2.5 OPTIONAL ITEMS The following items are optional items and may be ordered from authorized dealers of DVC. They are not typically supplied with each Camera. 1. Lenses and/or other optical elements 2. Third party Image Analysis software, e.g. ImagePro, Adobe Photoshop®, QED Imaging, Improvision, etc.
3.2.2 What causes the CCD imager to get dirty? Dust and dirt are the culprits. At DVC, professional cameras are manufactured under strict conditions and assembled in a dust-free room. Before shipping, each camera is tested and checked to assure that it meets stringent specifications for cleanliness and quality. Although we take extreme care to produce a dust-free camera, changing lenses, or static can cause debris to appear on the imager.

5.2.1.2 Charge Transfer During the Vertical blanking interval, the charge that was integrated in each active charge site during the previous exposure (normally 1/10 sec, or one frame) is shifted to an adjacent opaque storage charge site. In the figure below, active charge sites are designated by the letter “I” for integration and the opaque storage charge sites are designated by the letter “S”...
5.2.4 Voltage Regulation Input voltages (+15V, -15V and +5V) are converted into several positive and negative voltages required by the CCD and in the video processing circuits. 5.2.5 Timing This logic block on the CCD and Video board performs the following functions: •...
6 INSTALLATION Refer to Installation and Operation Manual 7 MODES OF OPERATION 7.1 NORMAL MODE In each mode description, the serial mode commands (CameraLink and LVDS versions only) are shown. Please refer to the serial mode commands details in Section 9.4. NRR: Normal mode with reset NOR: Normal without reset In the normal mode of operation, the following signals are used to synchronize a digital frame...
Every horizontal line during the next frame, one line of the charge matrix in the opaque storage sites is shifted vertically into a horizontal shift register. The horizontal shift register is clocked out, one pixel at a time, on to a charge detection node that converts it to a voltage, which can be sampled and digitized.
purpose, a STROBE output pulse is generated within the camera. The STROBE output pulse allows an external strobe light to be turned on during the exposure period. Since the duration of the exposure is a user-programmable setting, the start-time (relative to the vertical timing of the camera) and the duration of the STROBE output pulse also vary, depending upon the shutter setting.
Page 25
NOTE: Frame grabbers have the ability to control the differential input (CC1+, CC1-) or (INPUT1+, INPUT1-) of the camera. This is facilitated by connecting them via two wires within the camera-framegrabber interface cable to differential frame grabber outputs that are driven by a General Purpose register bit that is to be controlled by host software.
7.2.4 Reset Modes In the HDO and HDL shutter modes, an asynchronous falling edge on the VRST_INT (TTL) or CC1/INPUT1 (differential) input of the camera is used to synchronize the exposure period of the camera to the outside world (the rising edge is not significant, however, the LOW duration should last at least 1µsec).
7.2.4.2 High speed shutter with discharge (HDL) If an asynchronous reset occurs while the camera is in this mode, the residual charge in the storage area from a previous exposure is flushed out (discharged) by a sequence of vertical channel transfer pulses.
When the low-speed shutter mode (or N Frame Integration mode) is selected, the duration of exposure is set as an integral number of frames. For the DVC-1412 camera, the duration of exposure can be set from 1-to-1024 frames, in 1-frame increments. NOTE: since one frame is 1/10sec or 100msec, the range of control is from 1/10sec to 102 sec.
invoked with an increment of 120 frames = 12 sec. The transition between NFR mode and ULT mode may be transparent to the user; the only real difference between the ULT and NFR mode from the user’s perspective is the “granuality” of control. 7.5 PULSE DRIVEN EXPOSURE PDX: Pulse driven exposure (external) PDI: Pulse driven exposure (internal, one-shot)
duration and the instant of exposure. For example, application software can be written to directly drive the camera between long and short exposures without any latency; some application developers choose to use the PDX mode as the sole camera mode, since this can control long and short exposure easily by controlling a single signal.
7.6.1 Binning and Shutter: The following table is provided as a guide for calculating the shutter mode exposure values that apply in the different binning modes. The shutter setting for binning modes needs to be shifted with an offset, in order to get the desired amount of exposure: mode no exposure...
In many applications, users wish to designate a particular Region of Interest (ROI) within the entire image. The ROI feature of the DVC-1412 allows the definition of a band of pixel-rows that are selected for readout. The CCD is then fast-scanned through the un-selected areas, allowing for a faster overall frame rate of only the selected area.
trimmed in display with software unwanted - fast scan wanted wanted [normal scan] [normal scan] unwanted - fast scan 7.7.2 Advantages ROI allows faster frame rate without compromising spatial resolution. The benefit of ROI is that fewer lines are scanned instead of scanning all lines of the CCD. Thus, a higher number of frames per second are achieved.
In the present implementation, ROI and BIN are mutually exclusive commands. This will be changed in later versions. 7.8 SLOW SCAN Slow scan: The read noise of a CCD is significantly affected by the scanning rate. Some users wish to improve the read noise by slow-scanning the CCD. This is provided in the camera by means of a clock multiplexer scheme;...
7.9 INTENSICAM-1412 7.9.1 Introduction The Intensicam-1412 is a special version of a 1412 camera in which a gated Gen III image intensifier is fiber-optically bonded to the front surface of the CCD. Due to the high luminous gain of the Intensifier tube, every incident photon generates thousands of electrons within the tube. Even under very low-light conditions, this results in a live image on the phosphor of the Intensifier, which is viewable by the CCD.
Fiber-optic module: This is used to couple the image that is generated on the phosphor of the image intensifier to the CCD. Since the optical format of the image intensifier is 1” and that of the CCD is 2/3”, a taper is used for the reduction. High voltage power supply: This is used to generate the voltages that are necessary for the performance of the image intensifier.
7.9.4 Intensicam & CView 1) In CView, there is an "Intensify" button on the control panel that is (by default) RED in color. As long as this button is RED, the Intensifier is gated OFF (to protect the camera). Although the camera is connected (and a frames/sec counter is visible in the LHS of the viewing window), the image will remain black.
Figure 7.10-1: Cooled (left) and non-cooled (right) multi-spectral cameras. A module equipped with a four-position multi-spectral filter wheel is integrated within a modified monochrome DVC-1412 camera housing (both TE-cooled and non-cooled versions are available). The filter module, can be supplied with high-quality CLEAR/IR-CUT, RED, GREEN, BLUE optical filter elements or with special application set.
7.10.1.2 Auto White Balance In order to make the white areas in the field of view appear to be white (R=G=B) in the super- imposed image most software applications use a calibration scan, in which R, G and B images are obtained to determine the relative strength of each component.
7.10.2 Spectral Response NOTE: the spectral response curves shown represent the R, G, B, clear configuration of the filter- set. Since the camera design allows the user to insert any filter-set of choice, this data may not be valid for user-configured cameras. Filters Blue Clear...

