The invention discloses a ghost weakening system and a ghost weakening method for electrophoretic electronic paper. The ghost weakening system for the electrophoretic electronic paper comprises a maincontrol module, a camera module, a display module, a storage module, a driving module and a PC terminal. The weakening method for the ghost weakening system comprises the steps that the camera moduleshoots an image of the electronic paper display screen and stores the image in the storage module; image preprocessing is carried out on an image through a PC (Personal Computer) end, wherein the image preprocessing comprises primary gray scale transformation, histogram equalization, secondary gray scale transformation, binaryzation and median filtering; acquiring an image, then performing edgeextraction on the image, cutting out an area with characters, performing character recognition, and finally reversely driving the recognized characters once through a driving module to weaken a ghostphenomenon. According to the invention, the characters of the image ghosting are recognized and are reversely driven by the driving module once, so that the effect of weakening the ghosting is achieved, and the reading experience of a user is greatly improved.
