1. An apparatus for measuring a biological component, the apparatus comprising:
- a spectrum data acquirer configured to acquire spectrum data of a user by emitting light to a skin of the user and detecting the light that is reflected from the skin; and
a processor configured to;
extract a user characteristic signal from the acquired spectrum data by subtracting, from the acquired spectrum data, a background signal and a first unit component spectrum, the background signal being spectrum data that is measured at a predetermined time interval in a reference state in which a change does not occur in the biological component, and the first unit component spectrum being a predetermined unit of spectrum of the biological component; and
obtain a second unit component spectrum that is personalized to the user by updating the first unit component spectrum based on the extracted user characteristic signal.

Abstract
An apparatus and method for measuring a biological component are provided. The apparatus may include a spectrum data acquirer configured to acquire spectrum data of a user by emitting light to a skin of the user and detecting the light reflected from the skin, and a processor configured to extract a user characteristic signal from the acquired spectrum data using a background signal and a first unit component spectrum and generate a second unit component spectrum personalized to the user by updating the first unit component spectrum based on the user characteristic signal.
