    Description of the data path 8.2.1 IBIS5A multiple slope (High Dynamic Range mode) The MF-131 sensor has a high dynamic range of about 60 dB. This can be extended to almost 100 dB by switching to a special mode. This mode is called dual (in the case of rolling shutter) or multiple slope mode (in the case of global shutter).
  • Page 55 Description of the data path It is important to notice that pixel signals above the dual slope reset level will be left unaffected (green P1 and green P2). The Marlin F131 offers up to three knee-points when in global shutter mode. This functionality is controlled via the following registers.

To correct a frame, a multiplier from 1...2 is calculated each pixel in 1/256 steps – this allows for shading to be compensated by up to 50 %. Besides generating shading data off-line and dow nloading it to the camera, the camera allows correction data to be generated au...
  • Page 71 Description of the data path After this, a search is made for the brightest pixel in the mean value frame. A factor is then calculated for each pixel to be multiplied by, giving it the gray va lue of the brightest pixel. ll of these multipliers are saved in a “shading reference image“.

  • Page 81: Binning (Ccd B/W Models)

    Description of the data path 8.12 Binning (CCD b/w models) Binning is the process of combining neighboring pixels while being read out from the CCD chip. All CCD equipped b/w Marlin models have this feature. Binning is used primarily for 3 reasons: A reduction in the number of pixels and thus the amount of data while retaining the original image area angle, an increase in the frame rate (vertical binning only),...

  • Page 82: Horizontal Binning

    Description of the data path This reduces vertical resolution, depending on the model. If vertical binning is activated the image may appear to be over-exposed and must be corrected.

    Controlling image capture Multi-Shot can also be combined with the external trigger in order to grab a certain number of images based on an external trigger. This is especially helpful in combination with the so called Deferred_Mode to limit the amount of grabbed images to the FIFO size. ISO_Enable / Free-Run Setting the MSB (bit 0) in the 614h register (ISO_ENA) puts the camera into ISO_Enable mode or Continuous_Shot.

  • Page 100: Jitter At Start Of Exposure

    Controlling image capture Jitter at start of exposure e following chapter discusses the latency time which exists for all CCD-models when either a hardware or software trigger is generated, until the actual image exposure starts. Owing to the well-known fact that an Interline Transfer CCD-sensor has both a light sensitive area and a separate storage area, it is common to interleave image exposure of a new frame and output that of the previous one.

  • Page 101: Frame Memory And Deferred Image Transport

    Controlling image capture Frame memory and deferred image transport An image is normally captured and transported in consecutive steps. The image is taken, read out from the sensor, digitized and sent over the 1394 bus. As all Marlin cameras are equipped with built in image memory, this order of events can be aused or delayed by using the deferred image transport feature.
