That isn't really true...
Have you ever tried it? Logically you aren't gaining any more pixels by converting it from res A to res B and then back to res A so there isn't any real beneficial type effects happening (if it was the case then why wouldn't they do something like this on GPUs before outputting to the display, scale the image up and then back down?). It doesn't make it "smoother" because the pixel count is the same -- you're going to have just as many edges as you started with.
It is a far cry from adding any sort of AA type effects -- it usually makes the image look worse than the original, not better.
Bobber .
You have an image that was a ) taken at 720p compressed and then upscalled to 1080p b) taken at 720p left untouched and upscaled to 1080p then compressed and then c) taken at 1080p and compressed d) was downscaled with the jpg artifacts and smoothing from compresion back down to roughly a million less pixels .
We also don't know what program was used to resize it and what was done to the image during the resize

well they are most likely the 1080p image (or if correct the original 720p image) and then downscaled . Which will only make it look better as the pixc is smaller and contains less pixels3roxor said:So what IS the right picture scaleLooking at the OFFICIAL source those ingame pics are alot smaller and look nice and detailed + have no real visible jaggies..
You can gain or lose smoothing by downsampling depending on algorithm. A straight Bilinear resmaple of the 1080p pics provided still had exaggerated size of the jaggies (an interpolated extra pixel's width). You can't ably obtain the original data without knowing what the source resolution was and 'reverse-engineering' the scaling really.
Probably best to wait for official pics from some source. Can't honestly see the point to the pics provided. Larger files, more BW, for inferior quality.

Assuming these shots are actually from 720p (which is a safe bet) and then upscaled to 1080p, scaling them back down to 720p isn't going to get you better shots unless they are using some real fancy-ass upscalers (which from the screenshots, they clearly aren't, as the jaggies are roughly 2 pixels across instead of 1, which they should and would be had a good upscaler actually been present).
How you guys can claim, looking at those screenshots, that some magic voodoo is being done with scaling is amazing. These aren't native 1080p screenshots and they weren't scaled very well at all -- scaling them back down is not going to gain you anything worth while that wasn't present in the original since the upscaling was done crappily to begin with (the clarity you lose is more detrimental than the few pixels here and there that get a free glazing).
PC-Engine: I'm not sure if you just wanted to argue semantics, but it is pretty clear that something like Faroudja offers wasn't used here.

Anyone with a paint package can try for themselves to regenerate the original from an upscaled image. Create a 256x256 pixel bitmap and draw some squiggles with good jaggies. Now upscale 150% (379x279 pixels) using whatever algorithm you fancy from those provided. Now downscale to 66% (256x256 pixels) with whatever downsampling method you care.
Anyone who can restore the original data this way wins a gold star if the mention how they did it (which upsacle/downscale algorithms they used). If the ratio between pictures isn't a power of 2, pixels get splurged in both and downscaling, so you're looking at a pixelated mess no matter what you do.
