A capsule endoscope device, system and method for dynamically adjusting a color illumination spectrum. A plurality of different color groups of LEDs may emit light, recorded by an image sensor, corresponding to a plurality of different respective wavelength subranges. A driving circuit may send a driving current to independently activate each different color group of LEDs during entirely or partially non-overlapping time pulses. A single color group of LEDs is independently activated at any one time, and the plurality of different color groups of LEDs are sequentially activated in successive time pulses to simulate a white light or multi-color illumination spectrum over a plurality of the time pulses. The activation pattern of the color groups of LEDs may be dynamically adjusted, in real-time, to achieve a flexible and customizable illumination spectrum ideal for imaging a variety of different environments e.g., in the GI tract.

Methods and systems are provided to generate metamerically matched illumination on a surgical site. The metamerically matched illumination may reduce or remove strobing effects associated with illumination devices during a surgery or surgical procedure. By metamerically matching illuminants in the illumination in combination with estimates of the human visual system, the illumination of the surgical site can visually appear to a user as a continuous white light, while maintaining distinct underlying spectra in the illumination. The light reflected by the surgical object may also be captured and metamerically matched, such that the reflected light appears as a single continuous color.

This disclosure relates to instruments and methods of performing an endoscopy. An endoscope for producing images of a surgery in vivo may include a hub and an imaging rod extending from the hub, the imaging rod being configured to receive light and direct the light to an imaging sensor located adjacent to a distal end of the imaging rod, the hub and the imaging rod being attached to form an assembly having a center of mass established distally of the hub. In other implementations, the hub may be omitted.
