<p>A flash module 200 has a first light-emitting diode ("LED") 202 optically coupled to a first lens 212 having a first viewing angle, and a second LED 204 optically coupled to a second lens 214 having a second viewing angle. The second viewing angle is greater than the first viewing angle. A first control signal line coupled to the first LED allows selectively activating the first LED. A second control signal line coupled to the second LED activates the second LED. The first and second LEDs may respectively emit blue and red light, with a third LED 206 emitting green light.</p> |
