Abstract: A light detection device detects an incident position of light. The plurality of pixels are arranged two-dimensionally in a matrix and individually have a first photosensitive portion and a second photosensitive portion. The first circuit connects a plurality of first photosensitive portions to each other for every row. The second circuit connects a plurality of second photosensitive portions to each other for every column. The first reading unit reads signal data through the first circuit. The second reading unit reads signal data through the second circuit. The first circuit includes row switches arranged to switch electrical connection and disconnection between first photosensitive portions adjacent to each other in the same row.

Abstract: An object is to simply and easily evaluate differences in behavior of the eyes of subjects. A binocular measurement system 1 includes a photodetector 7 that detects reflected light from the right eye ER and the left eye EL of a subject, and outputs image signal of the reflected light, a feature amount calculating unit 11 that calculates a feature amount corresponding to the right eye ER and a feature amount corresponding to the left eye EL based on the image signal, and a comparison value calculating unit 13 that calculates, based on the two feature amounts, a comparison value obtained by comparing the two feature amounts.

Abstract: An eyeblink measurement system 10 is a measurement apparatus for measuring a subject's eyelid position, and includes a lighting device 1 that irradiates light extending across upper to lower eyelids of the subject's eye region E, and an image measurement device 2 that has an optical axis Ia on a plane for which a plane including an irradiation optical axis La of the light is rotated by a predetermined angle θ around an axis A1 along the light to be irradiated onto the subject, obtains height information based on the position of an optical image of the light in an image imaged, and measures the eyelid position based on the height information.
