Abstract: A head-mounted display includes an image forming part, a half mirror reflecting a part of an image light emitted by the image forming part toward an optical pupil position, and a wall part. Given that an intersection point between the half mirror and an optical axis of the image light is defined as a first intersection point, an intersection point between the wall part and the optical axis is defined as a second intersection point, a distance between the first intersection point and the second intersection point is defined as a first distance, and an angle at which the wall part inclines with respect to the optical axis is defined as a first angle, the first angle and the first distance are set such that the image light passed through the half mirror and reflected by the wall part reaches a position different from an optical pupil position.

Abstract: A scanning image display includes a light source, a light detector, a scanning section, a storage section, a current controlling section, a reference current section, a sweep section, and a change section. The light detector detects the laser light emitted from the light source. The scanning section scans the laser light. The current controlling section controls laser light by supplying a current supplied to the light source. The storage section is configured to store a reference current value, a reference light output value, and a gamma table. The reference current section supplies the reference current value to the current controlling section. The sweep section sweeps current values supplied to the current controlling section to obtain one current value where the detected laser light corresponds to the reference light output value. The change section changes the gamma table based on the one current value obtained by the sweep section.
