Image processing system, optical sensor, and learning apparatus

An image processing system comprising:

• an optical sensor comprising:
• an optical member configured to refract light from a subject, the optical member comprising a plurality of transmissive units that have different optical properties, thus forming different refraction patterns of light that passes therethrough;
• and a plurality of image sensors configured to receive light that has passed through the transmissive units and to form captured images in which the subject appears, the plurality of image sensors being provided in correspondence with the transmissive units;
• and
• an information processing apparatus configured to acquire attribute information representing an attribute of the subject by inputting the captured images obtained by the image sensors to a trained learning device that has been trained to determine the attribute of the subject,
• wherein the optical properties of the light projecting units are irregular.

• and
• a plurality of image sensors configured to receive light that has passed through the transmissive units and to form captured images in which the subject appears, the plurality of image sensors being provided in correspondence with the transmissive units, wherein
• the plurality of transmissive units in the optical member comprise a first transmissive unit that is arranged at a center and has a predetermined first converging angle, and second transmissive units that are arranged around the first transmissive unit and have a second converging angle that is greater the first transmissive unit.
