> It's something of an open question how good smart sharpening algorithms can get True, but you're strictly limited by what I assume are microscopic gate capacitances on pixels that small. The maximum number of electrons in an iphone pixel are probably less than 10k, leading to less than 7 bits of maximum theoretical entropy per px from shot noise limits. This is going to sharply curtail (no pun intended) your ability to "back out" airy disk overlap.
