摘要： A virtual image display device includes: an image projection device that projects an image light; a diverging element on which the image light emitted from the image projection device is incident, spreading the image light out over a range of a predetermined angle; and a light branching element that reflects the image light emitted from the diverging element, while transmitting the incident light from the surface other than the reflecting surface. The image light from the image projection device is formed into an image on the diverging element. A virtual image of the image formed on the diverging element is generated on an extension line in the opposite direction to the emission direction of the image light reflected from the light branching element. Further, an optical axis converting element is provided to convert the optical axis of the image light emitted from the image projection device, into a predetermined direction.

摘要： A light irradiation device to display an image by light irradiation prevents easy perception of distortion occurring in the displayed image due to vibration of the device or movement of viewpoint. A random number is generated, and the refresh rate of the displayed image is distributed at random in correspondence with the random number. The light emission intensity is changed in correspondence with the refresh rate. When the number of lines is changed, the input video signal is subjected to scaling and a display is produced. The refresh rate is changed in correspondence with the frequency of the vibration detected with the vibration monitor.
