Robert M. Case
is the developer of the ReadAllOvertm imaging system and file format (.rao).
Covered by three
issued and two pending U.S. patents, ReadAllOver is based on digital halftoning
that may be easily compressed for transmission and storage.
In contrast to
other halftoning methods, ReadAllOver balances abrupt edge detail with smooth
transitions, enabling typography and images to be processed simultaneously.
images were sampled at 200 ppi for output at 100 ppi. Compressed output is 1.6
bits-per-input pixel with a Structural SIMilarity (SSIM) index of 0.88.
system is positioned as an eBook file format competitor to .pdf, .jpg and .jp2.
Because of its novelty, ReadAllOver easily may be coupled with DRM and
just-in-time delivery to “always-on” client devices for the rendering of complex
seen as a value-added software component to a dedicated eBook hardware device
offered by a major book retailer.
