HDTV blur

HDTV blur is a common term used to describe a number of different artifacts on modern consumer high-definition television sets.

The following factors are generally the primary or secondary causes of HDTV blur; in some cases more than one of these factors may be in play at the studio or receiver end of the transmission chain.

  • Pixel response time on LCD displays (blur in the color response of the active pixel)
  • Slower camera shutter speeds common in Hollywood production films (blur in the content of the film)
  • Blur from eye tracking fast moving objects on sample-and-hold LCD, plasma, or microdisplay.[1]
  • Resolution resampling (blur due to resizing image to fit the native resolution of the HDTV)
  • Blur due to 3:2 pulldown and/or motion-speed irregularities in framerate conversions from film to video
