Abstract: A wearable device is configured to be worn on a head of a user. The wearable device includes a sensing module and an image forming module. The sensing module is configured to sense an intersection of sight lines of two eyes of the user. The image forming module is coupled with the sensing module. The image forming module is configured to project a pattern onto one of the two eyes of the user, such that the pattern is visually located at a first position at which the intersection of sight lines locates.

Abstract: An image processing method includes the following operations: generate a display image by a display device; obtain an eye focus position by a photographic device; sense a head rotation angle to generate a head movement information by a sensing device; sense a body movement to generate a body movement information by a monitoring device; generate a focus target in the display image according to the eye focus position, generate a reference axis according to the focus target, and generate the display image according to the reference axis, the head movement information and the body movement information by a processing device.
