Endoscope color temperature real-time correction method and device, electronic equipment and camera system

Abstract

The invention discloses an endoscope color temperature real-time correction method and device, electronic equipment and a camera system, and belongs to the field of endoscopes, and the method comprises the steps: obtaining a corresponding relation between a light source control signal and an image color temperature; acquiring a light source control signal, wherein the light source control signal comes from a light source control unit; generating a color temperature correction coefficient by using a corresponding relation between the light source control signal and the image color temperature according to the light source control signal; correcting the color of the real-time shot image according to the color temperature correction coefficient to obtain a picture signal; sending the picture signal to the display, and using the color temperature correction coefficient for processing the real-time shot image so that even if the brightness of the light source changes greatly, the color temperature output by the display can be kept stable, frequent color tone changing of the image is avoided, an operator can see the biological tissue clearly, and popularization and application of the endoscope with the adjustable light source power are facilitated.

Description

technical field [0001] The invention relates to an endoscope color temperature real-time correction method, device, electronic equipment and camera system, belonging to the field of endoscopes. Background technique [0002] In current clinical applications, there is an endoscope that can automatically adjust the power of the light source. While satisfying the imaging brightness, it can prevent biological tissues from being irradiated by high-power light sources for a long time and at close range, and reduce the heat generated by biological tissues during surgery or inspection. Another advantage of this type of endoscope is that since the brightness of the light source can be automatically adjusted, it is not necessary to use the automatic exposure function of the endoscope camera equipment, which eliminates the influence of electronic gain on the image signal-to-noise ratio and improves the image signal. Noise ratio and dynamic range. However, most light sources themselves ...

AI Technical Summary

Problems solved by technology

However, most light sources themselves have the following characteristics. The color temperature of the light source at low power output and high power output often differs greatly. ", but the color of the screen often changes, which can easily affect the operator's identification of biological tissues
