The AGC is an electronic circuit of a camera. If the captured picture signal of the camera is weak, the AGC will
automatically increase the sensitivity of the camera. On the other hand, if the picture signal is strong, the AGC
will automatically lower the sensitivity, thus maintaining the level of signal output constant regardless of the
contrast difference of each shooting object.
Noise may be conspicuous when the illuminance of a monitored image drops. The DNR is a function that
discriminates and removes only the noise from the brightness and color signals of the image, thus reproducing a
beautiful high-quality image.
A color sync signal required for color reproduction. Usually, the monochrome signal is not superimposed with
any burst signal. If there is any image disorder when the image is switched from color to black and white with a
peripheral device such as a frame switcher connected, however, the burst signal will be superimposed on the
monochrome signal.
Contour compensation. The more the contour of a video image is emphasized, the higher a sense of resolution
of the video image will be.
