A part of the flexible display forms a curved surface. An intersection of a receiving optical axis of the image capturing device and the curved surface of the flexible display is an intersection point. The two first collimated light sources project two dot-patterns onto the intersection point along two first optical paths having identical length but different extending directions. An included angle between each of the two first optical paths and the receiving optical axis is an acute angle. The two first optical paths and the receiving optical axis are located in a first virtual plane.
