In the order receiving system of the invention, a read/record controller reads image data from a memory card, produces uniquely recognizable ID information and stores the image data in a memory in association with the ID information. An order form issue section issues the user with an order form including the ID information, a thumbnail of the image data associated with the ID information and a blank field for entry of order information on the image data corresponding to the thumbnail. A scanner reads the ID information and order information from the order form filled with the order information by the user. A readout controller stores the order information in the memory in association with the image data corresponding to the ID information.

System for receiving order for output of image data

In an exposure device according to the present invention, a plurality of exposure bands each containing multiple dots is formed on photographic paper by repeating main scanning in a main scanning direction based on image data that contains multiple pixels and the transfer of the photographic paper in a sub scanning direction. Of the multiple dots contained in each of two continuous exposure bands, the mean value of the pixel levels of two pixels corresponding to two dots with the same positional relationship for the main scanning direction is calculated to derive interpolation data. Thus, the region between the two dots neighboring in the sub scanning direction on the photographic paper is exposed on the basis of the interpolation data.

Exposure device and exposure method for exposing a photosensitive medium to light on the basis of image data containing multiple pixels

In a photographic printer using a laser scanning unit for exposing a latent image corresponding to an image data on a sensitized surface of a photographic paper, intensities of the laser beams exposing the photographic paper are 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, 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 provided on optical paths are varied for adjusting the intensities of the laser beams.

Photographic printer having varied intensities or optical modulation data for laser light sources

An optical scanning device which performs an exposing operation with respect to a photosensitive material such as a printing sheet, etc., by scanning with laser beams in respective colors modulated according to image data is arranged so as to modulate light beams in respective colors projected from respective light sources of a red LD, a green-color SHG laser unit and a blue-color SHG laser unit by AOMs according to image data. Then, the clock frequency control section adjusts an exposure scanning clock for each of the AOM drivers for driving these AOMs individually. It is therefore possible to suppress an aberration in color caused by a shift in light beams in respective colors which are to be projected onto the same target position.
