Recording device, recording method, and program

A recording method comprising:

• acquiring vital signs through a sensor device having a plurality of electrodes;
• recording a bipolar potential of a main channel which is defined by combining the plurality of electrodes, using the vital signs;
• adding a mark to each waveform plotted based on variation of the bipolar potential over time, at a predetermined position on the time axis;
• and
• first adjusting a position of the mark added to each waveform,
• wherein the first adjusting comprises, based on bipolar potentials of reference channels including electrodes included in the main channel, adjusting the position of the mark added to the bipolar potential of the main channel.

A non-transitory computer-readable recording medium storing a computer program for making a computer to execute a process, the process comprising:

• acquiring vital signs through a sensor device having a plurality of electrodes;
• recording a bipolar potential of a main channel which is defined by combining the plurality of electrodes, using the vital signs;
• adding a mark to each waveform plotted based on variation of the bipolar potential over time, at a predetermined position on the time axis;
• and
• adjusting a position of the mark added to each waveform,
• wherein the adjusting comprising, based on bipolar potentials of reference channels including electrodes included in the main channel, adjusting the position of the mark added to the bipolar potential of the main channel.
