Patent ID: 7474303

Claim:
A spoke-processing apparatus usable with sequential color display devices, comprising: a saturation calculation unit to calculate a color saturation of an input color signal and to determine whether the calculated color saturation is less than or equal to a first threshold; a luminance calculation unit to determine whether the input color signal has a luminance that is greater than a second threshold when the calculated color saturation is determined by the saturation calculation unit to be less than or equal to the first threshold; a signal intensifying/lessening ratio calculation unit to determine whether to increase the luminance of the input color signal using spoke areas according to the determination of the luminance calculation unit, and to calculate a signal adjustment ratio to intensify or to lessen the input color signal based on whether the luminance of the input color signal is increased by the spoke areas; and a spoke application unit to output an output color signal having luminance of respective color components intensified or lessened according to the calculated signal adjustment ratio.
