This function is designed to capture fast moving, full frame images by firing a strobe light in a dark lighting condition. The camera synchronizes the timing of the external trigger and can output a full frame image. Using an external frame memory synchronized with the input of external trigger signal, the Write Enable (WEN) pulse is output. The use of the WEN pulse allows for easy capture of full frame still images. This function requires a frame grabber board.

When synchronized, the horizontal and vertical timing of a camera output are locked to an external signal coming, for example, from another camera. Picture outputs from both sources are then precisely synchronized and can be mixed. When mixing color signals, the subcarriers of the two signals also have to be in synchronism.
Industry:Consumer electronics
The 4.43 MHz (PAL) or 3.59 MHz (NTSC) signal that is used as a carrier for the color information. This subcarrier is modulated in amplitude by the color saturation and in phase by the color hue. A sample of the unmodulated subcarrier is placed before the start of each horizontal line, and is called the Color Burst.
Industry:Consumer electronics
The names given to the two video color difference signals (R-Y and B-Y) in their coded form in the PAL or NTSC color systems. See also Y/R-Y/B-Y.
Industry:Consumer electronics
Type of camera mount in which there is 6.7 mm clearance between the lens rear mounting surface and the camera’s CCD.
Industry:Consumer electronics
The composite video signal, including color information.
Industry:Consumer electronics
Signal used to synchronize the field rate of a camera to an external source. Mostly used in B/W together with HD (Horizontal Drive).
Industry:Consumer electronics
Number of equally spaced horizontal black-to-white or white-to-black transitions that a camera is able to reproduce. Indicates the amount of vertical details that can be perceived. Vertical resolution is limited by the number of scanning lines that are fixed by the TV standard.
Industry:Consumer electronics
RS-232C serial control protocol intended to interface up to seven items of video equipment on one computer link.
