(e) comparing the first pulse wave amplitude information with the second pulse wave amplitude information, and outputting a comparison result indicating a degree of variation in the blood flow of the body,
(f) storing the outputted comparison result in the memory, and
(g) after having performed said operations (a)-(f) at least one time to obtain at least one previous comparison result which is stored in the memory and subsequently performing said operations (a)-(e) an additional time to thereby obtain a new comparison result which is more recently outputted by the at least one processor than the at least one previous comparison result, acquiring a trend in variation of the blood flow of the body between each respective set of the first pulse wave amplitude information and the second pulse wave amplitude information acquired each time operations (a)-(e) are performed, based on the new comparison result and the at least one previous comparison result,
wherein:
a new first video and a new second video are used each time said operations (a)-(e) are performed,
the second video is image-captured after an event is performed by the user at a timing after the timing at which the first video was image-captured, the event being an event performed on an area of the body to increase the blood flow of the body in the area on which the event is performed,
the at least one processor evaluates whether the event has been performed at least twice over a certain period of time, based on a detection at a time of obtaining the new comparison result that the at least one previous comparison result is stored in the memory, and
in response to evaluating that the event has been performed at least twice over the certain period of time, the at least one processor evaluates an effectiveness of the event performed at least twice by the user over the certain period of time based on the trend in variation of the blood flow of the body over the at least two times that the event has been performed.
