In the embodiment of the present invention, in order to clearly show the focus of the invention, the grid lines and the marked data positions are explained. In the actual use situation, there is no grid line. In addition, only the data indicators will appear, and the data position will not appear.

Referring to FIGS. 1A and 1B, FIG. 1A shows an image index according to a first embodiment of the present invention, which is formed on a recording medium (for example, paper), and corresponds to an index data, and FIG. 1B shows a plurality of images. The image index of the embodiment of Fig. 1A is formed on the recording medium. The image index includes a content data portion 10, a head portion 20, and a pointing data portion 30. The content data section 10 includes a plurality of content material units 11, each of which includes a content data record. The number 111 and the plurality of virtual content data locations 112, in each of the content material units 11, the content data tokens 111 are selectively located in one of the virtual content data locations 112 (eg, the content data tokens in FIG. 1A) 111 marked). The table header 20 includes a plurality of header units 21, each header unit 21 includes a header symbol 211 and a virtual header location 212, 211 in each header unit, the header symbol is located in the virtual table Head position 212. The pointing data unit 30 includes at least one pointing data unit 31. The pointing data unit 31 includes a pointing data symbol 311 and a plurality of virtual pointing data locations 312. The pointing data unit 31 is selectively located in the pointing data unit 31. The virtual points are directed to one of the data locations 312. When the content data unit 11, the header unit 21, and the pointing data unit 31 overlap each other, the virtual content data locations 112, the virtual header locations 212, and the virtual pointing data locations 312 do not overlap each other.

The pointing data section 30 is used to carry data and is used to define the direction of the image index (2D code) to avoid a pattern similar to the head 20 in the horizontal direction. Compared with the conventional technique, the pointing data section 30 of the first embodiment provides the direction of the image index (2D code) while providing the direction of the image index (2D code) in the header area. The three virtual points point to changes in the data location, thus providing more groups of image metric changes.

In the first embodiment described above, when the pointing data unit 31 is located in a first orientation (for example, the orientation shown in FIG. 1A) and the other is in a second orientation (for example, the 180A is rotated by 180 degrees). When the pointing data unit 31 points to the data unit 31, the virtual objects of the pointing data unit 31 located in the first orientation The pointing data location 312 does not overlap the virtual pointing data locations 312 of the pointing data unit 31 located in the second orientation, the first orientation being not equal to the second orientation. From another perspective, the virtual pointing data locations 312 are arranged in an asymmetrical manner on both sides. Thereby, the direction of the image index (2D code) can be defined by pointing to the data unit 31 one by one.

And arranged in a substantially trapezoidal manner, similar to the first embodiment, the virtual pointing data positions 312 of the second embodiment are arranged in an asymmetrical manner on both sides. Thereby, the direction of the image index (2D code) can be defined by pointing to the data unit 31 one by one.

In the first and second embodiments described above, since the virtual pointing data locations 312 are arranged in an asymmetrical manner on both sides, the pointing data unit 31 can provide a function of defining directions and carrying data at the same time.
