1. A reading method for a two-dimensional code, comprising:
capturing a two-dimensional code image by using an image capturing device, wherein the two-dimensional code image presents a two-dimensional code in a skewed state;
detecting an outer frame and a position mark of the two-dimensional code in the skewed state in the two-dimensional code image;
restoring the two-dimensional code in the skewed state to a default state in accordance with the outer frame and the position mark; and
performing a default operation in accordance with the two-dimensional code in the default state.
