Document Size Detection Patents (Class 358/449)
  • Patent number: 7813010
    Abstract: A driving unit drives an illuminating light. An image pick-up device reads a document in a main-scanning direction. An optical unit projects an image of the document onto the image pick-up device. An extracting unit extracts image signals at a plurality of points in the main-scanning direction of a first position and a second position in a sub-scanning direction. A document detecting unit creates binary data indicating a presence of the document at each of the points based on the image signals extracted. A size detecting unit determines a size of the document in the main-scanning direction based on a distribution of presence and absence of the document.

  • Patent number: 7808663
    Abstract: The image forming apparatus receives image data based on multiple document images of various sizes and/or orientations. The apparatus identifies areas that are not yet assigned with document images on a single sheet of paper and identifies whether any document image can be laid out in an identified area. In another aspect of the apparatus, a maximum document image size is detected from multiple document images, and a scale factor is calculated to cause the detected maximum size match with the size of the entire area of the paper or an area obtained by dividing the paper into equal parts. In another aspect of the apparatus, a scaling factor is calculated for each document image to cause the size of the particular document match with the size of an area obtained by dividing the paper into equal parts.

    Abstract: There are provided an image generating apparatus, method, program, and recording medium that eliminate the need for specifying the size of paper on which a captured image is to be printed and are capable of printing the image on paper of a suitable size even when information about the paper size is unavailable. An MFP 101 obtains an image from a device such as a digital camera 105, extracts pixel count information from the image, and determines whether or not the image contains resolution information. If the image does not contain resolution information, the image is transformed to an image of a size that fits an A4-size sheet and the resolution of the image is determined on the basis of the pixel count information. Then, the size-transformed image is printed on an A4-size sheet with the determined resolution.

  • Publication number: 20090122357
    Abstract: An original size detecting apparatus is capable of carrying out accurate original size detection without erroneous detection of the size of an original due to the influence of external scattered light. A CCD reads reflected light of light irradiated from a light source onto an original placed on an original platen glass. Optical sensors detect two open states of the original presser plate, and a scanner controller performs predetermined control corresponding to each of the open states of the original presser plate detected by the optical sensors, to determine the size of the original based on the result of the reading by the CCD.

  • Publication number: 20090109496
    Abstract: In an image reading device, a reading unit scans first rectangle regions located within a maximum reading area equivalent to a maximum size of a document that can be scanned and acquires image data from the first rectangle regions. A transporting unit moves the reading unit to the first rectangle regions in a direction of movement opposite to a direction of movement in normal document reading. A document size judging unit detects whether a document exists in each first rectangle region based on the image data acquired by the reading unit and a predetermined threshold, so that a size of the document is judged. The reading unit is arranged to scan second rectangle regions located outside the maximum reading area, the second rectangles being different from the first rectangle regions, and acquire image data from the second rectangle regions.

  • Patent number: 7489416
    Abstract: An MFP can transmit image data read by a scanner by attaching it to E-mail. At the time of transmission, the image data input by the scanner and stored in a work memory is converted into mail data so as to be transmitted by E-mail, and the mail data is stored again into the work memory. The mail data is divided every predetermined reference data size into divided files which are sequentially transmitted as divided mails. When completion of transmission of divided mails corresponding to a unit image is confirmed, the image data and mail data of the unit image are eliminated from the work memory. By sequentially performing such a process, the memory use efficiency can be improved while holding image data of a unit image which has not been transmitted yet.

  • Patent number: 7433098
    Abstract: A document processing system comprising an image capture subsystem for capturing selected image metrics and at least one image rendition from a plurality of documents and for determining if at least one of the selected image metrics for any of the at least one image rendition does not successfully compare against preselected image quality metric threshold values. An image quality flag is generated for any of the at least one image rendition if it does not successfully compare, and a record entry for each imaged document having at least one flagged image rendition is created in an image quality flag file. An image index file for individually accessing the image renditions is modified to include a reference to the corresponding image quality flag file record entry The document processing system may optionally compare selected document metrics against preselected document metrics in a similar manner.

  • Patent number: 7391917
    Abstract: Stored digital data is searched for on the basis of an input image, difference information is extracted by comparing the retrieved digital data and the input image, and the difference information is composited to the digital data. Digital data generated by composition is stored. When no digital data is retrieved, the input image is converted into vector data, and the image that has been converted into the vector data is stored as digital data. Obtained region segmentation information and an input image are composited, the composite image is displayed on an operation screen of an MFP, and a rectangular block to be vectorized is designated as a specific region from the displayed region segmentation information. A user designates the specific region by designating rectangular blocks in an image using a pointing device.

  • Patent number: 7376258
    Abstract: An image quality assurance method for identifying image defects in a plurality of previously-imaged documents, where each previously-imaged document includes at least one image rendition stored in at least one image rendition file according to type of image rendition. The image renditions are analyzed to provide selected image metrics, the latter of which are compared against preselected image quality metric threshold values. An image quality flag is generated for any image rendition if at least one of the selected image metrics for that image rendition does not successfully compare against the preselected image quality metric threshold values. A record entry is created in an image quality flag file for those documents having at least one flagged image rendition, the record entry including information about the selected image metrics of the at least one flagged image rendition for that imaged document.

  • Publication number: 20080080016
    Abstract: An image forming system includes a first data compressing device, a data decompressing device, and an image forming device. The first data compressing device stores image data of a top line to be formed on a recording medium first and image data of a designated line other than the top line in a memory area with a data format capable of forming the original image data by itself, while generating difference data which indicates a difference between image data of a non-designated line other than the top and the designated lines and the image data of a line adjacent to the non-designated line, and stores the difference data in the memory area. The data decompressing device sequentially decompresses the image data of each line, based on the image data and the difference data. The image forming device forms an image on the recording medium, based on the decompressed image data.
