In visual perception, flicker is a human-visible change in luminance of an illuminated surface or light source which can be due to fluctuations of the light source itself, or due to external causes such as due to rapid fluctuations in the voltage of the power supply (power-line flicker) or incompatibility with an external dimmer.
The 4th generation of LED tubes offers a solution to the flickering problem. The flickering is measured using so-called flicker index or flicker percentage value. Elimination of flickering allows high-quality video recording and slow motion capture, as well as certain machine vision applications in premises equipped with flicker-free lights. [3 ...
Power-line flicker is a visible change in brightness of a lamp due to rapid fluctuations in the voltage of the power supply. The voltage drop is generated over the source impedance of the grid by the changing load current of an equipment or facility. These fluctuations in time generate flicker.

This ability (plus built-in genlocking) resulted in the Amiga dominating the video production field until the mid-1990s, but the interlaced display mode caused flicker problems for more traditional PC applications where single-pixel detail is required, with "flicker-fixer" scan-doubler peripherals plus high-frequency RGB monitors (or Commodore ...
The pressure campaign trumped. The bloated congressional funding bill that faced a mass Republican revolt aided by President-elect Donald Trump has been scrapped, House Majority Leader Steve ...
Bill Belichick was announced as North Carolina's next head coach Wednesday in a shocking hire that will have ramifications on college football for years to come. It turns out the stunning move ...
As illustrated by a straight line on the chromaticity diagram, simple two-white blends will have a pink bias, becoming most severe in the middle. A small amount of green light, provided by another LED, could correct the problem. [38] Some products are RGBWW, i.e. RGBW with tunable white. [39] A final class of white LED with mixed light is dim ...
