Analysis apparatus
First Claim
1. An analysis apparatus capable of analyzing a component contained in an analyzed subject or calories of the analyzed subject, the analysis apparatus comprising:
- a light emitter that emits light;
a spectral unit that is configured to disperse first reflection light reflected from the analyzed subject or first transmission light transmitted through the analyzed subject when the light emitter irradiates the analyzed subject with light;
a light detector that detects the first reflection light or the first transmission light dispersed by the spectral unit and generates first detection data that is a voltage value corresponding to an amount of received light, wherein, when the light emitter irradiates an analysis sample with light, in which the analysis sample includes a known component or has known calories, the light detector detects second reflection light, which is reflected from the analysis sample and dispersed by the spectral unit, or second transmission light, which is transmitted through the analysis sample and is dispersed by the spectral unit, and generates second detection data that is a voltage value corresponding to an amount of received light;
a memory that stores a regression equation calculated directly using the second detection data as a parameter; and
an analyzer that estimates the component contained in the analyzed subject or the calories of the analyzed subject directly using the first detection data and the regression equation stored in the memory.

Abstract
An analysis apparatus is provided with: a light emitting part, a light dispersing part, a light detecting part, a storage unit, and a control unit. The light dispersing part disperses first reflected light reflected from a food product when the food product has been irradiated with light from the light emitting part. The light detecting part: generates first detection data by detecting the first reflected light dispersed; and, when a food product sample containing known ingredients is irradiated with light from the light emitting part, generates second detection data by detecting second reflected light reflected from the food product sample and dispersed by the light dispersing part. The storage unit stores a regression formula computed using the second detection data as a parameter. The control unit estimates the ingredients contained in the food product using the first detection data and the regression formula stored in the storage unit.
