2 1. General HV-27/HV-37 color camera is a separate type camera head utilizing three s in a compact and light weight and camera control unit (U) system. y utilizing 410,000 pixels (470,000 pixels PL) s in addition to single LSI chip digital circuit construction from processor to encoder, both high picture quality and high stability have been achieved. size is 1/2-inch for the HV-27 and 1/3-inch for the HV-37. 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 mount also allows use with a broad range of optical systems and opens up applications in a wide variety of fields, factory automation, image processing, microscope technology etc. 2. eatures 1) Single chip LSI camera signal processor 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. lso, the 12-bit / converter and 14-bit internal processor provide high signal to noise ratio and wide dynamic range. 2) mount The camera uses a mount lens, which is the de facto standard in the industry. Note : Some lenses cannot be used. heck before use. See 9 when using lens. 3) High resolution The 410,000 pixel (470,000 PL) s with high sensitivity microlenses are mated to prism optics using high precision matching technology. ccelerated digital luminance signal processing is used to deliver 800 TV lines (HV-27) / 750 TV lines (HV-37) horizontal resolution (luminance channel). 4) High S/N signal to noise ratio of 62 d (60d PL) is attained by the new digital noise reduction system. lear, low noise images are obtained even in the high gain mode. 5) High sensitivity The +24 d high gain mode and digital gain function provide sensitivity and low light performance 0.5lx, 1.6 (HV-27)/0.9lx, 2.2 (HV-37). When combined with the digital noise reduction system, pickup is enabled under adverse conditions that were beyond the reach of previous cameras.

3 6) igital processing enables quality enhancement functions xtensive experience in broadcast and industrial cameras is evidenced by the 6 vector independent variable masking, which is ideal for such applications as image processing and microscope technology where high color reproduction fidelity is essential. uto knee varies the high luminosity signal compression point according to the amount of incident light. ynamic chroma compensates for color loss in high luminosity signals. ynamic range is expanded to bring high reproduction quality even to outdoor scenes. Variable detail boost frequency is also provided. 7) uto shading compensation (S) olor shading incurred when using a 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. 8) drive functions Preset electronic shutter mode (10 steps) Lockscan mode reduces flicker in images with a different scanning frequency (e.g., a scene showing a computer display screen). The fixed frequency minimizes the appearance of a horizontal bar (not effective in all cases). uto electronic shutter (S) maintains a fixed video level. Long term integration mode accommodates field and frame integration (needs external video memory for a continuous picture). rame readout mode improves vertical resolution. (The sensitivity lower in S mode of frame integration.) ield on demand produces an image in response to an external trigger signal. (needs external video memory for a continuous picture). 9) Versatile pickup functions our scene files etail, masking, knee and other settings can be customized. Real time automatic white balance adjustment. The variable detector gate function can be utilized to avoid white balance disruption even if a light source having a different color temperature enters the scene. Intelligent L (auto level control) The digital light meter and PU processing provide continuous digital control of G, lens iris and auto electronic shutter over an extremely wide variation in lighting. The L level can be fine adjusted and the response selected for peak or average from the menu. (ombining with S is effective only with a manual override lens.) ull auto mode G and 1 step programmable gain switch WN SGN HK PP HV-27/HV-37 (3/17) Hitachi Kokusai lectric Inc

In multiple camera systems, each camera can be assigned an I number to enable controlling multiple cameras from a single computer. 11) Switchable video signal outputs The output can be selected for VS, Y/, RG, Y/R-Y/-Y according to the application. 3.

If too large, the lens and camera can be damaged Lens flange face T: HV-27: Less than 3.8 mm HV-37: Less than 4.3 mm 2) Selecting lens Overall camera lens make performance is largely affected by the lens. It is recommended to check the following points beforehand. Ghosting can occur by using a lens with a large image area (e.g. 2/3 or 1/2 inch for HV-37). Use a 1/2 inch lens for HV-27 and 1/3 inch lens for HV-37. Vertical color shading can occur if the lens has a short exit pupil length. If the lens is used at nearly fully open iris, resolution is sacrificed, while such problems as shading and flare can detract from the image quality.
