  • Page 54: Trigger Delay

    Camera interfaces Trigger delay Since firmware version 2.03, the cameras feature various ways to delay image capture based on external trigger. With IIDC V1.31 there is a standard CSR at Register F0F00534/834h to control a delay up to FFFh x timebase value. The following table explains the inquiry register and the meaning of the various bits.

  • Page 67: Ibis5A Multiple Slope (High Dynamic Range Mode)

    Description of the data path IBIS5A multiple slope (High Dynamic Range mode) The MARLIN F-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 68: Marlin F-131 With Three Knee-Points

    Description of the data path This dual slope reset pulse resets the analogue signal of the pixels below the dual slope reset level to this level. After the reset, the analogue signal starts to decrease with the same slope as before (pink P3 and yellow P4 lines). This introduces a knee-point in the exposure function.

  • Page 70: White Balance

    Description of the data path White balance Marlin color cameras have both manual and automatic white balance. White balance is applied so that non-colored image parts are displayed non-col- ored. White balance does not use the so called PxGA® (Pixel Gain Amplifier) of the analog front end (AFE) but a digital representation in the FPGA in order to modify the gain of the two channels with lower output by +9.5 dB (in 106 steps) relative to the channel with highest output.

The camera automatically generates frames, based on the current settings of all registers (GAIN, OFFSET, SHUTTER, etc.).

  • Page 73: Automatic White Balance

However, if there is a pause of >10 seconds between capturing individual frames this process is aborted. The following flow diagram illustrates the automatic white balance sequence.

  • Page 74 Description of the data path Note If the adjustment fails and the work area size and/or position becomes invalid this feature is automatically switched off - make sure to read back the ON_OFF flag if this feature doesn't work as expected. Within this area, the R-G-B component values of the samples are added and used as actual values for the feedback.

  • Page 75: Auto Shutter

    Description of the data path Auto shutter In combination with auto white balance, all Marlin CCD models and CMOS models are equipped with auto shutter feature. When enabled, the auto shutter adjusts the shutter within the default shutter limits or within those set in advanced register F1000360h in order to reach the reference brightness set in auto exposure register.
  • Page 76 Description of the data path To configure this feature in control and status register (CSR): Register Name Field Description 0xF0F0081C SHUTTER Presence_Inq Presence of this feature: 0: N/A 1: Available Abs_Control Absolute value control O: Control with value in the Value field 1: Control with value in the Absolute value If this bit= 1 the value in the Value field will be ignored.
  • Page 77 Description of the data path Note • Values can only be changed within the limits of shutter CSR. • Changes in auto exposure register only have an effect when auto shutter is enabled. • Auto exposure limits are: 50..205 (SmartView Ctrl1 tab: Target grey level) When both auto shutter and auto gain are enabled, priority is given to increasing shutter when brightness decreases.

  • Page 78: Auto Gain

    Description of the data path Auto gain In combination with auto white balance, all Marlin CCD models are equipped with auto gain feature. When enabled auto gain adjusts the gain within the default gain limits (see Table 33: Manual gain range of the various Marlin types on page 80) or within the limits set in advanced register F1000370h in order to reach the bright- ness set in auto exposure register as reference.

  • Page 81 Description of the data path Note • Setting the gain does not change the offset (black value) for CCD models. • Setting the gain changes the offset (black value) for CMOS models. This is due to the lack of black clamping circuitry in sensor.

  • Page 82: Look-Up Table (Lut) And Gamma Function

    Description of the data path Look-up table (LUT) and gamma function The AVT Marlin camera provides one user-defined look-up table (LUT). The use of this LUT allows any function (in the form Output = F(Input)) to be stored in the camera's RAM and to apply it on the individual pixels of an image at run-time.

  • Page 83: Loading An Lut Into The Camera

    Description of the data path Note • The input value is the most significant 10-bit value from the digitizer. The gamma LUT of the CCD models outputs the most significant 8 bit as shown above. • As gamma correction for the CCD models is also imple- mented via the look-up table, it is not possible to use a different LUT when gamma correction is enabled.

  • Page 84: Shading Correction

    Description of the data path Shading correction Shading correction is used to compensate for non-homogeneities caused by lighting or optical characteristics within specified ranges. To correct a frame, a multiplier from 1...2 is calculated for each pixel in 1/256 steps: this allows for shading to be compensated by up to 50 %. Besides generating shading data off-line and downloading it to the camera, the camera allows correction data to be generated automatically in the cam- era itself.

  • Page 85: Automatic Generation Of Correction Data

    Description of the data path Automatic generation of correction data Requirements Shading correction compensates for non-homogeneities by giving all pixels the same gray value as the brightest pixel. This means that only the back- ground must be visible and the brightest pixel has a gray value of less than 255 when automatic generation of shading data is started.
  • Page 86 Description of the data path Note Configuration To configure this feature in an advanced register: See Table 108: Advanced register: Shading on page 214. Note • The maximum value of GRAB_COUNT depends on the type of camera and the number of frame buffers that exist.

  • Page 95: Vertical Binning

    Description of the data path Vertical binning Vertical binning increases the light sensitivity of the camera by a factor of two by adding together the values of two adjoining vertical pixels output as a single pixel.

    Description of the data path Horizontal binning Definition In horizontal binning adjacent horizontal pixels in a line are combined in pairs. 2 x horizontal binning: 2 pixel signals from 2 horizontal neighboring pixels are combined.

For all mod- els this shutter is a global shutter; meaning that all pixels are exposed to the light at the same moment and for the same time span. Continuous mode In continuous modes the shutter is opened shortly before the vertical reset happens, thus acting in a frame-synchronous way.

A distinction is made as follows: FVal is active the sensor is reading out, the camera is busy In this case the camera must not change horizontal timing so that the trigger event is synchronized with the current horizontal clock.

    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. Deferred image transport As all Marlin cameras are equipped with built in image memory, this order of events can be paused or delayed by using the deferred image transport fea- ture.

    How does bandwidth affect the frame rate? How does bandwidth affect the frame rate? In some modes the IEEE 1394a bus limits the attainable frame rate. Accord- ing to the 1394a specification on isochronous transfer, the largest data pay- load size of 4096 bytes per 125 µs cycle is possible with bandwidth of 400 Mbit/s.
