Abstract: There is provided a method for enhancing endoscopic image data, comprising the steps of: (a) receiving a plurality of image frames from an imaging section of an endoscope apparatus at a predetermined frame rate; (b) converting said plurality of image frames into a plurality of digital image frames at said predetermined frame rate; (c) applying at least one active Look-up-Table, comprising at least one first transform, to at least part of said plurality of digital image frames at said predetermined frame rate, so as to generate a plurality of enhanced digital image frames; (d) providing said enhanced digital image frames to a display at said predetermined frame rate; (e) generating at least one optimised Look-up-Table, comprising at least one second transform that is optimised utilizing at least one image parameter of a predetermined quantity of said plurality of digital image frames; (f) updating said at least one active Look-up-Table with said at least one second transform; (g) executing step (c) for said pr
