The Exposure Setting can be found under this path: Camera> Exposure.
The exposure is the amount of light received by the image sensor and is
determined by the width of lens diaphragm opening, the amount of exposure
by the sensor (shutter speed) and other exposure parameters. With this item,
users can define how the Auto Exposure function works.
Each exposure mode is specified as follows:
