Information processing device and information processing method

The present technology relates to an information processing device and an information processing method for enabling continuous measurement of information in a body. The information processing device includes a light emitting unit that emits light of a predetermined wavelength, an imaging unit that captures reflected light from an object, an analysis unit that analyzes an image captured by the imaging unit, a storage unit that stores an analysis result analyzed by the analysis unit, a communication unit that transmits the analysis result stored in the storage unit to another device, and a battery unit that generates and stores power to supply electric power to each unit, and the information processing device is embedded in a body to operate. The light emitting unit emits beams of light of different wavelengths. For example, the light emitting unit emits infrared light and red light, and the analysis unit measures oxygen saturation in blood using a ratio of reflected light of the infrared light to reflected light of the red light. The present technology can be applied to an information processing device that is embedded in a body and acquires information related to physical condition.
