The human eye and a camera lens have a few things in common most notably that they both use a converging lens to receive and project images. But human eyes and camera lenses have many things that set them apart from each other.

“Retina Provides Color

• the image an eye perceives is projected from the cornea to the retina, which absorbs the image and projects it to the brain. A camera projects an image on to film where it is captured and saved as a black and white image. The retina contains millions of cones that provide the image with color.

Stereoscopic View

• the biggest difference between eyes and a camera lens is that two eyes give us stereoscopic vision. This allows our eyes to project a more detailed image to the brain than a

That's a level of data compression/packing (relatively lossless) orders of magnitude greater than we can achieve with current technologies.

The camera and the eye have much more in common than just conceptual philosophy--the eye captures images as does the camera. The anatomy of the camera is more similar to that of a biological eyeball than many would imagine. Similar functions in common give the camera the appearance of a robotic eye. However, though there are many similarities between the two, they are by no means identical.

Comparison of the human eye and a camera

Cornea and Lens

• The cornea is the "cap" of the eye; it is transparent (like clear jelly) and sits to the front of the eye and has a spherical curvature. The lens of a camera is also transparent (glass) and sits at the front of the body. Like the cornea, the lens also maintains a spherical curvature. The purpose of the corneal and lens curvature is to allow for the eye and camera to view, though not in focus, a limited area to both the right and the left. That is, without the curve, the eye and camera would see only what is directly in front of it.

Iris and Aperture

• The aperture is to the camera as the iris is to the eye. The aperture size refers to
