Problems solved by technology

However, after the light source system has been used for a period of time, the dust attached to the filter or the brightness of the light source lamp attenuation will cause the ratio of the light source to shift, which will affect the display effect of the endoscope system image

Embodiment Construction

[0023] The present invention will be further described below in conjunction with drawings and embodiments.

[0024] A kind of endoscope light source compensation method, such as figure 1 As shown, but before step S1, it also includes the step of setting the brightness level, that is, setting different brightness values ​​in different levels according to their magnitude. A brightness level may be a range of brightness values. In this embodiment, it is implemented by setting a brightness level table, and the brightness level table may be as shown in Table 1.

[0025] Table 1 Brightness level table

[0026] brightness level Brightness value range 1 2-10 2 10-20 …… …… M 90-100

[0027] Specifically, the endoscope light source compensation method of the present invention includes the following steps:

[0028] S1: Initialize the brightness level. In this embodiment, after the brightness level is initialized, the brightness level of the light s...

Abstract

The invention discloses an endoscope light source compensation method and an endoscope system. The endoscope light source compensation method comprises the following steps of: S3, obtaining the brightness value of an NXth frame of picture, wherein X is a non-zero natural number; S4, judging whether the brightness value of the NXth frame of picture is within the current brightness level range or not, if the brightness value of the NXth frame of picture is within the current brightness level range, entering a step S5, otherwise, adjusting a potentiometer, and returning to the step S3 after X plus 1; and S5, judging whether the current brightness level reaches a maximum brightness level or not, if the current brightness level reaches the maximum brightness level, ending, otherwise, adding 1 to the brightness level, and returning to the step S3. The problem that an image effect becomes poor due to the fact that the light distribution brightness changes after the light source is used for a long time can be effectively solved, the endoscope light source compensation method is not only suitable for the field of endoscopes, but also suitable for other image collection fields, the brightness of the light source is adjusted safely, reliably, effectively, easily and conveniently through an automatic compensation scheme until the brightness of the light source achieves a preset matching state, and therefore a purpose of compensation is realized.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to an endoscope light source compensation method and an endoscope system. Background technique [0002] The endoscope includes an image processing system, a light source system, a mirror body, a display and a trolley, etc. The light source system is an important part, providing light source for the whole system to collect images. In order to display the details of blood vessels or lesions in the gastrointestinal tract, the light source system generally uses two-color or multi-color light sources, and will be combined into the light source used by the mirror body according to a certain ratio. The light source system of the endoscope is loaded at the factory to present the best image effect. The ratio parameters of each color light source. However, after the light source system has been used for a period of time, dust will adhere to the filter or the brightness of the light sourc...
