4. Shooting a computer monitor screen (cont'd) White spot compensation One of the inherent, general characteristics of CCDs is that white spots may appear in the image at slow shutter speeds or during shooting at high temperatures. To moderate this phenomenon, this camera is provided with a white spot compensation function. In the digital output mode, white spot adjustment should be performed using the special application software [KY-LINK]. How to use Ⅲ White spot detection Because the number of spots and their size differ with the temperature and shutter speed, etc., it is necessary to detect the positions of the white spots under the conditions of use before the white spot compensation is used. 1. Make the settings under the conditions at which the unit is to be used (ambient temperature and shutter speed, etc.). 2. Prevent light from entering the CCD by closing the lens iris, etc. Inside window ʦ.&/6ʧ UP/AW MENU SET DOWN 1 2 34 ʦ61ʧ ʦ4&5ʧ ʦ%08/ʧ 3.
