    Abstract: A multiple camera automatic digitizer includes a plurality of spaced video cameras (19) mounted within a housing (3) under a transparent digitizing surface (51). Multiplexing circuitry (37) multiplexes video signals from a selected video camera into a video amplifier (51), the output of which is converted to a digital number representing the darkness of the point of the document most recently scanned by a presently selected one of the video cameras. In accordance with the invention, the automatic digitizer includes a microprocessor (111), system controls that allows selection of various ones of the video cameras to achieve digitizing of corresponding areas of a large document, and computes skew correction factors for each camera as the basis of digitizing of a plurality of permanent alignment marks (P) on a bottom surface of a cover (11) for the digitizing surface. The skew correction factors are used to skew correct the camera data produced by the corresponding camera. The skew corrected lateral offset of each camera is computed by the microprocessor on the basis of the digitized coordinates of the alignment points and is used to automatically compute skew corrected, offset corrected document coordinates for all of the video cameras.

    Abstract: An image joining method for a scanner that scans and transfers image data to a terminal is provided. During scanning and data transfer, when the image data stored in a register is full, an image processor stops the scanning of a linear photodetector. Meanwhile, a matrix photodetector fetches and stores the image of a code strip. Then, the photodetectors are moved backward a distance larger than that being required to be accelerated forward when the scanner resumes scanning. After the data in the register being transferred and cleared, the linear photodetector resumes scanning at a normal moving speed. The code strip image is further fetched and compared with the stored one to get a joining point of scanned image data. By the joining point, the new and prior image data portions are joined and the scanning proceeds, and joined image data will not be overlapped or broken.

    Abstract: There exists a problem that, for registration correction, carrying out less-than-one-pixel-basis correction and one-pixel-basis correction for an image after half toning using screen processing causes unevenness in density when it is hard for linearity of image density against a PWM to come out. Processing of interpolation is carried out so that the way how a halfdot is formed may always becomes the same after the interpolation processing. By applying a matrix in consideration of a dot direction which may be broken by the interpolation processing at the time of the screen processing, conversion in which a way of locating the half dot maintains relation of vertical inversion in a subscanning direction is carried out, and less-than-one-pixel-basis correction is carried out.

    Abstract: A printer not optically correcting bends and inclinations of scanning lines needs to execute such control as to electrically correct them. However, a conventional correction method has a problem that this correction causes an image defect such as an image streak or an uneven density in a specific area. A correction method of the present invention, when an input image has only one color, executes only correction by a second correction component which corrects distortions in a main scanning direction without executing correction by a first correction component which corrects bends and inclinations in a sub-scanning direction, and when an input image has two or more colors, executes both of correction by the first correction component and correction by the second correction component. This control can reduce the frequency of occurrence of an image defect.

    Abstract: Image distortion is corrected in a color printer wherein print units for a plurality of colors are aligned to form a color image by superposing images formed by the print units. A quantity of image distortion is detected, and correction data of main scan address and subscan address are calculated and stored according to the detected image distortion for each main scan address. When input color image data are corrected, printing position is corrected in combination of address change with density interpolation. When the correction data exceeds the maximum correction range, the correction data are replaced by the maximum in the correction range to utilize the capability of the distortion correction of the printer. Further, in the image data correction, after the image data are converted to data having a smaller number of gradation levels, the data are delayed according to the serial arrangement of the print units. Then, the delayed data are converted again for printing.
