Embodiment 1

[0043] like Figures 1 to 3As shown, this embodiment provides a blue light protection device based on a medical display, including: an image generation module, a spectroradiance meter module, an upper computer application software module and a color space conversion module, and the upper computer application software module is respectively connected with The image generation module, the spectroradiance meter module, and the color space conversion module are connected; the image generation module is used to provide the medical display with a test image whose image clarity reaches the pixel level; the spectroradiance meter module is used to measure the medical display Spectral data of red, green and blue primary colors and distribution data of RGB and LAB color spaces; the upper computer application software module calculates in real time the conditions of different color temperatures of the medical display from the RGB color space to the LAB color space according to the data mea...

Embodiment 2

[0065] Such as Figures 4 to 6 As shown, this embodiment provides a blue light protection method based on a medical display, which specifically includes the following steps:

[0066] S1, the image generation module generates test images that meet the pixel level requirements of medical displays with different resolutions and specifications according to the control instructions sent by the upper computer application software module, performs maintenance filtering on the test images, and displays the test images on the medical display panel;

[0067] S2, measure the red, green and blue trichromatic spectral data and the RGB and LAB color space distribution data on the medical display panel through the spectroradiometer module, and send the measurement data to the upper computer application software module;

[0068] S3, the upper computer application software module calculates the conversion mapping table of the medical display from the RGB color space to the LAB color space unde...

Abstract

The invention discloses a blue light protection device and method based on a medical display. The blue light protection device comprises an image generation module, a spectroradiometer module, an upper computer application software module and a color space conversion module, the image generation module provides a test image of which the image definition reaches a pixel level for the medical display; red, green and blue three-primary-color spectral data and RGB and LAB color space distribution data of the medical display are measured through the spectroradiometer module; a conversion mapping table of the medical display from the RGB color space to the LAB color space under different color temperature conditions is calculated in real time through the upper computer application software module; and the conversion mapping table is loaded through a color space conversion module, the normal video stream data of the medical display is converted from the RGB color space to the LAB color spaceunder different color temperature conditions, and the converted data is output . By rapidly and accurately adjusting the color temperature, the blue light component of the pixel-level image of the medical display is effectively reduced, and then the blue light harm of the medical display is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical display, in particular to a blue light protection device and method based on a medical display. Background technique [0002] In recent years, the digitalization process of medical imaging has accelerated: on the one hand, imaging systems such as CT, MRI, ultrasound (us), and digital radiography have been directly digitized; The network of the information system (Hospital Information System, HIS) is connected in parallel to form the medical image storage and transmission system (Picture Archiving and Communication System, PACS). These advanced technologies make "soft film reading" possible. As a display terminal, medical displays have become an important visualization device for doctors to perform medical imaging diagnosis. [0003] The luminescence of medical display screens is generally in the visible light range of 380-780nm, and the color display generally obtains color images through red, g...
