ABSTRACT:
A device for measuring a retina reflected light amount is provided with a light source for emitting a infrared ray, an image pick-up unit for receiving the infrared ray from a light emitting range at the same position as the light source, a reading unit for reading a pupil area from a face image picked up by the image pick-up unit, and an integrating unit for integrating an amount of light represented by signals which are generated by the image pick-up unit and are located at addresses within the read pupil area. This device is applicable to a gaze detecting apparatus, and provides data which can be used in medical and psychological fields.
