I take 2 images with the same position.

Photo mode: photo

Video mode with the flash is on: video

Why the image that I get from the video frame is more narrow and not blur than photo mode?

And can I take the image like the Video mode with Photo mode? I tried and I cannot take the image like that in Photo mode, if I move the iPhone closer, it cannot focus on the subject.

One is a straight on single-frame image from the phone. That is the native aspect ratio of the sensor which every pixel gets to contribute to the image.

The second uses a cropped area so that the phone can filter the image to account for motion of the phone which is why a few pixels are lost. By having those extra pixels and motion information, processing can be applied to make the output look sharper.

This is essentially a digital simulation of image stabilization.


It appears though that in video mode, the images are cropped. Here is a discussion with more in depth explanations than I can ever give. I hope it points you in the right direction.
