Embodiment

[0029] Example: such as Figure 2-3 As shown, it is an embodiment of an adaptive correction method for a display color grayscale image of the present invention. Aiming at problems such as brighter or color cast images caused by a single correction method, the image features are analyzed according to the image content, and the image features are adaptively corrected. Identify color and grayscale image content, and adopt different correction methods for different content. Such as figure 2 As shown, a high-resolution display includes a color image area 1 , a grayscale image area 2 , and a mixed color and grayscale image area 3 . Therefore, the GAMMA correction method is used for the color surgical video in the color image area 1, and the CT and MRI images in the gray-scale image area 2 are corrected by DICOM, and the left half of the mixed image area 3 is a gray-scale image. But there are some color characters used for information description; the right half is a color image, ...

Abstract

The invention discloses an adaptive correction method for a color gray-scale image of a display. The adaptive correction method comprises the following steps of: detecting and counting color gray-scale characteristic points; determining a color gray-scale region; and adopting different correction methods according to different image attributes. The color and gray-scale contents in the image can be adaptively recognized, and different correction methods are adopted for different contents. According to the adaptive correction method, the display function of color and gray-scale images is integrated in a color display of high resolution, so that the image display quality is guaranteed, the space occupied by equipment is reduced, and inconvenience brought by complex signal switching and independent control is avoided.

Description

technical field [0001] The invention relates to a method for self-adaptive correction of a display color gray scale image. Background technique [0002] Generally, medical displays are generally divided into three categories: diagnostic use, operating room use and teaching use. Among them, diagnostic displays often require features such as high resolution, high brightness, and DICOM (Digital Imaging and Communications in Medicine) correction; and operating room displays are oriented to front-end imaging equipment such as endoscopes, and as surgical auxiliary information display equipment needs In line with the characteristics of imaging equipment, moderate resolution and average brightness require GAMMA correction [1]. Users of medical displays, such as doctors in the radiology department, often need to view various data of patients at the same time, such as CT / MRI images, medical record information, and surgical videos. In addition to common gray-scale images, many image ...
