Method and apparatus for measuring robust continuous blood sugar using skin image

An apparatus for measuring robust continuous blood sugar using a skin image, the apparatus comprising:

• an image acquisition module configured to acquire the skin image including multiple skin regions of interest;
• a memory configured to store one or more programs;
• and
• a processor configured to execute the stored one or more programs,
• wherein the processor calculates color data from the multiple skin regions of interest in the acquired skin image,
• classifies a user's meal state into a pre-meal state or a post-meal state through analysis of acquired user information,
• estimates blood sugar by applying the calculated color data to a blood sugar regression linear equation corresponding to the classified user's meal state, and
• weighted averages the estimated blood sugar to measure robust blood sugar.

A non-transitory computer-readable storage medium storing computer-executable instructions which cause, when executed by a processor, the processor to perform a method that includes:

• calculating color data from multiple skin regions of interest in the skin image;
• classifying a user's meal state into a pre-meal state or a post-meal state through analysis of acquired user information;
• estimating blood sugar by applying the calculated color data to a blood sugar regression linear equation corresponding to the classified user's meal state;
• and
• weighted averaging the estimated blood sugar to measure robust blood sugar.
