Embodiment 1
[0045] figure 2 It is a structural block diagram of a head-mounted display according to an embodiment of the present invention, see figure 2 , the head-mounted display 100 includes: an image acquisition unit 101, an image processing unit 102, a data transmission unit 103, a video decoding unit 104 and a display unit 105:
[0046] An image acquisition unit 101, configured to capture images of the user's head and eyes in real time and send the images of the user's head and eyes to the image processing unit 102;
[0047]The image processing unit 102 is configured to calculate the movement trajectory of the user's eyeballs according to the received images of the user's head and eyes, obtain the key area information of the user's eyeballs currently gazing at the display screen, and send the key area information to the data transmission unit 103;
[0048] The data transmission unit 103 is used to send the key area information to the video output device connected to the head-mount...
Embodiment 2
[0053] image 3 It is a schematic diagram of sub-regions of a frame image according to an embodiment of the present invention. Combined in this example image 3 The shown frame image sub-area structure is schematic, and the decoding and display of the head-mounted display are mainly explained. For other content, refer to other embodiments of the present invention.
[0054] In this embodiment, the images of the user's head and eyes are first collected by the image acquisition unit provided in the head-mounted display. The image acquisition unit here can be a camera, and the camera can be installed in the space between the display screen of the head-mounted display and the user's eyes, and the real-time image can be obtained by capturing the user's head and eyeballs in real time through the camera.
[0055] It should be noted that in the concept of eye movement tracking, there are three main forms of eye movement: fixation, jumping and smooth trailing tracking. According to t...
Embodiment 3
[0067] Figure 4 It is a structural block diagram of a video output device according to an embodiment of the present invention. In this embodiment, the structure and working process of the video output device are mainly explained. For other contents, refer to other embodiments of the present invention.
[0068] see Figure 4 , the video output device 400 includes:
[0069] The communication unit 401 is configured to receive the key area information sent by the head-mounted display that the user's eyes are currently gazing at the display screen, and send the key area information to the video sub-area processing unit 402;
[0070] The video sub-area processing unit 402 is used to divide the current frame image in the video to be output into a high-definition area and a weakened area according to the key area information, and perform no compression encoding or lossless compression encoding on the data in the high-definition area, and perform lossless compression encoding process...
