Hitachi HV-D30 - Manual (Page 15)

Clear low noise images are obtained even in high gain mode.

Auto shading compensation (ASC)
x
Color shading incurred when using a C mount lens is automatically compensated
(attenuated).
Two modes of shading are provided and can be selected according to the cameras
application, a vertical color shading mode or a two-dimensional luminance-shading mode.
x Bi-directional data communication
The camera can be connected to a personal computer via RS-232C for two-way data
communications to provide finely detailed camera control. An identification (ID) code
can be assigned to each camera in a system and allow remotely controlling multiple
cameras from a single computer.
