(Not to be confused with Pixilation, which is the Stop Motion animation of live actors.) Video editors alter a section of the screen by averaging or mildly scrambling the color values of the image across larger areas than the original pixels, producing a blocky effect that obscures detail but retains much of the original hue and contour information. A black square is still used in some cases. When played for laughs, the censor box or pixellation instantly becomes a Gag Censor (for example, superimposing a crown over the crotch of a streaker during a royal visit in Britain).
