Abstract: The direction of the document in the original image read by an image reader unit (101) is discriminated by a document direction discrimination unit (102). 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 (103) diagnoses the document direction discrimination unit (102) 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 (109), and executes the above processing.

Abstract: An image processor performs a high accuracy orientation determination process on a color image. A color component analyzer determines a frequency of appearance of each color component based on color image data of an input original document, and an orientation determining block determines the orientation of the original document by a character recognition process based on the frequency of appearance result. The color image data is then subjected to a predetermined editing in accordance with the determination results, and the edited image data is output.

Abstract: 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°. Images are copied in the designated layout.

Abstract: A system enables the reading characteristic of an image reader in a network to be recognized by a host computer. The SP server device transfers the reading characteristics of a plurality of scanner printers to a designated client host computer and through a network.

Abstract: An image processing apparatus includes an image input device for photoelectrically converting a document image which has been optically read and for inputting the converted document image as image data. An area separator separates a plurality of areas included in the input image data from one another and a character recognition is performed from a plurality of directions with respect to character data in the image data input by the image input device with reference to a character recognition dictionary. The apparatus performs a first discriminating function of discriminating, for the plurality of areas separated by the area separator, respective reliabilities in a plurality of directions on the basis of results of the character recognition, and second discrimination function for discriminating a document direction on the basis of average values of the reliabilities discriminated by the first discriminating function.

Abstract: Document image data entered from a scanner are separated into a plurality of areas by an area separation unit. Attributes are assigned to respective ones of the plurality of partial areas obtained in the area separation unit. For instance, a character area in the main body of text and a character area in a table are examples of area attributes. Each of these attributes is assigned a degree of priority in advance. A character recognition/orientation discrimination unit detects character orientation in each of the plurality of partial areas and discriminates document orientation. The orientation of the document image data is determined based upon the document orientation of each partial area discriminated by the character recognition/orientation discrimination unit and the degree of priority of the attribute assigned to each partial area.
