hello alejandro.concepcion,
syncSensor sample is a software approach of software based synchronization,
this example using multiple sensor per single capture session method, which means it’ll duplicate single capture request to these camera sensors.
hence, you should expect these two capture results to be close enough.
in addition, you may also refer to getSensorTimestamp() to gather sensor hardware timestamp, please have implementation of timestamp comparison from user-space to achieve synchronization results.
BTW,
please also check similar discussion threads, such as Topic 1061467, and Topic 1007933 for reference.
thanks
