A measurement apparatus includes: a spectral sensor including a plurality of pixels； a unit configured to generate a biological signal from a light reception result of a predetermined pixel； a unit configured to detect a feature amount of the biological signal； a unit configured to set a measurement condition to the spectral sensor； a unit configured to determine whether or not the measurement condition needs to be changed based on the biological signal； and a unit configured to determine, if the measurement condition needs to be changed, in a first cycle of the biological signal, whether or not the measurement condition can be changed in a period from a timing at which the detection unit has detected the feature amount in the first cycle until an ending time of the first cycle.
