STV0974
Idle to viewfinder / live The sensor field and line lengths are set according to user-defined frame
rate and data output format. The STV0974 processes all sensor data on the fly. Exposure and white
balance controls are computed at the end of each frame.
Figure 23: Idle to viewfinder or live
Viewfinder / live to idle
The STV0974 processes all the frame data and switches to idle mode after the last byte.

t0: Time to interpret Mode change command (< 1ms)
t1: Time to set VF or Live parameters inside the STV0974 and to send VF or Live settings to the sensor (~2ms)
t2: Time to go from Idle to Video Active state (Sensor side)
t3: Exposure time (Sensor side). It depends on the frame rate.
