Image processing apparatus and image processing method

This invention provides the following environment. That is, an original document file corresponding to a document to be copied is specified from image data of that document to be copied, and a print process is made based on the specified file so as to prevent deterioration of image quality. Also, when a document to be copied is not registered, a registration process is executed to suppress deterioration of image quality in an early stage. Furthermore, since the document is converted into vector data, re-use of such document is facilitated, and deterioration of image quality can be suppressed even when an image process such as enlargement or the like is made. To this end, when an original digital file cannot be specified, an apparatus of this embodiment executes a vectorization process (S), converts the obtained vector data into a data format that can be re-used by an application (S), and registers the converted file in a file server (S). With this registration process, since the location of the file is settled, that location information is composited on an image to be scanned using an identifier such as a two-dimensional barcode or the like (S), and the composite image can be printed (S). Even when the printed document is scanned again, a registered digital file can be easily specified.

Image processing method, system, program, program storage medium and information processing apparatus

A user designates a two-sided copying mode, a reduced-scale copying mode, a vertical or horizontal binding direction, and the like from a control panel. An original image is magnification-varied at a designated reduction magnification, and the reduced image is stored in a page memory. In the case of an odd page (front surface) in a single-sided or two-sided copying mode, a &ggr; conversion circuit reads out and outputs stored image data in the normal order, thus forming images. On the other hand, in the case of an even page (back page) in the two-sided copying mode, whether the horizontal or vertical binding direction is designated is checked. If the binding direction agrees with the reversing axis direction of a paper sheet upon copying, images are read out in the normal order. When the vertical binding direction is designated, images are read out in an order opposite to the normal order, so that each page is rotated through 180&deg;. Images are copied in the designated layout.

Image forming apparatus and method

Disclosed is an image forming apparatus capable of performing image formation by automatically discriminating and correcting the direction of an original without sorting originals including both portrait and landscape ones. Image data is read, and the direction of the read image is discriminated. In accordance with the discrimination result, a synthesis image to be synthesized suited to the direction of the image is selected. The synthesis image is rotated, where necessary, so that the synthesis image points in the same direction as the read image, and the two images having the same direction are synthesized and output.

Image processing apparatus and method

An image block is detected by raster scanning an input image and chasing surrounding black pixels around a detected black pixel as the start point in sequence. Further, by judging the feature of the detected image block, the attribute of the image block can be judged. Also, by comparing the detected image block with a predetermined window, it is possible to determine whether or not the image block is noise, whereby image processing of higher accuracy can be effected.

Image processing method and apparatus for discriminating an input image area or an attribute of image information in the discriminated area

The direction of the document in the original image read by an image reader unit (,) is discriminated by a document direction discrimination unit (,). Rotation processing and the like are performed for the original image in accordance with the discriminated direction. The resultant image is output onto a recording paper sheet. When a fault diagnosis unit (,) diagnoses the document direction discrimination unit (,) and determines that the unit is faulty, the image processing apparatus recognizes the direction of the document in the original image on the basis of information provided from the operator through an operation unit (,), and executes the above processing.

Image processing apparatus and method which process image on the basis of direction of document

The type of a document placed on the platen of an image forming apparatus is designated by the operator, a character area in the document is discriminated based upon an image signal obtained by reading the document, the orientation of the document is sensed based upon the discriminated character area and the type of document designated, and the image signal is processed based upon the sensed orientation of the document so as to obtain correctly oriented text at output of a prescribed image, such as a double-sided print image or layout of images of reduced size.
