Claim 13:
14. The eyeball tracking system of claim 13, wherein
the left tracking camera and the right tracking camera are set to low-exposure cameras when the tracking controller is configured to simultaneously turn on the left infrared light source and the right infrared light source, and track the left infrared light source through the left tracking camera and track the right infrared light source through the right tracking camera to form initial frame tracking images;
the left tracking camera and the right tracking camera are set to high-exposure cameras when the tracking controller is configured to control the left tracking camera and the right tracking camera to correspondingly shoot when the left infrared light source is turned on or the right infrared light source is turned on to form turned-on odd-frame tracking images and turned-on even-frame tracking images,
wherein exposure parameters of the low-exposure cameras are smaller than exposure parameters of the high-exposure cameras.
