Photographic camera
The aperture affects the image’s exposure by changing the diameter of the lens opening,
which controls the amount of light reaching the image sensor. Some digital compacts will
have a fixed aperture lens, but most of today’s compact cameras have at least a small
aperture range. This range will be expressed in f/stops.

of standard glass
xLCD Display - In some compact cameras this acts as the viewfinder. This
is a small screen (usually 1.8" diagonally or bigger) at the back of the camera
