The present invention includes a control apparatus that (i) receives, from a multifunction peripheral, information indicative of image process content selected by the user, (ii) detects, in correspondence with image processing function information stored in advance, an image process section that can carry out an image process, and (iii) causes the detected image process section to carry out the image process. This arrangement makes it possible to easily use, at the multifunction peripheral, an image processing function that can be performed by an image processing apparatus.
