1. A digital imaging method for use with an endoscope in ambient light deficient environments comprising:

  • actuating an emitter to emit a pulse of a wavelength of electromagnetic radiation to cause illumination within the light deficient environment;

    wherein said pulse is within a wavelength range that comprises a portion of electromagnetic spectrum;

    pulsing said emitter at a predetermined interval;

    sensing reflected electromagnetic radiation from said pulse with a pixel array;

    wherein said pixel array is actuated at a sensing interval that corresponds to the pulse interval of said emitter; and

    synchronizing the emitter and the imaging sensor so as to produce a plurality of image frames wherein the plurality of image frames comprises a luminance frame comprising luminance image data only and a chrominance frame comprising chrominance data only that are combined to form a color image.
