Systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

A light guide plate according to one or more embodiments may include a plurality of optical path deflectors arranged in a matrix. Each of the plurality of optical path deflectors may include a plurality of optical path deflector sets. The plurality of optical path deflectors may include a first cell and a second cell located periodically. The first cell may include a first deflector that deflects light within a first angle range. The first cell may be free of a second deflector that deflects light within a second angle range adjacent to the first angle range. The second cell may be free of the first deflector and may include the second deflector.

A stereoscopic display device including a display panel and an optical element is provided. The optical element is disposed on a display surface of the display panel. The optical element includes a lenticular lens array. The lenticular lens array includes a plurality of lenticular lenses extending in a first direction. The lenticular lenses are arranged in a second direction. The optical element includes a center line extending in the first direction. The lenticular lenses include a first lenticular lens and a second lenticular lens. The distance between the first lenticular lens and the center line is smaller than the distance between the second lenticular lens and the center line, and the curvature of the first lenticular lens is greater than the curvature of the second lenticular lens.

A head-up display system for a vehicle includes a head-up display apparatus and an occupant monitoring apparatus. The head-up display apparatus includes a projection device configured to project a three-dimensional image in front of an occupant of the vehicle. The head-up display apparatus is configured to project a projection image with respect to an object present outside of the vehicle. The occupant monitoring apparatus includes an imaging device configured to capture an image of the occupant. The occupant monitoring apparatus is configured to generate personal data related to a sense of sight of the occupant on the basis of the captured image of the occupant. The head-up display apparatus is configured to adjust the projection image in the three-dimensional image on the basis of the personal data generated by the occupant monitoring apparatus, and project, from the projection device, the three-dimensional image in which the projection image is adjusted.

An image display device acquires positional information including a distance between at least one eye of an observer and an image display surface, and corrects, based on the acquired positional information, a relative positional relationship between slit areas and an image displayed on the image display surface, by using a width smaller than the width of one subpixel as a minimum correction unit.

Provided are stereoscopic eyeglasses capable of reducing visual fatigue in binocular stereoscopic display by a simple configuration. In stereoscopic eyeglasses, in order to expand a tolerance of match between vergence and accommodation enabling comfortable stereovision in eyeglasses-using stereoscopic display, wide-focus lenses ranging in focal length are incorporated so as to overlap optical filters in light transmission directions, and accordingly, visual fatigue to be caused by vergence-accommodation conflict during stereoscopic image observation is reduced.
