Further information: Viewing instrumentThe first optical instruments were telescopes used for magnification of distant images, and microscopes used for magnifying very tiny images.

A camera could be considered a type of optical instrument, with the pinhole camera and camera obscura being very simple examples of such devices.

Famous quotes containing the word image:
“The paranoiac is the exact image of the ruler. The only difference is their position in the world.... One might even think the paranoiac the more impressive of the two because he is sufficient unto himself and cannot be shaken by failure.”
—Elias Canetti (b. 1905)
