Embodiment Construction

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0020] figure 1 It is a schematic diagram of the overall structure of an electronic endoscope system with the method of the present invention.

[0021] Such as figure 1 As shown, the electronic endoscope apparatus of this embodiment has an endoscope scope 1 as an observation unit, an endoscope image processing device 2, and a display monitor 4 of the light source device 3.

[0022] in figure 1 In this case, the endoscope body 1 has an elongated insertion portion 5 inserted into a body cavity, and an illumination unit 7 and an imaging unit 8 are built in the tip portion 6 of the insertion portion 5. In the insertion portion 5, there is a light guide cable 9 for transmitting illumination light. The exit end of the light guide cable 9 branches and illuminates according to the number of illumination windows at the front end of the endoscope. The connector 10 at the entra...

Abstract

The invention provides a method and a device for controlling the brightness of an electronic endoscope image area. According to the method, by designing and assembling independent lighting window light regulating mechanisms of a special light guide cable and a light source device, the brightness of the lighting light of the lighting window of an electronic endoscope is respectively adjusted, and thus the purposes of partially adjusting the brightness of a partial area of an electronic endoscope view field is achieved. According to the method provided by the invention, a light source device and an electronic endoscope device for respectively adjusting the lighting brightness of the partial area of the electronic endoscope camera view field are provided.

Description

Technical field [0001] The invention relates to the technical field of medical electronic endoscope imaging and inspection, and is particularly suitable for electronic endoscope light source devices and endoscope sub-regional independent control and adjustment of illumination technology, and electronic endoscope systems adopting this illumination technology. Background technique [0002] The electronic endoscope is one of the indispensable instruments for modern medical examinations. It is directly used to observe the tissue morphology of the human internal organs, which is of great significance for the early diagnosis of cancer. [0003] Modern electronic endoscope systems widely use endoscope devices that irradiate illumination light to obtain an endoscopic image in a body cavity. In this type of endoscope system, a camera is equipped at the tip of the endoscope insertion part, and a light guide cable is used to guide the illumination light from the light source device into the b...
