Afterimage is a computer graphics effect used by video games. The effect takes the bright parts of a rendered image of the scene, and then fades in a motion blur style fashion as the scene progresses. The result is that bright areas leave a fading trail when the camera is moving. Afterimage can be used to enhance blooming. In some games, the process is named light trail.
