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: A plurality of pixels are arranged two-dimensionally in a matrix and individually include a first photosensitive portion and a second photosensitive portion. A plurality of first wirings connect a plurality of first photosensitive portions to each other for every row. A plurality of second wirings connect a plurality of second photosensitive portions to each other for every column. A first reading unit is arranged to read signal data through at least some of the plurality of first wirings. A second reading unit is arranged to read signal data through at least some of the plurality of second wirings. The first reading unit has a reading pixel setting unit arranged to set, based on signal data read in the first frame, a pixel group for reading signal data in a second frame subsequent to a first frame from the plurality of pixels.

Abstract: An X-ray generation device includes an X-ray tube including an electron gun that generates an electron beam and a target that generates an X-ray by incidence of the electron beam; a power supply portion including a booster that boosts an input voltage from outside to generate a high voltage and an insulating block that seals the booster with an insulating material; and a control unit that performs control to generate the X-ray. The control unit includes a first information processing element that performs at least part of the control using a digital signal at a high potential based on the high voltage. The first information processing element is sealed with the insulating material in the insulating block.

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.
