Piranha HN RoHS User Manual 22 (fpn calibration) ccf cpa 2 16000 (prnu calibrated to an average pixel value of 4000) Command Categories The following diagram categorizes and lists all of the camera’s commands. This chapter is organized by command category.
Piranha HN RoHS User Manual 23 Sensor Output Format Selecting TDI or Area Mode Operation The Piranha HN-xx camera has the ability to operate in either TDI or Area Mode. In Area Mode, the camera operates as an area array camera using a two dimensional array of pixels. Area Mode is useful for aligning the camera to your web direction or when you need a rectangular 2D image and the lighting supports a full frame imager.
Piranha HN RoHS User Manual 24 Setting the Camera’s CCD Shift Direction Purpose: Syntax: Syntax Elements: When in TDI Mode, selects the forward or reverse CCD shift direction or external direction control. This accommodates object direction change on a web and allows you to mount the camera “upside down”. In Area Mode, selects the vertical readout direction. This allows you to mirror the image vertically or mount the camera “upside down”. scd i i • Notes: • Readout direction.
Piranha HN RoHS User Manual 25 Increasing Sensitivity with Binning Binning increases the camera’s light sensitivity by decreasing horizontal and/or vertical resolution—the charge collected by adjacent pixels is added together. Binning is also useful for increasing frame rate (vertical binning) or increasing the pixel pitch. For example, if you set your vertical binning to 2 and your horizontal binning to 2, your pixel size increases from 7µm x 7µm (no binning) to 14 µm x 14 µm (2 x 2 binning).
Piranha HN RoHS User Manual 26 Syntax: Syntax Elements: binning factor. Different frame grabber files are needed for different horizontal binning factors. sbh m m • Notes: Horizontal analog binning value. Available values are 1 (factory setting, no binning) 2, or 4. If you are using horizontal binning, the min, max, and mean statistics generated by the gl or gla command are for every second pixel (or valid data) only (e.g., if sbh 2, every second pixel).
Piranha HN RoHS User Manual Example: 27 • Changing binning values does not automatically alter gain, external frame rate generation, or other functions of the camera. • Pixel numbering remains unchanged for the roi, gl, gla, gfc , sfc , gpc, and spc commands. Refer to Figure 19 for an explanation of pixel numbering and pixel start and stop values when using a region of interest. • Command sbh set to default (1).
Piranha HN RoHS User Manual 28 Exposure Mode and Line/Frame Rate How to Set Exposure Mode and Line/Frame Rate You have a choice of operating the camera in one of two exposure modes. Depending on your mode of operation, the camera’s line/frame rate (synchronization) can be generated internally through the software command ssf or set externally with an EXSYNC signal (CC1). When operating in TDI Mode, it is important that the line rate used matches the web speed.
Piranha HN RoHS User Manual 29 Exposure Modes in Detail Mode 3: External Trigger, Maximum Exposure Time Figure 12: Mode 3 Timing Mode 7: Internal Frame Rate, Maximum Exposure Time In this mode, the frame rate is set internally using the ssf command with a maximum exposure time. Note: In TDI mode the frame period equals the line period.
Piranha HN RoHS User Manual 30 Setting Frame Rate Purpose: Syntax: Syntax Elements: Sets the camera’s frame rate in Hz. Camera must be operating in exposure mode 7. ssf i i Set the frame rate to a value from: TDI : 1-34246 Area : 1-130 Notes: Related Commands: Example: 03-032-20135-00 Value rounded up/down as required. The maximum line/frame rate is affected by horizontal and vertical binning factors, throughput setting, Camera Link mode, and number of CCD integration stages.
Piranha HN RoHS User Manual 31 Maximum Line Rate Calculations The maximum line rate in the camera is limited by either the Camera Link row time or the sensor row line time. The following calculations are used to determine the maximum line rate. Variables for calculations: • User.SOT = 80 | 160 | 320 | 640 • User.CLM = 2(3) | 15(16) | 21 • User.SBH = 1 | 2 | 4 • User.SDH = 1 | 2 | 4 • User.SBV = 1 | 2 | 4 • User.SDV = 1 | 2 | 4 • User.TDI = 0 | 1 • User.
