Methods, systems and devices including an encoder for image processing
A method of operating an encoder is provided. The method includes generating predicted spatial-domain block values for current spatial-domain block pixel values, generating residual spatial-domain block values based on differences between the current spatial-domain block pixel values and the predicted spatial-domain block values, calculating a representative value of the residual spatial-domain block values, selecting a quantization parameter corresponding to the representative value from among a plurality of quantization parameters, and quantizing the residual spatial-domain block values using the selected quantization parameter.
