Problems solved by technology

[0006] In addition, in the prior art, medical monitors can only choose to implement DICOM curves or Gamma 2.2 curves on the full screen when presenting images. If the image is a composite image, that is, it has grayscale and color images at the same time. Grayscale standard display function (GSDF, Grayscale standard display function) is defined in DICOMPart14. If the grayscale image is executed with a Gamma 2.2 curve, it will cause the image to be too bright and the details of the dark level will be lost. errors in the diagnosis of the disease
Similarly, if the DICOM curve is implemented for medical color images, the image will be too dark, the color contrast will be reduced, and the color error of the real image will be too large.

Abstract

The invention discloses an automatic Gamma curve setting method of a display. The automatic Gamma curve setting method automatically detects whether an input image is a gray level image or a color image, judges whether the input image is the gray level image or the color image according to the image value so as to classify, and automatically executes the corresponding Gamma curve. Therefore, a diagnosis platform is provided for a user to carry out correct judgment through correct image presentation.

Description

technical field [0001] The invention relates to the technical field of medical displays, in particular to a display for adjusting composite images by using automatic Gamma curve setting and color temperature. Background technique [0002] Generally, medical displays are generally divided into three categories: diagnosis, operating room and teaching. Among them, diagnostic displays often require high resolution and high brightness. Called DICOM) adjustment and other features. The monitors used in the operating room are oriented to front-end imaging equipment such as endoscopes. As surgical auxiliary information display equipment, they need to match the characteristics of the imaging equipment. For example, moderate resolution and average brightness require gamma adjustment. [0003] Users of medical monitors, such as radiologists, often need to view various data of patients at the same time, such as CT / MRI images, medical record data, or surgical images. In addition to comm...
