1. US20070247650 - Adjustment for output image of image data

If a memory card MC is inserted in a slot 34, a control circuit 30 of a color printer 20 acquires image output control information GI from the memory card MC and analyzes this information. A CPU 31 modifies a brightness standard value Bstd corresponding to a brightness parameter by taking account of a preset exposure bias value when an exposure bias value other than zero is set. The CPU 31 determines the brightness correction level Brev by correcting the brightness representative value Brep so as to bring it closer to the brightness standard value Bstd that has been modified, and adjusts the image quality of image data by taking account of the brightness correction level Brev. As a result, the image quality of image data can be automatically adjusted without degrading output conditions that have been set arbitrarily.
