  • Patent number: 11172853
    Abstract: A technique restrains degradation of a light emitting element. A biological information acquisition device acquires light receiving result by causing a light receiving unit to receive light emitted by a light emitting unit serving as a measurement-purpose light emitting unit, and acquires biological information by using the light receiving result. The light is emitted from the light emitting unit so as to acquire the light receiving result for one time, while a plurality of light emitting patterns are switched between a light emitting element which emits the light and a light emitting element which does not emit the light in a plurality of the light emitting elements.
