Biological information acquisition device and biological information acquisition method

A biological information acquisition method comprising:

• acquiring a detection value from a non-contact biometric sensor;
• measuring a vital sign of a target person using the detection value;
• acquiring image data indicating an image captured by a camera;
• performing at least one of a state estimation process of estimating a state of the target person, an attribute estimation process of estimating an attribute of the target person, or a personal identification process of identifying the target person by performing image processing on the image captured including the target person;
• and
• setting a parameter in measuring the vital sign in accordance with a result of the image processing,
• wherein the parameter includes a fourth parameter corresponding to a measurement range of the vital sign in the measurement, and the method further comprises setting the fourth parameter in accordance with at least one of a result of the state estimation process, a result of the attribute estimation process, or a result of the personal identification process, and
• wherein the state estimation process includes a process of estimating an expression of the target person,
• the attribute estimation process includes at least one of a process of estimating an age of the target person or a process of estimating a gender of the target person,
• personal identification information corresponding to the target person is acquired by performing the personal identification process, and
• the method comprises setting the fourth parameter in accordance with at least one of the expression, the age, the gender, or the personal identification information.
