Abstract
A display apparatus comprises a mirror oscillating about a first axis upon excitation by a first excitation signal and about a second axis upon excitation by a second excitation signal, a light source projecting a light beam onto the mirror for deflection towards an image plane, the light source being controller according to pixels read-out by an image processor from a buffer, a gaze tracker detecting a user's region of interest, ROI, within the image plane, and a controller modulating one of the excitation signals by a modulation signal which is dependent on the ROI such that the number of passes of the light beam per unit area is higher in the ROI than in a region outside thereof, wherein the number of pixels read-out per unit area by the image processor is higher in the ROI than in a region outside of the ROI.
