Abstract
A data transition minimization method includes exclusive-NORing inputted nth image data (where n is a natural number) and (n−m)th image data (where m is a natural number smaller than n) expressing the same color as that of the nth image data to generate transition information data; generating inversion data indicative of inversion information by inverting all bits included in the transition information data and adding a unit bit having the logic value ‘1’ to the inverted transition information data when the number of unit bits having a logic value ‘1’ in the transition information data is larger than the number of unit bits having a logic value ‘0’ in the transition information data, and adding a unit bit having the logic value ‘0’ to the transition information data when the number of unit bits having the logic value ‘1’ in the transition information data is equal to or smaller than the number of unit bits having the logic value ‘0’ in the transition information data; exclusive-NORing the transition information data with the inversion data added and corrected image data of (n−1)th image data to generate corrected image data of the nth image data, and supplying the generated correct…
