Negative Effects of Motion Blur
In televised sports, where conventional cameras expose pictures 25 or 30 times per second, motion blur can be inconvenient because it obscures the exact position of a projectile or athlete in slow motion. For this reason special cameras are often used which eliminate motion blurring by taking rapid exposures on the order of 1/1000 of a second, and then transmitting them over the course of the next 1/25 or 1/30 of a second. Although this gives sharper slow motion replays it can look strange at normal speed because the eye expects to see motion blurring and does not.
Conversely, extra motion blur can unavoidably occur on displays when it is not desired. This occurs with some video displays (especially LCD) that exhibits motion blur during fast motion. This can lead to more perceived motion blurring above and beyond the pre-existing motion blur in the video material. See display motion blur.
Sometimes, motion blur can be removed from images with the help of deconvolution.

Holding their tattered frocks, thro’an airy maze
Of motion lightly threaded with nimble feet
Dance sedately; face to face they gaze,
Their eyes shining, grave with a perfect pleasure.”

Would blur no whisper, spoil no expression.”
