Patent number: 10512426Abstract: A storage unit stores a cumulative light emitting frequency or a cumulative light emitting time of a light emitting element. In a case where the cumulative light emitting frequency is greater than a predetermined light emitting frequency or the cumulative light emitting time is longer than a predetermined light emitting time, a control unit causes the light emitting element to emit light toward a living body by increasing the light emitting frequency or the light emitting time at which the light emitting element emits the light in order to acquire a light receiving result once, compared to a setting light emitting frequency or a setting light emitting time. A light receiving unit acquires information of the living body, based on a light receiving result obtained by receiving the light which is emitted toward the living body and transmitted through the living body.Type: GrantFiled: July 27, 2017Date of Patent: December 24, 2019Assignee: Seiko Epson CorporationInventor: Takashi Toya
