Any film camera with a light meter, and every digital camera, has a sensor that will do that.
CMOS is a type of sensor built in to an SLR camera.. Another sensor you may come across is a CCD sensor witch tend to be smaller.
It is important that the sensor receives the correct amount of light. To restrict the amount of light would produce poor results.
No cant :0Update: Digital camera's can be damaged by pointing directly at the sun. The CCD or CMOS sensor is suseptible to burn in the same as a Plasma TV and this will render the camera useless...it says so in the manual that came with my digital SLR camera.(Canon). Don't risk it.
The functional opening is the aperture, the opening that controls the amount of light that hits the photosensitive surface. You may have a camera with interchangeable lenses that screw into and out of the camera's body. The opening into which the lens is screwed is not the aperture.
Because its diameter can be changed to alter the light level on the sensor behind it. In a camera this is done by altering the f/number. In the eye it occurs via an automatic physiological response.
Digital camera
Centers and refocuses light onto the camera's sensor.

The Sensor
No it appears to have a camera but it is actually a light sensor
It focuses the light entering the camera onto the sensor.
Its not a camera its a sensor
sensor is basically a device which detects and converts your signal of interest into a measurable or observable quantity (mostly an electrical signal). Say for example, a pressure sensor detects pressure and converts it into an electrical output which can be further processed for actuation or to be displayed.
No, it does not have a front camera. What you see is a sensor.
CCD Sensor (in a digital camera) = Retina
the main function of a camera is to take pictures
Yes it is
