Retry Function
This function repeats the Scan (with a single measurement trigger) until the overall judgment is OK.
The retry function has four modes: normal retry, exposure retry (*1), scene retry, and trigger retry.
*1: The brightness (exposure) depends on the shutter speed and gain. When HDR is ON, the shutter speed and gain are automatically
adjusted for the optimum exposure. When HDR is OFF, the gain is fixed.