Removing the Filter Wheel Module 1) Remove the two 4/40" X 3/8" Allen-head screws which retain the module. a. These screws are the only silver-colored screws on the camera. b. Use a 3/32" socket head drive to remove the screws. 2) Disengage the filter wheel module.
Page 43
Removing the Filter 1) Using the filter-spring removal tool, grasp the tool with one hand, while holding the filter with the opposite hand. 2) Align the tool on top of the filter spring.
Page 44
3) Push and turn the tool while compressing the spring, so that the tabs on the tool go underneath the protrusions holding the filter spring. This process will disengage the filter. Rotate the tool until both the spring tabs and the tool are clear of the protrusions. 4) Remove the tool.
Page 45
5) Place a clean surface lens paper where you want the filter to fall upon. Turn the module up side down. This will cause the filter to fall out. Installing Filters 1) Identify the filter surface with a lip. This surface should face the bottom of the wheel.
Page 46
2) Drop the filter into the slot. 3) Identify the spring surface with the dot protrusions. The dot should face the top. 4) Drop the spring into the slot above the filter.

(LVDS and CameraLink Cameras) 9.1 INTRODUCTION The following is a definition of the serial control interface for the DVC-1310A/1312A/1412 cameras. Serial control is standard within all DVC131X cameras; it can be controlled via a communication program (such as Windows HyperTerminal) or within a larger program, such as C- View.
9.4 CAMERA CONTROLS The camera has the following parameters that can be controlled or queried via the serial port: 9.4.1 Gain The camera gain is controlled by means of an analog voltage (0-to-3VDC). This parameter is supplied by the host PC as a two digit hex data argument to the command GAI and converted to an analog voltage using an 8-bit Digital-to-Analog converter (DAC).
9.4.3 Exposure The 11bit argument of the EXP command sets the camera exposure by controlling an internal “exposure bus” which is made up of 11 data bits DB[10:0]. The power-on default value of EXP is 001. An exposure command with the syntax "EXP 7FF" would set the exposure to the maximum value (all bits set "High").
Page 55
In the PDP internal version of this mode, the microprocessor that controls the serial control interface generates a periodic pulse with a user-defined "low" duration (TIL command) and a user-defined "high" duration (TIH command). In the PDI internal version of this mode, the microprocessor that controls the serial control interface generates a one-shot pulse on the user’s command with a user-defined "low"...
Version: The VER (followed by a carriage return) command queries the camera and returns the characters DVC and a two byte hex code representing a "major revision" and a "minor revision". A typical response to the command VER is DVC7.6.
The following commands apply only to intensified cameras: Description Range of argument Output Code signals controlled {default} 00 ≤ two digit hex value ≤ FF Intensifier Gain Int_Gain DAC {00} Intensifier Pulse “ON” Duration 000 ≤ three digit hex value ≤ FFF SPI Latch {00} 00 ≤...
9.5.2 Notes on Intensifier Operation CAUTION: Do NOT point the intensifier at bright lights or permanent damage to the intensifier tube may result. • The INT_PULSE (which is a camera-internal signal) follows negative logic, i.e. the Intensifier is "off" when this pulse is HIGH; the Intensifier is "on" when this pulse is LOW. This pulse is used under s/ware control to protect the Intensifier against “photon overload”.
9.5.3 Notes on Wheel Commands The following commands apply only to DVC-1412 cameras that are equipped with a multi-spectral filter wheel; cameras that are not equipped with a wheel will respond to these commands with an error message.
