Color-spoke processing apparatus and method usable with sequential color display devices

摘要

A spoke-processing apparatus usable with sequential color display devices using spokes depending on a color saturation and a luminance of an input color signal. A spoke-processing method usable in sequential color display devices using the spokes includes calculating a color saturation of an input color signal and determining whether the calculated color saturation is less than or equal to a first threshold, determining whether the input color signal has a luminance that is greater than a second threshold when the calculated color saturation is determined to be less than or equal to the first threshold, determining whether to increase the luminance of the input color signal using spoke areas when the luminance of the color input signal is greater than the second threshold and the calculated color saturation is less than or equal to the first threshold and calculating a signal adjustment ratio to intensify or lessen the input color signal based on whether the luminance of the input color signal is increased by the spoke areas, and outputting an output color signal having luminance of respective color components intensified or lessened according to the calculated signal adjustment ratio.
