  • Page 4: Introduction

    The DVC-4000 cameras are based on the Kodak KAI-4021 interline CCD, which provides 2048 x 2048 pixel resolution and 7.4 µm square pixels with high quantum efficiency and low noise. The DVC-4000 is offered in both standard and cooled configurations, with a choice of Gigabit Ethernet or CameraLink interface.

  • Page 5: Receiving And Unpacking

    Receiving and Unpacking Your DVC-4000 camera was thoroughly tested and carefully packed at the factory. Once the camera shipment is accepted for delivery, the carrier assumes full responsibility for its safe arrival. Should you receive your shipment with any damage—concealed or apparent—please contact the carrier at once. The carrier will instruct you on how to initiate a damage claim.

  • Page 7: Operating Speed

    The DVC-4000 has five basic operating modes described in detail below. Each mode can be operated at either 20 or 40 MHz and can support binning and region of interest. Cooled cameras utilize proprietary timing to completely remove “diode glow”...

  • Page 8: Continuous, Overlapped Exposure Mode With Electronic Shuttering

    However, developers have full control of these modes via the DVC camera API. Refer to Appendix A for exposure timing diagrams. 5.2.1. Continuous, overlapped exposure mode with electronic shuttering This mode operates the CCD in a “video” mode, in which the previous exposure is being read out while the current exposure is underway.

  • Page 9: Edge-Triggered Exposure (Single Frame Capture) Mode

    Bulb mode in the DVC-4000 is analogous in that the CCD exposes as long as the trigger signal is asserted (a low logic level on the external trigger or a low command on the CameraLink CC1 control line).

  • Page 10: Region Of Interest

    The KAI-4021 CCD is a high-performance image sensor with remarkably ideal behavior over a wide operating range. To be as versatile as possible, the DVC-4000 camera exploits as much of the CCD capability as possible and provides the user a great degree of control over the CCD functions. As a result, it is possible to observe some interesting, low-level CCD phenomena under certain extreme conditions.
  • Page 11 Smear is typically noticed during very short exposure times, when an extremely high light intensity is incident on the CCD. The result is regions of elevated signal level extending above and below very bright regions. Kodak interline CCDs exhibit very low smear levels, and smear should not be noticeable under normal operating conditions.

    To minimize the need to clean the optical surfaces, do not remove the protective lens mount cap shipped with the DVC-4000 camera until you are ready to mount the camera to the optical system.

  • Page 17: Warranty And After-Sale Service

    DVC such as lenses, optical and electro-optical assemblies, power supplies, cables, image processor boards and software are warranted by the original manufacturer. This warranty is in lieu of all other warranties expressed or implied. DVC shall not be liable for any collateral or consequential damages.

  • Page 18: Copyright Information

    In no event will DVC be liable for any direct, indirect, special, incidental or consequential damages, including lost profits, lost business, or lost data, resulting from the use or reliance upon the information, whether or not DVC has been advised of the possibility of such damages.

  • Page 19: Appendix A: Exposure Timing Diagrams

    Appendix A: Exposure Timing Diagrams Continuous, overlapped exposure mode with electronic shutter In the continuous, overlapped exposure mode, the camera remains in an idle state until the falling edge of the trigger. A first exposure is made, followed by the typical, interline CCD overlapped exposure/readout cycle.
  • Page 20 Continuous, overlapped, extended-exposure mode This mode is similar to the overlapped, electronic-shuttered exposure mode except that the electronic shutter is not enabled and the exposure times are greater than one readout cycle (frame time). As a result, readout frame rate will decrease as exposure time is increased, but the overlapping exposure and readout provide the maximum frame rate for a given exposure time.
  • Page 21 Continuous, non-overlapped exposure mode This mode is similar to the overlapped exposure mode except that the exposure and readout periods are separate and do not overlap. As a result, for a given exposure time, readout frame rates will be lower than that of overlapped exposure and will also decrease as exposure time is increased.
  • Page 22 Edge-triggered exposure (single frame capture) mode Edge-triggered exposure mode operates almost identically to the first frame of the non-overlapped continuous mode except that instead of continuing to run, the camera returns to the armed state, waiting for another trigger. Exposure is controlled by software. trigger ignored during exposure and readout trigger ignored during exposure and readout software...
  • Page 23 Bulb (pulse-width exposure) mode Bulb mode allows the camera exposure to be controlled by the external trigger signal. The leading edge of the trigger signal initiates the exposure, and the camera will continue to expose until the trailing edge of the trigger, as shown. The readout sequence begins immediately after the trigger signal trailing edge, and at the end of readout, the camera returns to the armed state, awaiting the next trigger.

    DIFF_RESET_OUT is labeled INPUT_1 on older DVC cameras and on the Mini-DIN- to-BNC cable accessory sold by DVC. Pin 3, TTL_RESET TTL_RESET is a TTL input used to trigger exposures. It functions identically to the CameraLink CC1 signal. TTL_RESET is also labeled VRST_INT on older DVC cameras and on the Mini-DIN-to-BNC cable accessory sold by DVC.
