Abstract
A method, system and apparatus for detecting a sub-pixel pair susceptible of producing a flicker event in an image from a video signal source displayed on a liquid crystal display (LCD) unit is described. A two dimensional flicker pattern analysis is performed on a selected group of sub-pixels some of which are included in a first plurality of sub-pixels that includes a first current sub-pixel and a first next sub-pixel included in a first video frameline and a remainder of which are included in a second plurality of sub-pixels included in a second video frameline that is received, in real time, from the video signal source that includes a second current sub-pixel and a second current sub-pixel.
