I’ve been playing around with my method for enlarging images pass four times its original size without losing any detail by add sub pixels to the image. But depending on the image, my method could be changed to better suite an image for better results.

In this method, sub pixels are generated not just to the original image, but to a high light level of the image. The result is an image that does not lose dark details.
