An electronic camera includes a mode change switch. This mode change switch selects
a still image recording mode to record 1 scene of an image signal to a recording
medium, and a continuous image recording mode to record a plurality of scenes of
continuous image signals to the memory medium. In the still recording mode, an
battery remaining capacity goes below 5%, the shutter button is disabled in operation.
In the continuous image recording mode, when the battery remaining capacity goes
below 25%, the shutter button is disabled in operation. These threshold values
are related to a consumed power required for recording the image signal taken in
each of the modes.
