Title: Image compression encoder and method
Inventor: TANAKA YASUYUKI
IPC: H04N19/85
Filed: 2001-03-12
Abstract: PROBLEM TO BE SOLVED: To reduce deterioration in the image quality at a border of an area designated with high image quality in a moving picture. SOLUTION: A discrete wavelet converter 12 applies two-dimensional discrete wavelet conversion to an input image signal. An area designation device 14 outputs mask information denoting an area whose image quality is to be increased. An area surrounding calculation device 16 calculates a surrounding part of a border within a designated area. A low-order bit reduction device 18 replaces low-order N bits of conversion coefficient data of the surrounding part outputted from the converter 12 with zero. A quantization circuit 20 quantizes the conversion coefficient data and shifts up the data in the designated area in the obtained quantization index by a specified number of bits.  An entropy encoder 22 decomposes the quantization index received from the quantization circuit 20 into bit planes and applies binary arithmetic coding to the bit plane in the unit of bit plane to provide an output of a code stream.
