  • Patent number: 6914400
    Abstract: A scanning operation is synchronized with the motion of a scan mechanism. Encoder signals indicative of a position of the scan mechanism relative to a scan platen or an object being scanned are received. These encoder signals may include a single channel phase signals are channel A and channel B phase signals. Transitions of the encoder signals are detected. Scan pulses for triggering a scan operation by a scan element are generated based on transitions of the encoder signals. Differences in the encoder signal resolution and a desired scan resolution are compensated for in the generation of the scan pulses. A transfer signal is generated in synchronization with the scan pulses for controlling output of data from the scan element. Variations of the velocity of the scan mechanism cause variations of the frequency at which the scan pulses are generated.

  • Patent number: 6826314
    Abstract: An image size transforming apparatus of the present invention comprises a DDA processing unit which expands or contracts an original image by the digital differential analysis (DDA) to create an expanded or contracted image, and an initial value setting unit which uses a random number based initial value as the sum total initial value for the digital differential analysis. Upon the image contraction, the DDA processing unit figures out the DDA sum total at the current pixel position by adding a contracted image size to the initialized DDA sum total, at the original image pixel initializing position, but to the DDA sum total figured out at the immediately previous pixel position, at the other pixel positions. If the DDA sum total is not less than the original image size, then the DDA processing unit copies pixels at the current pixel position onto a contracted image and defines the result of subtraction of the image size from the current DDA value as the DDA sum total at the next pixel position.

  • Publication number: 20040223169
    Abstract: An image expansion unit expands image data at a resolution higher than the actual resolution of an output apparatus, and a resolution conversion unit converts the expanded high-resolution data to data having the actual resolution of the output apparatus. An exposure setting unit outputs a reference pattern and a density sensor measures the density of this reference pattern. On the basis of the result of measurement, a laser-exposure correction table for an electrophotographic process is created in such a manner that the density of prescribed image data that is obtained by the resolution conversion will be the same before and after image formation. This table is set in a LUT. As a result, it is possible to prevent a situation in which the density and shape of an image are rendered non-uniform and to output a high-quality image in stable fashion.

    Abstract: A scanning or copying system can include imaging elements and one or more system processors that are programmed or adapted to perform image processing methods and algorithms on image data, and in some instances, to enhance the image. Image data is acquired using imaging elements. Some imaging elements may have overlapping or rotated fields of view or employ differing resolutions. For each imaging element, its output is recombined together with the output of one or more other imaging elements. To perform the recombination, the system can extract features in an overlapping region and match these features in multiple images. In some instances, the features matched can be edges. Alternatively, the recombination can be performed by positioning each subimage with respect to a larger image through image matching and location techniques. Parameters from the recombined image can be extracted and these parameters can be used to correct for geometrical and spatial distortions and thereby enhance the image.

    Abstract: Disclosed is a color-file communicating facsimile apparatus that is capable of communicating non-document image files through a simple method. A FIF (Facsimile Information Field) is provided with bits indicating that a color file to be transmitted is an sYCC JPEG-encoded file in which the concept of resolution is absent and bits specifying the sYCC full-color mode. If these bits have been set, a transmitting side sets resolution information and image-width information to any values. If these bits are valid, a receiving side ignores resolution information and image-width information in the FIF and performs print-out using information that has been obtained from header information of the received JPEG file. If these bits are invalid, ordinary transmission, reception and print processing are carried out.

  • Publication number: 20040070794
    Abstract: A scanning method that is able to reduce the scanning period. According to the width of the document to be scanned, a front pixel region, an effective pixel region for actually fetching the image of the document to be scanned, and a post pixel region are set for the optical sensing device. The induced charges belonging to the front pixel region and the induced charges belonging to the effective pixel region with respect to each one of the scanning lines are sequentially fetched out. The induced charges belonging to the post pixel region with respect to each one of the scanning lines are transferred to the front pixel region, so as to be added into the induced charges belonging to the front pixel region for the next scanning line with respect to the scanning lines. The induced charges belonging to the effective pixel region with respect to the each one of the scanning lines are processed into a piece of the image.

  • Patent number: 6700682
    Abstract: An accumulation unit accumulates, in a 1-line element corresponding to the main scanning direction, an electrical signal prepared by photoelectrically converting optical image information obtained by scanning an original image to be formed with a carriage in the subscanning direction. A magnification setting unit sets the copy magnification. A speed change unit changes the moving speed of the carriage in accordance with the copy magnification, and when the set copy magnification is equal to or smaller than a certain magnification in reduction, changes the carriage moving speed to 1/n (n: a natural number larger than 1) from the relationship between the current magnification and the carriage moving speed.

  • Patent number: 6674920
    Abstract: An image processing apparatus which outputs image data by electrically scaling an image in synchronism with a prescribed clock includes a memory with a one-line capacity for storing image data. A write address in the memory is initialized on a page by page basis and is incremented in accordance with a specified magnification ratio and with the position of a specified region, while a read address in the memory is initialized on a page by page basis and is incremented in accordance with the specified. magnification ratio and with the position of a specified region. The incrementing of the read address is started with a delay of one line with respect to the write address, with provisions made to generate an equal number of write addresses and read addresses per line. This makes scaling and translational transformations in the main scanning direction possible while allowing memory write and read operations to be performed simultaneously with a memory capacity of only one line.
