Only for denoising does it do multiple exposure for median frame blending. I have worked on enough Apple TV+ shows and been required to shoot scenes with iPhones and iPads for VFX I can tell you the exact mechanism used for every option Apple gives including SDI adapters to external recorders. There is no image stitching accept for panos and even that is more complicated and more similar to how all film panos work accept an iPhone
Is using a full frame and fractal image blending for the joining.

The Cirkut camera certainly had its share of distortion issues, And it would not apply to motion picture cameras. But you're right. It's hairsplitting. The iphone actually shoots multiple frames and stitches them. It makes the equivalent of a very short movie actually.On Tue, Dec 26, 2023 at I 6:05 PM Randy Little <randyslittle@xxxxxxxxx> DIwroThats the same as saying every slit scan camera isnt a camera. Its some real hair splitting. It would alao imply that almost no film movie camera is a camera since they depend on a rolling shutter. Or the Cirkut camera of the early 1900sAlso its not fancy stitching algorithm its a simple x,y value with a R,g or B value attached per photo site. The demosaic is pretty fancy.Randy S. Little

The phone shoots many images as the scan passes and has stitching algorithms to correct this effect but it doesn't always give a good result... as The Western Journal article, I believe, demonstrates.On Tue, Dec 26, 2023 at 5:21 PM Herschel Mair <herschphoto@xxxxxxxxx> wrote:Kind words but really it's just a guess.On Tue, Dec 26, 2023 at 12:55 PM Lew Schwartz <lew1716@xxxxxxxxx> wrote:Don't believe Herschel for a second.
