In photography and film, motion blur is referred to as a zonal limited blurring that occurs in pictures of moving objects.
With LCD monitors, motion blur must be distinguished from ghosting. If a monitor shows ghosting, one can see little trail pulled along behind moving objects. You can find more information on the topic of ghosting in our FAQ .
Whereas motion blur merely results in the picture loosing focus when fast movements or camera pannings are to be displayed. All of the LCD monitors that are currently available still have this problem - even though to varying degrees. Those LCDs that are capable of drawing images faster generally produce better results in this regard.
