HITACHI HV-D27E Product Description:

The HV-D27 is a separate head 3CCD type colour camera with a compact and lightweight camera control unit (CCU). The HV-D27 features 1/2" format CCD's. Each CCD contains 470,000 pixels (picture elements). The C mount lens fitting provides convenient physical compatibility with a broad selection of readily available and specialised optical systems. For improved performance and reliability, the CCU circuitry from the processor to the encoder is contained in a single VLSI DSP semiconductor chip. The small and lightweight head makes this camera an excellent choice for medical systems, industrial automation, image processing, microscope equipment and a nearly unlimited range of other applications.
