Many smart phones today are able to take panorama shots, by sweeping the camera from one direction to another.\
Assuming ideal pinhole optics and that the camera works like a slit scan, all straight lines of the object become what family of curves?
Assume that, mathematically speaking, all points of the object are projected onto the surface of a cylinder, by means of rays that all pass through a common point on the axis of the cylinder. Then the surface of the cylinder is unrolled flat to create the final image.
1 Conic curves in general, depending on orientation of straight lines in object
2 Parabolic curves only
3 Circular and elliptical curves only
4 Hyperbolic curves only
5 Trigonometric curves in general, depending on orientation of straight lines in object
6 Sinusoidal curves only (or Cosinusoidal if you prefer--they differ only by phase)
7 Cosecant curves only (or Secant if you prefer--they differ only by phase)
8 Not limited to conic or trigonometric curves
If either 2, 3, or 4 is true, do not choose 1. If either 6 or 7 is true, do not choose 5.
