Abstract: An ophthalmic image of an evaluation target is acquired, a plurality of subsection images is extracted from the ophthalmic image, a state of a subject's eye is predicted for each of the subsection images based on a learned model in which learning has been performed in advance regarding extracting a plurality of subsection images from an ophthalmic image for learning, and predicting a state of a subject's eye for the each of subsection image by machine learning using correct answer data related to a state of each subsection image, and the subsection image is extracted from the ophthalmic image so as to have an image size corresponding to a state of a subject's eye of an evaluation target.

Abstract: An object of the present invention is to provide a technique that can improve the measurement accuracy of the blood component concentration. A blood component measurement system emits light to a measurement site of a living body while the measurement site is compressed, and calculates a concentration of a predetermined blood component based on a pulse wave signal acquired based on light received from the measurement site. A blood component measurement system includes a processing unit that performs a process of analyzing the pulse wave signal and determining a pressure condition of the measurement site; and a calculation unit that calculates a concentration of the blood component using the pulse wave signal in a period in which the pressure condition is determined.
