  • Page 16 OPERATING AND USER MANUAL QUARTZ series CXP The camera is able to average a number of images before they are output over the interface. This reduces the temporal noise significantly. Horizontal binning and vertical binning digitally averages a number of pixels into a single pixel. The used method is suitable to increase sensitivity.

  • Page 17: Control Of The Camera

    The exact address and interpretation of the value are camera specific. GenICam (Generic Interface for Cameras) is designed to bridge this. With CoaXPress frame grabbers a GenICam Application Programming Interface (GenAPI) is provided. This is a software layer that maps generic programming syntax onto the camera registers, using a description XML file.

  • Page 18: Structure Of Camera Control

    OPERATING AND USER MANUAL QUARTZ series CXP Structure of camera control The practical way to control the camera is closely dependant on the Frame grabber manufacturers’ software implementation and SDK. Most frame grabber manufacturers’ software provides a Graphical User Interface (GUI) that is automatically generated from the XML file.
  • Page 19 OPERATING AND USER MANUAL QUARTZ series CXP The following criteria’s have been used for the assignment of recommended visibility: • B: beginner - features that should be visible for all users via the GUI and API. The number of features with “beginner” visibility is limited to all basic features of the devices so the GUI display is well-arranged and is easy to use.

    In the Camera Link version of the Q-2A340 and Q-4A180 the Region of Interest is configurable with 4 parameters in a single command. In the CoaXPress version this is different and each of the 4 parameters has to be programmed separately into the camera. This is done through the commands Width, Height, OffsetX and OffsetY.
  • Page 24 6.3.2. Pixel format The CoaXPress interface does not require additional configuration on the frame grabber side. The frame grabber automatically detects the pixel format in order to be able to grab images correctly. The camera is configurable in 8 or 10 bit pixel data, for both the monochrome and the color version.
  • Page 25 Standard Adimec test pattern. I The Standard Adimec test pattern consists of various grey bars in the center and a boundary pattern near the edge of the image. In the color camera there are also color patches available, those patches are situated on the left and right side of the grey bars.

  • Page 26: Image Acquisition (Icategory: Acquisitioncontrol)

    OPERATING AND USER MANUAL QUARTZ series CXP Image acquisition (Icategory: AcquisitionControl) The Quartz cameras have a buffered pipeline architecture, in which a FIFO memory decouples the frame acquisition and the image interface transmission. Regardless of trigger mode, image data follow a path through roughly three building blocks that can have separate maximum data rates.
  • Page 27 OPERATING AND USER MANUAL QUARTZ series CXP 6.4.2. Interface image transmission speed CoaXPress exists at different data rates. On the Quartz the following data rates can be selected: CXP TYPE DATARATE PER CABLE (GB/S) CXP-1 1.25 CXP-2 CXP-3 3.125 CXP-5 CXP-6 6.25...

  • Page 29 OPERATING AND USER MANUAL QUARTZ series CXP 6.4.4. Burst mode As indicated at the start of in section 6.4, the decoupling of image acquisition and interface data transmission enables capturing a burst of images at a higher acquisition rate than the interface frame rate.
  • Page 30 OPERATING AND USER MANUAL QUARTZ series CXP Example: resolution 2048 x 512 @ 10 bit, CXP-6 single interface Applying the equations in sections 6.4.1 and 6.4.2: • The 2048 x 512 acquisition maximum frame rate is 707 fps. • The 2048 x 512, 10 bit CXP-6 single, transmission maximum frame rate is 453 fps. When BurstRequestMode is set to RequestModeAuto, the images are simultaneous to acquisition transmitted over the interface (at the maximum interface speed).
  • Page 31 The camera can be in acquisition state and in non-acquisition state. The latter state occurs after camera startup. Note that the CoaXPress standard requires certain settings to be changed when acquisition is stopped. In the Quartz cameras, for these setting changes the camera automatically stops and restarts acquisition with the setting change in between.
  • Page 32 In case of a TriggerActivation set to RisingEdge, the rising edge triggers the start of integration. There are three possible triggers: • The CoaXPress trigger. Trigger sequences have the highest priority. The frame grabber manufacturer is to facilitate software that allows to send the trigger.

  • Page 33: Flashstrobe Commands (Icategory: Counterandtimercontrol)

    OPERATING AND USER MANUAL QUARTZ series CXP The actual exposure time is: • TriggerWidth mode ExposureTime = cc1_pulse_length + Emin • Timed mode: ExposureTime = ExposureTimeRaw + Emin • SynchControl mode: ExposureTime = Frame_time; Latency of Emin • TimeTriggeredControl Mode: ExposureTime = ExposureTimeRaw + Emin The camera automatically checks the specified exposure time.

  • Page 34: Gain And Black Level (Icategory: Analogcontrol)

    OPERATING AND USER MANUAL QUARTZ series CXP Gain and black level (Icategory: AnalogControl) The GenICam AnalogControl is somewhat misleading for this section, originating from the GenICam lingo. In the camera, gain and black level can be adjusted but that is done in the digital domain. In both monochrome and Bayer cameras a gain applicable for all pixels is available.

  • Page 35: User Set (Icategory: Usersetcontrol)

    ICommand UserSetSave ICommand Built In Test (ICategory: Adimec) A built In Test (BIT) function in the camera verifies functions and signals critical errors when they arise. Some tests are run at camera start-up and others are continuously run. The build in test result is readable. If no failure is detected, it returns value 0. Each failure condition has a non-zero associated BIT return value, listed in table 6.5.

  • Page 36: Defect Pixel Correction (Icategory: Defectpixel)

    Defect pixel correction (ICategory: DefectPixel) In Quartz series cameras defect pixels are corrected in real time. Adimec does not release cameras with more than 1 adjacent defect pixel upon delivery. However, additional defect pixels can be user-programmed. Up to 2 adjacent pixels can be corrected. More than 2 adjacent defect pixels can be user programmed, but will not result in a reliable correction.

  • Page 43: High Dynamic Range Mode (Icaterogy: Multislope)

    OPERATING AND USER MANUAL QUARTZ series CXP 6.13 High Dynamic Range mode (ICaterogy: Multislope) In the camera, a high optical dynamic range can be realized setting the camera to a non-linear response. To be more precise, the response can be piece-wise linear with up to 3 slopes (see figure 6.7).
  • Page 44 OPERATING AND USER MANUAL QUARTZ series CXP The underlying principle of the multislope is in varying the pixel charge capacity of the sensor in steps. This can be done up to 3 times within a single exposure time to achieve a maximum of the 3 exposure slopes.
  • Page 45 OPERATING AND USER MANUAL QUARTZ series CXP The intermediate 2 multi slope levels and 2 multi slope times are expressed as a percentage from the normal saturation level and integration time. The node points are configurable by sequentially selecting them with the MultiSlopeNodeSelector. MultiSlopeLevel and MultiSlopeTime are read and written for the selected node.
