An image processing apparatus is provided with a display device to display images on a display screen so that the images displayed on the display device can be edited and processed for joining of the images. The image processing apparatus includes an image specifying device to specify two or more images to be joined together on the display device. An image arranging device arranges the images specified by the image specifying device in such an order as to join the images together, and a display control device controls the display device to display the images arranged by the image arranging device. A joining point specifying device specifies any one joining point for each image so that vertically or laterally adjacent images displayed by the display control device can be joined together by referring to the joining points. A joining device joins adjacent images together by referring to the joining points specified by the joining point specifying device. This makes it possible to easily join the images together by such a way as to merely specify one joining point for each image, and hence to execute image joining easily and efficiently.
