Abstract

A method, an apparatus, and a terminal for recognizing a two-dimensional code are provided. The two-dimensional code includes an image region and an encoding region. The image region and the encoding region have no overlap. The method includes selecting, from pixels of the two-dimensional code, a pixel included in a code element in an encoding region. The method further includes determining a value of the code element in the encoding region according to the pixel included in the code element in the encoding region. The method further includes recognizing the two-dimensional code according to the value of the code element in the encoding region.
