Image processing apparatus, method, and program product for correcting reproduction characteristics based on differences between first and second formed charts and target values

摘要

An image processing apparatus includes a first determination unit configured to determine whether a difference between the result of measuring a first chart formed by an image forming unit and a target value is larger than a first preset threshold value, and a control unit configured to, based on a result of determination by the determination unit, control execution of correction of reproduction characteristics of an image formed by the image forming unit by using the result of measuring a second chart formed by the image forming unit and the target value.
