摘要：A two-dimensional code pattern includes: a boundary pattern in which each of

pixels in a group are set into a turn-on state or a turn-off state; a rotation detectionpattern in which each pixel belonging to a group in each block is set into the turn-onstate or the turn-off state by a light emitting pattern which can detect a rotational angleupon reading of the block; and an information pattern in which both of each pixelbelonging to a first quadrant region in the block and each pixel belonging to a thirdquadrant region are set into the turn-on state or the turn-off state according to firstinformation data and both of each pixel belonging to a second quadrant region and eachpixel belonging to a fourth quadrant region are set into the turn-on state or the turn-offstate according to second information data.
