Parameter Description

This parameter allows to select the method used by MultiCam to calculate the Exposure Delay value for P1 and P2 programs.

By default, MultiCam configures P1 and P2 with the smallest possible Exposure Delay value. This setting is satisfactory for the use cases where the exposure time is shorter than the readout time.

Optionally, keeping ExposureDelayControl set to MAN, allows to change the minimum exposure delay value of P1 and/or P2 using the ExposureDelay_MAN_P1_us and ExposureDelay_MAN_P2_us parameters.

Alternatively, you may also change ExposureDelayControl to one of the automatic control methods: SAME_START_EXPOSURE or SAME_END_EXPOSURE.

With SAME_START_EXPOSURE, the start of exposure is delayed by the same amount of time for both programs: both exposure delay values are equal.

With SAME_END_EXPOSURE the end of exposure is delayed by the same amount of time for both programs.

The effective exposure delay values, calculated by MultiCam are reported by ExposureDelay_P1_Effective_us and ExposureDelay_P2_Effective_us parameters.

Parameter Usage