Piranha HN RoHS User Manual 32 Camera Output Format How to Configure Camera Output The Piranha HN cameras offer great flexibility when configuring your camera output. Using the clm command, you determine the camera’s Camera Link configuration, number of output taps, and bit depth. Using the sot command, you determine the camera’s output rate. These two commands work together to determine your final camera output configuration.

Piranha HN RoHS User Manual 35 Setting the Camera Link Mode Purpose: Syntax: Syntax Elements: Notes: Related Commands Example: Sets the camera’s Camera Link configuration, number of Camera Link taps and data bit depth. Refer to the tables on the previous pages to determine which configurations are valid for your camera model and how this command relates to other camera configuration commands.
Piranha HN RoHS User Manual 36 Setting the Pixel Readout Direction Purpose: Syntax: Syntax Elements: Notes: Sets the tap readout from left to right or from right to left. This command is useful if the camera must be mounted upside down. smm i i • Readout direction. Allowable values are: 0 = All pixels are read out from left to right. 1 = All pixels are read out from right to left. To obtain the current readout direction, use the command gcp or get smm.
Piranha HN RoHS User Manual 37 Setting a Region of Interest Purpose: Syntax: Syntax Elements: Sets the pixel range used to collect the end-of-line statistics and sets the region of pixels used in the ccg, cpa, gl, gla, and ccf commands. In most applications, the field of view exceeds the required object size and these extraneous areas should be ignored. It is recommended that you set the region of interest a few pixels inside the actual useable image. roi x1 y1 x2 y2 x1 Column start number.
Piranha HN RoHS User Manual 38 Figure 18: Signal Processing Chain Digital Processing 1. Fixed pattern noise (FPN) calibration (calculated using the ccf command) is used to subtract away individual pixel dark current and dark offset. 2. Digital gain has 3 methods for adjusting the camera digital gain. The ccg command adjusts the digital gain for a gain target. The sg command allows the user to adjust the gain in dB. The sg command does not have a target component in the command algorithm.
Piranha HN RoHS User Manual 39 Setting the Camera Gain Calibrating Camera Gain Purpose: Syntax: Syntax Elements: Instead of manually setting the digital gain to a specific value, the camera can determine appropriate gain values. This command calculates and sets the digital gain. ccg i i Calculation target value in a range from 4096 to 16064 DN (14 bit LSB). Notes: Example: • The algorithm calculates the gain of the 8h tap to set the tap mean to the user target.
Piranha HN RoHS User Manual 40 Calibrating the Camera to Remove Non-Uniformity (Flat Field Correction) Flat Field Correction Overview This camera has the ability to calculate correction coefficients in order to remove non-uniformity in the image when operating in TDI Mode. This video correction operates on a pixel-by-pixel basis and implements a two point correction for each pixel.
Piranha HN RoHS User Manual 41 3. The camera is capable of operating under a range of 8 to 1, but will clip values larger than this ratio. 4. The brightest pixel should be slightly below the target output. 5. When 6.25% of pixels from a single row within the region of interest are clipped, flat field correction results may be inaccurate. 6. Correction results are valid only for the current stage selection. If you change the number of stages, it is recommended that you recalculate your coefficients.
Piranha HN RoHS User Manual 42 How to Perform Flat Field Correction 1 Setup the camera operating environment (ie. Line rate, CCD Shift Direction, exposure, offset, gain, etc) Digital Offset and gain. Background subtract values should be set to zero. (ssb 0, sab 0, ssg 0) NOTE: Select the User Set (ssn 1, 2, 3 or 4) Items highlighted in GREY are not necessary to perform, unless you require doing so. 2 Steps 1, 4 and 5 are usually only needed to be performed.
