  • Page 15: Standard Composition

    The Camera Link interface brings RGB digital video output of 3 x 10 bit (HV-F31CL / HV-F22CL), or 3 x 8 bit (HV-F31CL-S1 / HV-F22CL-S1).
  • Page 16: Features

    LSI signal processing technology. • 6 vector masking Independent six colors masking is the Hitachi innovation for optimizing color balance. The saturation and the hue of 6 colors (Red, blue, green, cyan, magenta and yellow) are adjusted independently to deliver the best color in image capture, microscope and other applications.
  • Page 17: Notes To Users

    Confirm the power is off before connecting or disconnecting a signal cable. Grasp connectors by the body, not the attached wires. Lens The correct lens is important for deriving optimum performance from the camera. Consult a Hitachi Denshi dealer for a selection of fine lenses according to the application. Installation and storage sites The following types of environment can impair performance, lead to damage, pose safety hazards and shorten the useful life of the camera.

  • Page 19 2) Fixed pattern noise High ambient temperature can cause fixed pattern noise to appear throughout the scene. 3) Moire Interaction between patterns can produce an additional "phantom" pattern to appear. The CCD picture elements (pixels) are arranged in a pattern, which can interact with a pattern in the scene (e.g., a performer wearing a finely striped necktie) to result in a Moire pattern.
