A cam­era is an opti­cal instru­ment that records images that can be stored direct­ly, trans­mit­ted to anoth­er loca­tion, or both. These images may be still pho­tographs or mov­ing images such as videos or movies. The term cam­era comes from the word cam­era obscu­ra (Latin for “dark cham­ber”), an ear­ly mech­a­nism for pro­ject­ing images. The mod­ern cam­era evolved from the cam­era obscu­ra. The func­tion­ing of the cam­era is very sim­i­lar to the func­tion­ing of the human eye.
