Method for calibrating color curve of medical display

Abstract

The invention discloses a method for calibrating a color curve of a medical display. The method specifically comprises the following steps of establishing an RGB coordinate system, establishing and displaying the relation between color coordinates and RGB, taking a cube with the edge length being N in the RGB coordinate system according to the RGB coordinate system established in the step S1, andsetting the vertex coordinates of the cube; obtaining the color coordinates (X, Y, Z) of each vertex; analyzing a function according to the color coordinates, and predicting the RGB value (R1, G1, B1)of the first point of a target curve; moving the center of the cube to (R1, G1, B1) according to the predicted RGB values (R1, G1, B1), and obtaining the color coordinates of the vertex of the cube again; and SS3, judging whether the color coordinates of the target point are in the cube according to the color coordinates of the vertex of the cube, if not, optimizing and analyzing the function byusing the color coordinates obtained in the step SS4, and performing re-prediction until the target point is contained in the cube. According to the present invention, the color curve precision and the speed of the medical display are improved.

Description

technical field [0001] The invention relates to a method for calibrating the color curve of a medical display, belonging to the technical field of medical display. Background technique [0002] In recent years, computer-based multimedia image processing technology has been widely used in medical imaging and other fields, greatly enriching doctors' diagnostic methods; in order to improve the quality of doctors' reading images and the display capabilities of monitors, the curve requirements for medical monitors are no longer required. For the brightness requirement alone, there are corresponding requirements for chromaticity coordinates for each level of brightness. Even in order to further improve the display capability of the display, there are still differences in the requirements for chromaticity coordinates of each level of the display. [0003] In this regard, the traditional method of separate calibration of color and brightness curves cannot meet the needs of productio...

Problems solved by technology

[0005] The present invention aims at the limitations of the image color curve calibration of traditional medical displays, that is, the calibration of curves and colors separately during calibration results in relatively large final calibration errors, and the relatively long time cannot meet the requirements of the application. It provides a calibration for the color curve of medical displays. method to improve the accuracy and speed of the color curve of the medical display, and further improve the accuracy of the doctor's reading
