Working of CCD in Samsung Compact Camera.

 You aim the camera at the subject and adjust the optical zoom to get closer or farther away.

 ▼

 You press lightly on the shutter release.

 ▼

 The camera automatically focuses on the subject and takes a reading of the available light.

 ▼

 The camera sets the aperture and shutter speed for optimal exposure.

 ▼

 You press the shutter release all the way.

 ▼

 The camera resets the CCD and exposes it to the light, building up an electrical charge, until the shutter closes.

 ▼

 The ADC measures the charge and creates a digital signal that represents the values of the charge at each pixel.

 ▼

 A processor interpolates the data from the different pixels to create natural color. On many cameras, it is possible to see the output on the LCD at this stage.

 ▼

 A processor may perform a preset level of compression on the data.

 ▼

 The information is stored in some form of memory device (probably a Flash memory card).
