Principles and History of NBI


Narrow band imaging (NBI) is a method of image enhancement [1, 2]. Although it is classified as an “optical digital method,” it enhances images using optical technology, processing them in a different way to previous optical digital methods [3]. An understanding of the optical properties of living tissue was deeply involved in the development of NBI.
