Abstract
An image input/output characteristic is computed from environmental information obtained by a temperature sensor, a photographic printing paper type read by an identification sensor, photographic printing paper characteristic information stored in a photographic printing paper characteristic memory, and previous calibration history information stored in a calibration history memory. Results of computation are output to a laser driver, and an amount of exposure or the like is corrected so as to calibrate a printer. As a result, a number of times that a calibration test pattern is printed and density is measured can be reduced, thereby improving working efficiency and saving photosensitive materials.

An image recording apparatus for recording an image on a photosensitive material wherein a calibration test pattern is outputted based on calibration test pattern data, the
- output calibration test pattern is read, an image input/output characteristic is computed based on the read pattern data, and calibration is carried out, said image recording apparatus comprising:
- photosensitive material characteristic storage means for storing a characteristic of the photosensitive material on which the image is to be recorded;
- environmental information obtaining means for obtaining environmental information which affects changes in the characteristic of the photosensitive material on which the image is to be recorded;
- photosensitive material characteristic reading means for reading the characteristic of the photosensitive material on which the image is to be recorded from said photosensitive material characteristic storage means;
- and
- estimated calibration means for computing an image input/output characteristic for calibration from the characteristic read by said photosensitive material characteristic reading means, previous calibration information including the image input/output characteristic computed at a previous calibration time, and the environmental information at a current calibration time.
