When a head-mounted display acquires data of a display image generated on the basis of position/posture information of a head of a user at time and given a distortion corresponding to the distortion of an eyepiece lens, the head-mounted display corrects the image on the basis of position/posture information of the head at time t for display. Then, the head-mounted display corrects chromatic aberrations on the basis of actual distortion coefficients of the lens, and outputs the image to a display panel.
