Motion blur reduction for LCD video/graphics processors

A computer program product comprising a non-transitory computer readable storage medium that stores computer-executable instructions that implement a method of reducing motion blur in a liquid crystal cell, the method comprising the steps of:

• converting a previous picture frame from an RGB color space into a YUV color space;
• storing a luminance component in the YUV color space related to the previous picture frame;
• converting a current picture frame from an RGB color space into the YUV color space;
• determining an overdrive factor based on a difference between a luminance component in the current picture frame in the YUV color space and the stored luminance component;
• creating a modified luminance component by applying the overdrive factor only to the luminance component of the current picture frame in the YUV color space;
• and
• converting the modified luminance component and color components of the current picture frame back into an RGB color space for display in the liquid crystal cell;
• thereby increasing the transition speed from one luminance level to another.

A system for reducing motion blur in a liquid crystal cell, the system comprising:

• means for converting a previous picture frame from an RGB color space into a YUV color space;
• means for storing a luminance component in the YUV color space related to a the previous picture frame;
• means for converting a current picture frame from an RGB color space into the YUV color space;
• means for determining an overdrive factor based on a difference between a luminance component in said current picture frame in the YUV color space and the stored luminance component;
• means for creating a modified luminance component by applying a drive factor only to the luminance component of the current picture frame in the YUV color space;
• and
• converting the modified luminance component and color components of the current picture frame back into an RGB color space for display in the liquid crystal cell;
• thereby increasing the transition speed from one luminance level to another.
