Abstract: Methods and apparatuses are disclosed for reducing power consumption in image processing systems comprising a master image sensor and a slave image sensor synchronized to the master image sensor. For example, a synchronization signal may be periodically sent from the master image sensor to the slave image sensor, where the synchronization signal is sent once per synchronization period and indicates a frame start time. A time may be estimated to complete an image processing operation. A comparison may be made between the estimated time and the synchronization period, and a frame capture rate of the slave image sensor may be selectively adjusted based at least in part on the comparison.
