Abstract
An encoding device may include a quantization controller configured to generate, for each of basic blocks constituting image data, quantization parameters for each of a plurality of sample blocks for partitioning the basic blocks, and a quantizer configured to quantize the image data based on at least one of the quantization parameters, wherein the quantization controller is further configured to generate initial quantization offsets corresponding to preliminary blocks generated by partitioning the image data according to each of the plurality of sample blocks, generate final quantization offsets corresponding to the preliminary blocks by adjusting the initial quantization offsets to be included in offset ranges corresponding to the preliminary blocks, respectively, wherein the offset ranges are set based on sizes of the preliminary blocks, respectively, and generate the quantization parameters based on the final quantization offsets.
