DYNAMIC IMAGE ENCODING DEVICE

摘要

PURPOSE: To prevent the decline of the entire picture quality evaluation for reproduced images and fluctuation in the resolution of a still part. CONSTITUTION: For AD converted image picture data, the low frequency components are passed through by a two-dimensional block unit in a variable low-pass spatial filter 12, a high efficiency encoding processing is performed in a compressor 13, they are tentatively stored in a FIFO memory 14 and a compressed data storage amount in the FIFO memory 14 is monitored by a FIFO monitoring device 15. FIFO storage information 17 which is the monitoring data and block activity information 18 for each block unit from the compressor 13 are inputted to a band controller 16 and a cut-off frequency for each block is set and instructed to the variable low-pass spatial filter 12 from the band controller 16.
