1. A head-mounted display device, comprising:
a frame;
a track, disposed on a peripheral region of the frame;
a sensor, disposed on the track, is configured to capture a target image of a target area;
an actuator, disposed on the track and connected to the sensor; and
a controller, coupled to the sensor, is configured to generate, after the target image is captured, a control signal according to an area of an eyeball image in the target image,
wherein the actuator moves the sensor on the track according to the control signal to adjust a position of the sensor on the peripheral region
wherein when the sensor moves on the track, the position of the sensor and a view angle for capturing the target area are changed correspondingly, and a fixed relationship between the position and the view angle of the sensor is pre-established as lookup information and provided to the controller,
wherein the controller is configured to obtain the view angle of the sensor according to the position of the sensor.
