RECOGNITION CODE BASED ON COMBINATION OF ELEMENT CELLS AND RECOGNITION CODE SHEET |
摘要 |
Instead of the conventional 2-value bit code string of one-value recording (non-record is 0), the least number of types of elements are used for recording the cell numeral information and zero information and the non-record space is made to be a function code, thereby saving the data space and increasing the integratlon. For this, a unit module is mode to be multinary cell information. Element information is expressed by a plurality of elements E 1 to E n composed of it basic numeral and a positive or negative multiple (induding equi-multiple). An arbitrary element from E 1 to E n and combination of the elements serve as cell numeral information and zero information while a non-element cell (space) B 0 is made to be a function code. A plurality of elements B t to B a and a combined element are made to have an intensity structure of light reflectance by the or concentration and density. |
