<p>PROBLEM TO BE SOLVED: To make proper window judgement by causing a window to follow the change in a pulse rate and pitch, even when the change is substantial. SOLUTION: Regarding a pulse rate measurement device, the upper limit width of a window for the measurement results of the device is first set at +20% for the previously measured value, and the lower limit width of the window is set at -20% for the value. In a subsequent process, when a body motion becomes large, the upper limit width is expanded to +80% for the previously measured value for the first four seconds, and the lower limit width is narrowed to -10%. Subsequently, the upper limit width is narrowed to +60%, +40%, and +20%. Furthermore, when the body motion becomes small, the upper limit width is set at +10% for the previously measured value, and the lower limit width is set at -60% of the value.</p> |
