| Abstract: | In order to solve the problem that the flat panel display(FPD) can not present the low grayscale of image information finely and smoothly when the ambient brightness is relatively low,a dynamic nonlinear transformation algorithm based on Weber-law was proposed.A corresponding model of dynamic nonlinear transformation was constructed based on Weber-law.The realization steps of the algorithm were illustrated.This algorithm was applied in a LED display panel whose resolution is 640×480,and a group ... |
