Still video camera including detachably attachable external memory

A still video camera comprising:

• an image pickup device;
• a non-volatile memory, incorporated in said camera, in which an image taken by said image pickup device can be recorded or an image recorded therein can be erased;
• an external memory, which is detachably attached to said camera, and which can store therein said image taken by said image pickup device;
• connecting means to which said external memory is electrically connected;
• and,
• recording means for recording image signals of said image taken by said image pickup device in said non-volatile memory or said external memory,
• wherein if said external memory is connected by said connecting means during recording of said image signals in said non-volatile memory, said recording means stops recording said image signals in said non-volatile memory, and records said image signals in said external memory.

A still video camera comprising:

• an image pickup device;
• a non-volatile memory, incorporated in said camera, in which an image taken by said image pickup device can be recorded or an image recorded therein can be erased;
• an external memory, which is detachably attached to said camera, and which can store therein said image taken by said image pickup device;
• connecting means to which said external memory is electrically connected;
• first remaining capacity detecting means for detecting a remaining storage capacity of said external memory;
• and,
• recording means for recording image signals of the image taken by said image pickup device in said non-volatile memory or said external memory,
• wherein if said external memory is connected with said connecting means, and if said first remaining capacity detecting means detects that a storage capacity necessary to record the image signals for at least one image remains in said external memory during recording of said image signals in said non-volatile memory, said recording means stops recording said image signals in said non-volatile memory, and records said image signals in said external memory.

A still video camera comprising:

• an image pickup device;
• a non-volatile memory incorporated in said camera, in which an image taken by said image pickup device can be recorded or an image recorded therein can be erased, said non-volatile memory being provided with a plurality of recording unit areas;
• an external memory, which is detachably attached to said camera, and which can store therein said image taken by said image pickup device;
• connecting means to which said external memory is electrically connected;
• recording means for recording image signals of the image taken by said image pickup device in said non-volatile memory or said external memory;
• erasing means for erasing said image signals recorded in at least said non-volatile memory;
• and,
• record judging means for detecting a number of erasing operations performed for each recording unit area of said non-volatile memory to thereby judge whether data can be recorded in said recording unit area,
• wherein said recording means performs or prohibits said recording of said image signals in one recording unit area, in accordance with a judgment of said record judging means.

A still video camera comprising:

• an image pickup device;
• a non-volatile memory, incorporated in said camera, in which an image taken by said image pickup device can be recorded or an image recorded therein can be erased, said non-volatile memory being provided with a plurality of recording unit areas;
• recording means for recording image signals of said image taken by said image pickup device in said non-volatile memory along with recording time;
• and,
• recording time allotting means for allotting a frame number to said image signals recorded in said non-volatile memory in which said image signals has been recorded, in order of said recording time.
