<p>The invention relates to a projector for projecting an image, having an illumination modulator (3) charged with light, having multiple illumination pixels, which are disposed in columns and lines and can be actuated independently of each other in order to modulate the intensity of the light in a pixel-individual manner, a projection lens (4) connected downstream of the illumination modulator (3), said lens projecting the light being modulated in a pixel-individual manner onto an image modulator (5) having multiple image pixels, which are disposed in columns and lines and can be actuated independently of each other in order to generate the image having been projected in this manner such that either exactly one image pixel is associated with each illumination pixel, or multiple image pixels are associated with each illumination pixel, and a controller (7) to which image data (BD) of the image to be generated is fed and which generates illumination control data (MS) for the illumination modulator (3) and applies the same for the modulation of the light, and which generates image control data (BS) for the image modulator (5) and applies the same for image generati-on. The illumination control data (MS) has either an on-value in order to illuminate the associated image pixel or the associated image pixels of the image modulator for the image generation utilizing the light coming from said illumination pixel, or an off-value in order to minimize the intensity of the light coming from said illumination pixel and projected onto the associated image pixel or the associated image pixels for each illumination pixel, and wherein the illumination control data (MS) is generated such that the same has the on-value for each illumination pixels being associated with one, or at least one image pixel that is to represent a brightness value within the image that exceeds a predetermined threshold value according to the image data, and an off-value for all other illumination pixels, with the exception that the illumination control data for at least one of the other illumination pixels, the associated image pixel, or the associated image pixels.</p> |
