Kinds of data transmission method and apparatus

The present invention discloses a method and apparatus kinds of data transmission, the method comprising: collecting a first terminal of the second image displayed on the display screen by the image acquisition module terminal; the second terminal is the picture file to be transmitted by encoding binary data generated and displayed on the screen of the second terminal, the picture corresponding to the plurality of pixels corresponding to the color gradation binary data; the second terminal decodes the acquired image to obtain binary data, and the binary data obtained by reducing the corresponding document, enabling data transmission between terminals. Embodiment of the present invention without additional communication modules in the terminal, manufacturing cost savings; image by the image acquisition module, avoiding the existing Bluetooth, Wi-Fi caused by transmission of electromagnetic radiation and electromagnetic interference problems, more convenient operation effective.
