[0046] Such as figure 1 as shown, figure 1 A schematic diagram showing the flow chart of the eye protection method according to the first embodiment of the present invention. Specifically, the eye protection method for a virtual reality head-mounted display device provided in this embodiment includes the following steps:
[0047] Step 100, converting the first pixel represented by the RGB color space of the image of the stereoscopic image into the second pixel represented by the YUV color space, wherein, Y=(0.257·R)+(0.504·G)+(0.098·B )+16; Wherein, Y is the brightness component of the second pixel; R is the red component of the first pixel; G is the green component of the first pixel; B is the blue component of the first pixel;
[0048] Step 200, determine a color vector based on the second pixel; the color vector is used to reduce the blue component B of the first pixel, and increase the red component R of the first pixel and / or the green component G of the first pixel, so...

[0079] The second embodiment is implemented based on the first embodiment. Specifically, the stereoscopic image includes a first image and a second image, there is a parallax between the first image and the second image, and the first image and the second image are used to respectively Projected to the left and right eyes of the user, so that the user can experience the stereoscopic effect of the stereoscopic image. Step 100-step 300 is defined as a blue suppression process, and before step 100, the eye protection method also includes:
[0080] The blue suppression process is performed on only one of the first image and the second image in the same time period.
[0081] Preferably, the eye protection method further includes: alternately performing a blue suppression process on the first image and the second image. Here, the time period for performing the blue suppression process on the first image and the time period for performing the blue suppression process on the second i...

[0083] The third embodiment is realized based on the first embodiment. Specifically, the stereoscopic image includes a first image and a second image, there is a parallax between the first image and the second image, and the first image and the second image are respectively projected into the left and right eyes of the user, so that the user experiences the stereoscopic image three-dimensional effect. Define the step 100-step 300 with the preset blue adjustment coefficient b>0.7 as a weak blue suppression process, and define the step 100-step 300 with a preset blue adjustment coefficient b<0.5 as a strong blue suppression process; eye protection method Also includes:
[0084] The blue-weak suppression process and the blue-high suppression process are alternately performed on the first image or the second image.
[0085] Here, the execution time period of the weak blue suppression process and the execution time period of the strong blue suppression process may be different or...
