YCbCr pulsed illumination scheme in a light deficient environment
First Claim
Patent Images
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.
