Abstract

A video display system includes: a screen on which an mage for displaying a virtual image is projected; a light source that emits laser light; a scanner that projects the image onto the screen by biaxially scanning the laser light onto the screen; and a controller that generates the image and controls the light source using an image signal for causing the generated image to be projected onto the screen by the laser light, and receives an input of sensing information measured using a temperature sensor and controls the scanner in accordance with the input sensing information. When the sensing information indicates a temperature outside a given temperature range, the controller causes the scanner to reduce an amplitude of the biaxial scanning in at least one axial direction to a smaller value than when the sensing information indicates a second brightness or a temperature within the given temperature range.
