<p>[PROBLEMS] To provide a time-of-flight measuring device for performing a lossless compression processing to reduce the amount of data without loss of information before transferring the data from a signal recorder to a data processor such as a computer. [MEANS FOR SOLVING PROBLEMS] A time-series digital signal recorded by a signal recorder is converted into the plural time-series digital signals by being divided into a bit string including baseline information and a bit string not including the baseline information. First, the compression is applied to the time-series digital signal composed of the bit string not including the baseline information by run-length encoding such as zero-length encoding or switching run-length encoding. Subsequently, static Huffman encoding is separately applied to each of the time-series digital signals to compress the data amount.</p> |
