Apparatus and method for estimating component of analyte

A method of estimating a component of an analyte, the method comprising:

• operating a sensor under preset initial operating conditions;
• detecting an initial amount of received light from the analyte under the initial operating conditions;
• determining optimal operating conditions based on the initial amount of received light and the initial operating conditions;
• measuring a spectrum from the analyte by operating the sensor under the optimal operating conditions;
• and
• estimating the component of the analyte based on the spectrum,
• wherein the obtaining of the component of the analyte comprises obtaining a reference spectrum, obtaining an absorption spectrum of the analyte based on the spectrum and the reference spectrum, and estimating the component of the analyte based on the absorption spectrum.

An electronic device comprising:

• a main body;
• a memory disposed in the main body;
• and
• a processor disposed in the main body and electrically connected to the memory,
• wherein the processor is configured to:
• operate a sensor device under initial operating conditions stored in the memory based on a request for estimating an antioxidant index being received,
• adjust, based on an initial amount of received light being obtained from skin of a user, at least one of a light exposure time and a light source current among operating conditions of the sensor device based on the initial amount of received light,
• obtain a spectrum from skin of the user by operating the sensor device under adjusted operating conditions, and
• estimate the antioxidant index based on the spectrum wherein the processor is further configured to adjust the light exposure time based on a ratio of the initial amount of received light to a preset optimal amount of received light and the light exposure time of the initial operating conditions.

An apparatus for estimating a component of an analyte, the apparatus comprising:

• a sensor including a light source configured to emit light to the analyte, and a detector configured to measure a spectrum of light reflected from the analyte;
• and
• a processor configured to:
• based on an initial amount of received light being obtained from the analyte by operating the sensor under first operating conditions, determine second operating conditions based on the initial amount of received light and the first operating conditions;
• based on a spectrum being measured from the analyte by operating the sensor under the second operating conditions, estimate the component of the analyte based on the spectrum, and
• obtain an absorption spectrum of the analyte based on the spectrum and a reference spectrum.
