Biometric information acquisition device

A biometric information acquisition device comprising:

• a light emitting unit having a first light emitting element that emits red light toward a living body, a second light emitting element that emits infrared light toward the living body, and a third light emitting element that emits green light toward the living body;
• a light receiving unit having a first light receiving element that receives the red light that passed through the living body, a second light receiving element that receives the infrared light that passed through the living body, and a third light receiving element that receives the green light that passed through the living body;
• an acquisition section that obtains first information based on a light amount of the red light received by the first light receiving element, second information based on a light amount of the infrared light received by the second light receiving element, and third information based on a light amount of the green light received by the third light receiving element;
• and
• a drive control section that controls drive and stop of each of the first light emitting element, the second light emitting element, and the third light emitting element, wherein
• the biometric information acquisition device measures first biometric information based on the first information and the second information, and second biometric information based on the third information and
• the drive control section performs at least one of a first process, which stops the light emission of the first light emitting element and the second light emitting element when a measurement period for measuring the first biometric information reaches a first time period T1, and a second process, which stops the light emission of the third light emitting element when the measurement period for measuring the second biometric information reaches a second time period T2.
