Camera Obscura: A darkened room or box with a small opening (pinhole) that allows light to enter, creating an inverted projection of the outside scene on a surface inside.

Pinhole optics refers to the principle of image formation through a small aperture, which allows light to enter and project an inverted image on the opposite side. This concept is fundamental to understanding how cameras work, particularly the camera obscura, as it demonstrates the basic mechanics of light travel and image projection without the need for complex lenses. The simplicity of pinhole optics makes it a crucial concept in the history of photography and optical devices.

Inversion: The phenomenon where an image is projected upside down and reversed left to right, a characteristic of both pinhole and lens-based optics.

The opening in a lens or pinhole through which light passes; it controls the amount of light that reaches the photographic medium.
