Abstract: [Problem] To predict a remaining time during which a fluorescence image is observable. [Solution] An information processing device according to the present disclosure includes a remaining time estimation unit that estimates, on the basis of a luminance limit value for observation of a fluorescence image and a change in luminance of a fluorescence image, a remaining time until the luminance of the fluorescence image reaches the luminance limit value. This configuration enables the time at which the luminance of a fluorescence image reaches the luminance limit value to be estimated according to a change in luminance of the fluorescence image, and it is possible to predict a remaining time during which a fluorescence image is observable.

Abstract: A method and device for distinguishing between yeast infection and other secretion-causing conditions makes use of the observation that secretions caused by yeast infection generally have a pH of less than about 4.5, whereas most other conditions cause less acid secretions. The device is for use by the woman having the secretions and does not involve introducing anything into the body nor does it require special skills or training. A material that indicates pH by a color change is mounted on a catamenial pad, pantyliner or the like worn on the body so as to be wetted by the secretions draining from the vagina. Observation of the color of the wetted material enables the user, by simple comparison to a color chart, to determine whether she has a yeast infection that is treatable by medicine available without medical prescription or whether she should instead see a physician because yeast treatment would be ineffectual and would delay proper treatment.
