Progressive scan, английский
- Video signals are generated using horizontal lines. progressive scan, also referred to as non-interlaced scanning, draws every line of an image in sequence. the main advantage with progressive scan is that motion appears smoother and more realistic.
- Ccd design that allows the acquisition of both odd and even fields at the same time. progressive scan makes full vertical resolution possible in donpisha mode. rgb (red, green, blue) the primary colors of light that produce a color video image. in video, rgb refers to a system in which these three primary colors are kept isolated and delivered from the source to the display device over separate wires. this system results in high-quality pictures. rgb signals are used in some broadcast video equipment and computers.
- Term used to describe an image sensor that gathers its data and processes each scan line one after another in sequence. see also interlaced for the other method.
- The method of displaying a video image one full frame at a time by scanning each line of an image in sequential order. videos displayed using progressive scan contain fewer motion artifacts and are generally smoother and more stable than interlaced scan display. progressive scan is a feature of computer monitors, many dvds, and most hdtvs.
