What is motion blur?
Motion blur is the apparent streaking of rapidly moving objects in a still image or a sequence of images such as a movie or animation. It results when the image being recorded changes during the recording of a single exposure, either due to rapid movement or long exposure.
Screen motion blur, also called HDTV blur and FLATSCREEN motion blur, is a set of many different artifacts that is frequently available on modern consumer hi-definition television set sets and smooth panel displays for computer systems.
Many motion blur factors have existed for years in film and video (e. g. slow camera shutter release speed). The emergence of digital video, and HIGH DEFINITION TV display technologies, introduced many additional factors that now contribute to motion obnubilate. The following factors are often the primary or supplementary reasons behind perceived motion obnubilate in video. In many cases, multiple factors can occur at the same time within the complete string, from the original multimedia or broadcast, all the way to the recipient end.
Pixel response time on LCD displays (motion blur caused by gradual pixel response time)
More affordable camera shutter speeds common in Hollywood production motion pictures (blur in this article of the film), and common in miniaturized camera detectors that require more light.
Blur from eye monitoring fast-moving objects on sample-and-hold LCD, plasma, or microdisplay.
Resolution resampling (blur due to resizing image to fit the native resolution of the HDTV); not a movement blur.
Deinterlacing by the display, and telecine control by studios. These techniques can soften images, and introduce motion-speed irregularities.
Compression artifacts, within digital online video streams, can contribute additional blur during fast movement.
What is motion blur? Motion blur has recently been a more severe problem for LCD displays, anticipated to their sample-and-hold characteristics. Even in situations when pixel response time is very brief, motion blur remains problems because their pixels continue to be lit, unlike CRT phosphors that merely flash in brief. Reducing the time an LCD pixel is lighted, can be accomplished via killing the backlight for part of an invigorate. This reduces motion blur due to eye tracking by reducing the time the backlight is on. Additionally, strobed backlights can even be combined along with motion interpolation to minimize
