Hitachi HV-D30 3CCD Industrial Vision Camera

Oct. 5, 2010 - PRLog -- The multi-functional design, combined with the convenience of C-mount optics, is conducive to a wide range of industrial, medical, and other general purpose imaging applications. High Sensitivity and High Resolution are achieved through the use of three 1/3-inch CCD's, each with 410,000 picture elements (470,000 PAL). A 12-bit analogue to digital (A/D) converter and 14-bit accelerated DSP provides a horizontal resolution of 800TV lines. A high signal to noise ratio (S/N), 64 dB (62dB PAL), is obtained with the use of dynamic noise reduction (DNR). Clear high quality low noise images are now possible even in a high gain mode. A built-in flange back adjustment allows the Hitachi HV D30 optical focus to be optimized with the selected optical system. Four scene files are provided for the setup, storage and recall of all camera functions. The camera configuration can be easily changed through the selection of a scene file. A six-vector colour corrector allows independent adjustment of the hue and saturation of the primary and secondary colours so that optimum colour fidelity can be maintained. A versatile colour detail adjustment circuit enables the selection and independent adjustment of detail in two separate colours. This function can be used as a “flesh tone detail” circuit for smoothing human complexion, or for enhancing a colour contour for increased visibility.

Dynamic Chroma Compensation is provided to maintain proper colour saturation in scenes with high luminous levels. Dynamic range is expanded allowing high quality reproduction of outdoor and other difficult scenes. Intelligent Auto Level Control (ALC) can be selected to allow unattended operation over a wide range of light levels. Digital light metering, CPU controlled automatic gain control (AGC), lens iris, and an auto electronic shutter (AES) operate under continuous control to compensate for varying light levels. Auto Tracking White Balance (ATW) can also be selected to maintain proper colour temperature with changing light levels. Note: AES functions continuously only with a manual override lens. Flare Compensation can be adjusted to compensate for colour changes in dark areas, improving colour fidelity, when a zoom lens is used on the camera. Picture polarity can be selected as normal (positive) or negative, to suit the imaging requirements.  A full complement of video outputs is provided on the camera. Outputs include composite, Y/C, RGB, or Y/ R-Y/ B-Y. Simultaneous output of composite, Y/C and an additional component signal is possible, utilizing two separate output connectors.  The camera can be synchronized with external devices using the genlock input or by use of external HD and VD signals. Composite sync, HD and VD signals can be output for use with other equipment. An External Trigger Signal can be used to provide the capture of an image. Several trigger modes are available to suit the intended application. A long-term integration mode of up to 8 seconds can be used to capture images at extremely low light levels. An RS-232C port is provided for bi-directional communications with an external device, allowing complete control, setup and operation of all camera functions.


This camera, combining as it does superb colour reproduction with a wide range of features, is ideal for a vast range of applications from industrial microscopy to medical vision, print proofing to fruit and vegetable quality monitoring, etc. truly a versatile solution where accuracy is an essential
