1. An image coding method, comprising:

  • performing a regulation processing on a plurality of copying parameters of a current coding block; and

    performing an entropy coding on the plurality of the copying parameters according to an order of the plurality of the copying parameters that results from the regulation processing, and generating a video bitstream comprising the plurality of the copying parameters,wherein the plurality of the copying parameters comprise one or more types of copying parameter components,wherein the one or more types of copying parameter components comprises at least one of a displacement vector horizontal component, a displacement vector vertical component, a one-dimensional displacement vector, a linear address, a relative linear address, an index, a palette linear address, a relative index, a palette relative linear address, a copying length, a copying width, a copying height, a rectangle width, a rectangle length, or an unmatched pixel,wherein performing the regulation processing on the plurality of the copying parameters of the current coding block comprises;

    dividing the plurality of the copying parameters into N subparts according to a predetermined rule, N≥

    2; and

    classifying, merging and re-sequencing same subparts of the plurality of the copying parameters; and

    then performing the entropy coding on the same subparts sequentially,wherein each of the N subparts of the plurality of the copying parameters is null or non-null.
