Abstract
A system for dynamic gamma correction of multi-scaled clocks and method therefor are provided, wherein multi-scaled clocks are applied to control the grayscale upon only one set of ramp voltage, so that the linearity of the gamma curve can be adjusted freely or to adjust the gamma correction strategy based on the image content or the user preference.
