Abstract: Encoding apparatuses are provided. The encoding apparatus includes: a first buffer configured to buffer a quantized coefficient of an image block that is input by a quantization circuit; an information generation circuit configured to detect the quantized coefficient of the image block sequentially to obtain run-length encoding information; a second buffer configured to buffer the run-length encoding information generated by the information generation circuit; and a processing circuit configured to: when the second buffer stores run-length encoding information, read the run-length encoding information from the second buffer, read the quantized coefficient corresponding to the run-length encoding information from the first buffer, and output the run-length encoding information and the corresponding quantized coefficient to an entropy encoding circuit.
