Clear Colour NR
Clear Colour Noise Reduction is a feature used in digital photography. It analyses the light and colour frequency of the image and smoothes out any distortion caused by long exposure times, creating a natural tone reproduction. It is particularly useful when photographing landscapes, as large areas of the same colour -- such as clear blue skies, dark blue seas and green forests -- benefit from richer colour definition and are reproduced more realistically.
Clear Luminance NR
Clear Luminance Noise Reduction is a digital photography feature providing crisper, cleaner images with increased contrast. It uses a filter to improve images taken in bright light. This improves detail in areas where light levels are high, avoiding noise that could be confused with details in the picture. Unlike conventional noise reduction systems, it suppresses image noise without affecting the image detail.
Clear Photo LCD Plus
Clear Photo LCD Plus is an improved visibility LCD screen with higher screen resolution and an increased colour gamut with higher contrast. This enables better film composition and focussing, in dark or bright environments and a sharper image during playback

Clip Motion
Clip Motion allows you to create an animated GIF sequence from your digital camera. Using 10 shots of your subject taken in Clip Motion mode, the camera will create a 256-colour animation at a resolution of 160 x 120. Animated GIFs are particularly suited to e-mail, web pages and a host of presentation uses.
Closed headphone
Closed headphones are ones where the entire ear is covered by the headphones and consequently the acoustic properties of the headphones can be very closely controlled. The result is almost complete shielding of external noises and a very high playback quality, particularly within the bass area. Closed headphones are ideal for hi-fi use.
Club VAIO
Supplies all registered VAIO users with technical and background information as well as software updates. Also includes a special ordering service for accessories with direct dispatch within 24 hours and the provision of a personal homepage (www.club-vaio.com).
CMOS
(Complimentary Metal-Oxide Semiconductor) Camcorder and digital camera sensor technology which, like a CCD, converts light into electrical signals. The benefits of CMOS are less smear, wider dynamic range for superior contrast and lower power consumption for efficient battery operation.
Coaxial cable
A cable in which one conductor is accurately centered inside another, with both conductors carrying signal ± primarily for the transmission of high frequency, such as digital signals or television.
Codec
(Coder – Decoder) This is the term given to audio compression systems. Codec systems work out the sounds we can and cannot hear, and then save only the information that is audible. This can be done in a number of ways. One way is not recording sounds that fall outside our range of hearing. Another is to remove any sounds that are masked by other, louder sounds. Alternatively, Codecs can concentrate solely on frequencies that our ears are most sensitive to. This software can reduce or compress data so that it takes up less storage space, and then restore it for playback. Examples of Codec systems are MP3, WMA and ATRAC3.
Colour Depth
Represents the number of colours that can be recorded or displayed. The more bits, the more colours that can be recorded. To represent 16.7 million colours you need a colour depth of 24 bits (8 bits per colour: red, green and blue).
Component Video Out
Outputs the video signals, as they are stored on the disc, for best-possible picture quality on professional projectors or monitors.
Composite Video
The composite video signal is one where the luminance and chrominance are mixed together.

Continuous AF
The camera continually adjusts auto focus during ‘burst’ shooting to ensure moving subjects stay in sharp focus.
Continuous/Multi-Point/Centre-Weighted Auto Focus
These are different methods of Auto Focus for digital photography. Continuous AF provides correct focus using the shutter button. Normally, pushing the shutter button half-way down will ‘lock’ the image focus. In Continuous AF mode, the camera continues focusing until the correct focus is achieved. Multi-Point AF does not use focus lock, giving more creative freedom while ensuring that your subject is always in perfect focus, even when not in the centre of the scene. Centre-Weighted AF uses the centre of the image for focusing.
Contrast
To adjust viewing on your monitor
Contrast Ratio
The ratio between the darkest and lightest spot projected onto a screen by a projector or visible on a screen.
Control A1
Control A1 is a multifunction data bus system used for communication between Sony audio components. Functions can be automated and text information transferred between, for example, a CD player and amplifier.
