A head-mounted display configured to enhance the ease of wearing work and the stability of wearing is provided. A wearing band has an extending section and a movable section that is movable relative to the extending section in the length direction of the wearing band.

A system may include a processor, a night vision sensor, and an objective lens assembly comprising four lenses. Each of a first lens, a second lens, a third lens, and a fourth lens may be configured to project a real world scene onto one of four portions of the night vision sensor. The night vision sensor may be configured to provide four images of the real world scene from the objective lens assembly to the processor. The processor may be configured to: receive a first image, a second image, a third image, and a fourth image from the night vision sensor; generate color night vision image data based at least on the first image, the second image, the third image, and the fourth image; and output the color night vision image data.

This disclosure describes a system configured to present primary and secondary, tertiary, etc., virtual reality content to a user. Primary virtual reality content may be displayed to a user, and, responsive to the user turning his view away from the primary virtual reality content, a sensory cue is provided to the user that indicates to the user that his view is no longer directed toward the primary virtual reality content, and secondary, tertiary, etc., virtual reality content may be displayed to the user. Primary virtual reality content may resume when the user returns his view to the primary virtual reality content. Primary virtual reality content may be adjusted based on a user's interaction with the secondary, tertiary, etc., virtual reality content. Secondary, tertiary, etc., virtual reality content may be adjusted based on a user's progression through the primary virtual reality content, or interaction with the primary virtual reality content.

An object is to allow a user to watch a moving image more comfortably. A control section (20) includes: a displayed area correcting section (25) configured to make a correction of a location of a displayed area in a whole image so as to follow a specific subject contained in the moving image; and a follow-degree deciding section (24) configured to decide, in accordance with a displacement of the specific subject per unit time, a degree to which the specific subject is followed in the correction.

A head up display includes: a display source configured to project a correction image and a corrected driving information image onto a transflective component; a polarization controller configured to control a polarization direction of light emitted from the display source; a receiver configured to receive a distorted correction image displayed on the transflective component; and a processor connected with the receiver, and configured to compare the distorted correction image received by the receiver with a correction image pre-stored in the processor to obtain a first image distortion, and to correct a driving information image to be displayed according to the first image distortion to obtain the corrected driving information image.

A head-mounted display configured to enhance the ease of wearing work and the stability of wearing is provided. A wearing band has an extending section and a movable section that is movable relative to the extending section in the length direction of the wearing band.

A head-mounted display includes a wearing portion, a display body, a first strap, a second strap, an adjustment assembly, and a switching assembly. The display body is connected to the wearing portion. The first strap and the second strap are respectively connected to two opposite sides of the wearing portion. The first strap, the second strap, and the wearing portion define a wearing space, and the first portion of the first strap and the second portion of the second strap are overlapped with each other. The adjustment assembly is adapted to be coupled to the first strap and the second strap and is configured to adjust the degree of overlap of the first portion and the second portion to thereby change the wearing space. The switching assembly is disposed at the adjustment assembly to switch the adjustment assembly to a coupled state or a decoupled state.
