Patent ID: 10352850

Abstract:
This calorie measurement device is provided with the following: a light-emission unit that exposes a food article to light that contains near-infrared wavelengths; a light-reception unit that receives transmitted light that had passed through the food article and/or reflected light that was reflected by the food article; a correction unit that computes a base absorbance for the food article on the basis of the transmitted and/or reflected light and corrects the light intensity measured by the light-reception unit and/or the computed base absorbance on the basis of affecting factors, said affecting factors being those that affect the absorption and reflection of light by the food article but are essentially unaffected by the light-absorption and light-reflection properties of the components of the food article; and an analysis unit that computes an analysis value indicating the caloric content of the food article on the basis of the corrected light intensity measured by the light-reception unit and/or the corrected base absorbance.
