<description>The accuracy of frame timestamp synchronization between physical cameras</description>
The accuracy of the frame timestamp synchronization determines the physical cameras'
- ability to start exposure at the same time. If the sensorSyncType is CALIBRATED,
- the physical camera sensors usually run in master-slave mode so that their shutter
- time is synchronized. For APPROXIMATE sensorSyncType, the camera sensors usually run in
- master-master mode, and there could be offset between their start of exposure.
+ ability to start exposure at the same time. If the sensorSyncType is CALIBRATED, the
+ physical camera sensors usually run in leader/follower mode where one sensor generates a
+ timing signal for the other, so that their shutter time is synchronized. For APPROXIMATE
+ sensorSyncType, the camera sensors usually run in leader/leader mode, where both sensors
+ use their own timing generator, and there could be offset between their start of exposure.
In both cases, all images generated for a particular capture request still carry the same
timestamps, so that they can be used to look up the matching frame number and
