263<p>
264Object data items are stored in the obj[] array in the order that they are detected by the pointer. The pointer scans the image captured by sensor internally from top left to bottom right and outputs object data in the order detected. At the same time, trace ID(s) are assigned in the order that the objects are detected.
265</p>
266<p>
267The trace ID helps to judge whether previously obtained data is the same as the currently obtained data. Consider a case where objects A (trace ID=0) and B (trace ID=1) are detected as A and B, respectively, by the previous scan, and then they are detected as B and A, respectively, after the pointer is moved. The output order for the current scan is the reverse of the previous one. However, the trace IDs are in the order of B (using the previously assigned trace ID of 1) and A (using the previously assigned trace ID of 0), and the fact that the data is the same is preserved.
