Basic Mechanism Digital Cameras

when you read the entry title above, do you know how the mechanism of action of recording a digital camera pictures?

Did you know that almost all digital cameras use the same mechanism although a different brand?

Have you crossed that the mechanism of the camera is recording images using the knowledge you have learned in the subject physics form 4?

Sure many are wondering is not it? Ok .. Positive attitude actually see how digitalcameras work ni.








1.)Order Element Lens Lens - Here is where you are so arranged that the diverging lensand                 focuses light from the object directly to your camera body.

2.)Reflector mirrors - mirrors are positioned 45 degrees to allow light reflected on towardsPENTAPRISM or mirrors PENTA.

3.)Focal Plane Shutter - usually found in film cameras. Consists of a thin cloth or metal that is not translucent and serves to allow light exposed to film.

4.)Focal Plane Shutter - usually found in film cameras. Consists of a thin cloth or metal thatis not translucent and serves to allow light exposed to film.

5.)Focus Screen - It is made of glass with a rough surface to allow camera users who want to see pictures taken with the VIEWFINDER. There are also some signs to indicatewhich part of the camera has to focus on an object, and it follows the model of their respective manufacturers.

6.)Condenser lens - Works to focus the light into a smaller line of light before enteringPENTAPRISM.

7.)PENTAPRISM / Penta Mirror - Work as a back-reflected light to reverse the reversedimage in the mirror (no.2) to enable the use of looking at the eyepiece as the actualsituation.




8.)Eyepice / VIEWFINDER - The eyes are placed to allow users to see the images the camera will be recorded in the camera.
