Embodiment 1

[0044] Embodiment 1 of the present invention provides a method for automatically adjusting the brightness of an endoscope light source. see image 3 , the method for automatically adjusting the brightness of the endoscope light source according to Embodiment 1 of the present invention includes steps S1-S4:

[0045] S1: Obtain the current image brightness value and the current luminous flux output level;

[0046] To obtain the brightness value of the current image, techniques such as average photometry or peak photometry in the prior art may be used to quantify the brightness value of the current frame of image. The current luminous flux output level can be marked according to the level of the current position of the stepping motor, and it is not necessary to quantify the specific value of the current luminous flux.

[0047] S2: Calculate the relative brightness difference according to the current image brightness value and the preset image brightness reference value;

Embodiment 2

[0056] see Figure 5 , Embodiment 2 of the present invention provides an endoscope light source brightness automatic adjustment device. The devices include:

[0057] The current information obtaining unit 501 is used to obtain the current image brightness value and the current luminous flux output level;

[0058] Calculation unit 502, configured to calculate the relative brightness difference according to the current image brightness value and the preset image brightness reference value;

[0059] A query unit 503, configured to search for the corresponding target luminous flux output level in the preset relative luminance difference table according to the current luminous flux output level and the relative brightness difference;

[0060] The adjustment unit 504 is configured to adjust the brightness of the light source of the endoscope to the target luminous flux output level.

[0061] Preferably, the adjustment unit 504 also has the following function: if the relative brig...

Abstract

The invention discloses an endoscope light source brightness automatic adjusting method and device, solving the problems that the imaging environment of an endoscope is not stable and consequently the image brightness flickers. The method comprises the following steps: (S1) obtaining the current image brightness value and current luminous flux output level; (S2) calculating the brightness relative difference according to the current image brightness value and the preset image brightness reference value; (S3) searching for the corresponding target luminous flux output level from the preset brightness relative difference table according to the current luminous flux output level and the brightness relative difference; (S4) adjusting the endoscope light source to the target luminous flux output level. In the invention, the target luminous flux output level is searched from the preset brightness relative difference table, and then the endoscope light source brightness is accurately and automatically adjusted, so that the endoscope system can stably and quickly obtain an image with ideal brightness.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to a method and a device for automatically adjusting the brightness of an endoscope light source. Background technique [0002] During endoscopic surgery, the doctor controls the mirror body to image the cavity, and the imaging environment changes in real time, which will affect the stability of the image brightness. In order to obtain an image with ideal and stable brightness, it is necessary to process the image or adjust the light source. [0003] In the prior art, the brightness of the image display can be adjusted by digital image processing or by adjusting the brightness of the display, but the image obtained in this way is not real, so that the doctor cannot obtain effective lesion information of the operation site to be observed, and the use effect is not good. [0004] In some endoscope products, the method of controlling the luminous power of the light source is used t...
