The image in a pin-hole camera is inverted and formed by the light from each point travelling in a straight line. This is because a pin-hole camera works by letting light through a tiny hole (pin-hole), which then creates an inverted image on the opposite side of the box or surface that is receiving the light. The smaller the pin-hole, the sharper the image will be, but it will also be dimmer. The image formed in a pin-hole camera is not refracted by a lens or created through dispersion, but rather through the straight-line propagation of light.
