Each JND value corresponding to each obtained luminance value to be assigned to each unit gradation of a panel is obtained. A pixel value corresponding to the each JND value is obtained for each of the unit gradations of the panel. A threshold ε is obtained by inverse gamma-correcting the ratio between discernible JND values corresponding to the unit gradations of the panel and the maximum output value of the panel. Linear function-based approximations are obtained using least squares. The threshold ε is determined as an increasing function of a pixel value on the basis of the allowable number of JND steps. The threshold ε is changed using this function. The threshold ε can be changed according to the center pixel value. | 04-30-2015 |
