intra prediction mode and the prediction partition mode of the luma coding block is either a vertical quartering partition or a vertical asymmetric binary split, splitting the luma coding block through the vertical quartering partition to obtain a luma transform block, and skipping splitting the chroma coding block and using the chroma coding block as a chroma transform block; or
when the prediction mode is the intra prediction mode and the prediction partition mode of the luma coding block is either a horizontal quartering partition or a horizontal asymmetric binary split, splitting the luma coding block through the horizontal quartering partition to obtain a luma transform block, and skipping splitting the chroma coding block and using the chroma coding block as a chroma transform block, and wherein obtaining the transform block of the current coding unit based on the prediction partition mode and the prediction mode further comprises:
when the prediction mode is the inter prediction mode, skipping splitting the current coding unit and using the current coding unit as a transform unit.
