1. An endoscopic method for providing visualization to a light deficient environment comprising:
actuating an emitter to emit a plurality of pulses of electromagnetic radiation;
wherein the emitter comprises a visible source of electromagnetic radiation and one or more multispectral sources of electromagnetic radiation for eliciting a spectral response from one or more tissues;
sensing reflected electromagnetic radiation resulting from the plurality of pulses of electromagnetic radiation with a pixel array of an image sensor to generate a plurality of exposure frames;
detecting motion across two or more sequential exposure frames of the plurality of exposure frames;
compensating for the detected motion; and
combining the two or more sequential exposure frames to generate an image frame;
wherein at least a portion of the plurality of pulses of electromagnetic radiation emitted by the emitter comprises electromagnetic radiation having a wavelength from 900 nm to 1000 nm and one or more of:
electromagnetic radiation having a wavelength from 513 nm to 545 nm; or
electromagnetic radiation having a wavelength from 565 nm to 585 nm.
