This technology is used in digital TVs to produce a picture that fills the screen every 1/60th of a second. (By comparison, regular TV sets show only half of an interlaced picture every 1/60th of a second.) By virtually eliminating flicker and visible scan lines, a smoother picture is presented that looks more like actual movie film. Computer monitors also use progressive scanning to produce clear text that is easy to read. The progressive scan outputs on a DVD player can be connected only to digital TVs that have progressive scan inputs.
An image that is painted line by line in a continuous fashion. Compare to interlace scan which paints every other line, requiring two scans to create a complete image.
(1) A camera in which all rows of the sensor are exposed at the same time, and/or (2) A camera whose video output is not interlaced. Some cameras have a progressive scan sensor and interlaced video output, eliminating temporal shifts between fields but maintaining compatibility with interlaced monitors and frame grabbers. Compare with Interlace.
