EYEBALL TRACKING DEVICE AND AUXILIARY LIGHT SOURCE CONTROL METHOD AND RELATED DEVICE THEREOF

摘要

An eyeball tracking device (100), comprising: a processor (110), an infrared camera (130) and an auxiliary light source (150); the processor (110) is electrically connected with the infrared camera (130) and the auxiliary light source (150); the infrared camera (150) is used to output a frame sync signal; the processor (110) is used to receive the frame sync signal; the auxiliary light source (150) is controlled, according to the frame sync signal, to continuously output infrared auxiliary light in a preset period of time; the infrared camera (130) is controlled to expose in the preset period of time; the duration of the preset period of time is shorter than the frame period, which is the cycle period of the frame sync signal. An auxiliary light source (150) control method and a control device (300) for the eyeball tracking device (100) and a non-volatile computer-readable storage medium storing one or more programs. The eyeball tracking device (100) has the advantages of low power consumption, and can effectively improve the image quality of an eyeball image.
