Abstract
A magnetic head and line sensor are mounted along the transport passage of a color negative film. The magnetic head reads trimming information recorded on a magnetic recording layer of the negative film, and sends the trimming information to an image processing unit. The line sensor scans an original frame of the negative film synchronously with the transportation of the film and reads the image data of the frame one line after another. In accordance with the trimming information, the image processing unit generates image data for a trimmed image so as to fully use the width of the color paper, and sends the image data to a line printer unit. The line printer unit scans a light beam synchronously with the transportation of the color paper, to record the trimmed image, one line after another, on the color paper. According to a preferred embodiment of the present invention, at least two layers among cyan, magenta, and yellow coloring layers are made of photosensitive material sensitive to nonvisible electromagnetic waves such as infrared light.
