Image processing software is penetrating every aspect of the artistic creation. And the auxiliary function of image processing software is becoming more and more significant in modem art creation, which has greatly changed the creation concept of lots of modem art workers. Thus, the created works are also becoming more and more colorful. First of all, this paper explains several kinds of common digital processing principles in image processing software. Based on this, this paper uses the cases to make a conduct empirical analysis on the auxiliary function reflect and principle of image processing software in modem arts creation. And then, it is the development prospects of image processing software in modem arts creation that has been deeply analyzed. It further explains the advantage function of digital image processing software applied in modem arts creation. Thus, to a certain extent, it provides a scientific theory basis for research in the field.
