How does resolution upscaling and remastering works in retro video games and movies?
In: Technology
Imagine you have 5 dots on a piece of paper, in a line. You could take a pencil and draw that line through the 5 dots. Now, looking at your line, you could draw lots more dots on the same line – maybe 50 or 100! A computer can use math to look at an existing picture/shape/whatever and basically compute where to add new dots (ie upscale resolution) – the same as you did with your line and pencil.
