Hitachi HV-D37A, HV-D27A Features, C moot, High quality picture, Auto shading compensation ASC

Features

Single chip LSI camera signal processor Hitachi's leading edge processing technology (0.18 um, internal core 1.8V drive, and 3 million gates) is contained on a single newly developed ultra LSI chip. The system is compact and consumes very little power. Also, the 12-bit A/D converter and 14-bit internal processor provide high signal to noise ratio and wide dynamic range.

C moot

The camera uses a C mount lens, which is the de facto standard in the industry

Note : Some lenses cannot be used. Check before use. See page 7 when using lens.

High quality picture

Three 410,000 pixel (470,000 PAL) CCDs with high sensitivity microlenses are mated to prism optics using high precision matching technology. Accelerated digital luminance signal processing is used to deliver a horizontal resolution of 800 TV lines with HV-D27A and 750 TV lines with HV-D37A (luminance channel).

A new digital noise reduction system provides 62

2

dB (60dB PAL) with HV-D27A and 60dB (58dB PAL) with HV-D37A signal to noise ratio. Clear low noise images are obtained even in high gain mode.

Auto shading compensation (ASC)

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.

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.
