Falcon 4M Camera Manual 26 3.3.3 Setting the Camera Link Strobe Frequency Purpose: Sets the camera link strobe frequency. Refer to the How to Configure Camera Output section, above, for a description of how camera link strobe frequency relate to the camera’s Camera Link mode.
Falcon 4M Camera Manual readout in parallel the Falcon 4M60 camera is capable of reaching 60fps. A timing diagram helps to explain this mode of operation. Concurrent Mode Timing Diagram In concurrent mode, a low-to-high transition in the EXSYNC signal starts the integration time, and a high-to-low transition in the EXSYNC signal starts the readout of image data.
Falcon 4M Camera Manual 28 3.4.2 Setting the Exposure Mode Purpose: Sets the camera’s exposure mode allowing you to control your sync, exposure time, and frame rate generation. Syntax: sem m Syntax Elements: m Exposure mode to use. Factory default setting is 2. Notes: Refer to • Exposure Modes for a quick list of available modes or to the following sections for a more detailed explanation. • To obtain the current value of the exposure mode, use the command gcp.
Falcon 4M Camera Manual Exposure Modes in Detail Mode 2: Internally Programmable Frame Rate and Exposure Time (Default) The parameter being programmed (i.e. frame rate or exposure time) will be the driving factor so that when setting the frame rate, exposure time will decrease, if necessary, to accommodate the new frame rate. In reverse, the frame rate is decreased, if necessary, when the exposure time entered is greater than the frame period.
Falcon 4M Camera Manual 30 Mode 4: Smart EXSYNC, External Frame Rate and Exposure Time In this mode, EXSYNC sets both the frame period and the exposure time. The rising edge of EXSYNC marks the beginning of the exposure and the falling edge initiates readout. Refer to the Allowable Exposure Time Increments table on page 32 for details on minimum exposure time increments for this mode. Figure 11: Mode 4.
Falcon 4M Camera Manual 3.4.2 Setting the Frame Rate Purpose: Syntax: Sets the camera’s frame rate in frames per second (Hz). Syntax Elements: f ssf f Set the frame rate in Hz in a range from 1-60.4 (4M60 full frame, 80 MHz cameralink strobe, efd 1) or 1-30.6 (4M30 full frame, 80 MHz cameralink strobe, efd 1). Range increases when using a vertical window of interest. Notes: • Camera must be operating in exposure mode 2.
Falcon 4M Camera Manual 32 Allowable Exposure Time Increments Camera Link Mode Allowable Exposure Time Increments (clm command) 15 or 16 18.513 µs (80/65 MHz camera link strobe) when exposure time overlaps frame readout 1 µs when exposure time does not overlap frame readout 2 or 3 37.038 µs (80 MHz camera link strobe) when exposure time overlaps frame readout 45.
Falcon 4M Camera Manual 3.5 Snapshot Modes Purpose: Optimizes camera timing for specific EXSYNC situations. Syntax: efd i Syntax Elements: i Snapshot mode.
Falcon 4M Camera Manual 34 Snapshot Mode The Falcon 4M60 and Falcon 4M30 cameras include a feature called Snapshot Mode. Snapshot Modes 1 and 2 allow the camera to produce usable images when intervals between EXSYNCs are large (>200 ms). Previously only snapshot mode 0 was available (no fast frame dump) which would eventually result in a completely saturated ‘first’ image after a very long EXSYNC idle period (seconds), as shown below.
Falcon 4M Camera Manual Snapshot Mode 1. Exposure concurrent with readout is allowed If, having a minimum integration time of about 500 us is not acceptable, then Snapshot Mode 2 can be used, below, which allows for integration times as low as 10 us at the expense of concurrent integration and readout. Therefore, it is recommended to only use Snapshot Mode 2 if your integration time must be below 500 us. This is also the reason why Snapshot Mode 1 is the default mode.
Falcon 4M Camera Manual The following timing diagrams show how the timing changes when snapshot modes are enabled in sem 2. sem 2, Snapshot Mode 1 (fast frame dump at falling edge of EXSYNC) sem 2,.
Falcon 4M Camera Manual Determining the Y parameter As mentioned, the Y parameter is around 500 us. The Y parameter depends upon the number of rows used, whether the camera outputs at 80 MHz or 65 MHz, and whether the camera being used is in 2 tap mode (Falcon 4M30) or 4 tap mode (Falcon 4M60). To obtain the Y parameter, execute the gcp command. The camera should respond and state: “Frame Dump Time: 487.5 us”. The 487.
Falcon 4M Camera Manual 38 Set Number of Frame Dumps Purpose: Sets the number of fast-frame dumps to be used within snapshot modes 1 or 2. Syntax: snd i Syntax Elements: i Set number of frame dumps. 1-7 Only enabled during Snapshot modes (efd) 1 or 2. Notes: Example: snd 3 When within snapshots modes 1 and 2 the user can choose to perform more than one fast frame dump during a dump sequence.
