COLOR AC-PDP ENHANCEMENT OF LOW LEVELS IMAGE QUALITY WITH DYNAMIC MODIFYING SUB-FIELDS CODE

Based on the ＂Grayscales average distribution＂ method which equally distributes the input gray levels to output gray levels, three improved methods named： ＂Reduce the gray range expressed by the less significant subfields＂, ＂Low levels preset＂ and ＂Modify the exponent of inverse-gamma function＂ are proposed in this paper. Using these methods, the inverse-gamma relation subfields code can be obtained easily which can improve the low level expressions of AC-PDP. And a program, ＂ gray scales distribution validate program＂, which can enhance the expressions of the demanded gray levels range, is also proposed in this paper.
