Abstract
Disclosed in the present disclosure is a video image coding method. The method includes: dividing an image frame to be coded into a plurality of sub-blocks, and assigning coordinates to each sub-block; calculating a hash value corresponding to an i-th sub-block according to a content of the i-th sub-block; performing a search in a first hash table by using the hash value corresponding to the i-th sub-block; in response to the coordinates of the first reference block being valid, acquiring a content of the first reference block according to the coordinates of the first reference block, and comparing the content of the first reference block with the content of the i-th sub-block; and in response to the content of the first reference block being consistent with the content of the i-th sub-block, performing Intra Block Copy (IBC) coding on the i-th sub-block.
