Abstract: The invention preferably relates to an image-generating unit with a light source for generating illumination radiation and a light-modulating pixel array for generating an image by pixel-wise modulation of the illumination radiation incident on the pixel array. The image-generating unit is characterized in that the illumination radiation, upon incidence on the light-modulating pixel array, has a lateral extent which is smaller than the pixel array and is guided over the pixel array by means of a scanning unit for generating an image. By a combination of the process of scanning the illumination radiation over the light-modulating pixel array, the speckle signatures of the scanning unit and of the pixel array are superimposed or combined to generate an image point. Advantageously, visible speckle patterns in the resulting image can thus be significantly reduced.
