measures the light in a specific
area of the image photographed and adjusts the shutter exposure time for the appropriate brightness of the
image. This corresponds to brightness changes outdoors (fog, time and changes in the weather).
The response speed for the automatic exposure is set to be slower and so this cannot be used during rapid
changes in brightness (strobe lights or explosions and the like).
When using the automatic exposure control, the shutter exposure time is adjusted between the shortest
exposure time and the exposure time set as a SHUTTER item. If the time stamp is ON, the value of the
shutter exposure time for the recorded frame is saved for each frame.
