An electronic device ( 1 ) includes an imaging unit ( 10 ), and an extraction unit ( 20 ) that is configured to extracts rhythm information indicating a pattern of a spatial change in an image captured by the imaging unit ( 10 ). The extraction unit ( 20 ) includes a first storage unit ( 22 ), a calculation unit ( 24 ), and a selection unit ( 26 ), the first storage unit being storing rhythm information associated with a pattern of a spatial change in a unit region in an image, the calculation unit being calculating a pattern of a spatial change in a unit region in the image captured by the imaging unit ( 10 ), the selection unit being selecting the rhythm information corresponding to the pattern of the spatial change in the unit region calculated by the calculation unit ( 24 ), from the first storage unit ( 22 ). |
