1. A medical system comprising:
an endoscope, including:
a handle; and
a sheath having a first illumination source, a second illumination source, and an imaging device at a distal tip of the sheath, wherein the first illumination source is configured to emit white light, and wherein the second illumination source is configured to emit a red light;
a display device;
a controller configured to interface with the endoscope and the display device, wherein the controller includes:
a first control configured to allow a user to control a brightness of the first illumination source;
a second control configured to allow a user to control a brightness of the second illumination source, wherein the first control and the second control are configured to enable the user to control the brightness of the first illumination source and the brightness of the second illumination source independently of one another; and
a carrying case configured to contain the endoscope, the display device, and the controller;
wherein the controller is configured with a duty cycle such that the controller instructs (1) the first illumination source to emit a white light that pulses at a first frequency greater than that detectable by a human eye and (2) the second illumination source to emit a red light that pulses at a second frequency greater than that detectable by the human eye;
wherein the first frequency and the second frequency are such that, while a pulse of white light is emitted from the first illumination source, a pulse of non-white light is not emitted from the second illumination source, and while the pulse of non-white light is emitted from the second illumination source, the pulse of white light is not emitted from the first illumination source;
wherein the controller, the first illumination source, and the second illumination source are configured such that the first frequency and the second frequency cause the first illumination source and the second illumination source to emit light at alternating times; and
wherein a frame rate of the imaging device is such that, while the imaging device is capturing an image, the pulse of white light is emitted, and wherein the imaging device captures images only when the first illumination source is emitting the pulse of white light.
