AUTOMATIC LUMINANCE CONTROL METHOD OF VIDEO CONFERENCE SYSTEM |
摘要 |
PURPOSE: An automatic luminance control method is provided to facilitate the luminance control by automatically tracing the luminance when a state decision variable value is in the maximum CONSTITUTION: A method comprises the steps of: initializing variable values(S210); substituting a state decision variable value with a comparison variable value(S220); increasing an initially set luminance variable value by one level(S225); producing frequency data by each pixel of an image inputted through a video input unit with an application of the increased luminance value(S230); calculating an average value of the produced frequency data by pixel(S235); and low-pass-filtering the produced frequency data by pixel(S240).
