Abstract

PURPOSE:To select various compressing systems by changing a program for data compression in a camera according to an electric signal to be supplied out of the camera. CONSTITUTION:A program ROM for determining the compressing system is built in a data compression part 5 and for the ROM, a reloadable EEPROM (electrically erasable programmable read only memory) is used. A memory cartridge is prepared for image pickup and for compression program and when the latter one is used, the contents of the EEPROM in the data compression part 5 are reloaded to the contents of the program compression cartridge by a system controller 8. Thus, the electric signal is supplied out of the camera and the program for compression can be changed.
