resizing Image resizing/resampling info

I am looking to enlarge some images, both video and static, for additional processing.

I am looking for a dumb option: I want one red pixel to turn into a set of 4 red pixels, and the blue pixel beside it to become  4 blue pixels.

no colour blending, estimating, nothing just each pixel doubled in length and width.

a big blocky picture that I can post-process.

I have no idea what word I am looking for.

Isn't that basically what happens when you upscale something in say Photoshop.
