STV0974

Functional description

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.

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.
