• Working of Digital Camera:

• Based on CCD mechanism.

• CCD consists of cells arranged in fixed array on surface/behind the lens.

• CCD cells get charged by intensity of light.

• This charge generates voltage which is then fed to A-D converter.

• It converts charge voltage to digital value.

• This values are stored in camera memory

• This data can be moved from camera memory to computer memory, other memory devices and so on.
