ABSTRACT:
A CPU (11) checks a photographic storing mode for a still image or animate object which is determined when photography takes place and a compression rate mode (a compression rate depends on normal, economy, and the like). When the checked mode coincides with a photographic storing mode or compression rate mode stored in an EEPROM (12) when photographs were taken, a scale factor is read which is stored in the EEPROM (12) in correspondence with the respective modes and which has been used for compressing and coding. After that, the scale factor is set in a data compression/extension section (7) and is used as a scale factor for the compression/coding in the present photography. Accordingly, the time required to determine a scale factor is shortened, and an error generated when an image signal is stored is prevented. Accordingly, a good photographic result can be obtained.
