Abstract
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.
