摘要： Said method comprises using a processing means for quantizing a transform of a residual of an intra-prediction of the image block using a quantization parameter value and encoding the quantized transform, further using a processing means for determining that an already used quantization parameter value and corresponding coding cost are available in a storage means, the already used a quantization parameter value being already used for quantizing of a further image block close resembling the image block or having a same complexity as the image block and using the already used quantization parameter value, the corresponding coding cost and a target bit rate for determining the quantization parameter value. Thus, the quantization parameter value can be determined such that flickering artifacts are avoided.
