Display drive method, display, and program therefor

A method of driving a display, comprising:

• correcting a grayscale level of at least one pixel to facilitate a transition from a current grayscale level to a desired grayscale level, the correcting including correcting a grayscale level of at least one pixel to facilitate a transition from a current grayscale level to a next grayscale level;
• reducing high frequency components in a spatial domain of the corrected at least one pixel;
• calculating a mean difference in grayscale level between the at least one pixel and a plurality of pixels of a first group of pixels, located on a segment having a midpoint at the at least one pixel and located to one direction of the at least one pixel, calculating a mean difference in grayscale level between the at least one pixel and a plurality of the first group of pixels located to another direction of the at least one pixel, and determining that the at least one pixel has an unacceptable grayscale level upon the mean differences having different signs;
• calculating a second mean of corrected grayscale levels of a second group of pixels in proximity to the at least one pixel upon the at least one pixel being determined to have an unacceptable grayscale level;
• and
• changing the unacceptable grayscale level to a grayscale level equal to the second mean.

A display, comprising:

• a first correction section, adapted to correct a grayscale level of at least one pixel to facilitate a transition from a current grayscale level to a desired grayscale level;
• a second correction section, adapted to reduce high frequency components in a spatial domain of the corrected at least one pixel;
• and
• a determination section, adapted to calculate a first mean of corrected grayscale levels of a first group of pixels in proximity to the corrected at least one pixel and adapted to determine whether the corrected at least one pixel has an unacceptable grayscale level, upon the first mean differing from a grayscale level of the corrected at least one pixel by more than a threshold value;
• wherein the second correction section is further adapted to calculate a second mean of corrected grayscale levels of a second group of pixels in proximity to the corrected at least one pixel, upon the determination section determining that the corrected at least one pixel has an unacceptable grayscale level, and adapted to change the unacceptable grayscale level of the corrected at least one pixel, to a grayscale level equal to the second mean.
