Abstract
A digital image recording and/or reproducing apparatus using a plurality of compression methods may include, in a recording section, (a) data compression circuitry, including a plurality of compression circuits which have different compression methods, for changing a compression rate for input digital image data by changing a combination of the plurality of compression circuits compressing the digital input image data and (b) circuitry for recording (1) the digital image data compressed by the data compressing circuit and (2) data representing the compression rate of the digital image data compressed by the data compressing circuit. The apparatus may include a reproducing section having (a) a reproducing circuit for reproducing from the recording medium the digital image data compressed with the compression rate provided by the combination of different compression methods, (b) detecting circuitry for detecting the data representing the predetermined compression rate stored on the recording medium, and (c) reconstruction circuitry for reconstructing the digital image data reproduced by the reproducing circuitry according to the representing data detected by the detecting circuitry.
