The new iPad to better handle the normal resolution images

1 pointseltados14y ago2 comments

I just got my new iPad (it is actually my first one so I have nothing to compare again ) and I have been like everybody blown away by the quality of the new screen. But after few minutes i leave apple wonder world, launch safari and go online and as everybody is blown away about how crap the images look. Every image is so blurry.

I have read many article online on how web developer could deliver high res images etc ... But my question is the following , wouldnt it possible to have better anti aliasing system in ios to properly handle the normal resolution images? At the end of the day the 1 normal res pixel should only had to be replaced by 4 high res pixel of the exact same color. But obviously it is not what is happening here otherwise we would see this blurry effect.

If anyone has any information about this topic I would thrilled to read about it.

The problem is coming up with a scaling algorithm that works ideally on every kind of image; it simply can't be done. Some methods work better for some images, and other methods work better on others. Wikipedia has a good overview: http://en.wikipedia.org/wiki/Image_scaling

The scaling in the browser has to work on any arbitrary resizing, not just 2x. A simple pixel doubling only works in one specific circumstance, and would be inconsistent with other scaled images.

Thank you very much, execellent read. I still think / hope that there is room for apple to improve the way they do their image scaling in iOS for the retina display. I think it is not sustenable to expect all the web to support high res images everywhere in the short to medium future.
