Aspects of the subject technology relate to an image generation device that generates an image with good white balance while preventing burn-in of a liquid crystal element, and a head-up display. A light adjustment unit includes a liquid crystal element for adjusting a polarization angle of laser light, and adjusts the polarization angle of the laser light in order to adjust the intensity of laser light that is oriented in an emission direction. A light detection unit detects the light intensity of the laser light (reflected light) that has passed through the light adjustment unit. A control unit corrects outputs of a plurality of light sources based on the light intensity of the laser light (reflected light) detected by the light detection unit at a timing different from a timing at which a voltage applied to the liquid crystal element is reversed.
