    Abstract: An imagery data memory addressing mechanism writes data representative of respective pixel values of an image into and reads out of immediately successive storage locations of memory, irrespective of whether the number of pixels in the image is the same as or less than the number of storage locations of memory, facilitating the use of a DMA controller and reducing access time. Data values associated with successive pixels of a first line of the m lines of the m.times.n image are stored in successive first through n storage locations of the framestore memory and data values associated with successive pixels of successive ones of second through m lines of the image are stored in successive (n+1) through mn storage locations of the framestore, so that there are no unused or dummy memory locations (in which `fill` data is inserted) between those memory addresses associated with the first line and the last or mth line of the image. Once the framestore has been loaded with pixel data of the image of interest, all or a selected portion of the image may be accessed and coupled to an output device the spatial resolution of which may differ from that of the stored image. Also, the coordinates of the pixels of the selected portion of the output image array need not necessarily coincide with spatial locations of the pixels of the stored image. To read data out of the framestore, pixel code values stored in respective pluralities of memory storage locations associated with respective neighborhoods of pixels surrounding respective ones of pseudo pixels of the output image are weighted and combined.

    Abstract: In an image forming apparatus having two-face copy mode, an image reader can read a document image placed on a platen along a subscan scan direction and along a direction reverse to the subscan direction. The image reader includes an image sensor for reading a document image along a main scan direction and along a direction reverse to the main scan direction. In the normal image mode and in the reverse image mode, a normal image and a reverse image of a document are formed by controlling the reading direction and the subscan direction. When a stapler is used to staple a plurality of copy papers, but at positions in the papers which are not appropriate to turn over them if normal images are formed on the papers, the reverse image mode is set for forming a normal image of the document. Further, when a back face is printed in two-face copy mode, it is decided if the back face is placed on the platen so that the image in the back face is reproduced as a reversed image to the image in the front page according to document direction (portrait document or a landscape document), a position of margin, and a direction of the document with respect to document feed direction. The scan mode is changed when it is decided that the document is placed on the platen so that the image in the back face is reproduced as a reversed image to the image in the front page.

    Abstract: An image processing apparatus and corresponding methods which include a means for determining whether image information of documents read by an image reader can be entirely stored in a storage device prior to performing image processing. The apparatus comprises, in part, an arithmetic operation component which calculates the number of sheets of the documents, (the image information of which are supplied through an image input device such as a scanner so as to be stored in a compressed state) corresponding to the residual storage capacity of a storage device. The apparatus also includes a display device for displaying the number calculated by the arithmetic operation component.

    Abstract: The object of the present invention is to provide an image forming apparatus capable of enabling high-speed continuous copy of an same single-color image, wherein the apparatus is incorporated with a shift register between an image reader and a laser beam generated for performing imagewise exposure onto a photoreceptor. The shift register has a circulation circuit connecting between an output and an input side thereof. After an image data corresponding to a sheet of original document is inputted into the shift register, the circulation circuit is actuated and circulates the image data, thereby repeatedly outputting the image data to the laser beam generator by the number of required times.
