- electronic image stabilization
Abbreviated as EIS, electronic image stabilization uses electronic processing to control image stability. If the device sensors detect camera shake, EIS responds by slightly moving the image so that it remains in the same place on the CCD. Electronic image stabilization may result in a decrease in picture resolution. Contrast with optical image stabilization (OIS).
- electronic paper
Invented by Xerox at Xerox PARC, electronic paper (also known as epaper) is made from a display technology called gyricon. A gyricon sheet is a thin piece of transparent plastic that contains millions of small beads. Each bead–half white half black–is contained in an oil-filled cavity and is free to rotate within its cavity. Epaper […]
