Image Sensor Cleaning
Using camera controls during shutdown interrupts image sensor
cleaning.
If image sensor cleaning is performed several times in succession,
image sensor cleaning may be temporarily disabled to protect the
camera’s internal circuitry. Cleaning can be performed again after a
short wait.
