eInk e-readers

A developer has shared an approach for improving manga image quality on eInk devices, applying techniques such as two-dimensional discrete Fourier transforms and dithering to optimise grayscale output for e-paper displays. The work relates to the open-source Kindle Comic Converter project, which converts comics and manga for e-readers. Readers and hobbyists are discussing the trade-offs of signal processing tricks for low-resolution, low-color screens.
