Embodiment

Please refer to Fig. 1, Fig. 1 is the synoptic diagram of the embodiment of the invention one flow process 10.Flow process 10 is in order to expression one numeric data in a bar code, and it includes following steps:

Step 100: beginning.

Step 102: corresponding to a plurality of numerical value, these a plurality of gray-scale values comprise a maximum reflectivity gray-scale value, a minimum reflectance gray-scale value and differ from least one gray-scale value of this maximum reflectivity gray-scale value and this minimum reflectance gray-scale value with a plurality of gray-scale values.

Step 104: according to the value of this numeric data, by selecting a gray-scale value corresponding to this numeric data in these a plurality of gray-scale values.

Step 106: show this gray-scale value by a component units of this bar code, to represent this numeric data corresponding to this numeric data.

Step 108: finish.

According to flow process 10, in bar code, the present invention sees through other gray-scale value that differs from maximum reflectivity gray-scale value and minimum reflectance gray-scale value in addition and represents other numerical value except representing the numerical value with maximum reflectivity gray-scale value and minimum reflectance gray-scale value.Preferably, the maximum reflectivity gray-scale value is corresponding to white, and the minimum reflectance gray-scale value is then corresponding to black.In other words, except black and white, the present invention sees through in addition and differs from other color black, white dichromatism, as grey, represents other numeric data.In this case, see through the present invention, the data volume that bar code can be put down in writing can significantly promote.What pay special attention to is, the present invention is applicable to one dimension or two-dimensional bar, and is not limited thereto.

For instance, if arbitrary component units of bar code can show three gray levels, white, ash, black, then the present invention can set white corresponding to 0, and grey is corresponding to 1, and black is corresponding to 2.In this case, the pairing color of data [0 1 2] promptly as shown in Figure 2.In Fig. 2, dotted region is represented grey, and mesh-like area is represented black.Therefore, as shown in Figure 2, component units 200,202,204 is display white, grey and black respectively, and the expression value corresponding is 0,1,2.

Except showing that with white, grey, black the present invention also can add error correcting code the numeric data outside raw data, then pairing color of data [012] and the pairing color of error correcting code thereof are promptly as shown in Figure 3.In Fig. 3, component units 300,302,304 is the repetition of component units 200,202,204, component units 306 then be raw data and modulo operation, i.e. (0+1+2) mod (3)=0.Therefore, the pairing data of Fig. 3 are [0 12012 0].

After adding error correcting code, can correct a mistake or detect two mistakes.For instance, if raw data be [0 12012 0], and 0 makeing mistakes and become 1 of centre makes data become [0 12112 0].When decoding,, represent wrong generation because preceding trigram [0 1 2] is different with trigram [1 1 2] thereafter.Next since [0 1 2] and be 0 to meet last sign indicating number [0], and [1 1 2] and be 1 not to be inconsistent last sign indicating number [0], can judge in [1 1 2] first 1 for wrong, thereby can be with the numerical value correction of mistake.Above-mentioned error correcting code is the present invention's one Application Example, and this area tool knows that usually the knowledgeable is when using suitable coded system according to required.
