ABSTRACT:
An image printer includes a projection exposure unit for projecting and exposing an image of a film onto a photosensitive material, an image exposure unit for exposing the photosensitive material based on exposure image information with setting an exposure amount for each of a number of areas of the photosensitive material, a transport device for transporting the photosensitive material through the projection exposure unit and the image exposure unit, a reader device for reading the image information of the film with dividing the image information into a number of areas, and a correction information inputting device for inputting a correction-target portion of the image information read by the reader device and a correction content for the correction-target portion. Based on the image information read by the reader device and on correction information instructed by the correction information inputting device, the image exposure unit generates, as the exposure image information, image information concerning only the correction-target portion corrected in accordance with the correction content. The transport device transports the photosensitive material in such a manner that the projection exposure by the projection exposure unit and the exposure by the image exposure unit are effected in an overlapping manner onto the photosensitive material.
