1. An electronic still-video camera comprising:
- image pick-up device for picking up an image of a subject and outputting a video signal representing the image of the subject obtained;
recording signal processor, including a frame memory, for converting the video signal outputted by said image pick-up device into digital image data suited for storage in a memory device, and for compressing the digital image data;
a connector, in and from which a first memory cartridge is capable of being loaded and unloaded at will, said first memory cartridge incorporating an external memory for storing the compressed image data;
a sensor for sensing that the first memory cartridge has been connected to said connector;
determining device for determining that compressed image data can no longer be recorded in the first memory cartridge connected to said connector;
a display for displaying a message requesting replacement of the first memory cartridge in response to the determining device determining that compressed image data can no longer be recorded in the first memory cartridge,wherein, said sensor senses unloading of the first memory cartridge after display of the message and senses loading of a second memory cartridge after sensing unloading of the first memory cartridge;
a controller, after the digital image data has been stored temporarily in the frame memory and subsequent to the sensor sensing the loading of the second memory cartridge, for confirming that the second memory cartridge includes available memory storage space, and for controlling the writing of the digital image data from the frame memory to the second memory cartridge upon confirming that the second memory cartridge includes available memory storage space; and
a device for cancelling automatic turn-off of power in response to the message requesting replacement of the first memory cartridge being displayed by said display.

Abstract
An electronic still-video camera is provided capable of preserving image data having a quantity which is greater than the storage capacity of a memory cartridge (memory card) loaded in the camera. Besides being capable of receiving an external memory in a memory cartridge loaded in the camera, the camera incorporates an internal memory. Image data obtained as a result of photography is stored in either the internal memory or the external memory, depending upon which memory has been selected by a memory selection switch.
