An automatic measurement point correction method includes acquiring vital signs information waveform data indicating a vital signs information waveform having a plurality of waveforms which periodically appear on a time axis, determining a plurality of measurement points for measuring a predetermined measurement item of each waveform included in the vital signs information waveform, causing the vital signs information waveform and measurement point displayers to be displayed on a displaying section, correcting a first measurement point for measuring the predetermined measurement item of a first waveform of the plurality of waveforms, as a first correction, recording the corrected first measurement point as a reference measurement point, extracting a waveform which is analogous to the first waveform, from the plurality of waveforms, and automatically correcting a measurement point for measuring the predetermined measurement item of the extracted waveform, as a second correction.
