It is the same as in the first embodiment to display the feature value over the scatter diagram, but when the feature value of the hemoglobin change waveform of the subject A measured by the biological light measurement device 40 is obtained.
- the time data processing unit is the same feature already extracted The feature quantity of the subject is read out, and the past feature quantity is displayed on the scatter diagram together with the newly obtained feature quantity. At this time, an indication that changes with time, for example, an arrow from past data to new data is displayed.
- the operation of the time data processing unit may be automatically performed simultaneously with the processing of new data, but a command to display past data is sent via the input device, or the number of past data to be displayed is determined. It can also be set.
- FIG. 9 shows a display example.
- the past two data and the newly measured data are displayed in the direction of the arrow.
- This embodiment is different from the above-described embodiment in that a one-dimensional scatter diagram is created.
- a one-dimensional scatter diagram is created.
- an inclination value or an integral value is obtained from the hemoglobin change waveform measured by the biological light measurement device 40. Then, according to the calculated value, as shown in Fig. 10, the individual data positions on the one-dimensional scatter diagram are labeled and displayed on the display.
- the boundary between A range and B range is the boundary between typel and type4 in Fig. 9. Therefore, the A range is defined as the range of suspected disease, and the B range is defined as the range of healthy subjects. For example, if it corresponds to the position of the slope value strength range like the feature amount 810, since it is a healthy person, the feature amount 810 is displayed as being within the range of the healthy person. In addition, if the slope value corresponds to the position of the A range as in the feature amount 810, the feature amount 800 is displayed on the one-dimensional scatter diagram because there is a suspicion of the disease.
- the boundary between the C range and D range is the boundary between typel and type2or3 in Fig. 9. Therefore, the C range is defined as the range of suspected disease, and the D range is defined as the range of healthy individuals.
- the slope value is in the C range, such as feature quantity 801 and feature quantity 811. If it corresponds to the position, each feature amount is displayed on the one-dimensional scatter diagram because there is a suspicion of the disease.
- mental disorders may be determined and displayed using two one-dimensional scatter diagrams. If either the slope value or the integral value exceeds the threshold, it is displayed as a healthy person. For example, if the feature quantity 810 and the feature quantity 811 are the same subject's feature quantity, the feature quantity 810 falls within the range B, so it is determined that the person is a healthy person, and the determination result is displayed. If the feature quantity 800 and the feature quantity 801 are the same subject's feature quantity, since both do not exceed the threshold value, it is determined that the patient has a disease, and the determination result is displayed.
- the disease state can be determined based on the position of the feature amount even on the one-dimensional scatter diagram.
- the disease determination support system of the present invention can be applied to any disease other than mental illness as long as it is correlated with a biological light measurement signal. It can be applied even to other diseases.
