摘要： A system and method for generating compact light-field displays through varying optical depths provides digital content in a more effective and efficient manner. The system includes a field-evolving cavity with a cavity exit pupil, a relay mechanism, and a system enclosure with an enclosure exit pupil. The field-evolving cavity modifies the light-field displays before outputting the light-field displays with the cavity exit pupil. More specifically, the field-evolving cavity includes at least one display panel, which initially generates the light-field displays, and at least one optical-tuning mechanism, which subsequently modifies the light-field displays to varying optical depths. The system enclosure houses the field-evolving cavity and the relay mechanism. The relay mechanism directs the light-field displays from the cavity exit pupil to the enclosure exit pupil, which outputs the light-field displays to a user.

摘要： The image display device includes an image generating unit that emits first image light, a pupil expanding element that expands a diameter of a light flux included in the first image light from the image generating unit to obtain second image light, a first light condensing optical system that condenses the second image light and forms an intermediate image, and a second light condensing optical system that condenses light from the intermediate image and generates a virtual image on eye of a viewer, in a plane including at least the image generating unit, the pupil expanding element, and the eye of the viewer, a maximum emission angle of the first image light is smaller than a maximum viewing angle of the virtual image, and the diameter of the light flux included in the second image light is greater than that of a light flux included in the virtual image.

摘要： Head-mounted display systems and methods of operation that allow users to couple and decouple a portable electronic device such as a handheld portable electronic device with a separate head-mounted device (e.g., temporarily integrates the separate devices into a single unit) are disclosed. The portable electronic may be physically coupled to the head-mounted device such that the portable electronic device can be worn on the user's head. The portable electronic device may be operatively coupled to the head-mounted device such that the portable electronic device and head mounted device can communicate and operate with one another. Each device may be allowed to extend its features and/or services to the other device for the purpose of enhancing, increasing and/or eliminating redundant functions between the head-mounted device and the portable electronic device.

摘要： A motion detection section 720 detects a motion exceeding a permissible limit in a wide-viewing-angle image displayed on a head-mounted display 100. A field-of-view restriction processing section 750 restricts a field of view for observing the wide-viewing-angle image in a case in which the motion exceeding the permissible limit has been detected in the wide-viewing-angle image. An image provision section 760 provides, for the head-mounted display 100, the wide-viewing-angle image in which the field of view has been restricted.
