Patent ID: 8310530

Claim:
A controller configured for use with an endoscopic system, the controller comprising: a phase lock loop circuit that is configured to receive a video synchronization signal from a first imaging sensor and to receive a video synchronization signal from a second imaging sensor to generate a video clock signal to send to the second imaging sensor, wherein the video clock signal is generated such that image frames of the imaging sensors have the same fundamental frequency and are phase locked, and wherein the first imaging sensor and a first light source face the second imaging sensor and a second light source; and a light source driver adapted to be connected to the second light source, wherein the light source driver is further connected to the phase lock loop circuit to receive the video clock signal, and wherein the first imaging sensor and the first light source are configured to be activated during a first time interval, and wherein the second imaging sensor and second light source are configured to be activated during a second time interval that is distinct from the first time interval.
