[Galaxy J Series 2017] Why I got black dots and the video screen twinkles while recording video under fluorescent lamp?

Last Update date : 2017.07.04

 

This is a normal phenomenon related to flicker of light source that occurs
when the light source taking the form of a flashing frequency of the fluorescent lamp
to the camera
. Flicker phenomenon can mainly be generated at a shutter speed of 1/120
or more and it occurs in the characteristics of the CMOS sensor. It is not a product defect.

 

This is normal operation which can happen on all camera with CMOS sensor
and it’s caused by CMOS sensor’s
original specification.
