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 camera
is very similar to the functioning of the
human eye
