Page 16: Choosing A Pull-Up Resistor
This section provides an overview of the ISC-178x image sensors, field of view, and imaging settings. All models of the ISC-178x use ON Semiconductor Python NOIP1SN or NOIP1SE sensors. ISC-178x are available with the following resolution configurations. 16 | ni.com | ISC-178x User Manual...

ISC-178x Resolution Configurations Model Resolution ISC-1780 640 x 480 ISC-1781 1280 x 1024 ISC-1782 1920 x 1200 ISC-1783 2592 x 2048 Field of View The field of view is the area under inspection that will be imaged by the ISC-178x. It is critical to ensure that the field of view of your system includes the object you want to inspect.
Page 18 Gain is a multiplier applied to the analog signal prior to digitization. Increasing the gain increases the amplitude of the signal. Gain allows you to trade off between making smaller signals more visible at the cost of increased noise and no longer being able to differentiate 18 | ni.com | ISC-178x User Manual...
Page 19 between larger signals. For most applications, the ISC-178x default gain setting optimizes the balance between small signals and large signals. Figure 17. Effect of Gain on the Video Signal 1. Low Gain 2. Medium Gain 3. High Gain In figure A, low gain has been applied to the signal. The pixel values in the image are grouped close together.
Page 20: Acquiring Images
In both cases, the ISC-178x can acquire images at up to the maximum frame rate. Related Information Connecting to Lighting Devices on page 12 Determining the Maximum Frame Rate on page 22 20 | ni.com | ISC-178x User Manual...
Page 21 Internal Timing The ISC-178x features two types of internally-timed modes: free-run mode and fixed-frame- rate mode. In free-run mode, the device acquires images at the maximum frame rate allowed by the configuration. To operate in free-run mode, the Trigger Mode must be set to Off. In fixed-frame-rate mode, you can specify a frame rate that is less than or equal to the maximum frame rate.
Page 22 You can determine the maximum frame rate for your configuration in software by reading the Max Frame Rate indicator in Vision Builder AI, reading the AcquisitionFrameRateLimit attribute in LabVIEW, or reading the Max Frame Rate indicator in MAX. 22 | ni.com | ISC-178x User Manual...
Page 23 Do not trigger faster than the maximum frame rate. If a trigger occurs faster than the maximum frame rate, such as the time between triggers being less than the minimum frame period, the incoming trigger is ignored. Software determines the maximum frame rate using the following equation: max frame rate = min frame period where...
Page 24: Exposure And Lighting
Additionally, in many environments, the ambient light conditions vary too significantly to obtain consistent results without adding dedicated lighting. For example, in a building with 24 | ni.com | ISC-178x User Manual...
Page 25: Image Readout
windows, the ambient light can vary significantly with weather. Also, standard fluorescent lighting flickers at a rate that is perceivable by the ISC-178x. In these situations, the ambient light must be overridden with a dedicated light source to ensure reproducible results. The Lighting Strobe starts after the Trigger Delay is satisfied.
