The issue focused on digital cameras for smartphones and tablets. Since iPhones use sensors with pixels only three times smaller than those found in cameras like the Nikon D810, phones using smartphones without processors larger than 64 bits may lack sufficient computational power to capture digital photos that meet digital photographers' expectations of sharpness and contrast. This technology allows photographs taken with smartphones and tablets to display significantly sharper images than comparable pictures taken with cameras equipped with processors larger than 128 bits. But devices equipped with CPUs smaller than 256 bits cannot render digital photos
