Abstract: A line-of-sight detection device capable of achieving further improvement in line-of-sight detection accuracy, achieving low latency, and achieving low power consumption is provided. There is provided a line-of-sight detection device including an imaging element, an illumination unit that illuminates an eyeball with a plurality of beams of illumination light, an optical element that guides respective beams of reflected light in a plurality of directions from the eyeball caused by the plurality of beams of illumination light to a direction of the imaging element, an optical system that causes the imaging element to non-selectively receive the beams of reflected light in the plurality of directions from the eyeball, and a calculation unit that converts, on the basis of the beams of reflected light in the plurality of directions from the eyeball received by the imaging element, the beams of reflected light into information of eyeball movement and/or positional information of a pupil.

Abstract: It is possible to guide a mounting state of a head-mounted image display device to a visually recognizable region that is a correct design position.
A head-mounted image display device 100 includes an image acquisition unit 104 that acquires a positional relationship image from which a positional relationship between a pupil position of an eyeball of a user and a visually recognizable region of the user can be estimated and a projection system 103 onto which incident light is projected, and the visually recognizable region is a focal position of the projection system 103. Further, the image display device 100 includes an imaging element, and the imaging element acquires the three-dimensional positional relationship image.
