Hitachi HV-D25 operation manual Important safety notes, Operating considerations

∙Digital processing enables wide array of functions

Desired hue and tint can be adjusted with 6-vector independently variable masking. Even at wide dynamic range, auto-knee and dynamic chroma can provide superbly colored images.

The versatile detail compensating functions allow optimum contour compensation to match the scene.

∙Intelligent automatic level control (ALC)

Digital light metering of either the overall image or an iris gate with variable size and position, computer chip driven automatic gain control (AGC), lens iris and auto electronic shutter (AES) provide comprehensive control with respect to a wide variation in light. The ALC level setting is also variable.

∙Three application files

Different setting data according to the application and scene can be stored in 3 application files.

∙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.
