The Pinhole Camera Model demonstrates the operation of a pinhole camera. Light rays leaving the top and bottom on an object of height h, pass through a pinhole, and strike a flat screen. These rays travel in straight lines in accord with the principles of geometric optics. Drag the object and observe the image on the camera screen. Simple geometry shows that the image is inverted and that the ratio of the image to object size (the magnification) is the same as the ratio of the image to object distance.
