The following are some common digital camere parts.
AD converter
The AD is the short form for Anolog to Digital. This digital camera part amplifies and processes the anolog signal from the CCD. The ADC value is the amount of light which was captured by a single pixel on the sensor (CCD). The 8-bit ADC ( about 256 distinct values for the brightness of a pixel) is normally used in cheaper digital cameras like the consumer digital cameras. On the other hand, more expensive digital cameras like prosumer and Digital SLR use 10 or 12-bit ADC (about 1024 or 4096 distinct values) allows for a finer graduation of the differences between one brightness and the next.
AF Servo
This measures how good the digital camera continuously focus on a moving subject. This feature mostly found on more expensive cameras.
Buffer
The main function of this digital camera part is to shorten the time between shots and gives the digital camera the ability to shoot burst (continuos) shots. Basically it is the RAM storage which temporarily stores images before they're written out to the storage card.
Colour Filter Array
Photodiodes used to measure the amount of light for each pixel on a CCD can't themselves tell the difference between different wavelengths of light so a digital camera part called CFA (colour Filter Array) is placed over the monochrome sensor pixels to produce a colour image. The GRGB Bayer Pattern is the most common CFA used.
DPOF
DPOF (Digital Print Order Format) is commands in a digital cameras storage card to define what captured images, how many copies of each imageare and etc. to be printed on compatible print devices.
EXIF
EXIF (Exchangeable Image File) is a file format published by JEIDA (Japan Electronic Industry Development Association) in an attempt to standardized file format used by current digital cameras.
LCD
The LCD of a digital camera is the screen used to review, preview and even act as a large size viewfinder. This is one of the most important digital camera part.
Storage Card
Another important digital camera part is the storage card. This is the film of a digital camera and most high-end digital cameras have removable storage device but a few low-end digital cameras don't have removable storage cards but instead have a built-in flash RAM unit.
PCMCIA PC Card-These cards are only found on high end processional digital SLR's, because of their large size they're not compact enough to be used in a "compact" digital camera.
Compact Flash Type I-Probably the most common format used today, found in both digital cameras and other devices (PDA's, network applications etc.).
Compact Flash Type II-Same as Type I only thicker.mBR>
SmartMedia-Thinner than Compact Flash and without the controller chips found in a Compact Flash card.
Sony MemoryStick-Chewing gum sized storage that only found on Sony digital cameras.
Viewfinder
The optical "window" you look through to compose the scene. There are three different types of viewfinder and the most common is the Optical Viewfinder. The remaining two are Electronic Viewfinder (LCD Viewfinder) and TTL (through-the-lens) Optical Viewfinder.
AF Assist Lamp
This is the typical digital camera part mostly found on consumer digital cameras. The lamp (normally located beside the lens barrel) which is used to illuminate the focus subject in low light. These lamps usually only work over a relatively short range, up to about 4 meters.
