“It seems pretty clear that smartphones have become the point-and-shoots of our time.  The latest smartphone cams on the market have resolutions up to 41 megapixels, well more than the 10Mp of my old Canon PowerShot S90.  Even the average top-end smartphone sports a lens that delivers at least 16Mp.”

“So, other than driving the point-and-shoot guys out of business, what have they achieved, these super-cam smartphones?  Well, a lot, and they’re going to do more.”

“Now, 16Mp will support any format of the new 4K displays, which have roughly 4,000 pixels along the horizontal edge.  In fact, depending on the standard, they can vary from 3,840 to 5,120, and have anywhere from ~7Mp up to ~16.3Mp total, but the standard for ultra high definition television (UHDTV) uses just a bit more than 8Mp.”
