To assist work of checking information by a user when biological information is displayed in a relatively small display area of a portable information terminal. A portable information terminal receives sensor signals corresponding to biological information of a subject from sensors attached to the subject. Waveforms indicating variations with time in biological information of the subject are displayed on a display based on the sensor signals. When a user interface receives a given operation, part of the waveform displayed on the display is designated and a trimmed image of the part of the waveform is displayed on the display.
