Abstract

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.

Description

technical field [0001] The invention relates to the technical field of image and character recognition, in particular to an electrophoretic electronic paper ghost reduction system and reduction method. Background technique [0002] Electrophoretic electronic paper has the characteristics of ultra-low power consumption, thinness, and flexibility. It is widely used in display products such as electrophoretic e-book readers, electrophoretic electronic labels, and electrophoretic electronic billboards. However, when refreshing electronic paper products, there will be The ghosting of the last image, the ghosting phenomenon will greatly affect the user's reading experience; currently, there is no relatively complete method for reducing the ghosting phenomenon of electronic paper, so it is necessary to design a system and method for reducing ghosting. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an elect...
