Claims5
An image printer comprising:
- a first exposure unit for projecting and exposing image information of a negative film on to a negative-film photosensitive material adapted for a negative film, said first exposure unit including a projection-exposure light source and a light modulating filter for adjusting balance of a light from said light source to be irradiated on to the negative film;
- a second exposure unit for exposing the image information of the positive film on said negative-film photosensitive material;
- a control unit for controlling operations of said first and second exposure units as well as of said transport means;
- and
- an image sensor for reading the image information of the negative film or the image information of the positive film supplied to said first exposure unit;
- said control unit controlling the light modulating filter of the first exposure unit based on the image information of the negative film read by said image sensor, and said control unit converting the image information of the positive film read by said image sensor into image information to be exposed on said negative-film photosensitive material.
