  • Page 2: Handling Precautions

    BEFORE USE ------ GENERAL SAFETY INSTRUCTIONS This instruction manual contains important information for the operator(user) and/or people around him/her to avoid personal injuries, or property damages against him/her or people around him/her by using this product correctly. Prior to use, read this operation manual carefully to fully understand its instructions for correct use.
  • Page 3 If any malfunctioning sign is observed, discontinue the use immediately. NOT try to use the camera when it is malfunctioning. (Ex. No images on the monitor) In the event of malfunction, turn the power switch of the system OFF immediately, and remove the camera cable from the camera connector. In such case, contact us or our dealer/distributor from which you purchased the camera for repair service.
  • Page 4 Avoid shoat-circuiting its signal output. Otherwise, the camera might be damaged. If too much amount of light, (= the incoming light amount of 100 times or greater in comparison with standard light) enters CCD image pickup plane, video output might not be obtained.

    IMPORTANT SAFETY INSTRUCTIONS (1) Use DC12V power. Avoid using any other unspecified power source. (2) This device is designed and guaranteed to work under the temperature range of 0 through 40 degree C. Avoid using the equipment beyond that limits. (3) Do NOT expose the camera’s image-pickup-plane to sunlight or other intense light directly.

  • Page 6: Product Description

    1. PRODUCT DESCRIPTION Model CS3720 is a separated-type (two-body) B/W CCD camera with all-pixel-data readout CCD. This model has twice greater driving frequency of CS3710 to achieve fast-speed data-processing. The model is suited for high-speed, high-resolution image processing use. 2. FEATURES (1) Double-speed scan This model reads out image-data twice as fast as conventional cameras do.

  • Page 9 (5)Partial-scan mode selection IMPORTANT Sometimes, white blooming is observed at the upper side of the screen when intensive light enters the image-pickup-area in a wide angle. This phenomenon is not attributable to malfunction of the camera. If the white blooming occurs, try and reduce the amount of incoming light.

  • Page 11 Under 1/60 non-interlace, the screen-center 226H is readout out of effective 492H lines (= excluding BLK lines). This works both under internal and external sync operation. 1/60s Non-interlace *1 High-speed Transfer *2 Normal-speed Transfer *3 High-speed Transfer *2 Normal-speed Transfer *1: Under ex-sync user-defined value.
  • Page 12 (5-2) PROGRAMMABLE: Readout portion programmable mode (Inner SW 1-2 OPT, SW 1-3 ON) In this mode, the readout portion is programmable via external pulse. High-speed transfer segment is set with partial pulse input. This works under external synchronization only. An example is shown below.

  • Page 15 (5-3) Reset: Sync-signal reset under partial-scan (Inner SW 1-4 ON) When the inner V-reset switch (SW 1-4) is set in ON position, VD signal will be reset immediately after image readout. This SW is enabled under 1/2 partial-scan mode only, and works under internal sync operation mode.
  • Page 16 (6)Multiple-shutter mode (Works under RTS mode) Under the random trigger shutter mode, consecutive trigger signals give cue for starting CCD exposure, arid image is output at user-defined timing. You can use this shutter mode under external synchronization operation (E.HD, E.VD) only. The video output timing is determined by E.VD.
