Cleaning the CMOS Sensor
If the CMOS sensor becomes dirty or dusty, shadows may appear in the 
image in certain situations such as when shooting against a white 
background. This indicates that the CMOS sensor must be cleaned.
Dust adhering to the CMOS sensor is removed by applying ultrasonic 
vibrations to the filter on the front surface of the CMOS sensor.
