Image persistence, or image retention, is a phenomenon in LCD and plasma displays where unwanted visual information is shown which corresponds to a previous state of the display.

When the same image is displayed on a CRT screen for long periods, the properties of the exposed areas of the phosphor coating on the inside of the screen gradually and permanently change, eventually leading to a darkened shadow or "ghost" image on the screen, called a screen burn-in.

Some camcorders and digital microscopes employ separate color channel sensors (usually RGB = red, green, blue) sensors.. Pixel shifting may be implemented for one or more of these sensors by moving such a sensor by a fraction of a pixel (or even a whole pixel value) in both x- and y-direction.
