QUANTIZATION COEFFICIENT CONTROL METHOD, APPARATUS THEREOF, AND COMPUTER READABLE MEDIUM CAPABLE OF CONTROLLING QUANTIZATION COEFFICIENT BASED ON A PIXEL VALUE OF AN IMAGE AREA

摘要

PURPOSE: A quantization coefficient control method, apparatus thereof, and computer readable medium are provided to transmit and receive an image which is less than 1Mbps bit rate.;CONSTITUTION: An apparatus calculates I(m,n,k) through raw data of K number frame(500). If I(m,n,k) is more than T1, the apparatus sets up 1 at DFG(m,n,k). The apparatus sets up 0 at DFG(m,n,k)(510, 515). The apparatus performs the object masking(540). The apparatus sets up 0 or 1 at DV(m,n)(570,580).;COPYRIGHT KIPO 2011
