Abstract

According to the present invention there is provided a method of projecting an image, the method comprising the steps of, providing light signal which is configured such that it can be projected onto a display surface to display an image; oscillating a first reflective surface, to scan the light signal over the display surface, using an actuator which is in operable co-operation with the first reflective surface, by applying a first actuation signal to the first reflective surface, wherein a rise time or fall time of the first actuation signal is inversely proportional to a resonant frequency of oscillation of the first reflective surface.
