Image color correction method, apparatus and storage medium suitable for endoscope

Abstract

The invention discloses an image color correction method, device and storage medium suitable for an endoscope. The method includes the steps of: acquiring a grayscale image of a current frame image collected in real time by a camera head of the endoscope; calculating the grayscale The ratio of the first type of pixel in the figure; wherein, the first type of pixel is a pixel whose grayscale value is greater than or equal to the grayscale threshold; judge whether the ratio is greater than or equal to the preset ratio, and if so, use the preset The white balance adjustment algorithm of the described current frame image is carried out white balance process, obtains the current frame image after the color correction, if not, then according to the color correction parameter of the camera head of described endoscope to the color of described current frame image Correction to obtain the current frame image after color correction. The invention can correct the color of the image collected by the endoscope in real time during the use of the endoscope, so that the color of the image is close to the real color, thereby reducing the color cast of the image.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an image color correction method, device and storage medium suitable for endoscopes. Background technique [0002] Endoscope is a commonly used medical device, which integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics and software. With the continuous advancement of medical technology, the clinical demand for endoscope applications will further expand and deepen, and it will become an indispensable device in the diagnosis and treatment of diseases. Due to the limitations of the illumination conditions of the endoscope's own light source and the complexity of the internal environment of the human body, the images collected by the endoscope will be dark in large areas due to insufficient exposure. During the operation, the doctor cannot observe the operating space normally, which will lead to diagnosis Errors and even surgery fai...

Problems solved by technology

Due to the limitation of the illumination conditions of the endoscope's own light source and the complexity of the internal environment structure of the human body, the images collected by the endoscope will be dark in large areas due to insufficient exposure. During the operation, the doctor cannot observe the operating space normally, which will lead to diagnosis. Errors and even surgical failures

In addition, during the process of heat treatment of the lesion while using the endoscope, the treatment light will cause a large color deviation in the image collected by the endoscope, which is very important for the observation of the patient's condition during the operation and the evaluation of the lesion treatment after the operation. cause greater impact
