“pixilation” vs. “pixelation”

Nouns, Versus

I saw a technical document refer to “pixilation” when it should have referred to “pixelation” instead.

Problem:
The nouns “pixilation” and “pixelation” are not synonyms.

Explanation:
I was reviewing some technical documents about a month ago.

They referred to “picture pixilation” in the television signals coming from various set-top boxes.

They should have used “pixelation” — spelled P-I-X-E-L-A-T-I-O-N — instead of “pixilation” — spelled P-I-X-I-L-A-T-I-O-N.

The noun “pixie” — spelled P-I-X-I-E — was coined in the early 1600s to refer to a sprite or fairy, especially a mischievous one.

So the primary meaning of the noun “pixilation” is the state or quality of being pixilated — spelled P-I-X-I-L-A-T-E-D — which is an Americanism from the mid-1800s that combines the word “pixie” with the word “titillated” to mean amusingly silly, prankish, or whimsical.

The noun “pixel” — spelled P-I-X-E-L — was coined in the late 1960s as something of a contraction of “picture element” to refer to the smallest element of an image that can be managed and presented by a video display system.

And the primary meaning of the noun “pixelation” is the display of a digitized image such that the pattern of pixels is obvious to the naked eye.

Solution:
Think “pixie” when using “pixilation”. Think “pixel” when using “pixelation”.
