Abstract
The present invention provides an encoding method, which includes steps of: determining a first quantization parameter of a first superblock of an image frame; determining a binary code for the first superblock; determining whether binary code information of the first superblock is greater than a first threshold; and if the binary code information of the first superblock is greater than the first threshold, increasing a second quantization parameter of a second superblock.
Claims16
An encoding method of an encoder, comprising:
- determining a first quantization parameter of a first superblock of an image frame;
- determining a binary code for the first superblock, wherein the binary code is subsequently encoded or compressed to generate encoded data of the first superblock;
- determining whether binary code information of the first superblock is greater than a first threshold;
- and
- if the binary code information of the first superblock is greater than the first threshold, increasing a second quantization parameter of a second superblock;
- wherein the binary code information of the first superblock is binary code data amount or a binary rate of all superblocks that have already determined their binary codes in a row of superblocks to which the first superblock belongs.

An encoder, configured to perform steps of:
- determining a first quantization parameter of a first superblock of an image frame;
- determining a binary code for the first superblock, wherein the binary code is subsequently encoded or compressed to generate encoded data of the first superblock;
- determining whether binary code information of the first superblock is greater than a first threshold;
- and
- if the binary code information of the first superblock is greater than the first threshold, increasing a second quantization parameter of a second superblock;
- wherein the binary code information of the first superblock is binary code data amount or a binary rate of all superblocks that have already determined their binary codes in a row of superblocks to which the first superblock belongs.
