Detailed Solution

The above statement is false.
A pinhole camera can form an image larger than the object since the image does not depend on the shape of the pinhole. The pinhole camera forms a real, upside-down image and the size of the image of the pinhole camera depends on the distance between the screen and pinhole camera. Pinhole cameras work on the principle of rectilinear propagation of light. Light falls from the object through the pinhole and forms a tiny image on the screen if the pinhole and the screen are close. If the distance between the screen and the pinhole increases. It forms an even bigger image than the object.
The correct statement would be that changing the pinhole's shape will not affect the image.
