4. Various Modes of Shooting (continued)

White Spot Correction

As a peculiar common characteristic of CCD, white spots may appear on the screen when it is operated
under high temperature or when shutter speed is prolonged during use.
This unit comes with a white spot correction feature to reduce this phenomenon.
How To Use
Detection of White Spots
The quantity and size of white spots differ with the temperature and shutter speed during use. Before
using the white spot correction feature, it will thus be necessary to detect the position of the white spots
under the conditions of use.
