Company Profile:
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.
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.
Industry:Consumer electronics
Available in cameras equipped with motorized focus, this feature provides automatic adjustment of the focus. AF operates by varying the focus to maximize the high frequency content of the central area of the picture by reference to high luminance and strong contrast elements. In some cameras, AF can be set to High or Low sensitivity modes. AF mode is not recommended for continuous 24-hour operation. See also One-push AF, Interval AF, Zoom triggered AF.
Industry:Consumer electronics
Interference phenomenon which occurs when a sampled signal contains frequencies that are higher than half the sampling frequency. A CCD samples the picture spatially. An optical low-pass filter is used to avoid aliasing, especially in color applications.
Industry:Consumer electronics
The ratio of width over height of an image, 4:3 for a standard TV image, 16:9 for wide screen.
Industry:Consumer electronics
Camera signal processing function which adjusts the enhancement of edges of objects in a picture.
Industry:Consumer electronics
IEEE 1394 data transmission mode without a guaranteed data delivery time. Used in IEEE 1394 cameras for control functions and reports.
Industry:Consumer electronics
In ATW mode, white balance is continuously being adjusted according to the color temperature of the scene illumination.
Industry:Consumer electronics
Special compensation option in AE (Auto Exposure) mode. When the background is too bright and/or when the subject is too dark, backlight compensation modifies the action of Auto Exposure to make the subject appear clearer.
