Image Acquisition Control AW0009760300098 Basler aviator GigE7.9 Maximum Allowed Frame RateIn general, the maximum allowed acquisition frame rate on any aviator camera may be limited byseveral factors: The amount of time that it takes to transmit an acquired frame from the camera to your hostPC. The amount of time needed to transmit a frame depends on the bandwidth assigned to thecamera. The setting for the sensor digitization taps feature. If this feature is set for four taps, you will beable to acquire frames at a higher rate than if it is set to one tap. The binning feature. If binning is enabled, the maximum allowed frame rate will increase. The setting for the prelines feature. If you use a higher prelines setting, you can acquire fewerframes per second. (This is especially true when a small AOI is used). The amount of time it takes to read an acquired frame out of the imaging sensor and into thecamera’s frame buffer. This time varies depending on the height of the frame. Frames with asmaller height take less time to read out of the sensor. The frame height is determined by thecamera’s AOI Height settings. The exposure time for acquired frames. If you use very long exposure times, you can acquirefewer frames per second.There are two ways that you can determine the maximum allowed acquisition frame rate with yourcurrent camera settings: You can use the online frame rate calculator found in the Support section of the Baslerwebsite:www.baslerweb.com You can use the Basler pylon API to read the value of the camera’s Resulting Frame Rate Absparameter (see the next page).Note that the maximum allowed frame rate decreases if the Image AOI issignificantly displaced from the sensor’s center. This is particularly true for adisplacement towards the upper part of the sensor.When the camera's acquisition mode is set to single frame, the maximum possibleacquisition frame rate for a given AOI cannot be achieved. This is true becausethe camera performs a complete internal setup cycle for each single frame andbecause it cannot be operated with "overlapped" exposure.To achieve the maximum possible acquisition frame rate, set the camera for thecontinuous acquisition mode and use "overlapped" exposure.For more information about overlapped exposure, see Section 7.6 on page 87.
