Cleaning and checking the image pickup device
This camera incorporates a dust reduction function to keep dust from getting on the
image pickup device and to remove any dust or dirt from the image pickup device
surface with ultrasonic vibrations. The dust reduction function operates when the
camera is turned on.
The dust reduction function operates at the same time as the pixel mapping, which
checks the image pickup device and image processing circuitry. Since dust reduction
is activated every time the camera’s power is turned on, the camera should be held
upright for the dust reduction function to be effective.
Pixel Mapping - Checking the image processing functions
The pixel mapping feature allows the camera to check and adjust the image pickup
device and image processing functions. For best results, wait at least a minute after
shooting and playback have ended before performing pixel mapping.
