The purpose of the present invention is to provide an image generation device capable of generating an image with good white balance while preventing burn-in of a liquid crystal element, and a head-up display. A light adjustment unit 14 includes a liquid crystal element 14a for adjusting a polarization angle of laser light C, and adjusts the polarization angle of the laser light C in order to adjust the intensity of laser light C that is oriented in an emission direction. A light detection unit 16 detects the light intensity of the laser light C (reflected light C1) that has passed through the light adjustment unit 14, and a control unit 20 corrects outputs of a plurality of light sources 11a, 11b, 11c on the basis of the light intensity of the laser light C (reflected light C1) detected by the light detection unit 16 at a timing different from a timing at which a voltage applied to the liquid crystal element 14a is reversed.
