Is time-lapse photography the same as shifting axis photography? What is the principle? Why does the scene look so small, like a toy?

Delay is equivalent to taking a selfie.

You must talk about moving axes. In an ordinary camera, the optical axis of the lens is perpendicular to the film plane and at the center. Shifting the axis is to move the lens optical axis away from the center of the film. Moving the axis can't change the perspective relationship or focal plane, but it can capture the position that can't be captured normally.
