Abstract
Abstract A digital electronic still camera has a detachably loaded memory cartridge. The cartridge includes control data representative of its status. The camera has an imaging unit for shooting an object field to produce an image signal. The image signal is connected into digital image data. A connector detachably connects the memory cartridge to a converter. A manual operation unit responsive to manual operation can generate a first instruction signal for preparation for shooting by the imaging unit and a second instruction signal to instruct shooting to be achieved by the imaging unit. A controller responsive to the manual operation unit for controlling the imaging unit and the signal converter to store the image data in the memory cartridge. When the first instruction signal from the operation unit is received, the controller reads out the control data from the memory cartridge. When the second instruction signal is received, the controller stores in the memory cartridge the image data from the signal converter depending upon the control data read out from the memory cartridge.
