PineappleQc Posted January 23, 2009 Share Posted January 23, 2009 heyalls! well i've been thinking about this for a while now, how come movies, pictures and others can be enlarged loselessly so easily using a projector? For all i know (i'm no expert) they aren't vectors, so i was wondering if it was possible to replicate this to enlarge digital pictures without any quality loss. I know for example my scanner will often scan a piece of paper and then save it much larger than it was in real life, and then i can even print it and i get to have a larger version just like that (although i never tried to scan the digital picture over and over...). Anyways, just throwing ideas like that, tell me what you think! -Ananas Quote "Ah, i love it when huge pineapples try to take over the world, it makes me sentimental :')" -Stephan Link to comment Share on other sites More sharing options...
david.atwell Posted January 23, 2009 Share Posted January 23, 2009 It doesn't. Get up really close to it: there are just as many pixels, they're all just an inch wide. :-) You can replicate the same effect by getting really, really close to your computer screen. Get a magnifying glass maybe. A projector isn't any more magical than a computer monitor: it can't make pixels up, either. :-P In fact, a projector is just a computer screen, inverted to make it huge.

PineappleQc Posted January 24, 2009 Author Share Posted January 24, 2009 okay, thanks for explaining, and what about those filmprojectors, like in the cinemas (although it's not very used anymore but anyways... ) or cameras, are all of those images vectors? that would be surprising... http://www.bombsite.com/images/attachme ... 1_body.jpg granted, they might just be pixelated but since we're sitting far from the image.... mmh...

david.atwell Posted January 25, 2009 Share Posted January 25, 2009 No. They're analog images. No pixels, no vectors. :-) Old school.
