Camera on a conveyor belt a trigger delay is required to ensure that the image is not exposed until the part to be inspected passes in front of the NI 177x Smart Camera In this case specifying the trigger delay in terms of edge counts allows the NI 177x Smart Camera to expose the image when the part is in position regardless of changes in conveyor belt speed For other applications a delay specified in milliseconds is sufficient If you are strobing a light there is a delay of 500 us while the lighting controller turns on the light After the lighting turn on time the exposure begins The width of the exposure pulse determines how long the sensor is exposed The exposure time can be adjusted by setting the Exposure Time control in Vision Builder AI setting the ExposureTime attribute in LabVIEW or by setting the Exposure Time control in MAX The lighting strobe deasserts at the end of the exposure pulse The end of an exposure starts the image readout from the sensor The maximum trigger rate is determined by the maximum frame rate for your configuration Refer to the Maximum Frame Rate section for information about the factors that affect the maximum frame rate NI 177x Smart Camera User Manual 6 4 ni com Chapter 6 Image Acquisition Maximum Frame Rate Frame rate is the inverse of the frame period The frame period is the time from the start of exposure on one frame to the start of exposure on the next frame as shown in Figure
