● Maximum correction: 32
● The white-spot correction feature of this
unit does not guarantee the correction of
all white spots.
Depending on the characteristic of white
spots, correction may not be possible.
● When performing white-spot correction,
accurate data may not be achieved in case
of highly detailed pixels since correction is
made using the information of surrounding
pixels.
● The result of white-spot correction is
maintained until the next correction is
performed.
