The simplified version of how the camera works is that it uses lenses to focus light on the photodetector. Most compact digital cameras use charge-coupled (CCD) as a photosensor. When light hits the sensor, it will save the image and transfer it electronically to the organization. After that, it will convert the image into binary digital data and stored in memory.

To get a perfect picture, the amount of light reaching the photosensor must be carefully controlled. To do this, you need to control the shutter speed and aperture size. To make things easier for you, the compact digital camera manufacturers put speed electronic shutter and define the size of opening on automation.
