Abstract
A photographic processing apparatus according to the present invention exposes photographic papers using a laser beam modulated based on image data and includes a laser beam emitting device. A changeover part changes the level of a driving signal to any one of a plurality of discrete levels according to a coloring characteristic of the photographic paper. The level of the driving signal determines the intensity of the laser beam outputted from the laser beam emitting device in a plurality of levels (for example, three levels consisting of a high level, a middle level and a low level). A filter is also provided to reduce the intensity of the laser beam outputted from the laser beam emitting device.
