Claim:
An image processing method comprising: a holding step for holding an original database in which a correction condition corresponding to a reproducing property of an output unit is stored; a forming step for, as calibration processing, acquiring from the original database a gradation correction table, the gradation correction table corresponding to a recording medium to which image output is executed and head rank information of a head used in said output unit to create a new database, wherein the calibration processing not only creates said new database but also forms a management file indicating the new database has already been created; and a correction processing step for effecting correction processing regarding input data by using the created new database, wherein, when the image output is executed by said output unit, it is confirmed whether or not a new database file corresponding to the head used in said output unit has already been created, and wherein the creation of the new database file is executed if it is confirmed that the new database file is not yet created, and the creation of the new database file is not executed if it is confirmed that the new database file has already been created.
