Claim 18:
19. The apparatus of claim 14, wherein the processor is configured to:
calculate a multiple regression equation by applying multiple regression analysis to pre-meal/post-meal blood sugar based on the acquired skin image, user's body information, and measurement environment information to obtain the calculated multiple regression equation based on a user behavior pattern, the estimated blood sugar measured based on the acquired skin image, and measurement environment log data;
construct a blood sugar regression equation database that stores blood sugar regression equation data bias-adjusted according to the user's body information and the measurement environment information using the calculated multiple regression equation;
confirm the user's body information through image recognition;
estimate a meal time by analyzing the user behavior pattern and classifies the user's meal state into the pre-meal state or the post-meal state based on the estimated meal time; and
measure the robust blood sugar bias-adjusted according to the measurement environment information using the blood sugar regression equation, which is bias-adjusted according to the user's body information and the measurement environment information, and the acquired skin image.
