The principle of an ordinary camera is: What is the difference between the refraction of light or the propagation of light along a straight line and a pinhole camera? Pinhole camera = pinhole imaging?

Ordinary cameras use the lens combination of lenses to project the scene onto the screen to become a real image, so it can be interpreted as the refraction of light; Pinhole camera uses the principle of pinhole imaging, but it is different from pinhole imaging; The pinhole imaging screen is used for real-time observation and has no exposure function, so when the object disappears, the image is gone. The pinhole camera has a negative that can accept exposure and can save the scene.

So, I wonder if I can be satisfied?
