A pair of CMOS image sensors is provided. One of the pair of CMOS image sensors is assigned as a master CMOS image sensor and the other is assigned as a slave CMOS image sensor. The slave CMOS image sensor is synchronized to the master CMOS image sensor during image data acquisition. In one embodiment, the master CMOS image sensor and the slave CMOS image sensor are connected to receive a control signal, which assigns the master CMOS image sensor as master and the slave CMOS image sensor as slave. In another embodiment, the master CMOS image sensor and slave CMOS image sensor are hardwired to assign the master and slave. In yet another embodiment, the data signals from the master CMOS image sensor and slave CMOS image sensor are interleaved.