Falcon 4M Camera Manual The following graph illustrates the relationship of maximum frame rate versus sequence size.

Falcon 4M Camera Manual 42 3.7 Flat Field Correction This camera has the ability to calculate correction coefficients in order to remove nonuniformity in the image. This video correction operates on a pixel-by-pixel basis and implements a two point correction for each pixel.
Falcon 4M Camera Manual 3) When 6.25% of pixels from a single row within the region of interest are clipped, flat field correction results may be inaccurate. 4) Correction results are valid only for the current analog offset values. If you change this value, it is recommended that you recalculate your coefficients.
Falcon 4M Camera Manual 44 6) How can one match gain and offset values on multiple cameras? One way is of course to use flat field correction. All cameras would be set up under the same conditions including lighting and then calibrated with ccf and cpa. This can be time-consuming and complicated (especially the white target).
Falcon 4M Camera Manual 3.7.1 Selecting Factory or User Coefficients Purpose: Selects the coefficient set to use. The camera ships with a factory calibrated set of FPN and PRNU coefficients. The factory coefficients cannot be erased or modified. Syntax: csn i Syntax Elements: i Coefficient set number to use. 0-7 = Factory calibrated sets of FPN and PRNU coefficients. These coefficients cannot be erased or modified. 8-15 = User calibrated sets of FPN and PRNU coefficients.
Falcon 4M Camera Manual 46 3.7.3 Selecting the Calibration Sample Size Setting the Number of Frames to Sample Purpose: Sets the number of frames to sample when performing pixel coefficient calculations. Higher values cause calibration to take longer but provide the most accurate results. Syntax: css i Syntax Elements: i Number of lines to sample. Allowable values are 32, 64, 128 (factory setting), 256, 512, or 1024. Notes: Example: To return the current setting, use the gcp command. css 1024 3.7.
Falcon 4M Camera Manual Calibrating Individual Pixels Purpose: Syntax Sets an individual pixel’s FPN coefficient. Syntax Elements: x sfc x y i The pixel column number from 1 to 2352. y The pixel row number from 1 to 1728. i Coefficient value in a range from 0 to 1023. Notes: Example: DALSA The sfc command is not available when the camera is using the factory calibrated coefficients (csn 0-7). You must select the user coefficient set (csn 8-15) before you can perform FPN calibration.
Falcon 4M Camera Manual 48 3.7.5 Performing PRNU Calibration Purpose: Performs PRNU calibration to a targeted, user defined value and eliminates the difference in responsivity between the most and least sensitive pixel creating a uniform response to light. Using this command, you must provide a calibration target. Executing these algorithms causes the ssb command to be set to 0 (no background subtraction) and the ssg command to 4096 (unity digital gain).
Falcon 4M Camera Manual Calibrating Individual Pixels Purpose: Syntax Sets an individual pixel’s PRNU coefficient. Syntax Elements: x spc x y i The pixel column number from 1 to 2352. y The pixel row number from 1 to 1728. i Coefficient value in a range from 0 to 12287 where PRNU multiplier = 1 + ( Notes: Example: i ) 4096 The spc command is not available when the camera is using the factory calibrated coefficients (csn 0-7).
Falcon 4M Camera Manual 50 Loading Pixel Coefficients Purpose: Loads the last saved user coefficients or original factory coefficients from non-volatile memory. Syntax: lpc Notes: Example: The coefficient set that you are loading is determined by the csn value. Refer to the section, Selecting Factory or User Settings, for an explanation of the csn command. To return the current csn number, send the command get csn.
Falcon 4M Camera Manual 3.8 Offset and Gain Adjustments Setting Analog Offset Purpose: Syntax: sao t i Sets the analog offset. Syntax Elements: t Tap selection. Allowable value is 0 for all taps. i Analog offset value. Extreme range is 0 - 511 but dynamic range is dependent of the camera’s current exposure mode and gain settings. A value of 100 does not equal an offset of 100DN. Notes: Example: • When flat field correction is enabled the expectation is that in the dark the signal level is 0DN.
Falcon 4M Camera Manual 52 Subtracting Background Purpose: Use the background subtract command if you want to improve your image in a low contrast scene. It is useful for systems that process 8 bit data but want to take advantage of the camera’s 10 bit digital processing chain. You should try to make your darkest pixel in the scene equal to zero. Syntax: ssb t i Syntax Elements: t Sensor tap selection. Allowable range is 1 to 2, or 0 for all taps. i Subtracted value in a range in DN from 0 to 511.
Falcon 4M Camera Manual Setting Digital System Gain Purpose: 1) 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. Use this command to correct for this where: max output value ssg value = max output value - ssb value 2) Increases/decreases the camera's responsivity by increasing/decreasing the digital gain.
Falcon 4M Camera Manual 54 3.9 Generating a Test Pattern 03-032-20044-01 Purpose: Generates a test pattern to aid in system debugging.
