Quantization control method and the quantization control system adapted to real-time

摘要

PROBLEM TO BE SOLVED: To provide a real-time solution of an adaptive quantization control in order to enhance the subjective quality of a picture.;SOLUTION: A system and method for controlling video compression quantization comprises: generating a quantizer scale offset based on diagonal frequencies of luminance components of data block samples, luminance intensity of the samples and motion activity of the data block; adjusting a first quantizer scale using the quantizer scale offset to receive a second quantizer scale; and quantizing the data block using the second quantizer scale.;COPYRIGHT: (C)2009,JPO&INPIT
