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.

An image scanning apparatus moves a copyboard provided between an original document and three line sensors and the three line sensors relatively to each other at a speed different from the speed of conveying an original document. An in-line correction portion allows three data output by three line sensors to be synchronized so that a foreign object on the copyboard appears at different positions of the original document in chromatic color. A foreign object position detection portion detects a position on the copyboard of a foreign object before an original document is conveyed, and a color determination portion decides a determination pixel for use in determination from a plurality of pixels included in each of scanned data obtained while the original document is conveyed, based on the position of the foreign object, and determines whether the original document is color or black-and-white based on the determination pixel.

An image processing apparatus reducing image noise caused at a device which has a stationary reading portion such as a CCD sensor and reads an image of a document by moving the document is structured as follows: the image processing apparatus determines whether full color image data read by the reading portion is out of a predetermined color space; it uses shift resisters to determine that the image data out of the predetermined color space continues in a sub scanning direction; and thus it detects a line-shaped dirt image caused by dirt or the like at the reading portion, and corrects the dirt image.

An image reading apparatus includes: three line sensors mutually spaced in a sub scanning direction; a platen arranged between the original and the three line sensors; a mover moving the platen at a rate relative to the three line sensors, the rate being different from that of the original relative to the three line sensors; a first detector detecting a noise pixel based on a plurality of data output from the three line sensors; and a second detector detecting a subsequent noise pixel based on the noise pixel detected with the first detector.

An image processing apparatus, comprises: a document reader that reads images printed in a plurality of areas in a document; a printer that prints on a sheet image data read out from the document by said document reader; a security code detector that detects a security code given to each of the plurality of areas in said document; a password detector that detects a password given at least to one of the plurality of areas in said document; an entry requestor that requests a password to be entered; a password judgment part that judges whether or not said entered password is an appropriate one that corresponds to the password detected by the password detector; and a controller that decides an operation performed by said printer, to print image data from the area having the given password, depending on the judgment result drew by said password judgment part.

In order to prevent the appearance of gaps in fine lines when image data undergoes resolution conversion, the image processing apparatus includes an image reading unit that inputs image data, a fine line detection unit 113 that detects fine lines from the image data, a resolution conversion unit 111 that converts the image data to a prescribed resolution, and a fine line restoration unit 114 that restores fine lines in the image data that has undergone resolution conversion.

The image processing apparatus of the present invention includes: a specific pattern detecting unit which detects a background pattern representing additional information from inputted original document image data; an information detecting unit which extracts the additional information represented by the background pattern which is detected by the specific pattern detecting unit; an erase processing unit which erases a prescribed region of the original document image and outputs erase-processed document image data; a re-embedding background pattern generating unit which generates a re-embedding background pattern representing the additional information extracted by the information detecting unit; a background pattern composition processing unit which embeds the re-embedding background pattern into the erase-processed document image data and outputs re-embedded document image data; and a processor which controls the units mentioned above. The apparatus of the present invention is capable of embedding the background pattern again, which has once been lost through the erase function, so as to maintain a background pattern detection rate at a high level.
