摘要 |
An image coding method includes: generating a predicted block (S6001); calculating a residual block (S6002); calculating quantized coefficients by performing transform and quantization on the residual block (S6003); calculating a coded residual block by performing inverse quantization and inverse transform on the quantized coefficients (S6004); generating a temporary coded block (S6005); determining whether or not an offset process is required, to generate first flag information indicating a result of the determination (S6006); executing the offset process on the temporary coded block when it is determined that the offset process is required (S6012); and performing variable-length coding on the quantized coefficients and the first flag information (S6011). |