Piranha HN RoHS User Manual 43 Performing FPN Correction Syntax: Syntax: Notes: Related Commands: Example: Performs FPN correction and eliminates FPN noise by subtracting away individual pixel dark current. For a complete description on how to use this command, see the Flat Field Correction Overview. ccf • Before performing this command, stop all light from entering the camera. (Tip: cover lens with a lens cap.) • Perform FPN correction before PRNU correction.
Piranha HN RoHS User Manual 44 2 = Calculates the PRNU coefficients using the entered target value as shown below: 4 = Same calculation above, only in ROI. The calculation is performed for all sensor pixels but warnings are only applied to pixels in the region of interest. This algorithm is useful for achieving uniform output across multiple cameras.
Piranha HN RoHS User Manual Notes: Related Commands Example 45 Subtracted value in a range in DN from 0 to 16383 (14 bit LSB). • See the following section for details on the ssg command. ssg ssb 500 Setting Digital Gain Purpose: Improves signal output swing after a background subtract. When subtracting a digital value from the digital video signal, using the ssb command, the output can no longer reach its maximum.
Piranha HN RoHS User Manual 46 Saving and Restoring Settings Saving and Restoring Factory and User Settings Figure 19: Saving and Restoring Overview Factory Settings You can restore the original factory settings, including the factory calibrated pixel coefficient set, at any time using the command rfs. User Settings There are two main sets of user settings: Area Mode user settings and TDI Mode user settings.

Piranha HN RoHS User Manual 48 Restores the Factory User Settings Purpose: Syntax: Notes: Example: See also: Restores the factory user settings for the current direction to the current set number. rfs • Available in TDI or area mode for sets 1 to 4.
Piranha HN RoHS User Manual 49 Saving and Restoring PRNU and FPN Coefficients Pixel coefficient sets are saved separately for Forward and Reverse direction, depending on which direction the camera is operating in when the wpc or wfc command is issued. It is important that you save pixel coefficients before switching CCD shift direction or current coefficient values will be lost. START Note: Available in TDI Mode only. User issues wpc or wfc command.
Piranha HN RoHS User Manual 50 Rebooting the Camera The command rc reboots the camera. The camera starts up with the last saved settings and the baud rate used before reboot. Previously saved pixel coefficients are also restored. Diagnostics Generating a Test Pattern Purpose: Syntax: Syntax Elements: Notes: Example: Generate a test pattern to aid in system debugging. The test patterns are useful for verifying proper timing and connections between the camera and the frame grabber.
Piranha HN RoHS User Manual 51 Returning a Single Line of Video Purpose: Syntax: Syntax Elements: Returns a complete line of video (without pixel coefficients or test pattern) displaying one pixel value after another. It also displays the minimum, maximum, and mean value of the line sampled within the region of interest (the region of interest command is explained in Setting a Region of Interest).
Piranha HN RoHS User Manual 52 Notes: Related Commands: Example: ≤ x1 • If x2 then x2 is forced to be x1. • Analog gain, analog offset, digital offset, background subtract, and digital system gain are applied to the data.

Piranha HN RoHS User Manual 61 Appendix C: CCD Handling Instructions Electrostatic Discharge and the CCD Sensor Cameras contain charge-coupled device (CCD) image sensors, which are metal oxide semiconductor (MOS) devices and are susceptible to damage from electrostatic discharge (ESD). Electrostatic charge introduced to the sensor window surface can induce charge buildup on the underside of the window that cannot be readily dissipated by the dry nitrogen gas in the sensor package cavity.
Piranha HN RoHS User Manual 62 Cleaning the Sensor Window 1. Use compressed air to blow off loose particles. This step alone is usually sufficient to clean the sensor window. 2. If further cleaning is required, use a lens wiper moistened with alcohol or acetone. 3. We recommend using lint-free ESD-safe cloth wipers that do not contain particles that can scratch the window. The Anticon Gold 9”x 9” wiper made by Milliken is both ESD safe and suitable for class 100 environments.
