摘要：

PROBLEM TO BE SOLVED: To provide a biological information measuring apparatus capable of suppressing the saturation of the output of a light receiving element, then, accurately measuring biological information such as pulses, and a control method therefor.

SOLUTION: The biological information measuring apparatus is equipped with: a light emitting element 21 for emitting light at a prescribed light emitting frequency to the detection region of an organism the light receiving element 22 capable of receiving the emitted light through the organism and receiving external light in linkage with the body motion of the organism and generating light receiving signals on the basis of a light receiving quantity changed according to the pulsation and body motion of the organism a liquid crystal filter 31 disposed on the light receiving part side of the light receiving element 22 and capable of freely varying the transmission quantity of the light to the light receiving part a light transmission quantity control part for controlling the light transmission quantity of the liquid crystal filter 31 and suppressing the light receiving quantity of the light receiving element 22 to a saturation level or below and a biological information specifying part for specifying body motion components and pulsation components on the basis of the signal components of a first frequency range including the light emitting frequency and the signal components of a second frequency range lower than the first frequency range in the light receiving signals.
