1. A biological information acquisition device comprising:
processing circuitry configured to acquire a detection value from a non-contact biometric sensor;
measure a vital sign of a target person using the detection value;
acquire image data indicating an image captured by a camera;
perform 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
set 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,
the processing circuitry sets 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,
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 processing circuitry sets the fourth parameter in accordance with at least one of the expression, the age, the gender, or the personal identification information.
