1. A medical device configured for insertion into a body, comprising:
- an elongate member extending from a proximal end to a distal end, the distal end configured to be positioned inside the body;
an imaging device positioned at the distal end and configured to detect an image pattern;
a plurality of light sources positioned at the distal end, wherein each light source illuminates a different region, and the regions together form the image pattern; and
a control device having a processor configured to execute instructions that automatically control each light source of the plurality of light sources to deliver light based on the detected image pattern according to a preset illumination pattern, wherein the control device is configured to detect a difference in illumination among the regions, adjust an intensity of each light source until the differences in illumination among the regions are within a threshold, and automatically vary a characteristic of light directed through a first light source of the plurality of light sources independent of a characteristic of light directed through a second light source of the plurality of light sources based on the detected image pattern.

Abstract
A medical device, configured for insertion into a body, may include an elongate member extending from a proximal end to a distal end, where the distal end may be configured to be positioned inside the body. The medical device may also include an imaging device positioned at the distal end. The medical device may further include a plurality of light sources positioned at the distal end, wherein a characteristic of light delivered through a first light source may be controlled independent of the characteristic of light delivered through a second light source.

11. A method of using a medical device, the method comprising:
-
inserting a distal end of the medical device into a body, the medical device extending from the distal end to a proximal end, and including at least an imaging device and a plurality of light sources positioned at the distal end; positioning the distal end proximate a work site within the body; illuminating the work site with the plurality of light sources, wherein each light source illuminates a different region of the work site, and the regions together form an image; activating the imaging device to receive the image of the work site outside the body; automatically adjusting a characteristic of light directed through one of the light sources independent of the characteristic of light directed through another of the light sources based on the received image; and controlling, using a control device having a processor configured to execute instructions, each light source of the plurality of light sources to deliver light based on the received image according to a preset illumination pattern, wherein the control device detects a difference in illumination among the regions and adjusts an intensity of each light source until the differences in illumination among the regions are within a threshold. - View Dependent Claims (12, 13, 14)

15. An endoscope system, comprising:
-
an elongate body extending from a proximal end to a distal end; an imaging device positioned at the distal end, the imaging device being configured to direct an image of a work site proximate the distal end to a viewing device positioned proximate the proximal end; a plurality of light sources positioned at the distal end, the plurality of light sources being configured to illuminate the work site, wherein each light source illuminates a different region of the work site, and the regions together form the image; and an illumination control system configured to automatically vary a characteristic of light directed through one of the light sources independent of the characteristic of light directed through another of the light sources based on the image; wherein the illumination control system comprises a processor configured to execute instructions that automatically control each light source of the plurality of light sources to deliver light based on the image of the work site according to a preset illumination pattern, wherein the illumination control system is configured to detect a difference in illumination among the regions and adjust an intensity of each light source until the differences in illumination among the regions are within a threshold. - View Dependent Claims (16, 17, 18)
