F


Face Detection
Recognizes faces in the picture, automatically adjusting focus, exposure, white balance and flash setting for natural portraits. Up to eight faces can be recognised in a scene. Priority can be set to children or adults.
Fader
Feature used for a professional transition between scenes incorporating the ability to select up to seven modes.
Fairplay DRM
Fairplay DRM (Digital Rights Management) is an access control technology that limits the copying of iTunes® to another format. Files controlled by this include AAC, M4V and M4P. A file encoded with Fairplay DRM is impossible to play on devices other that an Apple iPod.
Fasttext (FLOF = Full Level Of Features)
Colour-coded buttons on the remote control give direct access to certain pages without entering the page number.
FD Trinitron® Super Fine Pitch
The Super Fine Pitch Tube dramatically improves picture resolution. The centre-spacing tube slits have been reduced to 0.47 mm increasing the horizontal resolution by 60% and improving fine picture detail. A new CRT drive circuit improves focus by up to 25%.
FD Trinitron® WEGA®
The Sony FD Trinitron® WEGA® is the first picture tube with a screen that is absolutely flat, both vertically and horizontally. It delivers impressive flicker-free pictures with practically no reflection.
Feather Touch Mechanism
Is a low friction key for quick operation.
Field
Video is created using lots of still images, which when shown quickly enough create the illusion of movement. Each of these still images is known as a frame. With an interlaced system, each frame is divided into two further separate images – one containing odd horizontal lines and the other containing even horizontal lines. These new images are known as fields. In Standard Definition PAL, there are 25 frames every second. As PAL is an interlaced standard, each frame is split up into fields. This gives PAL 50 fields per second (more commonly known as 50Hz).Unlike interlaced formats, 720p and 1080p HD formats use progressive scan which does not divide frames into fields. Progressive displays show the whole frame at once for an all round clearer image.
Finalise
To allow a CD-R to be interpreted (read) by a CD-ROM drive, the disc has to be "finalised" after a single or multi-session. This process involves writing the table of contents (TOC) of the CD.
Fine Pitch
Fine-pitch picture tubes have more densely packed pixels. The resulting colour picture provides enhanced resolution, greater detail and sharper contours.
Fixed Pickup Mechanism
During playback, the discmotor is moved together with the CD and the laser is fixed.
FL Display
High definition fluorescent display
Flash Memory
A memory chip that is used to store data. Products with Flash Memory can therefore be small and compact in design. Another advantage of Flash memory products is stability – they never skip with sudden movement because there are no moving parts. However, Flash memory products have a smaller storage capacity than hard disk products.
Flash Mode
A number of flash modes are available on Sony digital still cameras: Auto -- automatically triggers under low light conditions. Forced Flash -- the flash is always activated. Anti red-eye reduction -- uses a pre-flash flicker to close the subject's iris and minimise red-eye effects. No flash -- does not activate.
Flash White Balance
Flash White Balance is a digital photography feature that helps retain colour tones under difficult shooting conditions. In conditions where there are many reflective surfaces, the camera might detect all light sources around the subject, creating a colour distortion. This is avoided by automatically adjusting the white balance in the shot to restore colours to their true natural condition when using the flash.
Flat-panel TV
Any ultra-thin, relatively lightweight TV — especially those which can be wall-mounted. Current flat-panel TVs use either plasma or LCD technology.
Flying Erase Head
Conventional video recorders have an erase head that is some distance from the record/replay head, making video editing impossible. A rotating erase head is one that is positioned on the video head disc and erases the tape exactly at the recording position. Flying erase heads are standard in Video8, Video Hi8 and high-quality VHS recorders. As a result, recorders provided with this feature are ideally suited for video editing and give a perfect insert cut.
FMP
Flash memory player. A digital music player using embedded flash memory chip.
Focal Length
The focal length of a lens is the distance along the optical axis from the lens' second principal point to the CCD plane when the lens is focused at infinity.
Focal Length (Compare to 35 mm Photo)
Digital cameras and 35 mm cameras have lenses with different focal lengths. The focal length is the distance between the lens and the surface of the sensor. A typical digital sensor is approximately one-sixth of the linear dimensions of the 35 mm film. In order to project the image onto the smaller digital sensor, it is necessary to shorten the focal length by the same proportion. For example, using a 1/4 inch CCD, the focal length must be multiplied by 9.5 for correct comparison to 35 mm film.
Freeview
The Freeview system in the UK is the name given to digital terrestrial services. A viewer is able to receive a selection of digital channels for free through a set-top box or via a Freeview-enabled TV set. See www.freeview.co.uk for more information.
Frequency Synthesiser
This allows the receiver to be programmed by entering the channel directly.
Front AV/Front YC (S-Video)
These are ports on the front panel that facilitate the selection and control of external video sources.
Front Portable Audio Input
For quick and easy connection of your personal audio player to your hifi/home cinema system.
Full Feedforward Digitalfilter (FF Filter)
An IC Chip that processes digital audio signals for the D/A converter. With the help of a mathematical operation during the oversampling process, the quantisation noise is minimised and sound quality is optimised.
Full HD 1080
BRAVIA sets with Full HD 1080 reproduce the maximum HD1080 picture exactly as it was transmitted. This is instead of creating scaled images which have been digitally reduced to fit lower-resolution TVs. An unprecedented degree of detail and clarity is brought to standard television broadcasts, with Full HD 1080 boosting the image resolution by up four times.
Full Logic Operation
In early cassette drives, the operating keys were used to physically move part of the cassette mechanism. Using full logic control, the keys control electronic functions giving a smoother touch-sensitive operation.
Full Range Auto Focus
Multi-point auto focus guarantees razor-sharp images over the full zoom range from wide angle to macro.
Full Spectrum Sound
A loudspeaker design that incorporates the tweeter diaphragm mounted on magnetic bearings and a downstream acoustic lens.
