Method and apparatus for compressing picture-representing data

摘要

First data representing a picture is quantized into quantization-resultant data. Information corresponding to a predetermined special effect on a picture represented by the quantization-resultant data is generated in response to the quantization-resultant data. The quantization-resultant data is converted into conversion-resultant data. The conversion-resultant data and the information are multiplexed into multiplexing-resultant data. The multiplexing-resultant data is compressed into compression-resultant data of a predetermined code.
