PROBLEM TO BE SOLVED: To provide an HLC (high dimensional local autocorrelation) feature quantity extracting method and a feature quantity extracting device, by binarizing one-dimensional signal, based on binary HLAC which is suitable for hardware, with which high speed processing can be performed. SOLUTION: The one-dimensional signal is binarized by pulse width modulation (PWM), and the HLAC feature quantity is calculated by applying one dimensional binary HLAC to the one-dimensional binary signal. Each amplitude value of the one-dimensional signal is binarized by any one of linear quantization,μ-Law quantization or gray code quantization, and two-dimensional binary HLAC is applied to a binary image which is generated as its time sequence.
