HITACHI HV-D20P
HITACHI HV-D20P Product Description:
The HV-D20 is a three CCD color camera combining high picture quality and high stability with the convenience of C mount optics. CCD size is 1/2-inch and each is comprised of 470,000 picture elements. The circuits from processor to encoder are digitized and contained on a single LSI chip. Hitachi's extensive experience in broadcast and industrial color cameras has lead to an exclusive 14-bit digital processing technology that provides a host of important functions in a newly developed LSI device. The high quality signal processing and image compensating functions were unattainable in earlier analog cameras. The versatile C mount also allows use with a broad range of optical systems and opens up applications in a wide variety of fields.FEATURES:
- C-mount: The camera uses a C mount lens, which is the de facto standard in the industry.
- One chip LSI: Hitachi’s leading edge processing technology (0.18 µm, 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.
- High picture quality: High resolution and sensitivity are achieved through the use of advanced CCD technology and three 1/2 inch 470,000-pixel CCD’s. Together with the 12-bit A/D converter and 14-bit internal processor, a horizontal resolution of 800 TV lines and 62dB signal to noise (S/N) are obtained with the use of the new digital noise reduction system (DNR). Clear low noise images area obtained even in high gain mode.
- 6 color independent masking: The user can adjust hue and saturation of the three primary color (R, G, B) and complementary color (Mg, Ye, Cy) independently.
- Auto Shading Compensation (ASC): The ASC function can automatically compensate for color shading errors caused by interaction between the lens and prism assembly in C-Mount optical systems. Three modes of shading are provided and can be selected according to the cameras application, a color shading mode, a two-dimensional luminance-shading mode, or a fl at shading mode.
- Intelligent ALC (Auto Level Control): Unattended operation under a wide range of illumination levels is possible with the selection of the auto mode from the main menu. The built-in microprocessor controls the gain (AGC) function, the auto electronic shutter (AES), and auto iris function so the proper video level is maintained over a wide range of light levels.
- RS-232C Interface: Control of camera functions and storage of setup data can be performed with the use of a personal computer through the use of the RS-232C interface.
