摘要:
When it is detected that an external device has been connected, the printing unit is controlled so as to form an image according to image data that has been received from the external device. As a result, image forming can be started earlier compared with the case in which image forming is prepared after the image data is transmitted. Accordingly, the user waits a shorter period of time and the usability is improved.

An image processing apparatus comprising: an input portion that inputs image data of a plurality of pages of document; a password detector that detects a password given to each of the pages; a password judger that judges from the detecting results drew by the password detector whether or not different passwords are detected from each of the pages; a correlation judger that judges about each of the pages if the password judger judges that different passwords are detected from each of the pages, whether or not the passwords are correlated to each other; and an output permitting portion that permits the image data of all the pages, which are the image data inputted by the input portion, to be outputted without requesting entry of all passwords, if it is judged about each of the pages that the passwords are correlated to each other, on the other hand, requests entry of a password about each of the pages if it is judged about at least one of the pages that the passwords are not correlated to each other, then permits the image data of a certain page to be outputted, if an appropriate password is entered about that page.

A background pattern image combining apparatus for combining a background pattern image with an input image is provided. The background pattern image includes a plurality of first isolated points having a size that can be read by an image reader and a plurality of second isolated points having a size that cannot be read by the image reader. The background pattern image combining apparatus includes a detector that detects, in the input image, a specific area which is an area having a specific state, and a combining portion that combines the background pattern image with the input image by placing not the plurality of first isolated points but the plurality of second isolated points in the specific area, and, by placing the plurality of first isolated points and the plurality of second isolated points in an area other than the specific area.
