Reset Exposure Alignment
Sensor timing is reset to initiate exposure when a valid trigger is received. Readout is sequential to
exposure, reducing the maximum achievable frame rates. That is, a trigger received during
exposure or readout is ignored since data would be lost by performing a reset.
Sensor Exposure Timing: Sony Sensor Models
Nano-5G cameras with Sony sensors have general timing characteristics using synchronous
exposure mode, as described below.
