<p>In a photographic printer (10) using a laser scanning unit (100, 200) for exposing a latent image corresponding to an image data on a sensitized surface of a photographic paper (1A), intensities of the laser beams exposing the photographic paper is adjusted corresponding to a variation of an actual sensitivity of the photographic paper and deterioration of a developer with respect to nominal values of them. At least the intensities directly emitted from laser light sources (104R, 104G, 104B), or values of optical modulation data for modulating the laser beams corresponding to the image data are varied. Alternatively, transmittances of optical elements such as polarizing beam splitters (110R, 110G, 110B) provided on optical paths are varied for adjusting the intensities of the laser beams. <IMAGE></p> |
