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

In a multiple viewing elements endoscope, fuzziness and blur in the images due to movement of the endoscope is reduced by using flashing illuminators instead of continuous illumination. In one embodiment, LED illuminators are flashed at high intensity and for a very short duration. To address interlacing artifacts, LEDs are flashed once at the end of a field and again at the beginning of the following field to minimize the time difference between the capture of the two fields. In another embodiment, the LEDs are flashed once wherein the single flash overlaps the end of a field and the beginning of the following field. In some embodiments, still images may be captured with fine detail by pressing a button on the endoscope handle which activates the LEDs to flash along with the capture of an image. In one embodiment, pressing a button for still image capture results in the capture of two fields, each accompanied by a flash, which are interlaced to form a single still image frame.

Method and system for eliminating image motion blur in a multiple viewing elements endoscope

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.
