  • Patent number: 9832378
    Abstract: Special blend operations for wide area-of-view image generation utilizing a “floating auto exposure” scheme are described. Pixel values in the two images being stitched together are blended within a transition band around a “seam.” identified in the overlap region between the images after changes in exposure and/or color saturation are accounted for. In some embodiments, changes in exposure and/or color saturation are accounted for through the use of one or more exposure mapping curves, the selection and use of which are based, at least in part, on a determined “Exposure Ratio” value, i.e., the amount that the camera's exposure settings have deviated from their initial capture settings. In other embodiments, the Exposure Ratio value is also used to determine regions along the seam where either: alpha blending, Poisson blending—or a combination of the two—should be used to blend in the transitional areas on each side of the seam.

The predetermined image sensor is an image sensor which outputs an offset signal to the common signal among the plurality of image sensors. The feedback signal indicates a completion of an output of image signal to the common signal line. The predetermined image sensor outputs the offset signal to the common signal line in response to the feedback signal.

  • Publication number: 20130278980
    Abstract: A method for converting a hard copy original to a digital image by a scanner system having an image line sensor and a transport system for transporting the hard copy original across the image line sensor are provided. The scanner system has several modes of operation, each mode being associated with a predefined original type and each mode assembling either grey lines or color lines for composing the digital image. The method includes determining an optimal mode of operation for converting the hard copy original by transporting a first part of the hard copy original across the image line sensor. Grey lines from the image line sensor are used in the determination, because this allows the hard copy original to be transported three times as fast across the image line sensor. It is still possible to discern originals with color information from scanned originals with only black-and-white information.

  • Patent number: 8537432
    Abstract: In an image reader, the first reading unit outputs first image data corresponding to the image of the first surface of the original document. The second image reading unit outputs second image data corresponding to the image of the second surface of the original document. The image process circuit acquires at least one of a part of the first image data and a part of the second image data from the storing unit, and performs an image process on the image data acquired from the storing unit. When the image process circuit finishes performing the image process on either the first image data or the second image data, the initialization instruction unit instructs initializing either the first setting or the second setting corresponding to the either the first image data or the second image data and the image process circuit initializes the either the first setting or the second setting.

  • Patent number: 8432583
    Abstract: An image-data acquiring unit acquires image data of an image. An image processing unit performs a predetermined image processing on the image data. A signal generating unit generates a scanning signal for determining a section of the image data for performing the image processing. A signal control unit stores waveform information of a scanning signal in a normal operation as a control signal, compares the control signal with the scanning signal generated by the signal generating unit, and detects an abnormality of the scanning signal. A scan control unit determines whether the image processing is to be continued based on a result of detection by the signal control unit.

  • Patent number: 8363291
    Abstract: In a method of scanning an image on an original, an optical sensor including sensor elements for each of a number of basic colors is used to generate pixel values of rows of pixels of the scanned image. The sensor elements are used to generate grey scale pixel values representing different parts of the image. A first sensor element for each of the basic colors is used to generate pixel values of odd pixels of rows on the original, and a second sensor element for each of the basic colors is used to generate pixel values of even pixels of rows of the original. Each grey scale pixel value is generated mainly on the basis of a pixel value of at least one of the first sensor elements and a pixel value of at least one of the second sensor elements for adjacent pixels.
