Systems and methods of tracking the position of an endoscope within a patient's body during an endoscopic procedure is disclosed. The devices and methods include determining a position of the endoscope within the patient in the endoscope's coordinate system, capturing in an image fiducial markers attached to the endoscope by an external optical tracker, transforming the captured fiducial markers from the endoscope's coordinate system to the optical tracker's coordinate system, projecting a virtual image of the endoscope on a model of the patient's organ, and projecting or displaying the combined image.

Systems and methods of enhancing images use a contrast limited adaptive histogram equalization (CLAHE) algorithm in a field programmable gate array (FPGA). The images may be obtained by the imaging elements of a multiple imaging elements endoscope of an endoscopy system.

Endoscopic image enhancement using contrast limited adaptive histogram equalization (CLAHE) implemented in a processor

The present specification describes a system and method for computing the temperature of the tip of a multiple viewing elements endoscope based on a measurement of junction temperatures of light emitting diode (LED) illuminators inside the tip. The measurement of temperature is used for taking corrective action if the temperature exceeds a limit. The temperature measurement is used for optimizing image parameters, as the performance of image sensors is affected by changes in ambient temperature.

Systems and methods for regulating temperature and illumination intensity at the distal tip of an endoscope

A system and method of repositioning a region of interest within an endoscopic image from a first location to a target location on the display screen of an endoscopy system is provided. The endoscopy system includes an insertion portion having a tip section with at least one viewing element for capturing images of a body cavity having the region of interest. The method includes detecting a region of interest within a body cavity, displaying the region of interest on a display screen in communication with the endoscopy system, marking the region of interest on the display screen, selecting a target location on the display screen, estimating a transformation to be applied to the region of interest, and applying the estimated transformation for causing the region of interest to be displayed at the target location of the display screen.

An endoscope video processing system applies a blooming control feature to image frames of video data signals generated by viewing elements in the endoscope tip. A reduced digital gain is applied to a luminance (Y) component of the video data signal to generate an attenuated signal. An average luminance value of pixels neighboring a pixel of the attenuated signal is calculated and a function of the average luminance value is determined to generate a smoothly transitioning digital gain. The smoothly transitioning digital gain is conditioned using weights to generate a customizable digital gain, and the customizable digital gain is applied to the attenuated signal. This Local Blooming Control (LBC) facilitates a higher luminance digital gain in darker portions while maintaining a low or no luminance digital gain in brighter portions, within the same image frame.
