Abstract
An encoding method and an encoder are provided to improve image compression performance. An embodiment of the encoding method determines an encoding quantization parameter, QP, and precodes a to-be-encoded block using the encoding QP to obtain encoding result information. The encoding QP is then adjusted based on the encoding result information, and then real encoding is performed on the to-be-encoded block by using an adjusted encoding QP. An embodiment of the encoder includes a bit rate control module to determine a first QP, and a precoding module to precode a to-be-encoded block using the QP to obtain precoding result information. The encoder further includes another bit rate control module to adjust the QP based on the precoding result information to obtain a second QP, and a real encoding module to encode the to-be-encoded block using the second QP.
