<p>The present invention provides a system and a method which can transmit data in an environment where radio frequency (RF) communication is disabled. A system for transmitting data using an image code comprises: a code generating device (110) which selects one of colors represented on the display device and generates a series of brightness values corresponding to inputted source data according to a number (m) of brightness value intervals for the selected color; a display device (120) which outputs a series of brightness values according to a number (k) of split areas of a screen according to a reference order; and a code decoding device (130) which acquires the series of brightness values outputted on the display device using a camera and decodes the series of brightness values into source data.</p> |
