Method for compressing picture-representing data and data recovery program |
摘要 |
<p>A method of compressing first data representing a picture, comprises the steps of quantizing the first data into quantization-resultant data; generating information in response to the quantization-resultant data, the information corresponding to a predetermined special effect on a picture represented by the quantization-resultant data, the information being changeable between first and second different states; converting the quantization-resultant data into conversion resultant-data being changeable among a predetermined number of different states; run-length encoding the conversion resultant-data into encoding-resultant data; multiplexing the conversion-resultant data and the information into multiplexing-resultant data of a first predetermined code having a set of different first code words, wherein second code words selected from among the first code words are assigned to the conversion-resultant data and also the first state of the information, while a third code word selected from among the first code words and differing from the second code words is assigned to the second state of the information; and compressing the multiplexing-resultant data into compression-resultant data of a second predetermined code. <IMAGE></p> |
