Super resolution and color motion artifact correction in a pulsed color imaging system
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 first wavelength range that comprises a first 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;
detecting motion of objects being imaged;
increasing resolution for the pixel array by compensating for the detected motion by;
sensing luminescence of a plurality of neighboring pixels to gather luminance data,bilinear interpolating the luminance data into a first upscaled data set,bicubic interpolating the luminance data into a second upscaled data set, andcreating a baseline with no interpolation of the luminance data into a third upscaled data set; and
creating a stream of images by combining a plurality of sensed reflected electromagnetic energies into a frame.
