About White-spot correction
Others
Usage
Switch on the camera power supply and wait
for at least 30 minutes.
1.
Remove the dome cover.
2.
Cover the lens surface using a black
sheet of paper, etc. so that light does
not enter the lens.
3.
Press and hold the SPOT CORRECTION
button on the unit for more than 2
seconds.
• White-spot correction will start.
Correction may take several seconds
for completion.
As a general characteristic unique to CCDs, white-spots may appear on the screen with age.
In order to reduce this phenomenon, this unit is equipped with a white-spot correction feature.
Memo:
• The white-spot correction feature of this unit does not guarantee the correction of all
white spots.
Maximum correction: less than 16 ~ 32 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.
