Electrophoresis electronic paper ghost image detection system and method

Abstract

The invention discloses an electrophoresis electronic paper ghost image detection system and method. The electrophoresis electronic paper ghost image detection system comprises a main control module,a camera shooting module, a storage module, a display module and a PC, wherein the camera shooting module, the storage module and the display module are electrically connected with the main control module; and the PC is in communication connection with the main control module through the internet. An image of an electrophoresis electronic paper display screen is shot through the camera shooting module; the image is converted into a gray image; an optimal threshold value T of the image is calculated by utilizing a maximum inter-class variance method; whether a ghost image exists in the image ornot is judged by traversing gray values of all pixel points of the image to be compared with the optimal threshold value T; the system has the advantages of being simple in structure, convenient to operate and the like; whether a ghost image phenomenon exists in electrophoresis electronic paper or not can be well detected, so that the improvement and optimization can be carried out for the ghostimage phenomenon of the electronic paper; and therefore, the reading experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of image detection, in particular to an electrophoretic electronic paper ghost detection system and detection method. Background technique [0002] Electrophoretic electronic paper display has the characteristics of ultra-low energy consumption and paper-like display, and is widely used in display products such as electrophoretic e-book readers, electrophoretic electronic labels, and electrophoretic electronic billboards. The quality of electrophoretic electronic paper display depends on the An important factor of product quality. For example, when using an electrophoretic e-book reader, if ghost images often appear during the reading process, it will seriously affect the reader's viewing experience. In the prior art, there is no relatively perfect e-paper Ghosting detection system, therefore, it is necessary to design and develop a detection system for detecting the ghosting phenomenon of electronic paper, ...
