In a color camera, white balance is the process of adjusting the values of its color differences signals so that a white object in a scene illuminated by a particular source of illumination is displayed as a white or grey (i.e. no chrominance). The normal color reference illuminant has a color temperature of 3200 K, equivalent to a halogen lamp. The human eye is a subjective device, constantly readjusting its color balance according to the lighting context (our eye knows what must be seen as white). Unlike the human eye, a camera is an absolute measurement device, and its color balance has to be adjusted to suit the color temperature of the light illuminating the scene, for example sunlight is different from 3200 K. Several adjustment modes are available, fixed values (pre-adjusted), One-push, automatic tracking. See also One-push WB and ATW.

Separate signals for the Luminance and Chrominance parts of the video signal. Allows higher picture resolution and suppresses cross color effects. Connector is the 4-pin mini-DIN.

The camera is normally in fixed focus mode, but AF (Auto Focus) is temporarily switched on each time the zoom ratio of the camera lens is changed.

Three signals, luminance (Y) and two color difference signals R-Y (red minus luminance) and B-Y (blue minus luminance) which together carry the brightness and color information of color images . Color difference signals have no light intensity information, and cannot be displayed separately from Y. Compared to RGB signals, they can travel over longer cables lengths without significant resolution loss, and allows different spatial resolutions for luminance and color. Typically used for high-end visual applications. Also known as component signals. See also U and V signals.

Technique allowing pictures to be shot without visible light. The camera is switched to its infrared sensitivity mode and infrared lighting (built-in to Sony IR sensitive cameras) is used to illuminate the scene. As the picture is only infrared, no significant color information is displayed. The picture looks slightly greenish, like an image intensifier picture. NOTE: In 0 LuxShot mode, the iris remains in a fully open position, and the high-speed shutter feature does not function.

Indicates the sampling applied to the Y/R-Y/B-Y components of an analog video signal when it is converted into a digital signal. The three numbers indicate the ratio of the sampling rates applied to the individual signals. 4:4:4 indicates that the same sampling rate has been applied to all three signals, 4:2:2 means that the sampling rate of the R-Y and B-Y color difference signals is half that of the luminance signal Y, while 4:1:1 indicates that the sampling rate is one quarter that of the Y signal.
Industry:Consumer electronics
Combined use of AGC and iris motor control allows shooting in a broad range of lighting conditions. AGC amplifies the video signal in low light conditions, iris reduces it in high light conditions. Motor iris control can be replaced by the CCD IRIS control.
Industry:Consumer electronics
Circuitry that automatically adjusts the electronic amplification of the video signal to compensate for varying levels of scene illumination.
