The electrophoretic display (EPD) has dominated the panel used in electronic readers. However, getting more than 16 observable gray levels on an EPD is still a big challenge. A true color image should be converted into a 16 gray level image for displaying it on an EPD. In this paper, we propose an image processing tool that combines contrast enhancement and the modified Nasik pattern halftoning to...
The electrophoretic display (EPD) has become the main stream of the panel used in consumer electronic readers. However, getting more than 16 gray levels on an EPD is still a big challenge. In this paper, we propose an image processing tool that combines contrast enhancement and modified error diffusion halftoning to deal with the problems on the image conversion process. The experimental results show...
