    Abstract: A pulse wave detection method includes obtaining an image obtained by photographing a subject with an imaging device, extracting intensities representative of signal components of a specific frequency band for respective wavelength components among signals of a plurality of wavelength components included in the image, calculating, using the intensities extracted for the respective wavelength components, a weight coefficient by which a signal is multiplied when the signals are calculated between the wavelength components to minimize an arithmetic value of the signal components in the specific frequency band after multiplication, multiplying at least one of the signals of the respective wavelength components by the weight coefficient, performing arithmetic operation on the signals between the wavelength components after multiplication by the weight coefficient, and detecting pulse waves of the subject using a signal after the arithmetic operation.

    Abstract: A specifying method includes specifying a first period for which it is determined that a specific movement or a specific posture is being performed by applying a first threshold to time series data obtained from a sensor for detecting a movement of a person, specifying a second period for which it is determined that the specific movement or the specific posture is being performed by applying a second threshold to the time series data, the second threshold being eased compared to the first threshold, specifying a transitional period based on a difference between the second period and the first period, the transitional period corresponding to one of a period of a transition to the specific movement or the specific posture, and another period of another transition from the specific movement or the specific posture to another movement or another posture and outputting a result.
