1. A virtual image module for generating a virtual image with depth, comprising:
a right collimated light signal generator for generating a right collimated light signal which is directed towards one retina of a viewer;
a left collimated light signal generator for generating a left collimated light signal corresponding to the right collimated light signal which is directed towards the other retina of the viewer;
wherein the right collimated light signal and the left collimated light signal form a binocular pixel of a virtual image with a first depth, the first depth which the viewer perceives is modified by changing a convergence angle between light path extensions of the right collimated light signal and the corresponding left collimated light signal projected into the viewer's eyes based on an interpupillary distance, the first depth corresponds to a depth location of a converging point of light path extensions of the right collimated light signal and the corresponding left collimated light signal;
wherein the virtual image is augmented and superimposed to a real object having a second depth by configuring the converging point in proximity to one portion of the real object,
wherein the first depth and a magnification of the virtual image are altered according to the second depth,
wherein the virtual image module is inclusive in a portable augmented reality device,
wherein the portable augmented reality device comprises a real-time image module, the real-time image module comprises a combiner of the portable augmented reality device.
