MEASUREMENT APPARATUS FOR TWO TYPES OF BIOLOGICAL INFORMATION AND COMPUTER-READABLE STORAGE MEDIUM

WIPO Patent Application WO/2019/202937

A1

A measurement apparatus includes: a spectral sensor including, spectral means for dispersing reflected light from a living body or transmitted light that has passed through a living body according to a wavelength, and light receiving means including a plurality of pixels; detection means for detecting sample values indicating light reception results of the plurality of pixels at sampling timings; generation means for generating a biological signal relating to first biological information from sample values of a first pixel of the light receiving means at respective sampling timings; and determining means for determining a cycle of the biological signal. The detection means selects a sampling timing based on a cycle of the biological signal, and detects second biological information based on a sample value of at least one second pixel of the light receiving means at the selected sampling timing.
