Problems solved by technology

Therefore, excessive blue light content may cause increased visual fatigue
[0006] 2. It may affect the physiological development of the eye
[0008] 4. Blue light will increase the amount of toxins in the macular area of ​​the eye
[0009] 5. If you work in such a light environment for a long time, the possibility of inducing macular degeneration in the human eye will increase when you are old.
However, the disadvantage of the existing technology is that the solution to eliminate short-wave blue light in different display environments is not universal, and different technical solutions need to be given for different display environments.

Embodiment Construction

[0048] The inventor noticed during the invention that:

[0049] Computers, mobile phones, and virtual reality displays that have appeared in recent years all contain this short-wave blue light. For the VR (Virtual Reality, virtual reality) system, its characteristic is that the display screen is very close to the human eyes, about 4-7 cm, which has a great impact on the eyes. Especially in VR helmets, the surroundings of the eyes are in a dark environment, the pupils are opened larger, and the amount of light passing through is more, so it is necessary to find ways to reduce the impact of blue light on the eyes.

[0050] Since the red, green, and blue colors can be mixed to produce various colors in nature during display, the light emitted by the display screen contains blue. Blu-ray is indispensable, it cannot be eliminated, it can only be reduced. And it can only be reduced to a certain extent, so as not to display color distortion and seriously affect the display effect. ...

Abstract

The invention discloses a display method and device for reducing blue light of an image. The method comprises that the image to be displayed is obtained; the color value of each pixel in each frame of image is obtained; the sum of blue components in the color values of the pixels and the total pixel amount are determined; and when the proportion of the sum of the blue components to the total pixel amount is greater than a preset threshold, blue pixels in the image are reduced, and then the frame of image is displayed. According to the display method and device, the amount of the blue light in a virtual reality (VR) image can be adjusted, influence of blue light on the vision is reduced, adjustment of blue light is dynamic, and change of the VR image can be corrected in real time with adjustment of ratio of blue in the image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a display method and device for reducing blue light of images. Background technique [0002] The light in nature is composed of various spectrums of different colors. Different wavelengths visually present different colors. Blue light is light with a wavelength between 400 and 500 nanometers. It has short wavelength, high energy, and penetrating power. powerful. [0003] Gary Heiting, senior editor of AllAboutVision.com, believes, "No one is sure whether long-term use of digital devices will cause permanent damage to the eyes, but what is certain is that it will definitely cause eye fatigue and discomfort." After prolonged use of smartphones or computers, symptoms such as dry eyes, blurred vision, and visual fatigue will appear. According to a recent report released by the Vision Council in 2015, about 60% of Americans experience symptoms of eye fatigue after long-term...
