SIMILARITIES BETWEEN CAMERA & HUMAN EYE:

      There are many similarities between the human eye and a camera, including:

• a diaphragm to control the amount of light that gets through to the lens. This is the shutter in a camera, and the pupil, at the center of the iris, in the human eye. 
• a lens to focus the light and create an image. The image is real and inverted. 
• a method of sensing the image. In a camera, film is used to record the image; in the eye, the image is focused on the retina, and a system of rods and cones in the front end of an image-processing system that converts the image to electrical impulses and sends the information along the optic nerve to the brain.
• DISSIMILARITIES BETWEEN CAMERA & A HUMAN EYE

  1.Eye is a live organ for sight whereas a camera is an equipment to capture images.
  2. Eye uses live cells to detect light while the camera uses a diaphragm to detect light and capture images.
  3. Stereoscopic vision of eyes allows 3 dimensional images while camera captures only 2 dimensional images.
  4. The pupil adjusts the size while focusing while in a camera lens moves to change focus.
  5. Eyes have blind spots while cameras do no not.
