I know that iPhones have great cameras but what technology underlies great phone cameras? Intuitively, the number of megapixels is only a tiny part of the story.
From wikipedia, I can see the iphone 8 for example has the following features.
8: 12 MP with six-element lens, quad-LED "True Tone" flash with Slow Sync, autofocus, IR filter, Burst mode, f/1.8 aperture, 4K video recording at 24, 30, or 60 fps or 1080p at 30 or 60 fps, slow-motion video (1080p at 120 or 240 fps, timelapse with stabilization, panorama, facial recognition, digital image stabilization, optical image stabilization 8 Plus: In addition to above: A telephoto lens with 2× optical zoom / 10× digital zoom, f/2.8 aperture. Portrait Lighting (beta)
Which ones are important for a great camera? I would guess
- six-element lens
- f/2.8 aperture
My ultimate intention is to find other phones which have similar spec cameras to the iphone (but cheaper).
