Color temperature
The temperature in Kelvins (K) to represent the color of a light source, determined by heating a perfectly black body until its color matches that of the light source. Color temperature is higher when the color is bluish and lower when reddish.
Condensation
Moisture condensation on the VTR tape transport mechanism. Condensation on the head drum causes tape to stick to the drum, resulting in damage to tape and a malfunction of the VTR.
CRT
CTL
Control signal in the form of regular pulses recorded along a longitudinal track on the video tape. By counting these pulses, it is possible to
A determine the number of frames, and hence the tape running time. Used mainly to adjust the tracking position of video heads, and to achieve time code continuity in continuous recording.
DCC
Dynamic Contrast Control. A video camera containing a DCC circuit can handle a wide dynamic range of luminance.
Diopter
A measure of lens power ; its unit is the reciprocal of 1 m (3.28 ft). A diopter lens is a simple supplementary lens placed over the main camera lens to alter its effective focal length.
