T4: The sensor timing sequence delay, the internal exposure of the sensor is aligned with the row timing
sequence, so T4 has a maximum row cycle jitter. The value of each sensor is different. Some products
with large delay time (several hundred μs or more) have additional configuration time counted in T4.

Figure 8-19 Exposure delay
The following table shows the total exposure delay time for each sensor.
T1 is calculated according to the typical delay (5μs) of line0. If it is line2/3, T1 can be ignored.
T2 is calculated as 0
μs.
T3 is calculated as 0μs.
T4 is calculated according to the ROI settings and features of each sensor.
The exposure delay data for each model is as follows:
